Resp Failure, Monitoring, Lab Testing

Question 1

What is Respiratory Failure?

Answer 1

Failure to oxygenate (take in O2)

Failure to ventilate (release waste CO2)

Question 2

Type 1 respiratory failure?

Answer 2

Hypoxemia (low O2 in blood)
PaO2 normal: 80-100mmHg
Critical: <60mmHg

Question 3

Type 2 respiratory failure?

Answer 3

Hypercapnia (hypoventilation)

PaCO2 normal: 35-45mmHg
Critical: >50mmHg
*rise in PaCO2 drives pH down

pH normal: 7.35-7.45
Critical: <7.25

RR normal: 12-20
