is to act fast.
1. Call an ambulance, and let the ambulance call centre person know that you suspect the victim has had a stroke.
2. If the person is conscious, lie them down with their head and shoulders supported (use pillows or cushions). This lowers blood pressure in the brain.
3. Lie the person on his or her side so that saliva can drain from the mouth. Loosen any tight clothing.
4. Assure the person that help is on the way. Do NOT give him/her anything to eat or drink.
5. If the person becomes unconscious, put them in the recovery position — to prevent anything (blood, saliva, or their tongue) from blocking the windpipe and choking them. To do this, carefully roll the person onto his/her stomach, with the arm and leg on one side straight beside their body, and the other arm and leg bent to prop up the upper and lower body. Tilt the person's chin back to straighten the throat.
Above all, if the person is conscious, be as reassuring as possible and try to keep the patient calm. Don't let other people crowd around.
