CPAP machines possess a motor that pressurizes room temperature air and delivers it through a hose connected to a mask or tube worn by the patient. This constant stream of air opens and keeps the upper airway unobstructed during inhalation and exhalation. [1] Some CPAP machines have other features as well, such as heated humidifiers.
Positive airway pressure (PAP) is a mode of respiratory ventilation used in the treatment of sleep apnea.PAP ventilation is also commonly used for those who are critically ill in hospital with respiratory failure, in newborn infants (), and for the prevention and treatment of atelectasis in patients with difficulty taking deep breaths.
Aerophagia (or aerophagy) is a condition of excessive air swallowing, which goes to the stomach instead of the lungs.Aerophagia may also refer to an unusual condition where the primary symptom is excessive flatus (farting), belching (burping) is not present, and the actual mechanism by which air enters the gut is obscure or unknown.

Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand.
Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide. Mechanical ventilation is used for many reasons, including to protect the airway due to mechanical or neurologic cause, to ensure adequate oxygenation, or to remove excess carbon dioxide from the ...
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
Glossopharyngeal insufflation is a breathing technique that consists of gulping boluses of air into the lungs. It is also used by breath-hold divers to increase their lung volumes. [5] Positive airway pressure is a mode of mechanical or artificial ventilation based on insufflation. [citation needed]
Normal atmospheric air contains approximately 21% oxygen when inhaled. After gaseous exchange has taken place in the lungs, with waste products (notably carbon dioxide) moved from the bloodstream to the lungs, the air being exhaled by humans normally contains around 17% oxygen. This means that the human body utilises only around 19% of the ...
