C-Pap

Continuous positive airway pressure(CPAP) is a form of正气道压力ventilator, which applies mild air pressure on a continuous basis to keep the airways continuously open in people who are able to breathe spontaneously on their own. It is an alternative topositive end-expiratory pressure(观察)。这两种形式支架lungs’alveoli打开，从而招募更多的肺表面积进行通风。但是，尽管PEEP是指仅在末尾施加正压的设备exhalation，应用CPAP设备continuous正气道压力throughout the breathing cycle. Thus, the ventilator itself does not cycle during CPAP, no additional pressure above the level of CPAP is provided, and patients must initiate all of their breaths.^[1]

CPAP typically is used for people who have breathing problems, such assleep apnea。CPAP also may be used to treat preterm infants whose lungs have not yet fully developed. For example, physicians may use CPAP in infants withrespiratory distress syndrome。它与降低的发生率有关bronchopulmonary dysplasia。In some preterm infants whose lungs haven’t fully developed, CPAP improves survival and decreases the need for steroid treatment for their lungs. 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.^[2]

CPAP therapy utilizes machines specifically designed to deliver a constant flow of pressure. Some CPAP machines have other features as well, such as heated humidifiers. CPAP is the most effective treatment forobstructive sleep apnea, in which the mild pressure from the CPAP prevents the airway from collapsing or becoming blocked.^[3]

虽然交付CPAP通过鼻罩the most common modality of treatment, other systems exist for interfacing with adults and children. Nasal CPAP is frequently used in infants, though its use is controversial. Studies have shown nasal CPAP reduces ventilator time but an increased occurrence ofpneumothoraxwas also prevalent.^[4]Oral masks and naso-oral masks are often used when nasal congestion or obstruction is an issue. Devices that combine nasal pressure withmaxillary advancement devices(MAD) also exist.
