More recently, ventilator... Witryna2 lip 2024 · Extubation readiness testing (ERT) (i.e. a formal trial of spontaneous breathing) is a key component in the process of discontinuing mechanical ventilation (MV). ERTs can be done using continuous positive airway pressure (CPAP) with or without added pressure support (PS) or with a T-piece. Witryna1 kwi 1995 · The imposed work of breathing (work performed by the patient to breathe spontaneously through the breathing apparatus, ie. the endotracheal tube and ventilator breath- ing circuit and demand-flow system) is an addmonal flow- resistive workload superimposed on the physiologic work.i4-16 Imposed work may equal or exceed the … chrysler 300 awd 2014
