What 4 parameters do we monitor during surgery?
Heart (rate, rhythm, ECG, PaO2)
Arterial BP
Respiration (rate, depth, effort)
ETCO2
T/F: a normal ECG confirms normal CO
FALSE
*heart can have pulseless electrical activity
For adequate tissue perfusion, the following parameters must be at least:
1) Systolic pressure
2) mean arterial pressure
1) >80mmHg
2) >60mmHg
Which BP parameters (SAP, DAP, MAP) are measured by:
1) Oscillometric
2) Doppler
3) Sphygomanometer
1) SAP, DAP, MAP
2) SAP
3) SAP, DAP
Which drug, used for treatment of hypotension, increases contractility but does NOT cause vasoconstriction?
Dobutamine
*No increases in afterload
What does the pulse oximeter measure?
oxygen saturation
When SaO2 is 90% what is PaO2 estimated to be?
~60mmHg
How can use estimate PaCO2 using ETCO2 in:
1) small animals
2) large animals
1) add 1-5mmHg to ETCO2
2) add 5-10mmHg to ETCO2
