Oxygen desaturation during oesophageal manometry.
Eighteen generally fit clinical patients were monitored with pulse oximetry. Mean oxygen saturation levels were lower (P<0.05) during oesophageal manometry (97.7-97.3%) than before it (98.3%). Fourteen out of seventeen (successful) traces had short 4-8% desaturation episodes, and in worst cases there were 8-9 episodes. It seems, therefore, that even patients with no predisposing factors than perhaps smoking and mild bronchial asthma are vulnerable to some oxygen desaturation in oesophageal manometry.
