So, your PaCO2 is, oh say 150mmHg.  So what. What could go wrong?

Consequences of Respiratory Acid-Base Disorders

Interestingly, none of this has ever made it into the fellowship paper. One might suppose that such fundamental concepts are better interrogated in the primary exam. For those who were for whatever reason exempted from this great barrier, apocryphal pages are available in the section concerned with acid-base disturbances. Specific chapters offer detailed digressions regarding physiological effects of carbon dioxide, buffering in acute respiratory acid-base disturbances  and the physiology of carbon dioxide storage and transport.
