Airway Clearance Techniques: Autogenic Drainage and PEP

Airway Clearance Therapy (ACT): ACT utilizes physical or mechanical methods to influence airflow, aiding in the expulsion of secretions from the trachea and bronchi, or triggering coughs to expel mucus. In previous lessons, we learned methods such as positional drainage, chest percussion, and active cycle breathing techniques. Today, we will learn about Autogenic Drainage and … Read more

Can Sputum Drain Itself?

Cough cough cough…….. I have taken various expectorants, is there any non-drug method to assist in sputum clearance? Of course, in addition to the active breathing cycle technique introduced last time, sputum can also be “autogenously drained”. Autogenic drainage (AD) is a airway clearance technique that utilizes different lung volumes for breathing to facilitate the … Read more
