Pulse oximetry uses a device called a pulse oximeter to measure the oxygen saturation in your red blood cells. The device will display your blood oxygen levels as a percentage. People who have lung issues such as chronic obstructive pulmonary disease (COPD), asthma, or pneumonia or people who temporarily stop breathing during sleep (sleep apnea
Oxygen saturation. Oxygen saturation measures how much hemoglobin is currently bound to oxygen. Each gram of hemoglobin is capable of carrying 1.36 mL of oxygen. The solubility coefficient of oxygen in plasma is 0.003. This coefficient represents the volume of oxygen in mL that will dissolve in 100 mL of plasma, for each 1 mmHg increment in the
Oxygen delivery is the product of the cardiac output and arterial oxygen content. Cardiac output is determined by the preload, afterload, and contractility. The arterial oxygen content is the sum of oxygen bonded to hemoglobin and dissolved in plasma, approximately 1.34 mL per 1 g of hemoglobin and 0.003 mL of oxygen per 100 mL of plasma.

The Zacurate fingertip pulse oximeter blood oxygen saturation monitor is a great choice for monitoring your blood oxygen saturation levels. The device is designed to be easy to use and provides accurate readings in just seconds. The oxygen saturation monitor comes complete with a lanyard and batteries, so you can start using it right away.
ScV0 2 is a good and more practical surrogate for SvO 2. If you begin with 100% arterial oxygen saturation and end up with a 75% venous oxygen saturation (ScV0 2 ), then oxygen consumption or “oxygen extraction” was 25%. Normal range of oxygen extraction = 25-30%, corresponding to a ScV0 2 > 70%.
A typical blood oxygen level for a healthy person ranges between 95% and 100%. This means that nearly all of the red blood cells are carrying oxygen to your cells and tissues.
