RESPIRATORY PHYSIOTHERAPY EXAM REVISION. ALL EXAM

REVISION QUESTIONS AND CORRECT ANSWERS (ALREADY

GRADED A+) (2024 UPDATE) 100% GUARANTEED

Why does emphysema cause a barrel chest - ANSWER- increased AP dimensions - inspiration

is normal initially but tidal expiration effected so with every inspiration, expiration isn't complete,

leading to hyper inflation


What is the difference between a 'pink puffer' and a 'blue bloater' - ANSWER- pink puffer =

increased reliance on accessory muscles

Blue bloater = respiratory centre relaxes leading to low oxygen saturation and cyanosis appearance


What is the purpose of serus fluid - ANSWER- allow lungs to glide over thoracic wall during

breathing


What keeps pleura together - ANSWER- high surface tension - advantageous as when chest

expands, lungs do as well


Is intra-pulmonary pressure normally positive or negative - ANSWER- negative


In what part of the thoracic cavity is the heart and major vessels found - ANSWER-

mediastinum


Pulmonary ventilation = - ANSWER- inspiration + expiration


Another term for intra pulmonary pressure - ANSWER- intra alveolar pressure

,What does intra pleural pressure oscillate between - ANSWER- -7 mmhg on inspiration and -

4mmhg on expiration


What does Boyles law state - ANSWER- when temperature is constant, the pressure of a gas

varies inversely with its volume


What is closing volume - ANSWER- the volume of lung inflated when small airways in the

dependant part of the lung begin to collapse during expiration. I an healthy individual, closing

volume is < FRC


What happens if FRC falls below closing volume - ANSWER- a reduction is FRC predispose

patients to atelectasis and if closing capacity > FRC the alveoli collapse during expiration (normal

tidal breathing) trapping air and precipitating atelectasis


Causes of low lung volumes/altelectasis (post surgery) - ANSWER- abodominal or thoracic

surgery, where it occurs mainly as a result of pain and inhibition of diaphragm, causing shallow

breathing. (other causes include, consolidation, airway obstruction, age and respiratory muscle

dysfunction)


Why is atelectasis worse in an obese patient - ANSWER- fat prevents adequate lung expansion

by squishing the thorax. V/Q mismatch also occurs


Why is atelectasis worse in an elderly patient - ANSWER- inadequate lung expansion results

for elderly not having the strength to generate a strong and healthy breath. History of a respiratory

condition such as CF or COPD or Asthma may have damaged airway or mucus may obstruction

airway. Compliance is less in an elderly patient also.

, Name 1 internal (affects alveoli directly) cause of atelectasis - ANSWER- consolidation (most

frequently caused by lobar pneumonia)


Signs of low lung volumes - ANSWER- - poor lung expansion


- decreased tidal volume

- breathlessness

- increased work of breathing

- decreased exercise tolerance

- alveolar collapse

- decreased breath sounds

- sputum retention


What are the 4 types of atelectasis - ANSWER- - obstructive - foreign body (intrinsic) or

tumour (extrinsic)

- passive = shallow breathing

- compressive = pleural diseases

- adhesive = increased surface tension = presence of pus/fluid reduces surfactant coating


Inspiratory physiotherapy techniques - ANSWER- - sustained maximal inspirations with holds

and sniffs

- localisation of expansion to particular areas of lung

- positioning
