Respiratory therapists play a crucial role in the healthcare system by helping patients with breathing difficulties and respiratory disorders. As specialised healthcare professionals, they work closely with doctors, nurses, and other medical staff to provide essential care for patients suffering from acute and chronic respiratory conditions. The demand for respiratory therapists has grown significantly, especially during health crises like the COVID-19 pandemic, highlighting their importance in critical care and rehabilitation.
If you are interested in pursuing a career in healthcare or are looking to support your medical career financially, options such as a doctor loan can help you manage expenses related to education and professional development.
Who is a respiratory therapist?
A respiratory therapist (RT) is a trained healthcare professional who helps patients of all ages—from newborns to the elderly—who have breathing or heart-lung problems such as asthma, COPD, or pneumonia. They work alongside doctors in hospitals, emergency rooms, and intensive care units, managing ventilators, giving oxygen, and carrying out tests to check lung and heart function.
Roles and responsibilities of a respiratory therapist
Respiratory therapists perform several critical functions in patient care, including:
- Assessing patients’ respiratory conditions using diagnostic tools like spirometry and arterial blood gas analysis.
- Administering respiratory therapy treatments such as oxygen therapy, inhalation therapy, and mechanical ventilation.
- Monitoring ventilators and other respiratory support devices for critically ill patients in ICUs.
- Educating patients and families about managing chronic respiratory diseases and preventive care.
- Collaborating with physicians and healthcare teams to develop and implement treatment plans.
- Responding to emergency situations requiring immediate respiratory intervention.
- Maintaining and calibrating respiratory equipment to ensure safety and efficacy.
Common conditions treated by respiratory therapists
Respiratory therapists are involved in treating a range of respiratory illnesses and conditions, including:
- Asthma – Managing airway inflammation and preventing attacks.
- Chronic Obstructive Pulmonary Disease (COPD) – Assisting patients in managing symptoms and improving quality of life.
- Pneumonia – Supporting oxygen therapy and ventilation needs.
- Bronchitis – Providing treatments to ease airway obstruction and inflammation.
- Cystic fibrosis – Assisting with airway clearance and breathing support.
- Respiratory failure – Managing mechanical ventilation and oxygen delivery.
- Sleep apnoea – Administering CPAP therapy and other treatments.
What to expect during your visit to a respiratory therapist
If you have an appointment with a respiratory therapist, your experience may vary depending on the reason for your visit.
For instance, someone attending an asthma check-up may undergo different tests or procedures than someone being treated for lung cancer. Any preparations, such as stopping certain medications beforehand, will also depend on your individual medical condition.
Despite these differences, most visits follow a similar pattern. First, you and the respiratory therapist will discuss the reason for your referral. The therapist will review your medical records and symptoms, and may ask additional questions to clarify details or cover information not included in your file.
Depending on your needs, the respiratory therapist may:
- Listen to your lungs and carry out a physical examination
- Check your blood oxygen levels
- Perform a pulmonary function test to assess your breathing
- Send blood samples to a lab
- Explain treatments prescribed by your doctor
- Administer treatments directly
- Set up and show you how to use equipment, such as inhalers or other respiratory devices
- Discuss your treatment progress, address any issues, and answer your questions
- Refer you back to your doctor if the current treatment isn’t effective or if concerns arise

If you are interested in this rewarding healthcare career, here are the typical steps:
If you want to become a respiratory therapist in India, you must follow the guidelines set by Indian regulatory and educational authorities.
Complete your education:
You need to earn a diploma or degree in respiratory therapy/respiratory care from a recognised Indian institution. The main courses in India are:
- Diploma in Respiratory Therapy (DRT): 2-year programme
- Bachelor of Science in Respiratory Therapy (B.Sc. RT): 3–4-year programme, preferred for better job prospects

Registration ensures you are eligible to practise in healthcare institutions.
Practical training and internships:
Most Indian courses require hands-on clinical training in hospitals, including working in:
- Intensive Care Units (ICU)
- Pulmonology departments
- Emergency and critical care units
During this period, you learn to manage ventilators, administer oxygen therapy, perform pulmonary function tests, and assist in critical care procedures.
Continuing education and specialisation:
After completing your basic degree or diploma, you can pursue advanced certification or specialisation in areas such as:
- Pulmonary Function Testing (PFT) Specialist
- Critical Care Respiratory Therapy
- Neonatal and Paediatric Respiratory Care
- Sleep Disorders Therapy
- Asthma Educator and Pulmonary Rehabilitation
Employment and career prospects in India:
Respiratory therapists in India work primarily in:
- Tertiary care hospitals and ICU units
- Pulmonology and critical care departments
- Sleep labs and pulmonary function labs
- Home healthcare and rehabilitation centres
To maintain competence, it is recommended to attend workshops, refresher courses, and certifications recognised by professional bodies such as IARC or hospital training programmes.

When to see a respiratory therapist
Although respiratory therapists are part of the medical team, they work under the supervision of a doctor. This means you cannot usually book an appointment with a respiratory therapist directly. Instead, your doctor may refer you to a respiratory therapist if you have any of the following:
- A persistent cough that does not go away
- Coughing up blood, provided it does not require emergency care
- Wheezing, a high-pitched sound when exhaling, which is not an emergency
- Shortness of breath (dyspnoea) that is not urgent
- Chest pain or pressure unrelated to heart problems
- Abnormal chest X-ray findings or low oxygen levels indicated by blood tests, without the need for emergency treatment
If you require breathing devices or equipment, a respiratory therapist can guide you on how to use them correctly and maintain them safely.
Conclusion
Respiratory therapy is a vital and rewarding healthcare profession dedicated to improving patients’ breathing and overall lung health. The career offers strong growth potential and the opportunity to make a meaningful difference in patients’ lives. With the right education, certification, and practical skills, you can build a successful career in this dynamic field. For medical professionals seeking financial support, a professional loan or doctor loan can help with career advancement, further studies, or purchasing essential equipment, while healthcare financing solutions make it easier to manage expenses related to clinical practice and patient care.
