If the symptoms are severe enough, treatment may be needed. These range from medical management over mechanical ventilation (both continuous positive airway pressure (CPAP), or bi-level positive airway pressure (BiPAP) to tracheal stenting and surgery.

Surgical techniques include aortopexy, tracheopexy, tracheobronchoplasty, and tracheostomy. The role of the nebulised recombinant human deoxyribonuclease (rhDNase) remains inconclusive.

Treatment is directed at correcting the underlying cause. Post-surgical atelectasis is treated by physiotherapy, focusing on deep breathing and encouraging coughing. An incentive spirometer is often used as part of the breathing exercises. Walking is also highly encouraged to improve lung inflation. People with chest deformities or neurologic conditions that cause shallow breathing for long periods may benefit from mechanical devices that assist their breathing. One method is continuous positive airway pressure, which delivers pressurized air or oxygen through a nose or face mask to help ensure that the alveoli do not collapse, even at the end of a breath. This is helpful, as partially inflated alveoli can be expanded more easily than collapsed alveoli. Sometimes additional respiratory support is needed with a mechanical ventilator.

The primary treatment for acute massive atelectasis is correction of the underlying cause. A blockage that cannot be removed by coughing or by suctioning the airways often can be removed by bronchoscopy. Antibiotics are given for an infection. Chronic atelectasis is often treated with antibiotics because infection is almost inevitable. In certain cases, the affected part of the lung may be surgically removed when recurring or chronic infections become disabling or bleeding is significant. If a tumor is blocking the airway, relieving the obstruction by surgery, radiation therapy, chemotherapy, or laser therapy may prevent atelectasis from progressing and recurrent obstructive pneumonia from developing.

There are many advanced medical treatments to relieve choking or airway obstruction. These include inspection of the airway with a laryngoscope or bronchoscope and removal of the object under direct vision. Severe cases where there is an inability to remove the object may require cricothyrotomy (emergency tracheostomy). Cricothyrotomy involves making an incision in a patient's neck and inserting a tube into the trachea in order to bypass the upper airways. The procedure is usually only performed when other methods have failed. In many cases, an emergency tracheostomy can save a patient's life, but if performed incorrectly, it may end the patient’s life.

If the person is awake and able to breathe often all that is requires is providing extra oxygen while the operating room is prepared for bronchoscopy.

If a children less than one and is unable to breathe at all then five back blows followed by five chest thrusts should be done. In children over the age of one abdominal thrusts are recommended.

If this is not effective than bag mask ventilation is recommended. Next laryngoscopy can be tried to look and see if the foreign body can be removed. If the above is not effective than intubation or cricothyrotomy can be tried.

Therapeutic interventions with medium-chain triglyceride-enriched low-fat diets, intratracheal heparin, inhaled tissue plasminogen activator, and steroids have also been reported and have met with variable success.

Inhaled mucolytics: Potassium iodide and acetylcysteine inhaled therapy are often used to help the patient cough up the casts by breaking down the thick mucus formations.

Inhaled and oral steroids: If PB is associated with asthma or an infection, inhaled and oral steroids have been shown to be effective.

If the choking victim becomes unconscious, the American Medical Association advocates sweeping the fingers across the back of the throat to attempt to dislodge airway obstructions, However, many modern protocols recommend against the use of the finger sweep since, if the patient is conscious, they will be able to remove the foreign object themselves, or if they are unconscious, the rescuer should simply place them in the recovery position as this allows (to a certain extent) the drainage of fluids out of the mouth instead of down the trachea due to gravity. There is also a risk of causing further damage (for instance inducing vomiting) by using a finger sweep technique. There are no studies that have examined the usefulness of the finger sweep technique when there is no visible object in the airway. Recommendations for the use of the finger sweep have been based on anecdotal evidence.

Acute therapy for PB is often focused on removal or facilitated expectoration of the casts. This is followed by short and long term efforts to identify and remediate the underlying condition resulting in the excessive airway leakage or inflammation that is causing the casts to form.

PB can present as a life threatening emergency when the casts obstruct the major airways resulting in acute respiratory distress. Intervention by a skilled physician experienced with foreign body removal from the lungs is essential. Evaluation by means of bronchoscopy can be difficult and time consuming and is best performed under general anesthesia.

