TOPIC 9 Flashcards
1
Q
Indications that a patient needs oxygen therapy
A
- SpO2 less than 90%
- PaO2 (oxygen tension) less than 60mmHg
- failure of haemoglobin transportation (tissue hypoxia)
- respiratory distress
2
Q
Children - supplemental O2 considerations
A
- ## humidified, high flow O2 (reduce hypothermia and water loss)
3
Q
Pregnant Women - supplemental O2 considerations
A
- left lateral tilt

A
- high flow
- 2-14L/min
- 24-55%
8
Q
Oxygen methods selected depends on
A
