A 60-year-old woman on ICU with ARDS is ventilated. The physiotherapist asks about performing manual hyperinflation (MHI, 'bagging') to clear secretions. What are the potential risks of MHI in a patient with ARDS on high PEEP?AMHI has no risksBMHI risks include: loss of PEEP during circuit disconnection causing rapid derecruitment and desaturation; delivery of uncontrolled and potentially excessive tidal volumes and pressures causing VILI; haemodynamic instability from pressure swings; and inability to monitor delivered pressures accuratelyCMHI always improves oxygenationDMHI is the preferred secretion clearance technique in ARDSEMHI is identical to ventilator-delivered breathsCheck my answer
