3- Monitoring Part 3

Question 1

Using equipment what 2 things can be measured regarding the respiratory system?

Answer 1

End-tidal carbon dioxide (Adequacy of respiration)
Blood gases - oxygen and CO2

Question 2

Why is it important to consider resp rhythm & efforts as well as rate?

Answer 2

A big difference between 12bpm that is shallow/insufficient vs 12bpm that is deep/ sufficient

Question 3

What does a capnograph measure?

Answer 3

EtCO2
measures CO2 in air that is breathed in and out

Question 4

What are the 3 factors that capnograph can tell us about the body?

Answer 4

Tissue metabolism
Perfusion
Ventilation

A change in ETCO2 values suggests an alteration in one or more of these parameters

Question 5

What is the normal EtCo2 range for dogs & cats?

Answer 5

Dogs = 35-45mmHg
Cats = 28-45mmHg

Question 6

T/F EtCo2 is approx 5mmHg lower than actual blood levels

Answer 6

True

Question 7

T/F Hyperthermia will lead to an decrease in co2 production (Hypocapnia)

Answer 7

False

Hyperthermia leads to an increase co2 production (Hypercapnia)

Question 8

What does arterial blood gas measure?

Answer 8

Levels of arterial oxygen and carbon dioxide- useful for looking at lung function

Question 9

Why is it important to listen to lung sounds

Answer 9

RR does not provide any info on the quality of ventilation or oxygenation

Question 10

What can venous blood gas analysis be useful for

Answer 10

useful for metabolic function
