Hypoxia and Medicine

What are the effect and mechanisms of action of hypoxia on the respiratory movement?

1. your question is peculiar. hypoxia is a lack of oxygen. this has no direct effect on respiratory movement, if by movement you mean the chest wall moving back and forth with the regular breathing action. CO2 on the other hand can be a respiratory depressant. although it to does not affect movement it does accumulate in the blood, and sparing all the physiology the increase in CO2 will cause the number of breaths to decrease, so maybe that is what you mean by saying having an effect on respiratory movement. you sound like a first semester RT student.
2. Not really sure what your asking but gmillion is a little off. Their are receptor cells located in the aortic arch. These receptors detect both 02 and CO2. In a normal healthy individual waste in the form of CO2 is noted by these receptors and 'blown off' by exhaling and O2 is taken in in exchange. In a person who is a CO2 retainer they are used to such high levels of CO2 that their bodies change chemistry to note the lower levels of O2 or hypoxia to trigger respiration. There is also the argument between the difference of physical and cellular respiration. The former is the actual act of breathing and the latter if the exchange of O2 and CO2 which is a chemical change instead of a physical act. I hope that helps. I not please post further request.
