Pulmonary Function Test

Pulmonary function test (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Pulmonary function testing has diagnostic and therapeutic roles and helps clinicians answer some general questions about patients with lung disease.

PFTs are normally performed by a physiotherapist and GP Pulmonary function testing is a diagnostic and management tool used for a variety of reasons, such as:

Bronchoscopy is a procedure that allows your doctor to look at the trachea (windpipe), the bronchi (branches of the airways) and into some areas of the lungs through a thin, long, flexible tube, about the width of a thin pencil called a bronchoscope. The tip of the endoscope has a small camera with light source, which transmits the image to a video monitor. During the bronchoscopy, a bronchoscope is passed up through your nose or mouth, past your larynx (voice box) down your trachea and into the bronchi. The doctor will take some samples of any mucus or other secretions found in the airways for laboratories for analysis. Sometimes it is required to take a biopsy (small piece of tissue) of lung (TBLB) or airways (EBB) or needle aspiration of glands in chest (TBNA) which is sent to the laboratory for analysis. This is done by passing small instruments called forceps or needle through the bronchoscope.


Thoracoscopy is a medical procedure involving internal examination, biopsy, and/or resection of disease or masses within the pleural cavity and thoracic cavity. Thoracoscopy may be performed either under general anaesthesia or under sedation with local anaesthetic.



Cryoprobe or Cold probe is a technology where the probe coil and/or built-in signal preamplifier are cooled with a stream of He gas at ~20K. This increases the sensitivity of the probe coil and reduces the level of thermal noise generated by electronic circuits and components of the signal receiver itself.

The result is that the signal to noise ratio can increase by about 4X vs. a room temperature probe. In principle experiments can be run in 1/16 the amount of time as on a conventional probe, all else being equal. Or experiments can be run on samples with 1/4 the concentration in the same amount of time as on a conventional probe.

Flexible Bronchoscopy

Flexible bronchoscopy is used to examine the Airways of the lungs. This procedure is used for two purposes: to find out about a health issue, or in treatment of a known pre-existing health issue.
