Compression-only CPR

an alternative to mouth to mouth

COMPRESSION-only CPR may be performed as a suitable alternative to the technique outlined in stages 1-5, elsewhere on this page. When chest compressions are performed, air is evacuated from the lungs. When the chest recoils air is drawn in, creating a type of panting effect. This will turn over sufficient fresh air to maintain oxygenation of the heart muscle and brain. It is particularly effective in situations where rescue breaths cannot be delivered to the patient (eg, extensive facial injuries), or if the rescuer considers there is risk involved in delivering breaths.

Method

PERFORM steps 1-4 as outlined above; continuous chest compressions, pressing down to a minimum depth of 5cm.

Compressions must be hard and fast: aim for a rate of between 100 and 120 compressions per minute.

This compression speed must be the same for all victims; however, the hand positioning and depth of compressions differs for infant, child and adult.

Continue compressions until the AED and/or emergency services arrive or the patient recovers.

If a second rescuer is available, ensure rotation every two minutes to reduce risk of fatigue.
