Low inspiratory pressure alarms will sound because of altered settings, unattached tubing or a leak around the endotracheal tube (ETT), the ETT displaced into the pharynx or esophagus, poor cuff inflation or leak, tracheoesophageal fistula, peak flows that are too low, low tidal volume (Vt), decreased airway resistance resulting from decreased secretions or relief of bronchospasm, increased lung compliance resulting from decreased atelectasis, reduction in pulmonary edema, resolution of ARDS, or a change in position.High-pressure alarms will sound because of improper alarm setting; airway obstruction resulting from patient fighting ventilator (holding breath as ventilator delivers Vt); patient circuit collapse; kinked tubing; the ETT in the right mainstem bronchus or against the carina; cuff herniation; increased airway resistance resulting from bronchospasm, airway secretions, plugs, and coughing; water from the humidifier in the ventilator tubing; and decreased lung compliance resulting from tension pneumothorax, change in patient position, acute respiratory distress syndrome, pulmonary edema, atelectasis, pneumonia, or abdominal distention.
