Cardiorespiratory Physiotherapy Questions and Graded Answers, 100%
Guarantee
How does physiotherapy improve secretion movement? - Increase in expiratory flow
Use of gravity
Change of rheology
Possible increase of cilia beat (exercise!)
Increasing overall lung volumes
List 2PGLF types. - Annular flow
Mist flow
What is annular flow? - Annular flow is when PEFR > 10% of PIFR.
Needs excessive secretions, but high air flow causes waves in secretions moving them towards
the mouth.
What is mist flow? - Mist flow is maximal expiratory flow. Generally occurs in a narrows
airway (dynamic compression!)
Describe cough - Cough is inhalation of air (increasing intrathoracic pressure), glottis
closure (still increasing intrathoracic pressure), forceful contraction of abdominal muscles and
diaphragm (still increasing). As the glottis reopens there is dynamic compression of the airway
resulting in supramaximal flow of air --> mist flow = getting rid of a lot of secretions!
Describe huff - Forced expiratory technique while the glottis is open. Uses annular flow to
clear secretions.
Two typesL Huff from high volume and huff from low volume.
