Airway pressure release ventilation (APRV) is a pressure-controlled, time-cycled mode of intermittent mandatory ventilation. As well as mandatory breaths, spontaneous breaths can occur at any point throughout the respiratory cycle. These spontaneous breaths are...
APRV stands for ‘Airway Pressure Release Ventilation.’ It is a method based on the open lung theory that provides high mean airway pressures to promote alveolar recruitment while avoiding high driving pressure It allows the patient to breathe spontaneously across the...
Improved V/Q matching (probably most important factor) More uniform distribution of ventilation and perfusion Prevents atelectatic bases receiving highest blood flow A relative increase in functional residual capacity Reduction of cephalad pressure on the diaphragm...
FICM / ICSView Guideline ATS / ESICMView Guideline Recommendation Recommends the use of high PEEP strategies for patients with moderate or severe ARDS (Weak Recommendation) Recommend the use of higher rather than lower PEEP and recruitment manoeuvres in moderate to...
