Lung Function Tests The Classical Approach
Why test lung function ?
LFT’s in Animals vs Human beings
Inputs
Volume Flow Acceleration
Two - element model of the lung
Lung ‘supermodel’
“Lungs behaving badly”
Tidal Breathing LFT’s
Static vs Dynamic measurements
Flow
PPT Slide
Flow-Volume Loops
Tidal Volume: from flow
Ventilation
Transpulmonary pressure
Movement of tidal volume
Equation of motion
Dynamic compliance
Small airways when narrowed, decrease lung ‘compliance’
Resistance
Obstructive diseases
Other less reliable indices of obstruction
Requirements for sensors
FRC functional residual capacity
Oscillatory mechanics
