Respiratory Failure Flashcards
1
Q
Type 1 RF
A
damage to gas exchanging organ (lung) - V/ Q mismatch
The lung is gone
2
Q
causes of Type 1 RF
A
pneumonia, pulmonary oedema, COPD , Bronchia asthma
3
Q
Mx of Type 1 RF
A
Oxygen +/- ventilation
4
Q
Type 2 RF
A
ventilatory failure- inadequate alveolar ventilation to transport oxygen into blood and excrete CO2 ( respi pump failure)
Patient doesn’t breathe
5

A
pulmonary disease- COPD,
cervical cord disease
Diaphragmatic failure
Polio
Myasthenia gravis
GBS
6
Q
Mx of Type 2 RF
A
Ventilation +/- Oxygen
7
Q
PaO2 and PaCO2 levels in Type 1 RF
A
PaO2 reduced
PaCO2 reduced
8
