Make sure they are connected properly.Patients on positive end-expiratory pressure (PEEP) to maintain oxygenation, and require bag-valve-mask (BVM) ventilation during disconnection from mechanical ventilation, should be ventilated with a BVM containing a built-in PEEP valve or with a PEEP valve added to the exhalation port of the BVM.
