Most people take breathing for granted. People with certain illnesses may have breathing problems that they deal with on a regular basis.

This article discusses first aid for someone who is having unexpected or sudden breathing problems.

Breathing difficulties can range from:

• Being short of breath
• Being unable to take a deep breath and gasping for air
• Feeling like you are not getting enough air

Difficulty breathing - first aid; Dyspnea - first aid; Shortness of breath - first aid

Breathing difficulty is often a medical emergency. An exception is feeling slightly winded from normal activity, such as exercise.

There are many different causes for breathing problems. Common causes include some health conditions and sudden medical emergencies.

Some health conditions that may cause breathing problems are:

• Anemia (low red blood cell count)
• Asthma
• Chronic obstructive pulmonary disease (COPD), sometimes called emphysema or chronic bronchitis
• Heart disease or heart failure
• Lung cancer, or cancer that has spread to the lungs
• Respiratory infections, including pneumonia, acute bronchitis, whooping cough, croup, and others
• Conditions which restrict the movement of the chest wall or diaphragm
• Certain neurologic conditions

Some medical emergencies that can cause breathing problems are:

• Blood clot in the lung
• Collapsed lung (pneumothorax)
• Heart attack
• High altitude pulmonary edema (HAPE)
• Injury to the neck, chest wall, or lungs
• Pericardial effusion (fluid surrounding the heart that can stop it from filling properly with blood)
• Pleural effusion (fluid surrounding the lungs that can compress them)
• Life-threatening allergic reaction
• Near drowning, which causes fluid buildup in the lungs

People having breathing difficulty will often look uncomfortable. They may be:

• Breathing rapidly
• Unable to breathe lying down and need to sit up to breathe
• Very anxious and agitated
• Sleepy or confused

They might have other symptoms, including:

• Dizziness or lightheadedness
• Pain
• Fever
• Cough
• Nausea
• Vomiting
• Bluish lips, fingers, and fingernails
• Chest moving in an unusual way
• Gurgling, wheezing, or making whistling sounds
• Muffled voice or difficulty speaking
• Coughing up blood
• Rapid or irregular heartbeat
• Sweating

If an allergy is causing the breathing problem, they might have a rash or swelling of the face, tongue, or throat.

If an injury is causing breathing difficulty, they might be bleeding or have a visible wound.

If someone is having breathing difficulty, call 911 or your local emergency number right away, then:

• Check the person's airway, breathing, and pulse. If necessary, begin CPR.
• Loosen any tight clothing.
• Help the person use any prescribed medicine (such as an asthma inhaler or home oxygen).
• Continue to monitor the person's breathing and pulse until medical help arrives. DO NOT assume that the person's condition is improving if you can no longer hear abnormal breath sounds, such as wheezing.
• If there are open wounds in the neck or chest, they must be closed immediately, especially if air bubbles appear in the wound. Bandage such wounds at once.
• A "sucking" chest wound allows air to enter the person's chest cavity with each breath. This can cause a collapsed lung. Bandage the wound with plastic wrap, a plastic bag, or gauze pads covered with petroleum jelly, sealing it on three sides, leaving one side unsealed. This creates a valve to prevent air from entering the chest through the wound, while allowing trapped air to escape from the chest through the unsealed side.

DO NOT:

• Give the person food or drink.
• Move the person if there has been a head, neck, chest or airway injury, unless it is absolutely necessary. Protect and stabilize the neck if the person must be moved.
• Place a pillow under the person's head. This can close the airway.
• Wait to see if the person's condition improves before getting medical help. Get help immediately.

Call 911 or your local emergency number if you or someone else has any of the symptoms of difficult breathing, in the Symptoms section above.

Also call your health care provider right away if you:

• Have a cold or other respiratory infection and are having difficulty breathing
• Have a cough that does not go away after 2 or 3 weeks
• Are coughing up blood
• Are losing weight without meaning to or having night sweats
• Cannot get to sleep or wake up at night because of breathing difficulty
• Notice it is hard to breathe when doing things that you normally do without breathing difficulty, for example, climbing stairs

Also call your provider if your child has a cough and is making a barking sound or wheezing.

Some things you can do to help prevent breathing problems:

• If you have a history of severe allergic reactions, carry an epinephrine pen and wear a medical alert tag. Your provider will teach you how to use the epinephrine pen.
• If you have asthma or allergies, eliminate household allergy triggers like dust mites and mold.
• DO NOT smoke, and keep away from secondhand smoke. DO NOT allow smoking in your home.
• If you have asthma, see the article on asthma to learn ways to manage it.
• Make sure your child gets the whooping cough (pertussis) vaccine.
• Make sure your tetanus booster, influenza, and COVID-19 vaccines are up to date.
• When traveling by airplane, get up and walk around every few hours to avoid forming blood clots in your legs. Once formed, clots can break off and lodge in your lungs. While seated, do ankle circles and raise and lower your heels, toes, and knees to increase blood flow in your legs. If traveling by car, stop and get out and walk around regularly.
• If you are overweight, lose weight. You are more likely to feel winded if you are overweight. You are also at greater risk for heart disease and heart attack.

Wear a medical alert tag if you have a pre-existing breathing condition, such as asthma.
