You eat at chips and salsa at Qdoba. All that salt causes your cells to lose water through osmosis. Your hypothalamus senses that your cells are shrinking
and sends a message to the
pituitary to release antidiuretic hormone. ADH sends a message to the kidneys to stop
releasing water in the urine. You also start to feel thirsty. The result is that your cell's water
level increases back to normal. This is an example of

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
