EVALUATING ANTI-ASTHMATIC EFFECT OF POLYHERBAL AYURVEDIC DRUG BHARANGYADI ON RESPIRATORY MECHANICS USING MATLAB

Asthma is one of the most prevalent chronic inflammatory lung diseases among children and adults. A lot of work had been done in various field (including both modern and Ayurvedic) on anti-asthmatic drugs to evaluate their action on lungs. The parameters chosen for assessing the properties of drug is mainly based on clinical improvement and improvement in pulmonary function test. These all method employed so far are indirect method for assessment of action of drug on lungs as change in pulmonary function may appear without any relevant change in lungs mechanics. In present study we assess the anti-asthmatic effect of drug directly on respiratory parameter by using MATLAB lung mechanics modeling. Administration of drug is equally distributed throughout lungs and produces significant increase in lung volume which is attributed to the decrease in airways resistance and increase in lung compliance.
