Anaes Vivas · Applied cardiovascular & respiratory physiology
Data viva — lung volumes and capacities
A Primary data viva — define each capacity as a sum of volumes; explain FRC's role and the CC/FRC relationship; predict the effect of anaesthesia, the supine position and age.

Prompt
A stacked-bar diagram shows the lung volumes (RV, ERV, TV, IRV) grouped into capacities (FRC, VC, TLC, IC). Express each capacity in terms of its volumes, and state how anaesthesia and position change the FRC and its relationship to closing capacity.
