Comparative Effects of ACBT and Slow Expiration in Patients With Chronic Obstructive Pulmonary Disease

"The participants in group A will be given ACBT with conventional chest physiotherapy .~Instruction for patient~* Try to keep your chest~* Take a long, slow and deep breath in, through your nose if you can.~* At the end of the breath in, hold the air in your lungs for 2-3 seconds before breathing~* Breathe out gently and relaxed, like a sigh. Don't force the air out.~* Repeat 3 - 5 times.~* If the patient feels light-headed then it is important that they revert back to the breathing control phase of the cycle~* Huffing"

The participants in group B will be given slow expiration with open glottis in lateral posture and conventional chest physiotherapy .In this technique, a patient adopts a lateral posture or a lateral decubitus posture. The affected lung is in the dependent position. A patient commences breathing normally, at tidal volumes. They are then instructed to perform a series of slow expirations with an open glottis. Expiration from functional residual capacity to the end of the expiratory reserve volume are encouraged to achieve maximum inflation . To assist in maintaining an open glottis, a mouthpiece may be used, to decrease the degree of airway compression A series of three ELTGOL may be performed, with each series composed of approximately 10 slow and deep expirations. In between each series of maneuvers, a rest period (around 1-2 minutes) is provided, with the patient staying in the same position. A typical treatment lasts for around 20 minutes
