Gordon Drummond of Edinburgh contacted us regarding the article on Pharmacokinetics and Anaesthesia by Fred Roberts and Dan Freshwater-Turner (CEACCP 2007; 7(1): 25–29). He was unhappy with the assertion that an inhaled drug...crosses the alveolar membrane into the blood along its partial pressure gradient. This produces an exponential wash-in.... Dr Drummond writes that This suggests that the exponential wash-in is caused by a partial pressure gradient. This is not so. Volatile anaesthetics are believed by almost all to equilibrate rapidly and virtually fully, between alveolar gas and alveolar capillary blood, and
