Call 911 anytime you think you may need emergency care. For example, call if:

• You have severe shortness of breath.
• You have symptoms of a heart attack. These may include:
  • Chest pain or pressure, or a strange feeling in the chest.
  • Sweating.
  • Shortness of breath.
  • Nausea or vomiting.
  • Pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly or in one or both shoulders or arms.
  • Light-headedness or sudden weakness.
  • A fast or irregular heartbeat.
  After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.

Call your doctor or nurse advice line now or seek immediate medical care if:

• Your shortness of breath gets worse or you start to wheeze. Wheezing is a high-pitched sound when you breathe.
• You wake up at night out of breath or have to prop your head up on several pillows to breathe.
• You are short of breath after only light activity or while at rest.

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if:

• You do not get better over the next 1 to 2 days.
