How many seconds after giving rescue breaths should we wait before considering that the casualty is in cardiac arrest?
Traffic accidents
Explanation
To determine if a person is in **cardiac arrest**, it is crucial to assess their breathing. According to first aid steps, we must **check for normal breathing for 10 seconds**. If normal breathing is not detected during this time, it is a sign that the heart may not be functioning properly, indicating a possible cardiac arrest.
- **Normal breathing**: If the person is breathing normally, it means their heart is functioning. In this case, other injuries should be checked, and emergency services should be awaited.
- **Not breathing normally**: If there is no normal breathing in those 10 seconds, **cardiopulmonary resuscitation (CPR)** should be started immediately. This involves performing chest compressions and mouth-to-mouth ventilations to try to restore cardiac and respiratory function until medical help arrives.
Therefore, waiting **10 seconds** after the insufflations is the appropriate time to determine if the person is in cardiac arrest and needs CPR.
