Ensure environmental safety, protect yourself and avoid secondary harm

Determine patient consciousness

chest compressions

Open airway (clear oral secretions, etc.)

artificial respiration

early defibrillation

Visible eye movement, eyelash reflex to light reflex appears

Cyanosis turns to ruddy

The pulse still exists after the compression is stopped, indicating that the heartbeat is restored.

From large to small, reaction to light appears at the same time (from small to large, fixed, indicating invalid)

Have strong spontaneous breathing (weak, still need to insist on artificial assisted breathing)

Multiple pressers are replaced every 2 minutes

Substitution time is completed within 5 seconds

The blowing time is long and the air flow speed should be slow

If it has happened, gently press the upper abdomen with your hands to help the gas escape.

If there is reflux and vomiting, tilt the patient's head to one side to prevent aspiration, and a gastric tube can also be placed

Restore effective self-help circulation and spontaneous breathing

A more professional life support rescue team will take over

Doctor confirmed death

If the rescuer continues to resuscitate, he will be in danger or put other people in danger.
