| Term | Definition |
| Time Constant | Kt= CL x Raw |
| Stroke Volume | SV= C.O./H.R. Normal: 60-130 mL |
| SVR (Systemic Vascular Resistance) | SVR= MAP-CVP/CO X 80 Normal: 800-1500 dynesxsec |
| PVR (Pulmonary Vascular Resistance) | PVR= MEAN PAP-PCWP/CO X 80 Normal: 120-240 |
| Total Oxygen Delivery | Do2= C.O. x (CaO2x10) |
| Oxygen Extraction Ratio | O2 E.R.= CaO2-CvO2/CaO2 |
| Shunt Calculation | CcO2-CaO2/Cco2-CvO2; then multiply by 100 for a % |
| Deadspace | VD/Vt= PaCO2-PECO2/PaCO2 |
| Minute Ventilation | VE= RR X VT |
| A-a gradient | PAO2= FIO2 x (PB-47)-PaCO2/0.8 or PAO2= FIO2 x (PB-47)-PaCO2 if FIO2 greater than 60% don’t use 0.8 or shortcut FIO2 x 7 – CO2; then subtract from given PaO2. |
| Static Compliance | Plat-Peep/VT |
| Dynamic Compliance | Peak-Peep/Vt |
| Resistance | Peak-plat/flow |
| P/F ratio | PaO2/FiO2 |
| Total Cycle Time (I:E RATIO) | Ti-Te= TCT TCT-Ti=Te TCT-Te=Ti |
