Respiratory care is an allied health specialty that provides a wide range of therapeutic and diagnostic services to people with heart and lung disorders.
Respiratory therapists, also known as respiratory care practitioners, are involved in evaluating and monitoring heart and lung function as well as giving treatment.
Respiratory therapists are important members of the health care team. They work under the medical direction of doctors to treat all types of patients, ranging from premature infants whose lungs are not fully developed to elderly people with lung disease. They provide temporary relief to patients with chronic asthma or emphysema, as well as emergency care to patients who are experiencing a heart attack, stroke, drowning or shock.
Respiratory care is a professionally and personally rewarding career with a balanced blend of technology and patient interaction.
Specific care provided by respiratory therapists may include:
- Administration of oxygen
- Cardiopulmonary resuscitation
- Management of mechanical ventilators
- Administering drugs to the lungs
- Monitoring cardiopulmonary systems
- Measuring lung function

This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack.
Asthma can’t be cured, but its symptoms can be controlled. Because asthma often changes over time, it’s important that you work with your doctor to track your signs and symptoms and adjust treatment as needed.
Asthma symptoms vary from person to person. You may have infrequent asthma attacks, have symptoms only at certain times — such as when exercising — or have symptoms all the time.
Asthma signs and symptoms include:
- Shortness of breath
- Chest tightness or pain
- Trouble sleeping caused by shortness of breath, coughing or wheezing
- A whistling or wheezing sound when exhaling (wheezing is a common sign of asthma in children)
- Coughing or wheezing attacks that are worsened by a respiratory virus, such as a cold or the flu
Signs that your asthma is probably worsening include:
- Asthma signs and symptoms that are more frequent and bothersome
- Increasing difficulty breathing (measurable with a peak flow meter, a device used to check how well your lungs are working)
- The need to use a quick-relief inhaler more often
For some people, asthma signs and symptoms flare up in certain situations:
- Exercise-induced asthma, which may be worse when the air is cold and dry
- Occupational asthma, triggered by workplace irritants such as chemical fumes, gases or dust
- Allergy-induced asthma, triggered by airborne substances, such as pollen, mold spores, cockroach waste or particles of skin and dried saliva shed by pets (pet dander)
When to see a doctor
Seek emergency treatment
Severe asthma attacks can be life-threatening. Work with your doctor to determine what to do when your signs and symptoms worsen — and when you need emergency treatment. Signs of an asthma emergency include:
- Rapid worsening of shortness of breath or wheezing
- No improvement even after using a quick-relief inhaler, such as albuterol
- Shortness of breath when you are doing minimal physical activity
Contact your doctor
See your doctor:
- If you think you have asthma. If you have frequent coughing or wheezing that lasts more than a few days or any other signs or symptoms of asthma, see your doctor. Treating asthma early may prevent long-term lung damage and help keep the condition from worsening over time.
- To monitor your asthma after diagnosis. If you know you have asthma, work with your doctor to keep it under control. Good long-term control helps you feel better from day to day and can prevent a life-threatening asthma attack.
- If your asthma symptoms get worse. Contact your doctor right away if your medication doesn’t seem to ease your symptoms or if you need to use your quick-relief inhaler more often. Don’t try to solve the problem by taking more medication without consulting your doctor. Overusing asthma medication can cause side effects and may make your asthma worse.
- To review your treatment. Asthma often changes over time. Meet with your doctor regularly to discuss your symptoms and make any needed treatment adjustments.

Your immune system produces substances known as antibodies. Some antibodies protect you from unwanted invaders that could make you sick or cause infection.
When you have allergies, your immune system makes antibodies that identify a particular allergen as harmful, even though it isn’t. When you come into contact with the allergen, your immune system’s reaction can inflame your skin, sinuses, airways or digestive system.
The severity of allergies varies from person to person and can range from minor irritation to anaphylaxis — a potentially life-threatening emergency. While most allergies can’t be cured, a number of treatments can help relieve your allergy symptoms.
Allergy symptoms depend on the substance involved and can involve the airways, sinuses and nasal passages, skin, and digestive system. Allergic reactions can range from mild to severe. In some severe cases, allergies can trigger a life-threatening reaction known as anaphylaxis.
