  • Title: Pressure support ventilation (PSV) reverses hyperinflation induced isorhythmic A-V dissociation.
    Author: Conti G, Bufi M, Antonelli M, Rocco M, Gasparetto A.
    Journal: Intensive Care Med; 1989; 15(5):319-21. PubMed ID: 2671080.
    Abstract:
    We report a case of hyperinflation induced isorythmic atrio-ventricular dissociation with circulatory failure in a patient with chronic obstructive pulmonary disease. The arrythmia was successfully treated by applying "pressure support ventilation" (PSV: 20 cmH2O) which, by decreasing the respiratory rate and increasing the expiratory time reduced the level of auto-PEEP. In order to explain this result the Authors recorded, in the same patient, the level of auto-PEEP and delta FRC obtained with Intermittent Positive Pressure Ventilation (IPPV), Intermittent Mandatory Ventilation (IMV) and PSV at the same gas exchange values. PSV showed a dramatic reduction of both these parameters. (Auto-PEEP: IPPV 12 cmH2O, IMV 17 cmH2O, PSV 7 cmH2O).
