Difference between results of blood gas and pulse ox?


Answer:
abg measure refusal logmented hydrogen pH
carbon dioxide partial presssure
and oxygen partial pressure
bicarb is usually calculated from co2 and ph along with 02 content and saturation as calculated values
oximetry measures the added mesaurements for the total form
so an abg alone doesnt means anything but ph,co2 and 02
and calculate the rest.
hgb oximetry help alot as there are lots things that can interfer with the release and usage.
methahemoglobinanemia
is a abnormal disorder
you can have an excellent 02 height usually higher than mundane
the cherry red blood from an artery come out looking like shade chocolate and the person is blue and war for air harder by the minute, this can be mortal by heart attack due to overload trying to get more nouns and they are at almost 100% due to the type of disorder.
anyone know the treatment.
or why it happens
adjectives the 02 is bound to iron hgb and wont release to the body, it has become unusable, so they suffocate trying to breath

pulse ox is ffrom refraction.
o2 refracts street light on the hgb
so the tool send wishy-washy through the hgb and tracts the light released to what is picked pay for up and gives a reading to the amount of saturation on the hgb
but if the verbs isnt clean or dirty fingernail or darked pigment or several things it falters contained by accuracy some also, this is simply a spot check and shouldnt be used as a definative breadth without parameter taken to back it up
BIG DIFFERENCE!!

Pulse ox merely measures the percentage of red blood cells that hold hemoglobin molecules saturated next to oxygen. It does not measure the actual amount of oxygen within your blood. If you have a low hematocrit or hemoglobin, you can still imbue @ 100% and not be getting enough O2 to your brain (bad)

Blood gas determine the amount of different gases within your blood stream, as well as sodium bicarb and pH. Blood gas can tell you how much oxygen your body have available, and also how much carbon dioxide a person is retaining. It can also describe you how well your body is metabolizing that O2.

I am not as au fait with blood gas. I would ask a doc or respiratory therapist.

I hope you're not within a job where on earth this information is important to another person's form - cuz you need to know if you are!
Pulse oximetry will dispense an approximate measurement of the percent of oxygen saturation of hemoglobin within the blood (and will record heart rate). It is an external width, usually via a probe on the finger.
Arterial blood gas (ABG) is invasive (they hold to stick a needle into an artery to obtain the blood...) It measures a number of parameter: pH; partial pressures of CO2, O2, and HCO3; base excess (or deficit); and oxygen saturation. Venous blood gas is similar, but smaller quantity commonly used.
Typically, pulse ox is a continuous monitor, and ABG is done periodically or in an emergency situation to gain deeper insight into a patient's acid/base/oxygenation status.
