14 Cards in this Set

  • Front
  • Back
Age group
adults = to and > 16 yo
SpO2 not available/unreliable
initial dose of 2-6 L/min via NC of 5-10 L/min via Hudson until reliable SpO2 reading can be obtained or symptoms resolve
critical illnesses and Mx (10)

-critical ill and haemodynamically unstable

-cardiac arrest/resus

-major trauma/head injury

-CO poisoning


-severe sepsis


-decompression illness

-status epililepticus

-aim for 100%, once haemodynamically stable then titrate

Chronic hypoxaemia condition and Mx


-neuromuscular disorders

-class I, ii, iii obesity

-aim for 100%, once haemodynamically stable then titrate

SPO2 unreliable (9)


-severe asthma

-severe anaemia

-cold extremities

-peripherally shut down

-severe hypotension

-CO poisoning

-severe hypoxaemia

-reading <80%

COPD suspected (5)

Any pt over 40 yo who is


-experiencing dyspnoea that is progressive, persistent and worse with exercise

-has a cough or chronic sputum production

-has family Hx

CO poisoning or pneumothorax O2 Mx
high dose of O2 until arrival at hospital +- breathlessness of hypoxaemia
Other poisonings O2 Mx (2)

-maintain SpO2 of 94-98%

- paraquat and bleomycin SpO288-92%

Other considerations when giving O2 (7)

-Ax VT to ensure adequate ventilation

-O2 exchange at its greatest in the upright position unless other clinical problems determine otherwise

-clean fingers/ nail polish/ nail infections

-O2 not required in anxiety/panic/ hypoventilation no CO2 retention (ie paper bag)

-women >20/52 pregnant use left lateral tilt

-masks not used with <5L/min

-NC effective with mouth breather except where nasal passages are blocked or congested

Evidence of hypoxaemia/breathlessness - Ax for? (4)

-acute or chronic

-respiratory status

-AX and monitor SpO2 continuously

-consider causes of hypoaemia

Adequate SpO2 def and Mx

-= to and > 94%

-no O2 required, reassure pt

Mild-moderate hypoxaemia def and Mx

-SpO2 85-93%

-titrate O2 flow to spO2 of 94-98%

-initial dose 2-6L/min via NC

-consider Hudson 5-10L/min

Moderate-severe hypoxaemia or critical illness def and Mx

-SpO2 <85%/arrest/resus/major trauma/head injury/CO poisoning/shock/severe sepsis/anaphylaxis/decompression illness/status epilepticus

-NRB 10-15L/min

-inad VT - BVM vent with 100% O2

-stable - titrate O2 to SpO2 of 94-98%

-deteriorates or SpO2 remains <85%- BVM vent with 100% o2 -consider LMA ETT CPG

Chronic hypoxaemia def and Mx

-COPD/neuromuscular disorders/obesity

-at risk of hypercapnic resp failure

-titrate O2 to SpO2 88-92%

-no critical illness-2-6L/min NC-consider Hudson 5-10L/min

-pt deteriorates or SpO2 <85%- as per mod/severe hypoxaemia