Casts can be removed mechanically by bronchoscopy or physical therapy. High-frequency chest wall oscillation can also be used to vibrate the chest wall at a high frequency to try to loosen and thin the casts. Inhaled therapy using bronchodilators, corticosteroids or mucolytics can be used to try to disrupt the cast formation.

Recently, heavy T2-weighted MRI has revealed that occult lymphatic anomalies that represent developmental remnants or subclinical GLA are present in adults who present with expectoration of large multiantennary, branching casts. Intranodal lymphangiogram and dynamic contrast-enhanced MR lymphangiography have been used to more precisely image the leaks, and in the small number of patients who have been treated to date, embolization of the TD has been highly successful in controlling cast formation.

Cannulation of the thoracic duct followed by embolization should be considered in those patients who are shown to have leakage of lymphatic fluid into the airway.

The initial management of pulmonary edema, irrespective of the type or cause, is supporting vital functions. Therefore, if the level of consciousness is decreased it may be required to proceed to tracheal intubation and mechanical ventilation to prevent airway compromise. Hypoxia (abnormally low oxygen levels) may require supplementary oxygen, but if this is insufficient then again mechanical ventilation may be required to prevent complications. Treatment of the underlying cause is the next priority; pulmonary edema secondary to infection, for instance, would require the administration of appropriate antibiotics.

Acute cardiogenic pulmonary edema often responds rapidly to medical treatment. Positioning upright may relieve symptoms. Loop diuretics such as furosemide or bumetanide are administered, often together with morphine or diamorphine to reduce respiratory distress. Both diuretics and morphine may have vasodilator effects, but specific vasodilators may be used (particularly intravenous glyceryl trinitrate or ISDN) provided the blood pressure is adequate.

Continuous positive airway pressure and bilevel positive airway pressure (BIPAP/NIPPV) has been demonstrated to reduce the need of mechanical ventilation in people with severe cardiogenic pulmonary edema, and may reduce mortality.

It is possible for cardiogenic pulmonary edema to occur together with cardiogenic shock, in which the cardiac output is insufficient to sustain an adequate blood pressure. This can be treated with inotropic agents or by intra-aortic balloon pump, but this is regarded as temporary treatment while the underlying cause is addressed.

The optimal management of laryngotracheal stenosis is not well defined, depending mainly on the type of the stenosis.

General treatment options include

1. Tracheal dilation using rigid bronchoscope

2. Laser surgery and endoluminal stenting

3. Tracheal resection and laryngotracheal reconstructionr

Tracheal is used to temporarily enlarge the airway. The effect of dilation typically lasts from a few days to 6 months. Several studies have shown that as a result of mechanical dilation (used alone) may occur a high mortality rate and a rate of recurrence of stenosis higher than 90%.

Thus, many authors treat the stenosis by endoscopic excision with laser (commonly either the carbon dioxide or the neodymium: yttrium aluminum garnet laser) and then by using bronchoscopic dilatation and prolonged stenting with a T-tube (generally in silicone).

There are differing opinions on treating with laser surgery.

In very experienced surgery centers, tracheal resection and reconstruction (anastomosis complete end-to-end with or without laryngotracheal temporary stent to prevent airway collapse) is currently the best alternative to completely cure the stenosis and allows to obtain good results. Therefore, it can be considered the gold standard treatment and is suitable for almost all patients.

The narrowed part of the trachea will be cut off and the cut ends of the trachea sewn together with sutures. For stenosis of length greater than 5 cm a stent may be required to join the sections.

Late June or early July 2010, a new potential treatment was trialed at Great Ormond Street Hospital in London, where Ciaran Finn-Lynch (aged 11) received a transplanted trachea which had been injected with stem cells harvested from his own bone marrow. The use of Ciaran's stem cells was hoped to prevent his immune system from rejecting the transplant, but there remain doubts about the operation's success, and several later attempts at similar surgery have been unsuccessful.

Interventions include intravenous (IV) medications (e.g. magnesium sulfate), aerosolized medications to dilate the airways (bronchodilation) (e.g., albuterol or ipratropium bromide/salbutamol), and positive-pressure therapy, including mechanical ventilation. Multiple therapies may be used simultaneously to rapidly reverse the effects of status asthmaticus and reduce permanent damage of the airways. Intravenous corticosteroids and methylxanthines are often given. If the person with a severe asthma exacerbation is on a mechanical ventilator, certain sedating medications such as ketamine or propofol, have bronchodilating properties. According to a new randomized control trial ketamine and aminophylline are also effective in children with acute asthma who responds poorly to standard therapy.

