Arterial blood gases - oximetry

What is arterial blood gas examination? Is a test that allows us:

(a) to see if the patient is hypoxia (low oxygen levels in the blood) or is in respiratory failure or not this kind.

(b) monitoring the improvement or not during treatment

How is this examination?

Using an insulin syringe (after being iparinisthei, to prevent blood clotting), typically receive arterial blood from the radial artery harvesting located on the wrist or the brachial artery and into a special machine (gas analyzer). The main parameters, among many, which are measured are:

* Oxygen
* Carbon dioxide
* PH (a parameter which indicates whether there is acidosis or alkalosis)

What is oximetry?

The examination is done with the oximeter, as shown in the picture.
