Single level respirator: have another name called continuous positive pressure breathing machine, the treatment pressure of this respirator is the invariable pressure setting.Because need to lower some pressure when exhaling, be conducive to the waste gas discharge in lung, but single level respirator output pressure is constant continuous positive pressure, is unfavorable for waste gas discharge; When air-breathing, need to increase flow and keep pressure, but now single level respirator output pressure still remains unchanged.This constant output pressure does not mate mutually with patient's breathing, cause patient to do not feel like oneself, especially patient's sense of discomfort when expiratory phase is the most obvious, so all putting forward the breath pressure of oneself, a lot of companies discharge solution, and usually hat is applied for a patent by some special-purpose titles, for example the EPRTM of " Rui Simai " exhales and discharges easily breathing, " Bi-FlexTM " of " Philip ", the RESlsx of " Rui Maite ".
Two level respirators: be for patient provides the higher pressure of inspiration(Pi) that sets and lower expiratory pressure, conversion automatically in patient respiratory process.Level respirator adopts different pressures of inspiration(Pi) and expiratory pressure, has improved to greatest extent treatment comfortableness.But trigger speed and each company of sensitivity of switching and adopt different designs, roughly have capacity triggering, freely air-breathing thresholding triggering, pressure activated, figure triggering etc.
