Many complication occur on bed, it is common to there is drainage tube opening on trachea cannula to be blocked by tunica mucosa tracheae or phlegm scab and cause to have
Effect removes secretion, next pressure crosses conference and causes cough reflex, heart rate and blood oxygen saturation variation, causes respiratory mucosa
Damage, document report use the complication for attracting technology (CASS technologies) to cause the visible hemorrhage in respiratory tract of naked eyes under duration glottis
Incidence is 7.1%, this causes it not to be widely used clinically.
And technology, i.e. operated by two people are rushed for the most frequently used air-flow：One people's crushing failure at high speed bag respirator, a people quickly give gas
Capsule is deflated and inflation, if the uncoordinated retentate that often leads to of double cooperation slides into deep breathing road, but also is unable to monitor extruding letter
The airway pressure that easy respirator generates, excessively high airway pressure often lead to patient's wind-contusion and are fought with autonomous respiration；Especially for stubbornness
Property hypoxemia patient, if using disconnect lung ventilator and double compounding practice bag respirator removed with air bag it is stagnant on air bag
The method for staying object, often the long period, which interrupts mechanical ventilation and low concentration oxygen supply, will lead to the more serious anaerobic condition of patient, and
And Reusability bag respirator also increases the chance of cross-infection.
