| Question | Answer |
| Pack years= | # of packs/day x # of years smoked. |
| MAP= | (2x diastolic pressure) + Systolic

| Fic equation:
Cardiac output/QT= | V02
___________________________________
C(a-v)o2 (10) |
| Cardiac output=
QT | HR x SV |
| Stroke volume = | QT
__________________________________
HR |
| SVR= | (MAP-CVP)
_____________________ x 80
QT |
| PVR= | MPAP-PWP
_____________________ x 80
QT |
| Ca02 | (Hbg x 1.34 x Sa02) + (Pa02 x 0.003)
Oxygen in RBC 02 in plasma |
| Cvo2= | (Hbg x 1.34 x Svo2) + (Pvo2 x 0.003) |
| Vo2= | QT x C(a-v)02 x 10 |
| QS/QT | cco2-Cao2
_____________________
cco2-cvo2 |
| Desired Pao2 | Current Fio2 x Desired Pao2
_______________________________
Current pao2 |
| P/F ratio | Pao2/fio2 |
| Pediatric drug dosage
ESD= | wt (lbs) x normal adult dose
_____________________________
150 |
| Amount of drug in mg. | Drug% x 10 x mL= number of mg in 1mL of the drug. |
| Minute ventilation= | Vt x F |
| Dynamic Compliance= | Exhaled volume
__________________________
peak insp pressure - peep |
| Static Compliance= | Exhaled volume
__________________________
Plateau pressure - peep |
| Raw= | Peak pressure-Plateau pressure |
| IDBW for Males= | 106lbs + 6lbs/inch over 5ft |
| IDBW for Females= | 105 lbs + 5lbs/inch over 5ft |
| Calculating minimal flow rate= | (Vt x rate) x ( I+E) |
| RSBI= | RR/VT= |
| Duration of flow in tank | gauge pressure (psi) x tank factor
__________________________________
liter flow |
| Tank factor for E tank | .28/ L psi (0.3) |
| Tank factor for H tank | 3.14 L psi (3.0) |
| Total flow= | factor of tank used x liter flow |
| Calculating patients max heart rate. | 220- HR |
| calculating volume lost through chest tube | Vt-Vte= Lost Vt |
