Some Equations...
• MAP = 1/3 SBP + 2/3DBP• CO = SV x HR• CI = CO/BSA• SVR = (MAP-CVP)/CO x 80• PVR = (MPAP - PAOP)/CO x 80• LVSWI = SVI x (MPAP-PAOP)/BSA x

Normal Values
• Cardiac Output (CO) : 4 -8 L/min• Cardiac Index (CI) : 2.4 - 4.0 L/min/m2• MAP : 70-105 mm Hg• Systemic Vascular Resistance (SVR):
800 - 1200 dynes/sec/cm5• Pulmonary Vascular Resistance (PVR):
<250 dynes/sec/cm5 • Stroke Volume (SV): 60-100 ml/beat

1. Why is this patient hypotensive?
2. Why is this patient in shock?
3. Why is this patient in pulmonary edema?
4. How can I minimize fluid infusion while maintaining perfusion in my hypoxic patient?
4. Will this patient tolerate empiric resuscitation and diagnosis through therapeutic challenge?
