Episode notes
Skin Reflects Both Flow and Resistance
- Skin characteristics reflect both cardiac output and systemic vascular resistance simultaneously.
- You can't interpret one without considering the other when assessing perfusion.
Cardiac Output and Resistance Interplay
- Cardiac output and vascular resistance are intertwined and influence each other.
- Improving output often involves manipulating resistance as well, not just contractility.
Tailor Hemodynamics Treatment to BP
- When blood pressure is low, don't vasodilate; instead, improve contractility to enhance perfusion.
- When blood pressure is high with peripheral vasoconstriction, start by reducing vascular resistance.
