OXYGEN DEBT 



A temporary phenomenon that occurs in an 

 organism when available oxygen is inadequate 

 to supply the respiratory demand. During 

 such a period the metabolic processes result 

 in the accumulation of breakdown products that 

 are not oxidized until sufficient oxygen 

 becomes available. 



OXYGEN DEFICIT 



The difference between observed oxygen 

 concentration and the amount that would 

 theoretically be present at 100% saturation 

 for existing conditions of temperature and 

 pressure.
