A respiratory therapist is a healthcare professional who helps people breathe better when illness, injury, or a medical condition affects the lungs. They work with patients of many ages, from premature babies to older adults with chronic lung disease. This career matters because breathing problems can become emergencies very quickly, and skilled care can save lives.
It is a strong career choice for students who enjoy science, technology, teamwork, and helping people directly.
Key Facts
- Respiratory therapists assess breathing by checking breathing rate, lung sounds, oxygen saturation, and patient symptoms.
- Oxygen saturation, written SpO2, is often measured with a pulse oximeter and is commonly expected to be about 95% to 100% in many healthy people.
- Breathing rate = number of breaths counted ÷ time in minutes.
- They use tools such as oxygen masks, nebulizers, ventilators, suction devices, and pulmonary function testing equipment.
- Common work settings include hospitals, emergency departments, intensive care units, sleep labs, clinics, rehabilitation centers, and home care.
- The education path usually includes strong high school science courses, an accredited respiratory therapy program, clinical practice, and a professional licensing exam.
Vocabulary
- Respiratory Therapist
- A respiratory therapist is a licensed healthcare worker trained to evaluate and treat patients with breathing or heart-lung problems.
- Ventilator
- A ventilator is a machine that helps move air into and out of a patient's lungs when they cannot breathe well enough on their own.
- Nebulizer
- A nebulizer is a device that turns liquid medicine into a mist that a patient can breathe into the lungs.
- Oxygen Saturation
- Oxygen saturation is the percentage of hemoglobin in the blood that is carrying oxygen.
- Pulmonary Function Test
- A pulmonary function test measures how well a person's lungs move air and exchange gases.
Common Mistakes to Avoid
- Thinking respiratory therapists only give oxygen is wrong because they also assess patients, manage ventilators, give breathing treatments, perform tests, and respond to emergencies.
- Ignoring biology and chemistry classes is a mistake because respiratory therapy depends on understanding lungs, blood gases, medications, infection control, and body systems.
- Assuming the job is done alone is wrong because respiratory therapists work closely with nurses, doctors, physical therapists, patients, and families.
- Reading a pulse oximeter number without looking at the patient is a mistake because devices can be affected by movement, cold fingers, nail polish, poor circulation, or other clinical factors.
Practice Questions
- 1 A respiratory therapist counts 18 breaths in 30 seconds. What is the patient's breathing rate in breaths per minute?
- 2 A clinic sees 24 patients in a day, and 3 out of every 8 patients need a breathing treatment. How many patients receive a breathing treatment?
- 3 A student likes biology, helping people, technology, and working on a team, but feels nervous about emergencies. Explain why respiratory therapy might still be a good career to explore and what skills the student should practice.
