Abstract
Most patients undergoing mechanical ventilation (MV) in critical care units are liberated from the ventilator within a median of 7 days. Unfortunately, some patients experience difficulty in liberation from MV during their ICU stays and require extended time on MV. It has been estimated that 40% of the patient's duration on the ventilator is spent weaning.[1] Moreover, although patients requiring prolonged mechanical ventilation represent approximately 6% of all ventilated patients, they consume 37% of intensive care unit resources.[2] Therefore, accelerating the liberation of prolonged weaning patients from MV improves patient care and could yield significant economic benefits.
Highlights
Most patients undergoing mechanical ventilation (MV) in critical care units are liberated from the ventilator within a median of 7 days
Proportional Assist Ventilation (PAV+) has many aspects that are theoretically beneficial as part of a difficult weaning protocol
Over the 39 month (3.25 year) period 46 patients underwent a slow wean, 40 of whom spent greater than 70% of their time weaning in a PAV+ mode
Summary
Most patients undergoing mechanical ventilation (MV) in critical care units are liberated from the ventilator within a median of 7 days. [2] accelerating the liberation of prolonged weaning patients from MV improves patient care and could yield significant economic benefits. Length of Hospital Stay (days) median (IQR)
