Q

Pathophysiology

A

chronic, relapsing, inflammatory disorder characterisd by hyper-reactive airways which leads to episdoes of reversible bronchospasm
typically caused by a trigger which results in an acute inflammatory response
- bronchoconstriction
- increased capillary permeability
- mucus gland hypertrophy and secretion

2
Q

Clinical Implications

A
airflow limitation 
impaired airway clerance 
impaired gas exchange 
dyspnoea 
reduced exercise tolerance
3
Q

Clinical Features

A

episodic symptoms

  • wheezing
  • chest tightness
  • breathlessness
  • potentially a productive cough
  • obstructive pattern in spirometry which is reversed with inhalation of bronchodilators
  • reduced peak expiratory flow
4
Q

Medical Management

A

Pharmacology - inhaled preventers and relievers
use spacer with inhaler
written asthma action plan
risk prevention - avoid triggers

5
Q

Physio Management

A
spirometry/PEF testing 
inhaler technique education 
reinforce the action plan 
airway clearance techniques 
positions for breathlessness
exercise
6
Q

Exercise Prescription

A

Frequency - at least 2-3 days per week
Intensity - at least 60% of VO2 peak
Time - 20-30 mins per day
Type - aerobic activities that target large muscle groups
Progression - increase to 70% of VO2 peak
- 40 mins per day
- 5 days per week
