Pulmonary Function Test (PFT) - Complete Lung Function Evaluation in Hyderabad
Dr. Raju's Sleep Centre & Multispeciality Hospital in Chandanagar, Hyderabad offers comprehensive Pulmonary Function Testing (PFT) under the expert supervision of Dr. Raju CH, MBBS, MD Pulmonary Medicine. Pulmonary function tests are non-invasive diagnostic procedures that measure how well your lungs are working, assessing lung volume, capacity, flow rates, and gas exchange. With over 18 years of specialized experience in pulmonary medicine, Dr. Raju utilizes advanced PFT equipment to diagnose asthma, chronic obstructive pulmonary disease (COPD), restrictive lung diseases, and other respiratory conditions that may impact sleep quality and overall health. Accurate pulmonary function testing is essential for patients with sleep disorders, as respiratory conditions often contribute to or worsen sleep-related breathing problems.
What is Pulmonary Function Testing?
Pulmonary Function Testing (PFT) is a comprehensive group of non-invasive tests that measure how well your lungs take in and exhale air and how efficiently they transfer oxygen into your bloodstream. These tests provide critical information about lung volume, capacity, flow rates, and diffusion capacity. At Dr. Raju's Sleep Centre & Multispeciality Hospital in Chandanagar, Hyderabad, we use state-of-the-art PFT equipment including spirometry, body plethysmography, and gas diffusion testing to accurately assess respiratory function. Dr. Raju CH, with his extensive background in pulmonary medicine, personally interprets these results to diagnose respiratory conditions, evaluate disease severity, monitor treatment effectiveness, and assess pre-operative risk. Pulmonary function testing is particularly important for sleep medicine patients, as undiagnosed respiratory conditions can significantly impact sleep quality and contribute to sleep-disordered breathing.
Why is Pulmonary Function Testing Important at Dr. Raju's Sleep Centre, Hyderabad?
Respiratory health and sleep quality are deeply interconnected. Conditions such as asthma, COPD, and restrictive lung diseases can significantly disrupt sleep, leading to frequent nighttime awakenings, reduced oxygen levels, and increased risk of sleep-disordered breathing. Conversely, sleep apnea can worsen underlying respiratory conditions. At Dr. Raju's Sleep Centre & Multispeciality Hospital, pulmonary function testing helps Dr. Raju CH identify respiratory conditions that may be contributing to your sleep problems, assess the severity of existing lung disease, determine appropriate treatment strategies, and monitor response to therapy. For patients with sleep apnea, PFT helps evaluate the impact of obesity on lung function and guides decisions about respiratory support during sleep. With 18 years of experience in pulmonary medicine, Dr. Raju integrates PFT results with sleep study findings to provide comprehensive, coordinated care.
Types of Pulmonary Function Tests at Dr. Raju's Sleep Centre & Multispeciality Hospital, Chandanagar, Hyderabad
Our Hyderabad sleep centre offers a complete range of pulmonary function tests tailored to each patient's specific needs. Spirometry is the most common initial test, measuring how much air you can inhale and exhale and how quickly you can exhale. This test helps diagnose asthma and COPD. Lung volume measurement (body plethysmography) assesses total lung capacity, residual volume, and other volumes that help differentiate between obstructive and restrictive lung diseases. Diffusion capacity testing measures how well oxygen passes from your lungs into your bloodstream. Bronchodilator responsiveness testing evaluates how your airways respond to medication. Dr. Raju CH determines which tests are appropriate based on your symptoms, medical history, and suspected conditions, ensuring comprehensive evaluation of your respiratory health.

Lung Volume Assessment
Body plethysmography accurately measures total lung capacity, residual volume, and other volumes for differentiating obstructive and restrictive lung diseases
Diffusion Capacity Testing
Evaluates how efficiently oxygen transfers from lungs to bloodstream, essential for assessing gas exchange disorders
Bronchodilator Responsiveness
Determines reversibility of airway obstruction to guide medication selection and treatment planning
What to Expect During Your Pulmonary Function Test
Pulmonary function testing at Dr. Raju's Sleep Centre & Multispeciality Hospital in Chandanagar, Hyderabad is painless, non-invasive, and typically takes 30 to 60 minutes depending on the tests performed. You will be seated or standing, and a qualified technician will explain each test before you begin. For spirometry, you will breathe into a mouthpiece connected to the PFT machine, taking deep breaths and exhaling forcefully. A nose clip ensures all air passes through the mouthpiece. The test may be repeated several times to ensure accurate results. For body plethysmography, you will sit inside a clear, comfortable booth and breathe through a mouthpiece while pressure changes are measured. Dr. Raju CH reviews all results personally and discusses findings with you during a follow-up consultation.
