The components of a pulse check in an unresponsive victim include the following key steps:

1. Locating the Correct Pulse Point
   • For adults and children over 1 year old, check the carotid artery located on the side of the neck, between the trachea (windpipe) and the sternocleidomastoid muscle.
   • For infants under 1 year old, check the brachial artery on the inside of the upper arm, between the shoulder and elbow

2. Proper Finger Placement and Technique
   • Use two or three fingers (usually the index and middle fingers) to feel for the pulse.
   • Do not use the thumb, as it has its own pulse that can cause confusion.
   • Apply firm but gentle pressure—enough to feel the pulse without occluding the artery

3. Timing the Pulse Check
   • Check for a pulse for at least 5 seconds but no more than 10 seconds.
   • If no pulse is detected within 10 seconds, assume there is no pulse and begin CPR immediately

4. Simultaneous Assessment of Breathing
   • While checking the pulse, also observe the victim’s chest for breathing movements to assess if they are breathing normally or abnormally

5. Interpreting Results and Taking Action
   • If a pulse is present but the victim is not breathing normally, begin rescue breaths (one breath every 5-6 seconds for adults, every 3-5 seconds for children and infants).
   • If no pulse is detected, start chest compressions immediately and call for emergency help

These steps ensure a quick and accurate assessment of the victim’s circulatory status to guide appropriate life-saving interventions without delay.

Summary: The pulse check involves locating the appropriate artery (carotid for adults/children, brachial for infants), using two fingers to feel gently for a pulse for up to 10 seconds, observing breathing simultaneously, and acting immediately based on the presence or absence of a pulse
