Which of the following alarms would be most important for a patient receiving positive pressure ventilation by a pressure-cycled ventilator? A. low volume B. high pressure C. I:E ratio D. low FIO2 - Answer A. low volume *If the patient is on a pressure cycle ventilator, that means the ventilator is going to deliver a certain pressure regardless of how much volume is achieved. If the ventilator does not care about volume, the practitioner must. Thus, the most important alarm for a pressu...
