ASTHMA WARNING SIGNS

When Is an Asthma Attack an Emergency?

An asthma attack is an emergency when your quick-relief inhaler doesn’t help or wears off within a few hours, you struggle to speak or walk, your breathing is fast or labored, or your lips or fingertips look blue or gray. Severe attacks can worsen quickly and may become life-threatening without treatment.
Asthma narrows and inflames the airways, making it hard to move air in and out. During a severe attack the airways can tighten enough to limit oxygen, which is why prompt breathing treatments matter.

Signs of a Severe Asthma Attack

Mild symptoms can escalate. Know the warning signs of a serious attack.

Warning signs

If you use a peak flow meter, a reading below half of your personal best is a sign of a severe attack.

What to Do While You Get Help

Take action early and don’t wait for symptoms to peak.
Sit upright, stay as calm as you can, and use your quick-relief inhaler exactly as your doctor or asthma action plan directs. If you aren’t improving, or you aren’t sure what to do, get emergency care.
Bring your inhalers, spacer, and medication list. Tell the care team what you took and when, since that guides your treatment. If symptoms worsen on the way, call 911.

Asthma Attacks in Children

Children can get worse quickly.
In children, watch for fast breathing, grunting, flaring nostrils, skin pulling in at the ribs or neck, a cough that won’t stop, or being too breathless to talk, eat, or play. A child who is struggling to breathe needs emergency care right away.
The Heights Emergency Room treats children and has a patient room dedicated to pediatric patients. See our pediatric ER page.

Common Asthma Triggers

Many things can set off an attack.
Viral infections, pollen, mold, dust mites, pet dander, smoke, strong odors, cold air, exercise, and air pollution are common triggers. Houston’s humidity, mold, and high-ozone days can aggravate symptoms for some people.
A cold or flu can also trigger an attack. See our page on respiratory infections if you also have a fever or a productive cough.
WHEEZING WITHOUT A DIAGNOSIS

Wheezing That May Not Be Asthma

Not every wheeze is asthma, and new breathing trouble should be evaluated.
Wheezing can also come from COPD, pneumonia, heart failure, a blood clot in the lungs, or a severe allergic reaction. If you have never been diagnosed with asthma, or this attack feels different from your usual ones, an emergency evaluation can help find the cause.
Wheezing with hives, swelling of the lips or throat, or sudden trouble breathing after a food, medication, or sting may be anaphylaxis. Use an epinephrine auto-injector if prescribed and call 911. See our allergic reaction ER page.

Oxygen & Monitoring

What Can Trigger a Severe Asthma Attack?

Allergens

Pollen, mold, dust mites, and pet dander.

Respiratory Infections

Smoke, strong fumes, air pollution, and cold air.
