Using a paper bag to control hyperventilation

Try these steps to control hyperventilation

• Take 6 to 12 easy, natural breaths, with a small paper bag held over your mouth and nose. Then remove the bag from your nose and mouth and take easy, natural breaths.
• Next, try belly-breathing (diaphragmatic breathing).
• Alternate these techniques until your hyperventilation stops.

If hyperventilation continues for longer than 30 minutes, call your health professional immediately.

Do not try this technique if:

• You have any heart or lung problems, such as coronary artery disease, asthma, chronic obstructive pulmonary disease (COPD, emphysema), or a history of deep vein thrombosis, stroke, or pulmonary embolism.
• Rapid breathing occurs at a high altitude [above 6000 ft (1829 m)]. Breathing faster than normal is a natural response to an increased altitude.

Follow these precautions when using this technique:

• Do not use a plastic bag.
• Do not breathe continuously into a paper bag. Take 6 to 12 natural breaths, with a paper bag held over your mouth and nose, then remove the bag from your nose and mouth.
• Do not hold the bag for the person who is hyperventilating. Allow the person to hold the bag over his or her own mouth and nose.
