I am the only rescuer And I have an unresponsive breathless adult , I will start chest compression for 2 minutes then I will call for help

In high quality CPR, Chest compression rate per minute is less than 120

In high quality CPR in adults, the depth of chest compression is 1/3 the depth of the patient chest

In this ECG , you should give 200 j asynchronised shock immediately

the best site to check pulse in infants is the brachial artery

In case of choked unconscious patient , CPR chould be initiated immediately

In case of unresponsive breathless child , you should start CPR before you call for help

You can use an AED pediatric Pads with adult Patient

in case of a child, manual defibrillator is better than AED

The first step to take with a collapsed patient is to check pulse
