  • Title: Second- and third-generation ventilators: sorting through available options. When, and for which patients, are special functions needed?
    Author: Bone RC, Eubanks DH.
    Journal: J Crit Illn; 1992 Mar; 7(3):399-416. PubMed ID: 10148162.
    Abstract:
    Currently available ventilators offer a number of special options to meet the needs of critically ill patients. Intermittent mandatory ventilation allows a patient to breathe spontaneously without assistance. CPAP and PEEP ensure that the patient breathes at an elevated pressure either constantly or during expiration. Pressure support ventilation allows patients to participate in breathing but provides inspiratory assistance and is most useful during weaning. Airway pressure release ventilation facilitates venous return and decreases airway pressure. Sophisticated monitors provide detailed information on the patient's status, but alarm features are somewhat unreliable. Thorough knowledge of the controls on modern ventilators can help you provide the optimum form of respiratory support.
