How far past the open chest wound should sealing material be extended?
For an open chest wound, cover the entire wound then seal three sides and leave one corner open. If you seal all four sides and the lungs are punctured, air can build up inside the chest but outside the lung, making it impossible for the patient to breathe.

The ratio of Cardiopulmonary resuscitation chest compressions to breaths is 30.2. Between every 30 chest compressions, deliver 2 rescue breaths. The rescue breath should be approximately 2 seconds between each other. The only difference in adult and child CPR is that with a child, you begin with mouth to mouth before attempting chest compressions. Should the rescue breaths prove to be ineffective in reviving the child, start chest compressions. Chest compressions should be 4-5 centimetres…

Raise the dumbells straight into the air until your arms are fully extended. Bring the weights back down to your chest and repeat.
