Brief summary
Performing chest compressions for patients in cardiac arrest is tiring, and as rescuers become more tired their performance has been shown to deteriorate. Quality of Cardiopulmonary Resuscitation (CPR), especially chest compressions, is adversely affected by fatigue and is one of the few factors shown to be independently associated with the likelihood of a person surviving a cardiac arrest. The administration of supplemental low flow oxygen to a rescuer via nasal cannula may slow their fatigue, and increase the length of time that that the rescuer is able to provide good quality chest compressions. We intend to undertake a study to assess the effectiveness of supplemental low flow oxygen on healthy, volunteer rescuers in improving their quality and length of performance of chest compressions on a resuscitation manikin.
Interventions
Participants will each perform three periods of 10 minutes of External Cardiac Compressions (ECC), swapping with their partner (research assistant) every 2 minutes as recommended by the Australian Resuscitation Council.
Each participant will perform on a resuscitation practice manikin:
1. ECC with room air (control: ECC-RA)
2. ECC with air via Nasal Cannula (NC) at 4 litres per minute (inspired oxygen fraction 21%)(intervention 1: ECC-A)
3. ECC with oxygen via NC at 4 litres per minute (estim

ECC with oxygen via NC at 4 litres per minute (estimated inspired oxygen fraction 36%)(intervention 2: ECC-O) The NC will be administered administered continuously for the full 10 minutes of CPR. A washout period of 20 minutes will be performed between each arm.
