   - Call the person's name loud to check if they are conscious.
   - If no response, move your ear close to the mouth and nose to see if the person breathes.
-  - If no breathing call 112 (or ask another person to do so).
+  - If no breathing call 112 (or ask another person to do so) set the phone on handsfree mode. Report the incident and listen to the operator for support.
-  - If there is a defibrilator close by fetch it (if possible send another person to get it). Closest one to ETA is on the 5th floor close to the stair case.

+  - Place person with the chest up.
+  - CPR: Put both hands one on top of the other on the chest where the center of the imaginary line between both nipples would be. Keep arms stiff and press hard using your body weight. Hands should sink 5 to 6 cm. Remember, a broken rib is better than a dead person. Repeat 30 times in around 15 seconds.
+  - Put your mouth against the other persons mouth, close their nose with a hand and pull their chin down with the other. Give two mouthfuls of air, ensuring the chest of the person rises and holding air for at least a second.
+  - Repeat the CPR procedure until the defibrillator arrives.
+  - When defibrillator arrives press the button to start it.
+  - Place the pads on the chest close to the right shoulder and the other pad on the tummy close to the left elbow.
+  - Follow the instructions, ensure nobody touches the patient before the defibrillator activates. Remember that you might need to press the button defibrillation.
+  - Resume CPR until the defibrillator instructs you to stop doing so.
+The ideal ratio is 30 presses followed by 2 breathes. Presses should be 100 to 120 times per minute.
+CPR is a very tiresome process, if there is more than one person it might be a good idea to take turns between presses and blows.
+Prioritize calling 112 and others close by for help, then getting a defibrillator (if it will take you less than 4 minutes to get it) and then CPR. CPR wins time but does not restart the heart.
+CPR is painful if the person is conscious. If unsure perform CPR and stop if the person complains.
+=====Calling 112=====
+As when answering to an emergency situation, it is important to answer the following questions when calling 112.
+Where? Where is help needed? (Position) Try to give as clear indications as possible
+What? What has happened?
+Who? Who is it distressed? Number of people (if many) and age.
+How? Does the distressed person need help? (ambulance/medicine/fire brigade/police/sea rescue?).
+When? How long ago did the issue happen.
