Study Summary
This study will investigate the different tidal volume (Vt) strategies during a cardiac catheterization procedure to determine whether or not low or high Vt have an impact on cardiac output. Research question: While maintaining the same minute ventilation/PaCO2, does higher Vt (10 cc/kg)/lower rate vs. lower Vt (6 cc/kg)/higher rate (maintaining consistent PEEP) result in improved cardiac output?
Primary Outcome
The investigators will assess cardiac output using the Fink principle for each arm of randomization.
Interventions
- PROCEDURE Low Vt protocol
- PROCEDURE High Vt protocol
