Answer 5

rCBF = 20-150 mL/min/100g

Question 6

List 4 factors that allow for a fast induction.

Answer 6

low blood gas coefficient, low cardiac output, high ventilation, high inhaled concentration

Question 7

Anything that increases sympathetic tone will require increased MAC. Give an example of something that increases sympathetic tone.

Answer 7

pain increases sympathetic tone

Question 8

At what MAC does only 1% of ppl respond to surgical incision?

Answer 8

1.3 MAC - if you want to reasonably anesthetize a person, use 1.3 MAC

Question 9

Why can you decrease the MAC of gas when using N2O with a volatile anesthetic?

Answer 9

N2O provides analgesia

Question 10

Blood pressure depends on what 3 things?

Answer 10

Volume, Resistance, and Cardiac Output

Question 11

Any volatile with the -CF2H group used with a dry absorber has the potential to produce what?

Answer 11

Carbon Monoxide

Question 12

What is pulsus paradoxus?

Answer 12

In medicine, a pulsus paradoxus (PP), also paradoxic pulse or paradoxical pulse, is defined as an abnormally large decrease in systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mmHg or 10 torr. When the drop is more than 10mm Hg, it is referred to as pulsus paradoxus.

Pulsus paradoxus has nothing to do with pulse rate or heart rate. The normal variation of blood pressure during breathing/respiration is a decline in blood pressure during inhalation and an increase during exhalation.

Question 13

Pulsus paradoxus is a sign that is indicative of what conditions?

Answer 13

Pulsus paradoxus is a sign that is indicative of several conditions, including cardiac tamponade, pericarditis, chronic sleep apnea, croup, and obstructive lung disease (e.g. asthma, COPD).
