Hyperventilation: First Aid for Rapid Breathing, Panic and Tingling

Hyperventilation means breathing faster or deeper than the body needs, which blows off too much carbon dioxide. It is often triggered by anxiety, panic or emotional distress, and it feels alarming: the person may feel they cannot get enough air, even though the problem is that they are breathing too much. Good hyperventilation first aid is calm, practical and cautious, because rapid breathing can also be the first sign of a serious medical problem that must not be missed.

Signs and Symptoms of Hyperventilation

• Rapid, often shallow breathing and a feeling of suffocation
• Anxiety, a sense of panic or loss of control
• Tingling or pins and needles around the mouth, hands and feet
• Cramping or spasm of the fingers and toes in prolonged episodes
• Light-headedness, chest tightness and a pounding heartbeat
• Normal pink skin colour, which helps distinguish it from conditions where the lips turn blue

The tingling and spasm happen because blood carbon dioxide has dropped, not because the person has too much oxygen.

Rule Out Serious Causes First

Do not assume hyperventilation is anxiety. Rapid breathing can accompany asthma, a chest infection, a collapsed lung, a heart attack, a pulmonary embolism, severe bleeding, diabetic emergencies, poisoning, overdose and altitude illness. Treat it as an emergency and call for help if the person:

• Has chest pain or pressure, especially with sweating or pain spreading to the arm or jaw
• Has a history of heart or lung disease, or asthma
• Has blue lips, a pale clammy appearance or is becoming drowsy or confused
• Has a fever, has been injured or has just been exposed to smoke, fumes or chemicals
• Is not improving after ten to fifteen minutes of calm coaching

For people with asthma, follow the steps in our asthma attack guide rather than treating breathlessness as panic.

Hyperventilation First Aid: 6 Steps

1. Stay calm and speak gently. A steady, friendly voice does more than any technique. Tell the person that you are staying with them and that this will pass.
2. Move them somewhere quiet. Take them away from crowds, friends and relatives who may be anxious too, or ask bystanders to give space.
3. Sit them comfortably. Upright and supported is best.
4. Coach slow breathing. Ask them to breathe in gently through the nose for about four seconds and out slowly through pursed lips for about six seconds, focusing on the length of the breath out. Breathe with them so they can match your rhythm.
5. Check for injuries or other causes. Look for any sign of bleeding, bites, stings or pain, and ask what happened beforehand.
6. Stay until they recover. Do not leave the person alone. Symptoms usually settle within ten to twenty minutes once breathing slows.

Should You Use a Paper Bag?

Breathing into a paper bag was once widely taught, and some older manuals still describe it. It is no longer recommended. Rebreathing can lower blood oxygen, which is dangerous if the rapid breathing is actually caused by asthma, a heart problem or another medical condition. Slow, coached breathing is safer and works just as well in genuine cases of panic-related hyperventilation.

When to Seek Medical Advice

If the symptoms settle quickly, there are no injuries and the person has recovered completely, further medical attention may not be necessary. However, recurring episodes, episodes without an obvious trigger, or episodes that come with other symptoms deserve a medical review. A doctor can look for physical causes and discuss support for anxiety or panic where relevant.

Frequently Asked Questions

Can hyperventilation make you faint?
Yes. Low carbon dioxide narrows blood vessels to the brain, which can cause dizziness and sometimes fainting. See our guide to fainting first aid.

How long does a hyperventilation episode last?
Most settle within about ten to twenty minutes once breathing slows, although the person may feel tired or shaky afterwards.

Is hyperventilation dangerous?
The episode itself is rarely harmful, but the symptoms overlap with serious conditions, so check for warning signs before assuming it is only anxiety.
