Advance Pulmonary Function Test

 Advance Pulmonary Function Test

ATS/ERS statement 2005 recommends performing Spirometry, Body Plelthysmography and DLCO(TLCO) for proper lung function testing of a patient with unexplained breathlessness. Pulmonary function tests (PFTs) are non-invasive diagnostic tests that provide measurable feedback about the function of the lungs, by assessing lung volumes, capacities, rates of flow, and gas exchange and severity of lung impairment. Bronchial Challenge Testing helps in diagnosing or ruling out Asthma in several patients with unconfirmed Spirometry. Simple 6 minute walk test are a good measure of overall exercise capacity of the patient. IOS has huge application in pediatric population where conventional Spirometry is avoided and may be time consuming. CRF has the capacity to perform all these tests with standards exceeding global recommendations. CRF aims to make all the doctors well acquainted with the performance and interpretation of these tests and provides training through the APFT workshop.

The workshop begins with the lecture on the basics of lung physiology covering following concepts: resistance, compliance, small and large airways, alveolar attachments, histo-pathology in asthma and COPD, lung volumes, role of bronchial hyper responsiveness and physiology of hyperinflation and air-trapping.

Body Plethysmography

Body plethysmography measures lung volume parameters like FRC, RV, TLC which, spirometry is unable to measure. It also measures sensitive parameters like airway resistance, airway conductance and intestinal gas.

Impulse Oscillometry (IOS)

IOS is an advanced lung function test which helps in early diagnosis of lung disorders. It provides valuable information required for differentiation of ventilation disorders. IOS is non-invasive, very easy to perform and requires minimal patient cooperation. IOS can be used in wide patient spectrum, from children to geriatric subjects. IOS helps in understanding mechanical properties of the respiratory system by applying an oscillating flow (pressure waves of different frequencies 3 to 35Hz) to the respiratory system and then measuring the resulting pressure response.


In this technique diffusing capacity of the lungs is measured using carbon monoxide (CO). DLCO also known as TLCO transfer factor of the lung for carbon monoxide (CO) is the extent to which oxygen passes from the air sacs of the lungs into the blood. DLCO is decreased in any condition which affects the effective alveolar surface area, cardiac diseases like right-left shunt, pulmonary edema etc. DLCO is a sensitive measure of pulmonary gas exchange and is useful to distinguish between intrinsic lung disease and loss of lung tissue.

Sputum Induction & Cytology

Sputum induction is a non invasive, simple, cost effective and safe procedure to collect respiratory secretions from lung airways to assess airway inflammation in asthma and COPD.

Bronchial Challenge Test

The bronchial provocation test evaluates how sensitive the airways in your lungs are and a spray called methacholine can be inhaled. Challenge tests may be performed in patients with symptoms of bronchospasm who have normal pulmonary function studies or uncertain results of bronchodialtors studies

The entire training program involves sessions on basics with indications of the tests along with procedural details, quality assurance and report interpreting skills with its clinical evaluation. This is followed by a detailed hand on practical session where the delegate can train on performing the tests, getting the test performed and understanding the interpretation of the performed tests.


Spirotech is an interactive course that provides both presentation and hands on training which helps understand the international guidelines that underpin the performance of quality spirometry, and develop both skills and confidence in maintaining and using the spirometer by the paramedical staff or a technician

Spirometry Simplified

Spirometry is made easy in this simple one day interactive course for the practicing physicians. Here you get to learn the basics of spirometry along with details on performing, assessing the quality and interpretation of Spirometry.

Spirometry E-learning Module

This is a three and half hour module which covers spirometry in detail. You can avail of this facility online anywhere in the world. The delegate needs to complete an assessment test at the end of the module in which certificate of completion is awarded after achieving minimum of 80% score.
