Anesthetic Monitoring

Question 1

What 4 parameters do we monitor during surgery?

Answer 1

Heart (rate, rhythm, ECG, PaO2)

Arterial BP

Respiration (rate, depth, effort)

ETCO2

Question 2

T/F: a normal ECG confirms normal CO

Answer 2

FALSE

*heart can have pulseless electrical activity

Question 3

For adequate tissue perfusion, the following parameters must be at least:

1) Systolic pressure
2) mean arterial pressure

Answer 3

1) >80mmHg

2) >60mmHg

Question 4

Which BP parameters (SAP, DAP, MAP) are measured by:

1) Oscillometric
2) Doppler
3) Sphygomanometer

Answer 4

1) SAP, DAP, MAP
2) SAP
3) SAP, DAP

Question 5

Which drug, used for treatment of hypotension, increases contractility but does NOT cause vasoconstriction?

Answer 5

Dobutamine

*No increases in afterload

Question 6

What does the pulse oximeter measure?

Answer 6

oxygen saturation

Question 7

When SaO2 is 90% what is PaO2 estimated to be?

Answer 7

~60mmHg

Question 8

How can use estimate PaCO2 using ETCO2 in:

1) small animals
2) large animals

Answer 8

1) add 1-5mmHg to ETCO2

2) add 5-10mmHg to ETCO2
