Is there anything more frustrating in the ICU when you decide to start weaning a patient – they look like they’re assisting the ventilator. You switch them over to a “spontaneous” mode and then……nothing…..no breaths….eventually the backup starts.

This tutorial is about triggering of mechanical ventilation. I will revisit how patients trigger the ventilator, the different systems used and introduce I-Sync – a new method of triggering.

Finally I will discuss the problem of Auto-PEEP and explain why, in the setting of Auto-PEEP, there is no point fiddling with the flow by or negative pressure.

I guarantee you will learn something. @ccmtutorials www.ccmtutorials.org
