COMPARE-VENT Feasibility Pilot Study
Recruiting now · Not applicable
Conditions studied: Respiration Failure, Cardio Vascular Disease, Cardiogenic Pulmonary Oedema, Critical Illness, Mechanical Ventilation, Cardiogenic Shock, Cardiopulmonary
In brief
Cardiac disease complicated by respiratory insufficiency comprises the most frequent indication for cardiac intensive care unit (CICU) admission, with nearly one-third patients requiring advanced respiratory support and over 20% patients requiring invasive mechanical ventilation (IMV). IMV among patients with impaired cardiovascular reserve is further compounded by the adverse impact of positive pressure ventilation (PPV) and systemic sedation on intracardiac hemodynamics, pulmonary vascular mechanics and consequently end-organ perfusion. Despite widespread use, evidence guiding optimal ventilatory practices and mode selection in cardiovascular intensive care unit patients remains limited. Pressure-controlled and volume-controlled ventilation may differ in their effects on patient-ventilator synchrony, sedation requirements, and hemodynamic impact, but comparative data among patients with critical cardiac disease remains inconclusive. This pilot study will evaluate the feasibility of implementing a pragmatic cluster-randomized crossover trial comparing ventilatory modes in a contemporary cardiovascular intensive care unit.
