Nenämaskin

Nenämaskin is a term used to describe a device designed to deliver breathable gas primarily through the nose. In medical contexts, nasal masks are used with therapies such as CPAP or BiPAP for sleep apnea, for supplemental oxygen delivery, and in some anesthesia or respiratory care settings. The mask connects to a gas source via a hose and is held in place by headgear that secures a seal around the nose.

Design and variants vary to balance comfort, seal, and function. Common materials include silicone, soft plastics, and gel cushions. The basic form is a nasal mask that fits over the nose, but variants exist such as nasal pillows, which use small cushions at the nostrils, and full-face masks that seal over both the nose and mouth. Features may include adjustable straps, soft edging to reduce skin irritation, anti-leak mechanisms, and compatibility with humidified gas.

Uses and operation: In sleep therapy, nenämaskin interfaces with noninvasive ventilators to maintain prescribed airway pressures. In clinical settings, it can deliver supplemental oxygen or be part of anesthetic gas delivery. Proper fitting is essential to minimize leaks and skin pressure injuries; regular cleaning and maintenance extend device life and reduce infection risk.

Safety and regulation: As a medical device, nenämaskin is subject to regulatory oversight in many jurisdictions. Users are advised to follow manufacturer instructions and clinician guidance regarding sizing, usage duration, cleaning, and replacement of parts.

History and context: Nasal interfaces have evolved since the late 20th century, with ongoing improvements aimed at comfort, seal quality, and patient adherence. See also CPAP, BiPAP, oxygen therapy, noninvasive ventilation.
