Pulmonologists: Guardians of Our Breathing

Breathing is a vital function of human life, and it is essential to take care of our lung health. Pulmonologists are medical professionals who specialize in diagnosing and treating lung-related diseases and disorders. They play a crucial role in managing and maintaining respiratory health, but many people are unaware of what a pulmonologist does. In this article, we will explore the scope of work of what does a pulmonologist do.

Diagnosis and Treatment of Lung Diseases:

Pulmonologists are responsible for diagnosing and treating a wide range of diseases that affect the respiratory system. Some common conditions they treat are asthma, chronic obstructive pulmonary disease (COPD), emphysema, lung cancer, and pneumonia. They use various diagnostic tools such as pulmonary function tests, bronchoscopy, and imaging techniques to identify the underlying cause of the disease. Once diagnosed, the pulmonologist provides the patient with a personalized treatment plan, which may include medication, inhalers, oxygen therapy, or surgery.

Managing Chronic Respiratory Diseases:

Pulmonologists often manage patients with chronic respiratory diseases such as asthma and COPD. These conditions require ongoing care and monitoring to prevent symptoms from worsening. The pulmonologist works closely with the patient to develop a long-term management plan that may include lifestyle changes, medication, and breathing exercises. They also monitor the patient’s progress and make adjustments to the treatment plan as needed.

Sleep Medicine:

Many pulmonologists specialize in sleep medicine, which focuses on diagnosing and treating sleep-related disorders such as sleep apnea. Sleep apnea is a common condition in which breathing stops and starts during sleep, leading to reduced oxygen levels in the body. Pulmonologists use sleep studies and other tests to diagnose sleep apnea and develop a treatment plan. This may include lifestyle changes, continuous positive airway pressure (CPAP) therapy, or surgery.

Critical Care:

Pulmonologists also play a crucial role in critical care settings such as the intensive care unit (ICU). Patients in the ICU often require mechanical ventilation or other advanced respiratory support. The pulmonologist is responsible for managing and monitoring the patient’s respiratory function. They work closely with other healthcare professionals to ensure that the patient receives the appropriate care and treatment.


Lastly, many pulmonologists engage in research to advance our understanding of respiratory health and develop new treatments. Research may involve conducting clinical trials, studying the functioning of the respiratory system, and exploring new diagnostic techniques. By staying up-to-date with the latest research, pulmonologists can provide their patients with the most effective and personalized care.


In conclusion, pulmonologists play a crucial role in diagnosing and treating a wide range of lung diseases and disorders. They also manage chronic respiratory diseases, provide sleep medicine, care for critically ill patients, and conduct innovative research. If you’re experiencing breathing problems or have a lung-related condition, it’s essential to seek the advice of a pulmonologist. They can provide you with a personalized treatment plan and help you maintain good respiratory health.
