Therefore, problems associated with the high PEEP alarm can generally be corrected by prolonging the patient’s expiratory time. This increases the patient’s work of breathing and can lead to respiratory distress. Auto-PEEP is a complication during mechanical ventilation when positive pressure remains in the alveoli at the end-exhalation phase of the breathing cycle. The high PEEP alarm most commonly sounds whenever auto-PEEP or air trapping is present. This alarm is useful in ensuring that too much PEEP isn’t delivered to the patient. High PEEP AlarmĪ high PEEP alarm in mechanical ventilation is triggered whenever the level of PEEP exceeds a preset high PEEP limit. If this occurs, the respiratory therapist must ensure that the patient is being ventilated by delivering manual breaths until the source of the disconnection is identified and corrected. The sounding of the apnea alarm most commonly occurs whenever there is a disconnection of the circuit from the endotracheal tube.
