Diaphragmatic breathing technique will be the baseline treatment. B group will be treated with bubble positive expiratory pressure device. Patients will be encouraged to blow down the tubing into the water, and make bubbles. This creates positive pressure back up the tubing and into patient's airways and lungs. As the pressure holds open your patient's airways, it helps more air to move in and out of their lungs. All study participant will receive a total of 18 treatment sessions over a six-week period, which consisted of 03 treatment sessions per week.

Diaphragmatic breathing technique will be the baseline treatment.A group will be treated with active cycle breathing technique. The technique consists of inspiratory hold technique, deep breathing and forced expiration. These are repeated in a cycle until your chest feels clear. You can carry out ACBT when either sitting or lying down.

Physiotherapist will discuss this with you during your physiotherapy assessment. All study participant will receive a total of 18 treatment sessions over a six-week period, which consisted of 03 treatment sessions per week.

This study will be Randomized Clinical trial, Subject diagnosed with asthma meeting predetermined inclusion and exclusion criteria and will be divided into two groups. The baseline treatment for both groups would be diaphragmatic breathing exercises. While group A will be treated with ACBT. Each subject will receive 18 sessions with 3 treatments per week. Post treatment values will be recorded after the session and recorded values will be analyzed using SPSS 25.

Dyspnea 12 is a valid and reliable measure of breathlessness in patients. It measures the current level of a patients breathlessness severity, incorporating both physical and affective aspects and does not depend on activity limitation. D-12 consists of 12 descriptor items on a scale of none (0), mild (1), moderate (2), or severe (3). It provides an overall score for breathlessness severity that incorporates seven physical items and five affective items. The time reference period captures the current level of breathlessness experienced by patients as opposed to specifically on the day of the test or in response to a specific activity. Data will be calculated before and after treatment with the help of outcome measure tools.

The breathlessness, cough and sputum scale (BCSS) is used to predict patient exacerbation by evaluating common symptoms. The BCSS tool measures the patients self reported symptoms in real time. BCSS is a patient-reported outcome measure that asks patients to rate the severity of the three symptoms, each on a 5-point scale; from 0 to 4 the higher scores indicate more severe symptoms. Item scores are summed to yield a total score. Data will be calculated before and after treatment with the help of outcome measure tools.

Pulmonary function tests measure how much air you can exhale, and how quickly. There are several types of pulmonary function graphs that show data from the tests. The test which will be used is FEV1/FVC. This is the amount of air exhaled in the first second, compared with the total amount of air exhaled. It's given as a fraction (ratio) or a percentage. In general, the higher the FEV1/FVC, the better. This test will be done using Spirometer. Data will be calculated before and after treatment with the help of outcome measure tools.