Benefits of Pulmonary Function Testing
Early and accurate diagnosis of respiratory conditions through pulmonary function testing offers numerous benefits. It confirms or rules out suspected lung diseases, preventing unnecessary treatments. It establishes baseline lung function for monitoring disease progression or improvement. It helps Dr. Raju CH select appropriate medications and adjust dosages based on objective measurements. For patients with sleep disorders, PFT identifies respiratory conditions that may be contributing to sleep-disordered breathing, enabling comprehensive treatment planning. It also provides valuable information for pre-operative risk assessment and helps determine the need for supplemental oxygen. At our Hyderabad sleep centre, pulmonary function testing is an essential component of complete respiratory and sleep care.
Common Respiratory Conditions Diagnosed at Dr. Raju's Sleep Centre, Hyderabad
Pulmonary function testing is essential for diagnosing and managing a wide range of respiratory conditions. Asthma, a condition characterized by airway inflammation and reversible airflow obstruction, is commonly diagnosed through spirometry with bronchodilator responsiveness testing. Chronic Obstructive Pulmonary Disease (COPD), including emphysema and chronic bronchitis, is identified by persistent airflow obstruction that does not fully reverse with bronchodilators. Restrictive lung diseases, such as pulmonary fibrosis or scoliosis, reduce lung volumes and are identified through lung volume measurement. Other conditions evaluated through PFT include bronchiectasis, vocal cord dysfunction, and respiratory muscle weakness. Dr. Raju CH, with 18 years of experience in pulmonary medicine, provides expert interpretation of PFT results and develops personalized treatment plans for each condition.
“Your lungs are the foundation of restful sleep. At Dr. Raju's Sleep Centre & Multispeciality Hospital in Hyderabad, pulmonary function testing helps us understand exactly how well your respiratory system is working, enabling precise diagnosis and targeted treatment for conditions that affect both your breathing and your sleep.” – Dr. Raju CH, Pulmonologist & Sleep Specialist
Preparing for Your Pulmonary Function Test at Dr. Raju's Sleep Centre & Multispeciality Hospital, Chandanagar, Hyderabad
Proper preparation ensures accurate pulmonary function test results. Dr. Raju CH will provide specific instructions based on your medications and health status. Generally, you should avoid heavy meals for several hours before testing, as a full stomach can restrict breathing. Avoid smoking, alcohol, and caffeine on the day of the test, as these can affect airway function. Wear loose, comfortable clothing that allows deep breathing. If you use bronchodilator medications, Dr. Raju will advise whether to take them before testing. Inform our Hyderabad sleep centre team of any recent respiratory infections or other illnesses. The test is painless and requires only your cooperation to perform the breathing maneuvers as instructed.
Pulmonary Function Testing for Sleep Apnea Patients at Dr. Raju's Sleep Centre, Hyderabad
For patients diagnosed with sleep apnea, pulmonary function testing provides valuable information that guides treatment. Obesity, common in sleep apnea patients, can affect lung volumes and respiratory mechanics. PFT helps Dr. Raju CH assess the impact of obesity on lung function and determine appropriate CPAP pressure settings. In patients with overlapping conditions such as COPD and sleep apnea (overlap syndrome), PFT is essential for distinguishing between the contributions of each condition to respiratory symptoms. For patients already on CPAP therapy, baseline pulmonary function helps monitor treatment response and identify any residual respiratory impairment. At our Chandanagar, Hyderabad sleep centre, Dr. Raju CH integrates pulmonary function results with sleep study findings to provide comprehensive, coordinated care for patients with complex respiratory and sleep disorders.
“Respiratory health and sleep health are two sides of the same coin. With advanced pulmonary function testing at Dr. Raju's Sleep Centre & Multispeciality Hospital, we evaluate both comprehensively, ensuring that every patient receives the complete diagnostic picture needed for effective, lasting treatment.” – Dr. Raju CH, Pulmonologist & Sleep Specialist