Time is the only treatment necessary in more than 90% of infant cases. In other cases, surgery may be necessary. Most commonly, this involves cutting the aryepiglottic folds to let the supraglottic airway spring open. Trimming of the arytenoid cartilages or the mucosa/ tissue over the arytenoid cartilages can also be performed as part of the supraglottoplasty. Supraglottoplasty can be performed bilaterally (on both the left and right sides at the same time), or be staged where only one side is operated on at a time.

Treatment of gastroesophageal reflux disease can also help in the treatment of laryngomalacia, since gastric contents can cause the back part of the larynx to swell and collapse even further into the airway.

In some cases, a temporary tracheostomy may be necessary.

The lungs are normally protected against aspiration by a series of "protective reflexes" such as coughing and swallowing. Significant aspiration can only occur if the protective reflexes are absent or severely diminished (in neurological disease, coma, drug overdose, sedation or general anesthesia). In intensive care, sitting patients up reduces the risk of pulmonary aspiration and ventilator-associated pneumonia.

Measures to prevent aspiration depend on the situation and the patient. In patients at imminent risk of aspiration, tracheal intubation by a trained health professional provides the best protection. A simpler intervention that can be implemented is to lay the patient on their side in the recovery position (as taught in first aid and CPR classes), so that any vomitus produced by the patient will drain out their mouth instead of back down their pharynx. Some anesthetists will use sodium citrate to neutralize the stomach's low pH and metoclopramide or domperidone (pro-kinetic agents) to empty the stomach.

People with chronic neurological disorders, for example, after a stroke, are less likely to aspirate thickened fluids.

The location of abscesses caused by aspiration depends on the position one is in. If one is sitting or standing up, the aspirate ends up in the posterior basal segment of the right lower lobe. If one is on one's back, it goes to the superior segment of the right lower lobe. If one is lying on the right side, it goes to the posterior segment of the right upper lobe, or the posterior basal segment of the right upper lobe. If one is lying on the left, it goes to the lingula.

Laryngomalacia becomes symptomatic after the first few months of life (2–3 months), and the stridor may get louder over the first year, as the child moves air more vigorously. Most of the cases resolve spontaneously and less than 15% of the cases will need surgical intervention. Parents need to be supported and educated about the condition.

So far, there is no certain treatment that can completely stop snoring. Almost all treatments for snoring revolve around lessening the breathing discomfort by clearing the blockage in the air passage. Medications are usually not helpful in treating snoring symptoms, though they can help control some of the underlying causes such as nasal congestion and allergic reactions. Doctors, therefore, often recommend lifestyle changes as a first line treatment to stop snoring. This is the reason snorers are advised to lose weight (to stop fat from pressing on the throat), stop smoking (smoking weakens and clogs the throat), avoid alcohol and sedative medications before bedtime (they relax the throat and tongue muscles, which in turn narrow the airways) and sleep on their side (to prevent the tongue from blocking the throat).

A number of other treatment options are also used to stop snoring. These range from over-the-counter aids such as nasal sprays, nasal strips or nose clips, lubricating sprays, oral appliances and "anti-snore" clothing and pillows, to unusual activities such as playing the didgeridoo. However, one needs to be wary of over-the-counter snore treatments that have no scientific evidence to support their claims, such as stop-snore rings or wrist worn electrical stimulation bands.

Positive airway pressure, initially in the form of "continuous" positive airway pressure (CPAP), is a useful treatment for obesity hypoventilation syndrome, particularly when obstructive sleep apnea co-exists. CPAP requires the use during sleep of a machine that delivers a continuous positive pressure to the airways and preventing the collapse of soft tissues in the throat during breathing; it is administered through a mask on either the mouth and nose together or if that is not tolerated on the nose only (nasal CPAP). This relieves the features of obstructive sleep apnea and is often sufficient to remove the resultant accumulation of carbon dioxide. The pressure is increased until the obstructive symptoms (snoring and periods of apnea) have disappeared. CPAP alone is effective in more than 50% of people with OHS.

