Ventilatory Assistance and Its Complications

Ventilatory emergencies occur when individuals are unable to ventilate their pulmonary gas-exchanging units adequately to meet metabolic needs. Preceding chapters have reviewed specific clinical respiratory emergencies that may require artificial mechanical ventilatory support when patients are critically ill. Whether the source of gas exchange impairment lies in airway obstruction, parenchymal infiltrate, vascular occlusion, pleural disease, or neuromuscular weakness, the final common pathway is ventilatory failure, which can be readily detected in the arterial blood gas (ABG). The PacO2 rises above 44, pH falls below 7.36, and the PaO2 falls below age-predicted or previously stable values.
