Describe the respiratory changes during pregnancy.
This question was variably answered, with a wide range of marks. Candidates often
mentioned central regulation, anatomy, respiratory mechanics, static lung volumes or gas
transfer, but did not provide comprehensive cover of all areas. Very few clearly described the extent of any change (either as a percentage or actual amount relative to the non-pregnant
state). A number of candidates presented information well in diagrammatic form (e.g. static
lung volumes) however then repeated this same information in text, which was unnecessary.
