When an asthma attack starts, sitting upright and using a rescue inhaler right away are the two most important steps. Most mild to moderate attacks can be managed at home if you act quickly and follow a clear sequence. Knowing what to do in advance, and recognizing when home treatment isn’t enough, can prevent a frightening episode from becoming a dangerous one.
First Steps During an Attack
Sit up straight. Lying down compresses your airways, making it harder to breathe. If you’re helping someone else, get them into an upright position immediately. Leaning slightly forward with hands on your knees can also help open the chest.
Grab your rescue inhaler (typically albuterol) and take 2 puffs. Wait about a minute between puffs, and use a spacer if you have one. A spacer is a tube that attaches to the inhaler and holds the medication in a small chamber, giving you more time to inhale it fully. Research shows spacers significantly improve how much medication actually reaches your lungs, even in people with good inhaler technique. During an attack, when your breathing is already strained, that difference matters more than usual.
If those 2 puffs don’t bring relief within 15 to 20 minutes, you can take 2 more. If you find yourself needing albuterol more than 4 times in 24 hours, contact your doctor. That’s a sign your asthma is not under control.
What to Do If Your Inhaler Isn’t Working
For a severe attack where initial puffs aren’t helping, many asthma action plans call for 4 puffs every 15 minutes, repeated up to 3 times, with a spacer. If breathing doesn’t improve after that first round, call for emergency help. Never leave someone having a severe attack alone while waiting.
Signs that the situation is becoming an emergency include:
- Breathing hard and fast with visible rib movement or hunched-over posture
- Difficulty walking or speaking in full sentences
- Nostrils flaring wide with each breath
- Blue or gray lips or fingernails, which signals dangerously low oxygen
- Confusion, agitation, or drowsiness, which can indicate the brain isn’t getting enough oxygen
Any of these signs mean call 911 (or your local emergency number) immediately. Confusion or mental drowsiness in particular signals a critical level of oxygen deprivation that requires urgent medical intervention.
Breathing Techniques That Help
While your rescue inhaler does the heavy lifting, pursed-lip breathing can help you regain control and reduce the sense of panic. Breathe in slowly through your nose, then exhale through pursed lips (as if you’re blowing through a straw) for about twice as long as you inhaled. So if you breathe in for 2 seconds, breathe out for 4.
This works because the gentle backpressure keeps your smaller airways from collapsing during exhalation. During an asthma attack, the airways are already narrowed and inflamed. Pursed-lip breathing creates a small amount of positive pressure that splints them open, reduces the effort of breathing, and helps your lungs exchange oxygen and carbon dioxide more effectively. It won’t replace medication, but it can meaningfully reduce breathlessness while you wait for your inhaler to kick in.
Using Your Peak Flow Meter
If you have a peak flow meter and know your personal best number, it can help you gauge how serious the attack is. Peak flow measures how fast you can push air out of your lungs, and your asthma action plan divides your readings into three zones:
- Green zone (80% to 100% of personal best): airways are open, continue your normal routine
- Yellow zone (50% to 80%): airways are narrowing, use your rescue inhaler and follow your action plan
- Red zone (below 50%): severe obstruction, use your rescue inhaler immediately and call your doctor or emergency services if readings don’t climb back up quickly
A red zone reading is a medical emergency even if you don’t feel as bad as you’d expect. Some people adapt to poor airflow and underestimate how compromised their breathing actually is.
What Happens at the Hospital
If an attack brings you to the emergency room, the medical team will focus on opening your airways and getting your oxygen levels back up. You’ll likely receive the same type of medication as your rescue inhaler but delivered continuously through a nebulizer, which turns liquid medication into a fine mist you breathe in over several minutes. This delivers the drug more consistently and deeply into the lungs than a handheld inhaler can during severe distress.
You’ll also typically receive a course of oral or injected steroids to reduce the inflammation driving the attack. If your oxygen saturation drops below 92%, supplemental oxygen is given until levels stabilize above 94%. In rare cases where these standard treatments aren’t enough, the medical team may use intravenous medications or assisted breathing support.
Hospital admission becomes necessary when someone doesn’t improve with continuous bronchodilator treatment and steroids, when oxygen levels keep dropping despite supplemental oxygen, or when there are signs of exhaustion or altered mental state.
What to Avoid During an Attack
Some common home remedies can actually make things worse. Ingesting camphor-based or mentholated salves, dissolving large numbers of cough lozenges in tea, or taking herbal supplements like echinacea can trigger allergic reactions that worsen airway inflammation. Research from Johns Hopkins found that some asthma patients were unknowingly putting themselves at risk with these approaches.
Other things to avoid: don’t lie flat, don’t try to “push through” exercise, and don’t rely on hot steam or essential oils as substitutes for your rescue inhaler. These approaches waste critical time. The airway narrowing during an asthma attack is a physiological process that requires bronchodilator medication to reverse.
Recovery After an Attack
Once an attack subsides, the risk isn’t over. About 1 in 6 people treated for an asthma attack need hospital care again within two weeks. A follow-up appointment significantly reduces this risk by giving you and your doctor a chance to adjust your treatment plan before another episode hits.
The timeline for that appointment depends on how the attack was managed:
- Treated at home by yourself: request a same-day appointment with your doctor
- Treated by paramedics but not hospitalized: same-day appointment
- Treated in the hospital: appointment within two working days of discharge
At that visit, expect a review of what triggered the attack, whether your current medications are adequate, and whether your asthma action plan needs updating. Beyond this urgent follow-up, an annual asthma review helps catch gradual worsening before it leads to another crisis. If you don’t already have a written asthma action plan with green, yellow, and red zone instructions, that follow-up appointment is the time to create one.