In some occasions, the oxygen levels are persistently too low (oxygen saturations below 90%). In that case, the hypoventilation itself may be improved by switching from CPAP treatment to an alternate device that delivers "bi-level" positive pressure: higher pressure during inspiration (breathing in) and a lower pressure during expiration (breathing out). If this too is ineffective in increasing oxygen levels, the addition of oxygen therapy may be necessary. As a last resort, tracheostomy may be necessary; this involves making a surgical opening in the trachea to bypass obesity-related airway obstruction in the neck. This may be combined with mechanical ventilation with an assisted breathing device through the opening.

General treatment principles are removal from exposure, protection of the airway (i.e., preemptive intubation), and treatment of hypoxemia. Concomitant airway injury with acute bronchospasm often warrants treatment with bronchodilators because of the airway obstruction.

A beneficial role for corticosteroids has not been established by controlled trials in humans. Despite the lack of controlled evidence of efficacy, anecdotal reports of benefits from systemic corticosteroid use continue to appear.

Prophylactic antibiotic drugs have not proved to be efficacious in toxic lung injury. Antibiotics should be reserved for those patients with clinical evidence of infection.

Airway obstruction may cause obstructive pneumonitis or post-obstructive pneumonitis.

Treatment is with corticosteroids and possibly intravenous immunoglobulins.

In people with stable OHS, the most important treatment is weight loss—by diet, through exercise, with medication, or sometimes weight loss surgery (bariatric surgery). This has been shown to improve the symptoms of OHS and resolution of the high carbon dioxide levels. Weight loss may take a long time and is not always successful. Bariatric surgery is avoided if possible, given the high rate of complications, but may be considered if other treatment modalities are ineffective in improving oxygen levels and symptoms. If the symptoms are significant, nighttime positive airway pressure (PAP) treatment is tried; this involves the use of a machine to assist with breathing. PAP exists in various forms, and the ideal strategy is uncertain. Some medications have been tried to stimulate breathing or correct underlying abnormalities; their benefit is again uncertain.

While many people with obesity hypoventilation syndrome are cared for on an outpatient basis, some deteriorate suddenly and when admitted to the hospital may show severe abnormalities such as markedly deranged blood acidity (pH<7.25) or depressed level of consciousness due to very high carbon dioxide levels. On occasions, admission to an intensive care unit with intubation and mechanical ventilation is necessary. Otherwise, "bi-level" positive airway pressure (see the next section) is commonly used to stabilize the patient, followed by conventional treatment.

One treatment for obstructive hypopnea is continuous positive airway pressure (CPAP). CPAP is a treatment in which the patient wears a mask over the nose and/or mouth. An air blower forces air through the upper airway. The air pressure is adjusted so that it is just enough to maintain the oxygen saturation levels in the blood. Another treatment is sometimes a custom fitted oral appliance. The American Academy of Sleep Medicine's protocol for obstructive sleep apnea (OSA) recommends oral appliances for those who prefer them to CPAP and have mild to moderate sleep apnea or those that do not respond to/cannot wear a CPAP. Severe cases of OSA may be treated with an oral appliance if the patient has had a trial run with a CPAP. Oral Appliances should be custom made by a dentist with training in dental sleep medicine. Mild obstructive hypopnea can often be treated by losing weight or by avoiding sleeping on one's back. Also quitting smoking, and avoiding alcohol, sedatives and hypnotics (soporifics) before sleep can be quite effective. Surgery is generally a last resort in hypopnea treatment, but is a site-specific option for the upper airway. Depending on the cause of obstruction, surgery may focus on the soft palate, the uvula, tonsils, adenoids or the tongue. There are also more complex surgeries that are performed with the adjustment of other bone structures - the mouth, nose and facial bones.

Orthopedic pillows are the least intrusive option for reducing snoring. These pillows are designed to support the head and neck in a way that ensures the jaw stays open and slightly forward. This helps keep the airways unrestricted as possible and in turn leads to a small reduction in snoring.

Several methods of treatment are available, mainly consisting of careful drug therapy and surgery. Glucocorticoids (such as prednisone or methylprednisolone) decrease the inflammatory response to tumor invasion and edema surrounding the tumor. Glucocorticoids are most helpful if the tumor is steroid-responsive, such as lymphomas. In addition, diuretics (such as furosemide) are used to reduce venous return to the heart which relieves the increased pressure.

