First Aid for Heart Attack
1. Encourage patient to rest
At the onset of symptoms, encourage the patient to stop any physical activity and lie down to rest.
2. Prescribed medication
If the patient takes any prescribed medication for angina, assist them in taking it as directed by their doctor.
3. Call for medical attention
Do not attempt to move patient to medical care – they may suffer cardiac arrest. Call for an ambulance instead.
If there is no improvement in symptoms after ten minutes, give the patient 300mg or one tablet of aspirin with water, unless the patient is allergic to it. Aspirin thins the blood, and can assist with circulation.
5. Monitor Lifeline
Do not leave the patient unattended. Follow DRABC and be prepared to give CPR if the patient loses consciousness. Continue to monitor the patient’s lifeline – Follow DRABC.
