What should you do if you feel too tired to perform any more CPR compressions (and your coworker is by your side)?

CPR can be lifesaving in many situations. If you are tired and cannot give more chest compressions you need to make sure that a coworker is by your side. You can then call for a switch. Once you complete your 30 compressions, the coworker will give 2 breaths.

You can then change position, he will now give 30 compressions and you will give 2 breaths. He will continue to give until he is tired and then you can take over for him. This can continue until the person revives, the paramedic arrives or the patient is pronounced dead by a professional.

When you give CPR to an unconscious person whose heart has stopped, you will call for a switch when you feel tired. This is so that you can continue CPR without getting extremely exhausted. When you call for the switch, you will finish your round of thirty compressions. Then, your coworker will give the two breaths (though this step is considered controversial now) and get into position to continue the compressions.

After your coworker gives thirty compressions, you will give two breaths (again, the controversial step). Giving the breaths will give you a chance to let your arms recover. However, be careful about how long you wait. You will get more easily tired after one round of CPR. So will your coworker. If possible, have between two and four people there to help with the rotations. This will give you more time to recover.
