Heres the actual question, i hope some one knows this stuff. Thanks in advance to any who reply..
Identify one instrument used by medical personnel to measure the oxygen saturation and one instrument used to measure caron dioxide concentration in the blood.
Hey...an actual answer for the question can be found
here
OR i'll just say it here:
Pulse Oximeters:
A sensor attached to the person measures the absorption of light by the blood. This is used to tell the concentrations of oxygen in the blood as blood with different levels are of a different colour.
Pulse oximetry is used to monitor the level of oxygen in a person's blood during heavy sedation or anesthesia. This device is also used when a person is on a ventilator, artificial breathing machine, during stress testing, in sleep laboratories, when checking the body's response to different medications or to monitor a person with asthma or who is having trouble breathing.
ABG:
Unlike the above method, ABG requires a sample of the blood to be obtained. An analysis machine measures O2 content and saturation as well as the bicarbonate content and related pH.
Its main use is for lung disease (pulmonology), for assessing the lungs ability to deliver oxygen and and get rid of CO2.
