Continuous positive airway pressure (CPAP) is a form of positive airway pressure ventilator, which applies mild air pressure on a continuous basis. It keeps the airways continuously open in people who are able to breathe spontaneously on their own, but need help keeping their airway unobstructed. It is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent the lungs' alveoli open and thus recruit more of the lung's 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. 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]
https://www.israel21c.org/new-ventilator-mask-protects-entire-face-from-coronavirus/ Many people are wearing facemasks to avoid breathing airborne coronavirus particles, and to keep from touching their noses and mouths. However, even N95 masks can’t fully block tiny virus particles and can’t kill the virus (two masks under development in Israel aim to do that). Any blocked viral particles stay on the mask’s surface and pose a hazard when handled and thrown away. Furthermore, facemasks don’t cover eyes. Although the nose is the main route for coronavirus into the lungs, some researchers believe the eye’s conjunctiva is another possible point of entry. That’s why Israeli physician and serial medical-device inventor Dr. Noam Gavriely worked quickly to develop what he calls the ViriMASK Protective Oculo-Respirator . ViriMASK is strapped around the head, covering the eyes with a see-through visor and the nose and mouth with a filtering mechanism....
