Question 1

Oxygen Therapy
Inclusion Criteria (Child)

Answer 1

Significant illness

Significant injury

Question 2

Oxygen Therapy
Inclusion Criteria (Adult)

Answer 2

Critical illness requiring high levels of supplemental oxygen
Serious illness requiring moderate levels of supplemental oxygen if the patient is hypoxaemic
COPD and other conditions requiring controlled or low-dose oxygen therapy
Conditions for which the patient should be monitored but oxygen therapy is not required unless the patient is hypoxaemic.

Question 3

Oxygen Therapy

Exclusion Criteria

Answer 3

Paraquat poisoning (unless < 85%)
Explosive environments

Question 4

Oxygen Therapy

Cautions

Answer 4

Oxygen increases the fire hazard at the scene

Defibrillation of the patient is a spark-hazard, ensure pads are well-fitted and oxygen source removed prior to defibrillation

Care should be taken for patients with a hypoxic drive
COPD should be assumed in a > 50 y/o patient that is a long-term smoker or ex-smoker with a Hx of longstanding breathlessness of minor exertion, in the absence of a Hx of asthma
Aim for 88% - 92% unless critical
