When your kidneys sense a low blood oxygen level the adrenal gland secretes erythropoietin. This signals the bone marrow to synthesize more red blood cells. Also commonly known as EPO.
a decrease in oxygen will result with an increase of red blood cell production (more carriers for hemoglobin to compensate for the lower levels of oxygen). The kidneys produce erythropoietin that stimulate RBC production.
I believe it causes the kidneys to secrete more erthyropoietin, a hormone that stimulates the synthesis of red blood cells in bone marrow.

An increase in oxygen levels
The correct name for low levels of oxygen in the blood is hypoxaemia. Low levels of oxygen in the body tissues is called hypoxia
If this process is inadequate, oxygen levels in the blood decrease, and the patient may need supplemental oxygen.
Breathing speeds up, but the breaths are shallower.
Erythropoetin from the mesangial cells of the glomerulus in the nephron of the kidney. These cells detect altered levels of oxygen in the blood plasma.
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.
Primarily it is the cabon dioxide levels that trigger respiratory drive, however in some disease states such as COPD increased oxygen levels can decrease respiratory drive.
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
