Asthma attacks rarely happen without warning. Before one begins, you might:
Signs of an asthma attack can change from one attack to the next. One time you might have little or no coughing beforehand. The next time, you might have a cough that you just can't get rid of, especially at night.
An asthma cough is usually dry and hacking. If you have one that doesn't go away after other cold symptoms are gone, that could point to asthma.
Avoid taking cough medicine to feel better. It won't help the asthma.
A peak flow meter can let you know if an attack is about to happen. Be sure you always know the number that reflects your best breathing.
- If your peak flow meter shows numbers between 50% and 80% of your personal best, an asthma attack has probably started.
- A number below 50% means an emergency. Use your rescue inhaler, and call for help right away.
- Call 911 if you have trouble walking or talking because you're short of breath, or if your lips are blue or gray. Use your rescue inhaler while you wait for help.
An action plan tells you how to deal with the symptoms of an asthma attack.
- Based on your peak flow numbers, it shows you what medicines to take and when. It's important to follow the steps and take your medications exactly as your doctor tells you to.
- If your symptoms still get worse after you've followed your plan, call your asthma doctor. Your plan should have instructions for emergencies, too.
During an asthma attack, muscles around the airways tighten, and the airway linings swell.
- The airways make too much mucus, which can block the air tubes in the lungs.
- Air gets trapped in the lungs, and it gets hard to breathe.
Wheezing might be the first symptom you notice. But as the attack gets worse, you'll feel more chest tightness and shortness of breath. Eventually, you might feel like you can't get enough air.
When someone is having trouble breathing, he might lean forward, speak in single words instead of sentences, and get very agitated.
As the problem gets worse, he might hunch over with his hands supporting his upper body. This is called the tripod position.
When it's hard to breathe, the tissue in the chest and neck may sink in with each breath. This is called retraction.
Retractions mean not enough air is getting into the lungs. They're a sign of a medical emergency. Call 911 or see a doctor right away.
In children, other signs that breathing is getting worse are:
- Poor appetite
- Feeling tired
- Not as active as usual
Blue or gray lips or fingernails are a sign that there's not enough oxygen in your blood. The condition is called cyanosis.
If it happens, you need medical help right away. Call 911 as soon as possible.
Get emergency help at once if you have any of these symptoms:
- Trouble talking
- Can't exhale or inhale
- Shortness of breath
- Feelings of anxiety or panic
- Coughing that won't stop
- Pale, sweaty face
