At an incident, a casualty is unconscious. You need to check whether they’re breathing. How long should you allow for this check?

Explanation: Once the casualty's airway is open, listen and feel for breath. Do this by placing your cheek over their mouth and nose, and look to see if their chest rises. This should be done for up to 10 seconds. If you cannot detect any breathing, you should begin compressions.
