Positive-pressure ventilation can be life saving, but complications such as toxic effects of oxygen, laryngeal injury, tracheal stenosis, alveolar injury, barotrauma, pneumonia, and psychological problems may occur. Menu. Ventilatory support that provides mechanical breaths when the patient's spontaneous breathing does not achieve the preset mechanical ventilatory rate. Chest rise, … In emergency cardiac or critical care, the administration of artificial breaths to a patient that are timed independently of chest compressions. This is called mechanical ventilation.

This form of ventilation is used for patients with an upper airway obstruction who cannot be intubated. Inhaled gases are given with positive end-expiratory pressure often with pressure support or with assist control ventilation at a set tidal volume and rate.
