WebOn Hamilton Medical ventilators, ETS can be set to anywhere between 5% and 80%. In general, increasing the ETS setting results in a shorter inspiratory time, while decreasing it results in a longer inspiratory time. On other devices, this flow cycle mechanism is called ‘ESENS’, ‘End Inspiration’, ‘Flow Cycle’, etc. WebA short expiratory time constant. An expiratory time constant shorter than 0.5 s indicates a decrease in compliance, either due to the lung or the chest wall (see Figure 2). In ARDS patients, RCexp is typically in the range of 0.4 to 0.6 s. It is shorter in patients with more severe ARDS, indicating low compliance and a small volume of aerated ... modern luxury beauty salon design

No attention is given to the resultant high peak inspiratory flows (PIF), although it may impair secretion removal. It has been proposed that an expiratory flow … in real life wiki
