Why does my ventilator alarm sound?
An alarm will sound if the ventilator exceeds or drops below certain limits. Always look at and attend to the patient first. Address the alarm situation second. Low pressure alarm: Indicates that the pressure in the ventilator circuit has dropped.

What is the most common trigger for apnea alarm?
Low exhaled volume alarms are triggered by air leaks. These are most frequently secondary to ventilatory tubing disconnect from the patient’s tracheal tube but will also occur in the event of balloon deflation or tracheal tube dislodgement.
What causes high PEEP alarm on ventilator?
Some causes for high pressure alarms are: Water in the ventilator circuit. Increased or thicker mucus or other secretions blocking the airway (caused by not enough humidity) Bronchospasm. Coughing, gagging, or “fighting” the ventilator breath.
How can nuisance alarms be avoided on the ventilator?
An appropriate combination of tidal volume and inspiratory time and an appropriate setting of alarms may avoid nuisance alarm activation.

Patients are unable to vocalize during mechanical ventilation due to the breathing tube. Also, ventilated patients may be sedated or have fluctuating consciousness; their ability to comprehend or attend to communications may also fluctuate.
How do you fix high PEEP on a ventilator?
Treating auto-PEEP
- Decreasing respiratory rate will increase the time between breaths and decrease the inspiratory to expiratory (I:E) ratio to 1:3 to 1:5.
- Increasing the inspiratory rate to 60 to 100 L/min will assure fast delivery of air during inspiration, lending more time for exhalation.
