You can take steps at home to help keep your oxygen levels up.

Your treatment team might have given you specific instructions, especially if you were sent home with oxygen. It’s important to follow any instructions you were given by your doctor or respiratory therapist.

Steps you can take on your own include:

  • Stop smoking, if you smoke. Smoking reduces the amount of oxygen circulating in your body.
  • Adjust your sleeping position. It’s best to avoid sleeping flat on your back. Instead, try sleeping on your side. You can also sleep on your stomach with pillows propped under your neck, chest, thighs, and chin.
  • Try pursed-lip breathing. Pursing your lips like you’re about to whistle and breathing deeply is a great way to reduce shortness of breath and increase blood oxygen levels.
  • Adjust how you sit. Try sitting up straight with a pillow behind your back when you’re on a couch or chair to help your lungs get more oxygen.
  • Get plenty of fresh air. Spend time outdoors or keep your windows open to ensure you’re getting fresh air.
  • Go for a walk. Short walks can increase your circulation and blood oxygen level.
