CPAP also may be used to treat pre-term infants whose lungs are not yet fully developed. For example, physicians may use CPAP in infants with respiratory distress syndrome. It is associated with a decrease in the incidence of bronchopulmonary dysplasia. In some preterm infants whose lungs have not fully developed, CPAP improves survival and ...
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.
Corresponding pressure and flow curves during one cycle of inflationdeflation. Notice the flow curve goes back to zero at the end of inflation, indicating full lung inflation; and also goes back to zero during the release period before inflation starts, indicating complete gas exhalation with no intrinsic PEEP.

Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
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.
Ventilation is normally unconscious and automatic, but can be overridden by conscious alternative patterns. [3] Thus the emotions can cause yawning, laughing, sighing (etc.), social communication causes speech, song and whistling, while entirely voluntary overrides are used to blow out candles, and breath holding (for instance, to swim underwater).
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. [1]
The BVM consists of a mask attached to a shutter valve. The valve allows air to flow into the lungs but prevents air from the lungs from filling the bag for the next breath. This prevents rebreathing of air with low oxygen. The bag inflates with room air, or it can be attached to bottled oxygen.
