BREATHING WARNING SIGNS
When Is Shortness of Breath an Emergency?
Shortness of breath is an emergency when it comes on suddenly, happens at rest, keeps getting worse, or comes with chest pain, wheezing that doesn’t improve with your inhaler, a racing heart, fainting, confusion, coughing up blood, or swelling of the lips, tongue, or throat. Blue or gray lips or skin mean oxygen may be dangerously low.
Breathing trouble can come from the lungs, the heart, the airways, a blood clot, a severe allergic reaction, or anxiety. Because several of these are life-threatening, new or severe breathlessness should never be assumed to be “just anxiety.”
Get emergency care for breathlessness with:
- Sudden onset, or breathlessness at rest
- Chest pain or pressure
- Wheezing your inhaler doesn’t relieve
- Blue or gray lips or fingertips
- Fainting or confusion
- Coughing up blood
- One swollen, painful leg
- Throat or tongue swelling

Short of Breath? We’re Open 24/7
Emergency evaluation is available day and night at The Heights Emergency Room.
Sudden Shortness of Breath
Breathlessness that starts abruptly, especially at rest, needs prompt evaluation.
Possible serious causes
- A blood clot in the lungs (pulmonary embolism)
- A collapsed lung (pneumothorax)
- A severe asthma or COPD attack
- Fluid in the lungs from heart failure
- A severe allergic reaction (anaphylaxis)
The risk of a blood clot rises after surgery, a long trip, prolonged bed rest, pregnancy, or hormone use, especially if one leg is swollen.
Chest Pain With Shortness of Breath
Chest pain and breathlessness together can signal a heart attack, a blood clot in the lungs, or another emergency.
Pressure, tightness, or pain in the chest with breathlessness, sweating, nausea, or pain spreading to the arm or jaw should be treated as an emergency. Call 911 for severe symptoms. Learn more on our chest pain ER page.
Wheezing and Asthma Attacks
Wheezing means the airways are narrowed, which can happen with asthma, COPD, infections, or allergic reactions.
Go to the ER for wheezing with
- Little or no relief from your rescue inhaler
- Needing your inhaler more often than every 4 hours
- Trouble speaking in full sentences
- Skin pulling in between the ribs with each breath
- Drowsiness or confusion
If you use a peak flow meter, a reading below half of your personal best is a sign of a severe attack.
COPD and Heart Failure Flares
People with chronic lung or heart conditions can have sudden flares that need emergency care.
Worsening breathlessness, more coughing or mucus, swelling in the legs, sudden weight gain, or needing to sleep propped up can signal a COPD or heart failure flare. Get help if your usual medications aren’t working or you’re breathless at rest. Breathing trouble with fever may be a respiratory infection.
CHILDREN & ALLERGIES
Breathing Trouble in Children and After an Allergic Exposure
Children and people having allergic reactions can worsen quickly.
In children, watch for fast breathing, grunting, flaring nostrils, skin pulling in at the ribs or neck, noisy breathing, or a child who is too breathless to eat, talk, or cry normally. See our pediatric emergency care page.
Breathing trouble after a food, medication, or insect sting—especially with hives or swelling of the lips, tongue, or throat—can be anaphylaxis. Use an epinephrine auto-injector if one is prescribed, and call 911.
YOUR ER VISIT
What Happens When You Visit the ER for Shortness of Breath?
Breathing difficulty is treated as a priority. The team checks your oxygen level, breathing rate, heart rate, and blood pressure, and listens to your heart and lungs.
Oxygen & Breathing Support
Supplemental oxygen and nebulizer breathing treatments may be started right away when needed.
Imaging
A chest X-ray can show pneumonia, fluid, or a collapsed lung; a CT scan can look for blood clots in the lungs.
Heart & Lab Tests
An EKG and blood tests such as troponin, BNP, or D-dimer can help find heart- or clot-related causes.
Testing and treatment depend on your evaluation. Patients who need hospital admission or specialist care are transferred.
What Can Cause Shortness of Breath?
An emergency physician may consider:
Lung Conditions
Asthma, COPD, pneumonia, a collapsed lung, or a blood clot in the lungs.
Heart Conditions
Heart attack, heart failure, abnormal heart rhythms, or fluid around the heart.
Allergic Reactions
Anaphylaxis and airway swelling from foods, medications, or stings.
Other Causes
Severe anemia, anxiety or panic attacks, and certain metabolic problems.
Anxiety can cause breathlessness, but it should be considered only after other causes are ruled out. This list is general information, not a diagnosis.

When is shortness of breath an emergency?
Shortness of breath is an emergency when it is sudden, happens at rest, keeps worsening, or comes with chest pain, wheezing that doesn’t respond to your inhaler, a racing heart, fainting, confusion, coughing up blood, swelling of the lips or throat, or blue or gray lips. These can signal a heart, lung, or allergic emergency.
Should I go to the ER for wheezing and difficulty breathing?
Yes, if your rescue inhaler isn’t helping, you need it more often than every four hours, or you’re struggling to speak, walk, or stay alert. An emergency room can provide oxygen, nebulizer treatments, and steroid medication when appropriate. Call 911 for severe distress or blue lips.
Is chest pain with shortness of breath an emergency?
Yes. Chest pain with shortness of breath can be a sign of a heart attack, a blood clot in the lungs, a collapsed lung, or another serious condition, and it needs immediate evaluation. Call 911 if symptoms are severe or sudden or come with sweating, fainting, or pain spreading to the arm or jaw.
Should I call 911 if I can barely breathe?
Yes. If you can barely breathe, can’t speak in full sentences, or have blue or gray lips, call 911 immediately rather than driving. Paramedics can give oxygen and breathing treatments on the way. Sit upright, use your rescue inhaler or epinephrine if prescribed, and unlock the door for responders.

FAQ
Shortness of Breath ER — Frequently Asked Questions
Yes, anxiety and panic attacks can cause a feeling of breathlessness. But because heart, lung, and allergic emergencies can feel similar, new or severe shortness of breath should be evaluated before it’s attributed to anxiety.
For most healthy adults, a pulse oximeter reading below 92% is a reason to seek care, and a reading below 90% is concerning. People with chronic lung disease may have a different target set by their doctor.
Yes. Bring your inhalers and a list of your medications, and tell the staff what you used and when.
Yes. A blood clot in the lungs can cause sudden breathlessness, sharp chest pain, a fast heart rate, or coughing up blood. It is an emergency, especially after surgery or travel or with a swollen leg.
Usually not if it’s mild and improving. Seek care if breathing becomes difficult at rest, you develop chest pain or a high fever, or you have asthma or COPD that isn’t responding to treatment.
Yes. The Heights Emergency Room evaluates children 24/7 and has a patient room dedicated to pediatric patients. Call 911 for a child who is struggling to breathe.