Hay fever, also called allergic rhinitis, may cause:
- Itching of the nose, eyes or roof of the mouth
- Runny, stuffy nose
- Watery, red or swollen eyes (conjunctivitis)
A food allergy may cause:
- Tingling mouth
- Swelling of the lips, tongue, face or throat
An insect sting allergy may cause:
- A large area of swelling (edema) at the sting site
- Itching or hives all over your body
- Cough, chest tightness, wheezing or shortness of breath
A drug allergy may cause:
- Itchy skin
- Facial swelling
Atopic dermatitis, an allergic skin condition also called eczema, may cause skin to:
- Flake or peel
Some types of allergies, including allergies to foods and insect stings, have the potential to trigger a severe reaction known as anaphylaxis. A life-threatening medical emergency, this reaction can cause you to go into shock. Signs and symptoms of anaphylaxis include:
- Loss of consciousness
- A drop in blood pressure
- Severe shortness of breath
- Skin rash
- A rapid, weak pulse
- Nausea and vomiting
When to see a doctor
You might see a doctor if you have symptoms you think may be caused by an allergy, especially if you notice something that seems to trigger your allergies. If you have symptoms after starting a new medication, call the doctor who prescribed it right away.
For a severe allergic reaction (anaphylaxis), call 911 or your local emergency number or seek emergency medical help. If you carry an epinephrine auto-injector (such as EpiPen, Auvi-Q, others), give yourself a shot right away.
Even if symptoms improve after an epinephrine injection, a visit to the emergency department is still necessary to make sure symptoms don’t return when the effects of the injection wear off.
If you’ve had a severe allergy attack or any signs and symptoms of anaphylaxis in the past, make an appointment to see your doctor. Evaluation, diagnosis and long-term management of anaphylaxis are complicated, so you’ll probably need to see a doctor who specializes in allergies and immunology.[/vc_column_text][/vc_tta_section][vc_tta_section title=”COPD” tab_id=”1478789295821-6dd4babe-fbb1″][vc_column_text]
What Is COPD?
COPD, or chronic obstructive pulmonary (PULL-mun-ary) disease, is a progressive disease that makes it hard to breathe. “Progressive” means the disease gets worse over time.
COPD can cause coughing that produces large amounts of mucus (a slimy substance), wheezing, shortness of breath, chest tightness, and other symptoms.
Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. Long-term exposure to other lung irritants—such as air pollution, chemical fumes, or dust—also may contribute to COPD.
To understand COPD, it helps to understand how the lungs work. The air that you breathe goes down your windpipe into tubes in your lungs called bronchial (BRONG-ke-al) tubes or airways.
Within the lungs, your bronchial tubes branch into thousands of smaller, thinner tubes called bronchioles (BRONG-ke-ols). These tubes end in bunches of tiny round air sacs called alveoli (al-VEE-uhl-eye).
Small blood vessels called capillaries (KAP-ih-lare-ees) run through the walls of the air sacs. When air reaches the air sacs, oxygen passes through the air sac walls into the blood in the capillaries. At the same time, carbon dioxide (a waste gas) moves from the capillaries into the air sacs. This process is called gas exchange.
The airways and air sacs are elastic (stretchy). When you breathe in, each air sac fills up with air like a small balloon. When you breathe out, the air sacs deflate and the air goes out.
In COPD, less air flows in and out of the airways because of one or more of the following:
- The airways and air sacs lose their elastic quality.
- The walls between many of the air sacs are destroyed.
- The walls of the airways become thick and inflamed.
- The airways make more mucus than usual, which can clog them.
Normal Lungs and Lungs With COPD
In the United States, the term “COPD” includes two main conditions—emphysema (em-fih-SE-ma) and chronic bronchitis (bron-KI-tis). (Note: The Health Topics article about bronchitis discusses both acute and chronic bronchitis.)
In emphysema, the walls between many of the air sacs are damaged. As a result, the air sacs lose their shape and become floppy. This damage also can destroy the walls of the air sacs, leading to fewer and larger air sacs instead of many tiny ones. If this happens, the amount of gas exchange in the lungs is reduced.
In chronic bronchitis, the lining of the airways is constantly irritated and inflamed. This causes the lining to thicken. Lots of thick mucus forms in the airways, making it hard to breathe.
Most people who have COPD have both emphysema and chronic bronchitis. Thus, the general term “COPD” is more accurate.
COPD is a major cause of disability, and it’s the third leading cause of death in the United States. Currently, millions of people are diagnosed with COPD. Many more people may have the disease and not even know it.
COPD develops slowly. Symptoms often worsen over time and can limit your ability to do routine activities. Severe COPD may prevent you from doing even basic activities like walking, cooking, or taking care of yourself.
Most of the time, COPD is diagnosed in middle-aged or older adults. The disease isn’t passed from person to person—you can’t catch it from someone else.
COPD has no cure yet, and doctors don’t know how to reverse the damage to the airways and lungs. However, treatments and lifestyle changes can help you feel better, stay more active, and slow the progress of the disease.
