Episode notes
Principles of Post-Op Cardiac Care
- Support the post-op heart by improving contractility, normalizing preload, and optimizing afterload.
- Adequate monitoring is key to managing these changes effectively.
Essential ICU Monitoring Tools
- Monitor post-op cardiac patients with ECG, pulse oximetry, invasive BP, central lines, and possibly pulmonary artery catheters.
- Track temperature and fluid balance closely during the immediate post-op period.
Understanding Cardiac Index
- Cardiac index is crucial and should be kept above 2 to avoid systemic hypoperfusion.
- Cardiac output equals heart rate times stroke volume; cardiac index adjusts for body surface area.
