Care for sudden illnesses by following the same general guidelines as you would for any emergency:
- Do no further harm.
- Check the scene for safety and then check the person.
- First care for life-threatening conditions such as unconsciousness; trouble breathing; no breathing; severe bleeding; severe chest pain; or signs of a stroke, such as weakness, numbness, or trouble with speech.
- Help the person to rest comfortably.
- Keep the person from getting chilled or overheated.
- Reassure the person because he or she may be anxious or frightened.
- Watch for changes in consciousness and breathing.
- If the person is conscious, ask if he or she has any medical conditions or is taking any medication.
- Do not give the person anything to eat or drink unless he or she is fully conscious, is able to swallow, and does not show any signs of a stroke.
- If the person vomits and is unconscious and lying down, position the person on his or her side so that you can clear the mouth.
- If you know the person is having a severe allergic reaction or a diabetic emergency, assist the person with his or her prescribed medication, if asked.
