Emergency warning signs

Carefully monitor yourself or your loved one for worsening symptoms. If symptoms appear to be getting worse, call the doctor.

The doctor might recommend use of a home pulse oximeter, especially if the ill person has risk factors for severe illness with COVID-19 and COVID-19 symptoms. A pulse oximeter is a plastic clip that attaches to a finger. The device can help check breathing by measuring how much oxygen is in the blood. A reading of less than 92% might increase the need for hospitalization. If the doctor recommends a pulse oximeter, make sure you understand how to use the device properly and when a reading should prompt a call to the doctor.

If you or the person with COVID-19 experiences emergency warning signs, medical attention is needed immediately. Call 911 or your local emergency number if the sick person can't be woken up or you notice any emergency signs, including:

• Trouble breathing
• Persistent chest pain or pressure
• New confusion
• Bluish lips or face
• Inability to stay awake
• Pale, gray or blue-colored skin, lips or nail beds — depending on skin tone