In an acute setting, endovascular stenting by an interventional radiologist may provide relief of symptoms in as little as 12–24 hours with minimal risks.

Should a patient require assistance with respiration whether it be by bag/valve/mask, BiPAP, CPAP or mechanical ventilation, extreme care should be taken. Increased airway pressure will tend to further compress an already compromised SVC and reduce venous return and in turn cardiac output and cerebral and coronary blood flow. Spontaneous respiration should be allowed during endotracheal intubation until sedation allows placement of an ET tube and reduced airway pressures should be employed when possible.

Treatment of TBI varies based on the location and severity of injury and whether the patient is stable or having trouble breathing, but ensuring that the airway is patent so that the patient can breathe is always of paramount importance. Ensuring an open airway and adequate ventilation may be difficult in people with TBI. Intubation, one method to secure the airway, may be used to bypass a disruption in the airway in order to send air to the lungs. If necessary, a tube can be placed into the uninjured bronchus, and a single lung can be ventilated. If there is a penetrating injury to the neck through which air is escaping, the trachea may be intubated through the wound. Multiple unsuccessful attempts at conventional (direct) laryngoscopy may threaten the airway, so alternative techniques to visualize the airway, such as fiberoptic or video laryngoscopy, may be employed to facilitate tracheal intubation. If the upper trachea is injured, an incision can be made in the trachea (tracheotomy) or the cricothyroid membrane (cricothyrotomy, or cricothyroidotomy) in order to ensure an open airway. However, cricothyrotomy may not be useful if the trachea is lacerated below the site of the artificial airway. Tracheotomy is used sparingly because it can cause complications such as infections and narrowing of the trachea and larynx. When it is impossible to establish a sufficient airway, or when complicated surgery must be performed, cardiopulmonary bypass may be used—blood is pumped out of the body, oxygenated by a machine, and pumped back in. If a pneumothorax occurs, a chest tube may be inserted into the pleural cavity to remove the air.

People with TBI are provided with supplemental oxygen and may need mechanical ventilation. Employment of certain measures such as Positive end-expiratory pressure (PEEP) and ventilation at higher-than-normal pressures may be helpful in maintaining adequate oxygenation. However, such measures can also increase leakage of air through a tear, and can stress the sutures in a tear that has been surgically repaired; therefore the lowest possible airway pressures that still maintain oxygenation are typically used. Mechanical ventilation can also cause pulmonary barotrauma when high pressure is required to ventilate the lungs. Techniques such as pulmonary toilet (removal of secretions), fluid management, and treatment of pneumonia are employed to improve pulmonary compliance (the elasticity of the lungs).

While TBI may be managed without surgery, surgical repair of the tear is considered standard in the treatment of most TBI. It is required if a tear interferes with ventilation; if mediastinitis (inflammation of the tissues in the mid-chest) occurs; or if subcutaneous or mediastinal emphysema progresses rapidly; or if air leak or large pneumothorax is persistent despite chest tube placement. Other indications for surgery are a tear more than one third the circumference of the airway, tears with loss of tissue, and a need for positive pressure ventilation. Damaged tissue around a rupture (e.g. torn or scarred tissue) may be removed in order to obtain clean edges that can be surgically repaired. Debridement of damaged tissue can shorten the trachea by as much as 50%. Repair of extensive tears can include sewing a flap of tissue taken from the membranes surrounding the heart or lungs (the pericardium and pleura, respectively) over the sutures to protect them. When lung tissue is destroyed as a result of TBI complications, pneumonectomy or lobectomy (removal of a lung or of one lobe, respectively) may be required. Pneumonectomy is avoided whenever possible due to the high rate of death associated with the procedure. Surgery to repair a tear in the tracheobronchial tree can be successful even when it is performed months after the trauma, as can occur if the diagnosis of TBI is delayed. When airway stenosis results after delayed diagnosis, surgery is similar to that performed after early diagnosis: the stenotic section is removed and the cut airway is repaired.

Airway obstruction is a blockage of respiration in the airway. It can be broadly classified into being either in the upper airway or lower airway.
