The Dyspnea Clinic at U of U Health was the first of its kind in the western United States combining the expertise of both a pulmonologist and cardiologist in the same clinic. Cardiologists and pulmonologists at U of U Health work together to diagnose and treat patients for a wide variety of heart or lung conditions that cause dyspnea, or shortness of breath. This combined expertise clinic is the only clinic in the Mountain West region to bring together these specialists for diagnosing the causes of dyspnea.
We offer advanced imaging and other diagnostic studies that provide insight into causes and conditions beyond what a typical medical office is able to identify. As an academic research facility, we also keep up with all the latest studies and treatments in cardiology and pulmonology to provide our patients with the most advanced care for shortness of breath.
Types of Dyspnea
There are different terms used to describe shortness of breath, depending on how it occurs:
- Nocturnal dyspnea鈥This occurs mostly at night when you are sleeping.
- Exertional dyspnea鈥This occurs when you are exerting your body during activities such as intense exercise.
- 翱谤迟丑辞辫苍别补鈥This occurs when you experience shortness of breath and discomfort while lying down. This is usually a sign of heart failure. Lying down should make it easier for your heart to pump blood throughout your body. However, if you have orthopnea, your heart is not strong enough to pump all the blood out. Extra blood leaks into your lungs and makes it harder to breathe in this position.
Dyspnea Symptoms
The most common symptom of dyspnea is having trouble breathing or feeling unable to catch your breath. It can happen when you are:
- exerting yourself during exercise,
- doing normal daily activities, or
- while sitting or lying down.
Other symptoms associated with dyspnea might include:
- tingling in your chest,
- tightness in your chest,
- edema (swelling in your legs and feet),
- fingers and toes that turn blue or look discolored,
- a feeling of suffocating, or
- lightheadedness.
What to Do When Experiencing Shortness of Breath
If you experience shortness of breath that comes on suddenly, go to the emergency room or call 911 to get help right away. For mild shortness of breath, sit down or find a place that you can rest until you catch your breath.
Dyspnea Causes
Dyspnea is a common symptom of heart and/or lung disease.
Conditions that can put you at higher risk of developing dyspnea include:
- pulmonary fibrosis or interstitial lung disease (inflammation and scarring in the air sacs and blood vessels of the lungs),
- chronic obstructive pulmonary disease (COPD),
- emphysema,
- asthma,
- obesity,
- obstructive sleep apnea,
- cystic fibrosis,
- pulmonary hypertension,
- valvular heart disease,
- ischemic heart disease (chest pain when parts of your heart do not get enough blood), or
- previous heart attack(s).
When to See a Doctor for Shortness of Breath
If dyspnea comes on suddenly and is persistent, go to the nearest emergency room or call 911.
Some people may blame shortness of breath on getting older or being out of shape. However, dyspnea can be a sign of more serious health problems. See a doctor if you have shortness of breath, especially if you notice it getting worse over time.
You should also see a specialist if you wake up several times during the night with shortness of breath or you are extremely tired and cannot stay awake during the day. These may be signs of an obstructive sleep disorder.
Oxygen Levels & Shortness of Breath
You can measure oxygen levels at home with a low-cost device called a pulse oximetry meter (or pulse oximeter). These devices are available online or at your local pharmacy.
A pulse oximeter clips on the end of your finger. After a few seconds, it gives a reading of how well your blood is pumping oxygen to your body, up to 100 percent (complete oxygen saturation). Healthy adults should have oxygen levels above 92 percent, and ideally above 95 percent. If your oximeter reading is 90 percent or below, see a doctor.
How Do I Know If My Shortness of Breath Is Heart-Related?
It can be difficult for you to know whether your dyspnea is the result of a problem with your heart, your lungs, or both. The first step to finding the cause of your dyspnea is to get the correct tests and an accurate diagnosis from a cardiology or pulmonary specialist.
How Dyspnea Is Diagnosed
If you have dyspnea, your primary care provider may do some basic tests to try to figure out the cause. These include:
- electrocardiogram (EKG or ECG),
- echocardiography,
- chest X-ray,
- spirometry and diffusing capacity breathing test (breathing into a tube several times to measure lung function), or
- various blood tests.
However, these tests do not always reveal the reason for your shortness of breath.
Getting Tested at the Dyspnea Clinic
The Dyspnea Clinic at U of U Health provides in-depth, specialized testing options to learn more about what might be causing your dyspnea. Primary health care clinics do not offer these tests so you will need to see one of our dyspnea specialists to get them done.
Additional tests may include:
- Left or right heart catheter鈥We will insert a small, thin flexible tube into the left or right side of your heart to diagnose heart problems.
- Cardiac imaging scans鈥We can use several types of imaging scans to see what is happening in the muscles and tissues in and around your heart. These include cardiac MRI, cardiac CT, and chest CT scans.
- Stress and exercise testing鈥We will ask you to do different exercises to see how your body handles exercise and monitor your heart rate, breathing, and blood pressure. These include cardiac stress tests, cardiopulmonary exercise testing (CPET), and six-minute walk tests (6MWT).
- 叠谤辞苍肠丑辞蝉肠辞辫测鈥We will insert a thin tube with a camera into the lungs so we can see the airways inside your lungs. We will also take tissue samples, if necessary. We can also use a special type of bronchoscope (EBUS) with an ultrasound probe on the end to localize specific areas in the lungs.
- Overnight oximetry鈥We will monitor the oxygen levels in your blood continuously throughout the night. This is typically done at home with a device on your finger.
- 笔辞濒测蝉辞尘苍辞驳谤补辫丑测鈥We will monitor your brain waves, oxygen levels, heart rate, and breathing during a sleep test.
- 叠颈辞辫蝉测鈥We will take a small sample of tissue from your heart, lungs, or other part of your body and send it to the lab for testing to help determine specific diagnoses.
- 罢丑辞谤补肠别苍迟别蝉颈蝉鈥We will insert a needle into your chest to remove fluid from a small area between your lungs and your chest wall. Fluid in this area can make it harder to breathe.
- Lung VQ scan鈥We will use ventilation (V) scans to measure air flow and perfusion (Q) scans to measure blood flow in your lungs.
- Positional pulmonary function tests (PFTs)鈥We will measure your breathing and lung function in different positions, such as standing up, sitting, and lying down.
Dyspnea Treatment
The treatment of dyspnea depends on the specific diagnosis causing your shortness of breath. The specialists at U of U Health have extensive experience diagnosing conditions that cause shortness of breath. Once you have a diagnosis, our specialists at the Dyspnea Clinic will provide treatment recommendations or refer you to the right specialist for further care.
