| Question | Normal Values |
| Right Arterial Press aka Central Venous Pressure(CVP)(RVEDP) | 0-8 mmHg |
| Right Ventricular Pressure | 15-25 mmHg Systolic 0-8 mmHg Diastolic |
| Pulmonary Artery Pressure | 15-25 mmHg Systolic 8-15 mmHg Diastolic |
| Left Arterial Pressure aka Pulmonary Capillary Wedge Pressure | 4-12 mmHg *Value is same as LVEDP |
| Left Ventricular Pressure | 110-130 mmHg Systolic 4-12 mmHg Diastolic (LVEDP) |
| Mean PA Pressure | 10-20 mmHg *Mean Press=[Sys + 2(Diast)]/3 |
| Systemic Vascular Resistance (SVR) | 900-1500 dynes x sec x cm^-5 *SVR=[MAP-CVP]/CO x 80 |
| Pulmonary Vascular Resistance (PVR) | 25-250 dynes x sec x cm^-5 *PVR=[Mean PAP-PCWP]/CO x 80 |
| Arterial Blood Pressure | 100-140 mmHg Systolic 60-90 mmHg Diastolic |
| Mean Arterial Blood Pressure | 70-100 mmHg *Mean Press=[Sys + 2(Diast)]/3 |
| Cardiac Output | 4-8 lpm *SV x HR = CO |
| Cardiac Index (CI) | 2.5-4 l/min/m² *CI= CO/BSA |
| Heart Rate | 60-100 bpm |
| Stroke Volume | 60-130 ml |
| Ejection Fraction | 50-70% <30% indicate imminent heart failure |
| Mixed Venous Oxygen Saturation (SvO2) | 60-80% |
| Oxygen Content-Aterial (CaO2) | Normal: 20 vol% |
| Oxygen Content-Venous (CvO2) | Normal: 15 vol% |
| Oxygen Extraction C(a-v)O2 | Normal: 5 vol% |
| How is the oxygen content determined? | By adding O2 attached to Hgb (1.34xHgbx%sat) to the amount dissolved in plasma (PO2x0.003) |
| Oxygen Delivery/Transport (Do2) | Normal: 750-1000 ml/min |
| Oxygen Consumption (VO2) | Normal: 250 ml/min |
| Capillary Content of Oxygen (CcO2) | Calculated value based on Hbg and alveolar air |
| Shunt | Normal: <10%; 20-30% considered significant; >30% life threatening |
| Fick Equation | VO2/[C(a-v)O2 x10]=CO also VO2=COx [C(a-v)O2x10] |
