Technology Used At Centre For Chest & Respiratory Diseases

The Centre offers full spectrum of healthcare services using the latest and most advanced technologies to facilitate faster and healthier recovery cycle. Some of the cutting-edge technologies available at the Centre are:

Endobronchial Ultrasound (EBUS) -  is a minimally invasive but highly effective procedure used to diagnose lung cancer, infections, and other diseases causing enlarged lymph nodes in the chest.

EBUS allows physicians to perform Fine Needle Aspiration Cytology (FNAC)  that is used to sample superficial masses from deep-seated thoracic lymph nodes and tumours. 

Video-assisted Flexible Bronchoscopy - It is a Flexible Bronchoscopy procedure that involves the use of an endoscope (bronchoscope) for Transbronchial Lung Biopsy (TBLB)/Transbronchial Needle Aspiration (TBNA)/foreign body removal/diagnostic and therapeutic interventions. The Pulmonologists advances the bronchoscope with a camera on its top, through the airways in each lung to diagnose the problem. The camera displays the images from inside the lung on a video screen, using which a doctor can perform several other interventional pulmonology procedures.

Rigid Bronchoscopy- It is specially designed for patients who are not amenable for Fibre Optic Bronchoscopy.  It is used for diagnostic and therapeutic purposes including tumour removal foreign body removal and stenting. 

Impulse Oscillometry (IOS) - IOS is a variant of forced oscillation technique that is used to take the passive measurement of lung mechanics and help the doctor know about the functioning of the lung. It is currently the most commonly performed lung test to diagnose Obstructive Airways Disease (OAD). It is also used to determine prognosis and help evaluate response to therapy. 

Bronchoscopic Electrocautery - It involves the use of various instruments such as Hot Forceps, Snare and Knife powered by cautery that passes through a bronchoscope in the lung and is used for diagnosing and treating endobronchial (within the airways) obstructive lesions such as benign tumours, tracheobronchial stenosis, lung cancers and subglottic stenosis.

Bronchoscopic Argon Plasma Coagulation (APC) - An application that involves the use of heat produced by argon gas to coagulate tissue near the tumour, without touching the tumour.

Bronchoscopic Cryotherapy- A procedure that involves the use of extreme sub-degree temperature to ablate/remove granulation tissue from stents or anastomoses, malignant airway tumours and treat a variety of benign disorders.

Bronchoscopic Thermoplastic - An interventional pulmonology procedure that is used to treat cases of severe asthma which can’t be controlled through medication. A doctor applies a heat probe to the walls of the airways, thereby destroying the smooth muscle layers whose constriction causes asthma symptoms.

Bronchoscopic Laser Ablation - An application used to remove trachea-bronchial tumours, trachea-bronchial stenosis, subglottic stenosis using a laser beam with a high degree of precision.

Tracheobronchial Stenting - This procedure involves the use of a stent that is placed inside the airway via bronchoscope to keep them open. The obstruction in the airways can be caused by cancers or benign diseases like tracheal, sub-glottic stenosis and trachea-oesophageal fistula. 

Pleural Aspiration - In this process, the fluid accumulated outside the lungs in the chest cavity is extracted out using a cannula/needle for therapeutic benefit or diagnosis of pleural diseases.

Pleurodesis - A procedure performed over people with the problem of recurrent pleural effusions (fluid around the lungs). A doctor will insert a small tube inside a chest cavity and spray a chemical around the lungs. Over time the inflamed lung lining (pleura) will stick tightly to the chest wall, thereby preventing fluid from re-accumulating around the lung.

Medical Thoracoscopy / Pleuroscopy - A procedure used to diagnose some conditions of the pleura (lining of the lung). The pleural space (inside the chest) is examined using thoracoscope/pleuroscope. It allows the viewing of the outside edges of the lung, which is not possible with bronchoscopy.

Non-Invasive Ventilation - Ventilation is used to support respiration. It is achieved by connecting a ventilator to an endotracheal tube that goes directly into the central airways from the mouth. 

BIPAP Therapy - Bilevel Positive Airway Pressure ( BIPAP)is a machine which comes with a motor that generates airflow at high pressure. The airflow is delivered to the patient through a face mask. This is a non-invasive ventilation therapy of delivering support to the patient by creating a positive pressure inside the airways. 

CPAP Therapy  - Continuous Positive Airway Pressure (CPAP) is the most common universally effective treatment for sleep apnoea. The process involves the use of a CPAP pump to prevent repetitive upper airway collapse. It applies a continuous flow of air to the airway and creates an air cushion in the throat in order to ensure normal respiration.

Multiple Sleep Latency Test (MSLT) - MSLT is also known as day nap study wherein the tests are performed to assess daytime sleepiness. It examines how quickly a patient can fall asleep during daytime in a quiet environment. MSLT is the standard tool used to diagnose idiopathic hypersomnia and narcolepsy.

Maintenance of Wakefulness Testing (MWT)  - These tests are done on a patient to determine the patient's ability to stay awake during the day. The tests indicate how well a patient is able to stay alert during daytime in a quiet environment.

Overnight Diagnostic Polysomnogram (PSG)/ Sleep Study - It is one of the most common types of sleep studies.It records various data during the study which include:

  • Brain waves
  • Oxygen level in the blood
  • Heart rate 
  • Breathing
  • Eye and leg movements 

The test result is known as polysomnogram and is primarily used to diagnose sleep apnoea, parasomnia and other sleeping disorders.
