A bed partner or family member may observe a person snoring or appear to stop breathing, gasp, or choke while sleeping. People who live or sleep alone are often unaware of the condition.
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.
The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea.
An orthography is a set of conventions for writing a language, including norms of spelling, punctuation, word boundaries, capitalization, hyphenation, and emphasis.. Most national and international languages have an established writing system that has undergone substantial standardization, thus exhibiting less dialect variation than the spoken language.

McGinnis developed the "Nasal CPAP Mask System," a continuous positive airway pressure (CPAP) machine for the treatment of sleep apnea, [3] based on the original 1981 design by Dr. Colin Sullivan. [4] After receiving FDA approval in 1984, Respironics began selling the first commercially available CPAP machine a year later. [5]
