What is tidal volume?
Volume inspired or expired with each breath at rest
What is inspiratory reserve volume?
Maximum volume that can be inspired at the end of tidal inspiration
How do you measure inspiratory capacity?
Tidal volume + Inspiratory Reserve Volume
What is expiratory reserve volume?
The max volume of air that can be expired at the end of normal tidal expiration
What is residual volume?
Volume of air remaining after maximum expiration
How do you calculate residual volume?
Functional residual capacity - Expiratory Reserve Volume
What is functional residual volume?
Volume in lungs at the end-expiratory position
How do you calculate functional residual volume?
Residual volume + Expiratory Reserve volume
What is vital capacity?
Max volume of air that can be expired after maximum inspiration
How do you calculate vital capacity?
Inspiratory capacity + ERV
What is total lung capacity?
VC + RV
What is the management guidance of COPD?
1) SABA/SAMA
2) If asthmatic features: LABA + ICS and if still no response LABA + LAMA + ICS (if on a SAMA, switch to SABA)
3) If no asthmatic features: add LABA + LAMA (switch SAMA to SABA)
