Oxygen and Carbon Dioxide: Respiration Stimuli or Biochemical Markers of Changes in Blood pH?

Bula-Bula M, Lepira F, Mvuama N

CO2, PO2 and PH are breath stimuli. This documentary study, carried out in the resuscitation care unit of the Clinic University in Kinshasa, is based on analysis of the standard deviations of these differents stimuli as well as on the Henderson-Hasselbalch equation to evaluate the role of the three stimuli. The results of this study show that blood PH, because it’s values are much more centered on the average (CV=1,969), is the true stimulus. As a result, PaCO2 and PaO2 would only act as biochemical markers of variations in the latter.
