Bones, joints and muscles are greatly altered during pregnancy. Relaxing helps to soften the cartilage as well as the ligaments and thus makes the joints a little unstable. It also makes the joints prone to injury. These all result due to the changes in weight during pregnancy. Physiological and anatomical changes have a major effect during pregnancy and have the capacity to affect not only bones but  [...]

How to Use Pulse Oximeters for Determining Blood Oxygen Levels?

Submitted by on December 5, 2011 – 9:37 pmNo Comment




The blood oxygen levels reflect the quantity of oxygen our red blood cells is carrying to the different organs of our body. Lung disorders like COPD or chronic obstructive pulmonary diseases can result in decrease levels of oxygen in our blood. Patients with COPD require monitoring their blood oxygen levels at regular intervals. The oxygen levels in blood can be measured using pulse oximeters or the SPO2 monitors as well as by undergoing Arterial Blood Gas test at the doctor’s office. In this article, we will be discussing the process of using pulse oximeters of determining blood oxygen levels.

Using pulse oximeters for measuring levels of oxygen in blood involves the following step:

  1. Take the device and attach it to your finger’s end. You will see a light shining across the finger tip. Pulse oximeters determine the levels of oxygen in blood by using light. If the blood is fully oxygenated, acclainsetscasino the hemoglobin present in blood has bright red color. The color of hemoglobin turns purple or dark red as the level of oxygen in blood decreases.
  2. Check the level of oxygen in blood by monitoring the reading displayed on your pulse oximeter. In some pulse oximeters, the result is shown on the device and in some the result gets displayed on a meter attached to the device. A healthy individual should have blood oxygen levels between 95 to 100 percent.
  3. If the readings on the pulse oximeter reveal that your blood oxygen levels in below 95%, you must get yourself checked by your physician. Remember that the readings offered by pulse oximeters are only rough estimates of the levels of oxygen in your blood.  The doctor will never ask you to take medicines depending on the results obtained on this device. If the monitor shows that you blood oxygen levels in below 95%, the physician will ask you to undergo a, Arterial Blood Gas test or ABG test for obtaining the accurate reading.
