<s>[INST] Can I Take Flights? [/INST] If your heart failure symptoms are stable, you probably won’t have any problems. Some people do require extra oxygen during the flight. If so, check ahead with your airline so that you can understand their policies.

Also, if you’ve had a pacemaker implanted, let the airport staff know when you enter the security checkpoints (but neither air travel nor security machines will affect your device). To stay comfortable, try stretching and moving about while on the plane. Your doctor may also advise that you wear compression socks to prevent blood clots.

Talk to your doctor if you’re thinking about traveling to high altitudes. The lack of oxygen can put more strain on your heart. Your medications may need to be adjusted or it may be safest not to go.
