Key result
PEEP boosts stroke volume while CPAP lowers effective cardiac filling pressure post-CABG.
Why the study?
The cardiopulmonary effects of PEEP and CPAP in spontaneously breathing patients after aortocoronary bypass graft surgery were studied to understand their physiological impact.
Do PEEP and CPAP alter cardiopulmonary hemodynamics in spontaneously breathing post-CABG patients?
Do PEEP and CPAP alter cardiopulmonary hemodynamics in spontaneously breathing post-CABG patients?
p-value: p=<0.001
In spontaneously breathing post-CABG patients, PEEP increases stroke volume and respiratory effort, whereas CPAP decreases effective cardiac filling pressure without changing stroke volume.

May inform ventilatory choices in post-CABG recovery; leaves open effects on clinical outcomes.
STURGEON et al. (1977) studied Post-aortocoronary bypass graft surgery (n=12). PEEP and CPAP vs. Ambient expiratory airway pressure was evaluated on Cardiopulmonary effects (intrapleural pressure, cardiac filling pressure, stroke volume) (p=<0.001). PEEP increased stroke volume (p < 0.001) and respiratory effort, whereas CPAP decreased effective cardiac filling pressure (p < 0.001) in spontaneously breathing post-CABG patients.
