What to do if…
you develop swelling or rapid weight gain with shortness of breath, especially when lying down

What to do now

1. Call 911 if you are struggling to breathe, cannot speak in full sentences, have chest pain or pressure, fainting, new confusion, blue or gray lips or skin, cough up pink or bloody froth, or have symptoms that are rapidly worsening. Tell the dispatcher about the swelling or rapid weight gain and that breathing is worse when lying down.
2. Sit upright or use the position in which breathing feels easiest. Rest, loosen tight clothing, and avoid physical effort while help is arranged.
3. Follow any emergency action plan already given to you for a diagnosed condition. Use prescribed oxygen, inhalers, or emergency medication only as directed in that plan or by a healthcare professional.
4. If the breathing difficulty is mild and stable and you are not calling 911, contact your doctor, cardiology team, or another healthcare professional now for urgent same-day advice. Seek emergency care if you cannot obtain prompt guidance or your symptoms worsen.
5. Without delaying care, note when the breathlessness and swelling began, where the swelling is, any recent weight change, whether you wake short of breath, and whether you need extra pillows to breathe.
6. Gather your medication list, allergies, recent weight readings, and relevant diagnoses. Tell the medical team if you are pregnant, recently gave birth, started a new medicine, or have a heart, lung, kidney, or liver condition.
7. Ask someone to stay with you if possible. If emergency help is coming, unlock the door, keep your phone nearby, and follow the dispatcher’s instructions.
