【题目】Basic Steps of CPR Everyone Should Know

Do you know how to offer first aid if a person has an accident and stops breathing but there is no doctor available at hand? Applying CPR is usually helpful when emergencies such as a heart attack occurs. Read this CPR guide now so you know what to do if someone is experiencing a life-threatening (威胁生命) emergency.

Step 1. Position your hands.

Make sure the patient is lying on his back on a firm surface. Kneel beside him and place your hand on the center of the chest. Keep your arms straight, cover the first hand with the other hand and interlock (紧扣) the fingers of both hands together. Keep your fingers raised so they do not touch the patient’s chest.

Step 2. .

Push the breastbone up and down to a depth of about 5 cm about 30 times, at a rate of 100 beats per minute.

Step 3. Give rescue breaths.

Make sure the airway is open, and pinch (捏) the nose so it closes. Gently raise the chin (下巴) upwards with two fingers of your other hand. Take a deep breath, put your mouth over the patient’s, and blow until you can see his chest, rise.Then remove your mouth from the patient’s and look along the chest, watching the chest fall. To get another breath, lift your head and breathe in deeply. Perform Step 3 again.

Step 4. Repeat chest compressions (按压) and rescue breaths.

Repeat the 30 chest compressions followed by the two breaths about five times, and then check for normal breathing. If that person is not breathing normally, continue performing CPR. If breathing restarts as normal, stay with the injured person until help arrives.

First aid is an important life skill that everyone should learn. The more people who learn CPR, the more lives can be saved in the future.
