There are a number of them: the Pulse Oximeter- requiresa pulse so is placed on an artery. It uses red and infrared light to measure the colour of the blood. If blood is oxygenated it is bright red and absorbs/reflects light differently to darker blood which is deoxygenated. Benarons monitor is similar to pulse oximeter but uses shorter light (blue and green). This is used to monitor capillaries and does not require a pulse hence is suitable when perforning things like bypass surgey.
oxygen is measured in the blood by a method called pulse oximetry , a probe is attached to the patients finger or the earlobe in case of a child
the probe has a ultroviolet light which passes from one side to the other and it senses the change in wavelength when it hits the red blood cells which are moving in our cappilaries , a tracing can be seen on the monitor screen and a value will also be given on the screen
this can give an idea about the oxygen levels in the blood
a more accurate method is to puncture the artery , radial artery at the wrist or the femoral artery at the thigh is used most commonly and the blood sample is put into the machine which is called the arterial blood gas machine , it will given an accurate reading of the oxygen levels as well as the saturation of the patient , that is the amount of hemoglobin which contain oxygen
the normal saturation of an adult breathing room air should be above 95 - 96 %
with a pulse oximeter. it is a device (usually fitting the index finger) to measure the oxygen saturation in blood.

Our blood need to carry oxgen so it can help us in combustion
The blood gives up Carbon Dioxide in the left Ventricle and it obtains oxgen when the blood is returned from the lungs and to the right ventricle to the rest of the body.

Add a liquid to the blood that can't be transported out of the lining of the blood vessels. Give it time to spread through the body. Then, take a blood sample and measure the percentage of the liquid in the blood. From the result, the blood volume can be estimated. total blood volume = ((1 - percentage)/percentage) x amount of liquid added
a job is to carry oxgen to your haert where the heart pumps. we need blood becase it carrys oxgen to the haert

Yes
blood brings oxgen and nutrients to cells
The red blood cells carry oxygen on hemoglobin.
it carry nutrients,sugar,and oxgen

true
Arteries carry oxygenated(oxygen rich blood) and veins carry deoxygenated blood. But pulmonary artery carry deoxygenated blood and pulmonary vein carry oxygenated blood.
The blood gives up Carbon Dioxide in the left Ventricle and it obtains oxgen when the blood is returned from the lungs and to the right ventricle to the rest of the body.
White blood cells fight against diseases and infections in the body. They are the first line on defense. Red blood cells carry oxygen within the body.
