Pulmonology & Chest Medicine Home About Us Our Hospital Our Technology Pulmonology & Chest Medicine Overview The Pulmonology & Chest Medicine Department at Sir H. N. Reliance Foundation Hospital utilize advanced diagnostic technologies to deliver a deeper, more accurate understanding of respiratory health. Our use of non-invasive lung function assessment tools, like those measuring airway resistance and reactance, allows for early detection and precise monitoring of conditions such as asthma, COPD, and other chronic lung diseases—even in patients who struggle with traditional breathing tests. This level of detail ensures tailored treatment plans, improving both clinical outcomes and patient quality of life.We also specialize in the comprehensive evaluation of sleep-related breathing disorders. With high-resolution polysomnography, we can diagnose conditions like obstructive sleep apnea and other nocturnal respiratory disturbances with exceptional accuracy. For patients, this means targeted, effective treatments that restore restful sleep and overall health. Polysomnography Impulse Oscillometry System Polysomnography—or sleep study—is a non-invasive test for diagnosing various sleep disorders, such as sleep apnoea or other sleep-related breathing disorders, in which breathing stops and starts repeatedly during sleep. This test involves monitoring a variety of body functions—blood oxygen levels, brain waves, heart rate, breathing, and leg and eye movements—in the sleep mode. Additionally, a sleep study might help determine a treatment plan and adjust treatment after diagnosis.Philips Respironics Alice 6 LDxN 68-Channel Full PolysomnographThis state-of-the-art solution for sleep studies and diagnostics offers comprehensive monitoring capabilities, which include electroencephalography (EEG), electrocardiography (ECG), and respiratory parameter analysis, ensuring accurate assessment of sleep disorders and management. The equipment with its advanced features provides clinicians with detailed data for precise diagnosis and treatment planning. The equipment includes an extensive array of measurement sensors and capabilities to provide a complete and precise assessment of an individual’s sleep patterns and overall The Impulse Oscillometry System (IOS) provides clinically relevant information regarding disease-introduced alterations in chest mechanics by performing a detailed analysis of tidal breathing; in a sense, it is complementary to spirometry, a test that measures lung volume and airflow.Thus, IOS is an informative and meaningful tool for the early detection and follow-up of lung diseases (for e.g., chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, emphysema, bronchitis, and asthma). Importantly, IOS does not usually cause discomfort to patients and thus, circumvents any issues associated with patient cooperation; further, it can be used to test patients from a wider range of age groups than spirometry (suitable for children, adults, and even elderly patients). Some key features of the IOS system are:Ability to investigate airway function under quiet breathing conditions.Compatibility with children aged less than 5 years.Capability to sensitively detect pulmonary obstruction in the early stages.Ability to distinguish between central and peripheral airways through measurement of airway reactance and resistance at multiple oscillatory pressure wave frequencies.Ability to detect the response to drug therapy with greater sensitivity than the commonly used forced expiratory volume in 1 second (FEV1) method.Ability to monitor bronchial provocation.Ability to classify small airway dysfunction according to severity, thereby enabling early detection of respiratory disorders.
