Both modalities stent open the alveoli in the lungs and thus, recruit more of the lung surface area for ventilation, but, while PEEP refers to devices that impose positive pressure only at the end of the exhalation, CPAP devices apply continuous positive airway pressure throughout the breathing cycle. The therapy is an alternative to positive end-expiratory pressure (PEEP). Some CPAP machines have other features as well, such as heated humidifiers. This constant stream of air opens and keeps the upper airway unobstructed during inhalation and exhalation. 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. Mechanism ĬPAP therapy uses machines specifically designed to deliver a flow of air at a constant pressure. Some people experience difficulty adjusting to CPAP therapy and report general discomfort, nasal congestion, abdominal bloating, sensations of claustrophobia, mask leak problems, and convenience-related complaints.

Other uses ĬPAP also has been suggested for treating acute hypoxaemic respiratory failure in children, however, due to a limited number of clinical studies, the effectiveness and safety of this approach to providing respiratory support is not clear. In March 2020, the USFDA suggested that CPAP devices may be used to support patients affected by COVID-19 however, they recommended additional filtration since non-invasive ventilation may increase the risk of infectious transmission. In resource-limited settings where CPAP improves respiratory rate and survival in children with primary pulmonary disease, researchers have found that nurses can initiate and manage care with once- or twice-daily physician rounds.

In some preterm infants whose lungs have not fully developed, CPAP improves survival and decreases the need for steroid treatment for their lungs. It is associated with a decrease in the incidence of bronchopulmonary dysplasia. For example, physicians may use CPAP in infants with respiratory distress syndrome. Pre-term infants ĬPAP also may be used to treat pre-term infants whose lungs are not yet fully developed.

CPAP can be used to treat UARS as the condition progresses, in order to prevent it from developing into obstructive sleep apnea. Upper airway resistance syndrome is another form of sleep-disordered breathing with symptoms that are similar to obstructive sleep apnea, but not severe enough to be considered OSA. In addition, a meta-analysis showed that CPAP therapy may reduce erectile dysfunction symptoms in male patients with obstructive sleep apnea. CPAP has been shown to be 100% effective at eliminating obstructive sleep apneas in the majority of people who use the therapy according to the recommendations of their physician. Medical uses Severe to moderate obstructive sleep apnea ĬPAP is the most effective treatment for moderate to severe obstructive sleep apnea, in which the mild pressure from the CPAP prevents the airway from collapsing or becoming blocked.
