Basic Life Support

1. You are likely to be presented with a resus mannequin and told that you have found the patient collapsed either on a corridor in the hospital or somewhere outside. Either way the algorithm is fairly similar.

2. The basic way of thinking is: Danger, Response, Airway, Breathing and Circulation.

3. Initially you should assess if there is any danger in the situation either for you or for the patient.

4. You should check if there is any response from the patient. This is performed by gently shaking the patient’s shoulders and loudly shouting into both ears asking them ‘Can you hear me?’ If there is no response you should shout for help.

      Check for response

5. Check if the patient’s airway is patent. Perform the head tilt (unless there is any chance of cervical spine injury) and jaw thrust to open the airway. Ensure that there is no physical blockage by their tongue, vomit or anything else.

      Check patient's airway

6. Check the patient’s breathing and circulation simultaneously. This is performed by maintaining the head tilt and jaw thrust, placing your face and ear over the mouth to feel for any respiratory effort whilst observing the chest for any movement. At the same time you should place two fingers over the carotid pulse to assess circulation.

7. If breathing and circulation are normal, place the patient in the recovery position and find help.

8. If breathing and/or circulation are absent you should call 999 (UK) or the crash call number in your hospital (commonly 2222).

9. Once you have called for support, you should start chest compressions. Place one hand over the sternum roughly in the middle, interlock your fingers and lock your elbows positioning yourself vertically above your hands. Depress the sternum 4-5 centimeters and release the pressure. Repeat this 30 times at a rate of 100 per minute.

      Start chest compressions

10. You should start to give a combination of 2 rescue breaths and 30 chest compressions. For the rescue breaths ensure the head tilt and jaw thrust are in place, pinch the soft part of the nose so that it is closed, open the mouth, seal your lips around theirs and blow steadily for 2 seconds. Watch the chest to check that it rises and falls with the breath. Once the breaths are given return to giving 30 chest compressions.

       Pinch nose and tilt head
    2. 

       Breathe into patient

11. If there is anyone else around you should share out the work with one of you performing the breaths and one the compressions swapping when tired.

12. You should continue this cycle of 2 rescue breaths and 30 chest compressions until either further help arrives, the patient regains consciousness or you can no longer physically continue.
