Basic Life Support

Aloha amigos,

We have a splendid moment this week ! GMt103- First Aid week was really awesome. One of the highlights of this week is Practical 1 – Basic Life Support. We are trained to help people immediately when someone is unconscious, not breathing and suspected to have a cardiac arrest.


When someone collapse in front of you, this is what you should do : DRSCAB !



S-Shout for help




The first step is D- to make sure there is no danger around the casualty. If they are drowning, drag them to the land. If they are in the middle of the road, lift them to the side walk. If they are crowded with people , tell everyone to give some space to the casualty. Don’t forget to introduce yourself and tell people what you are about to do.

Secondly is R – get a response from the casualty.

“Sir, are you okay? are you okay?” if they are not responding, proceed to the next step.

Thirdly, S. Shout for help. Ask anyone around you to call emergency number (999) immediately. And, ask for AED. ( automated external defribilator). Check the casualty’s pulse in less than 10 seconds. If there is pulse, casualty is okay and you just have to wait for help to come.

If no pulse can be feel or you are unsure whether there is pulse or not, just proceed to cardiopulmonary resuscitation. So now, we are left with C , A and B.

C – circulation, A- airway and B -breathing. Do a chest compression and a mouth to mouth resuscitation with a ratio of 30:2.

How do you do a chest compression?


locate the jugular notch and the end of the sternum ( xiphoid process) . Divide the sternum into two and put your hands on the lower part of right side of the patient. (From our view its the right side- heart is on the left ) . Put your dominant hand on top of your other hand and lock it. Make a tight grip. Straighten your arm and use your body weight to compress not the arm. This is CPR not a push ups routine.

A good chest compression is when you allowed the chest to recoil after every compress. The depth of each compression would be best around 5cm to 6 cm but in paediatric patients around 4cm to 5cm. Minimize interruption while doing CPR and in a rate around 100-120 per minute.

Do this for 5 cycle ( 30 chest compression and 2 mouth-to-mouth per cycle) and check the casualty’s pulse. If pulse and breathing are normal, lift the casualty to lie in a lateral position. Lie on his left.

If the casualty have pulse but no regular breathing, proceed to mouth to mouth resuscitation every 6 seconds continuosly for 2 minutes.

You should only stop basic life support when the casualty shows sign of life. For example, they are conscious and are able to hold and talk. Or when you are extremely tired to do a CPR then you can stop. Or when help has arrive.

Well, that’s my summary for practical basic life support. It was FUN indeed. Thank you Dr Jack !

For our second practical we did Bandage and Bleeding Control , meanwhile for the third practical we did Immobilization technique. Nothing extra ordinary because some of us have already learn this during school.

I guess that’s all for this post. I’ve more to update but I’m quite busy lately so I’ll find some time later and post here okay? Next post will be about MSFT and kayak camp ! Yeay

Till we meet again. Thank you.
