A Respiratory Therapist is someone who cares for patients that have trouble breathing; for example, from a chronic respiratory disease, such as asthma or emphysema. They also provide emergency care to patients suffering from heart attacks, stroke, drowning, or shock. Respiratory Therapists use various tests to evaluate patients. For example, they test lung capacity by having patients breathe into an instrument that measures the volume and flow of oxygen when they inhale and exhale. They may also take blood samples and use a blood gas analyzer to test the oxygen and carbon dioxide levels present. Respiratory Therapists perform chest physiotherapy on patients to remove mucus from their lungs and make it easier for them to breathe. Removing mucus is necessary for patients suffering from lung diseases, such as cystic fibrosis, and involves the therapist vibrating the patient’s rib cage, often by tapping the patient’s chest and encouraging him or her to cough.

Respiratory therapists may connect patients who cannot breathe on their own to ventilators to deliver oxygen to the lungs. They insert a tube into the patient’s windpipe (trachea) and connect the tube to ventilator equipment. They set and monitor the equipment to ensure that the patient is receiving the correct amount of oxygen at the correct rate. Respiratory Therapists who work in home care teach patients and their families to use ventilators and other lifesupport systems in their homes. During these visits, they may inspect and clean equipment, check the home for environmental hazards, and ensure that patients know how to use their medications. Therapists also make emergency home visits when necessary. The duties of Respiratory Therapist includes to diagnosing lung and breathing disorders and recommending treatment methods and to interviewing patients and doing chest physical exams to determine what kind of therapy is best for their condition.


They should also do consulting with physicians to recommend a change in therapy, based on an evaluation of the patient and to analyzing breath, tissue, and blood specimens to determine levels of oxygen and other gases. Managing ventilators and artificial airway devices for patients who can’t breathe normally on their own and educating patients and families about lung disease so they can maximize their recovery.
