Oxygen saturation (medicine) Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.n medicine, oxygen saturation (SO 2), commonly referred to as sats, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated.

- Normal Findings. If 97 percent of your hemoglobin contains oxygen, your blood oxygen saturation is at maximum capacity, UTMB reports. Normal results on a pulse oximetry reading range between 96 and 100 percent of this maximum value.If your pulse oximetry readings fall below 90 percent of maximum, you enter a clinical state called respiratory failure, characterized by inadequate oxygen supplies to your vital organs and body tissue.f your pulse oximetry readings fall below 90 percent of maximum, you enter a clinical state called respiratory failure, characterized by inadequate oxygen supplies to your vital organs and body tissue.

What Are the Normal Oxygen Levels in Humans? Quick Answer. Mayo Clinic defines the normal human oxygen level as 95 percent to 100 percent. Levels below 90 percent are considered low. Oxygen levels are usually measured with a pulse oximeter device attached to the finger; this device measures the amount of oxygen saturating the blood. Continue Reading.

- Normal Ranges. Oxygen saturation level in healthy patients is considered normal between 97 percent and 99 percent. Patients who have normal hemoglobin levels can have a saturation level of 95. When the amount of oxygen in the blood is reduced, a condition known as hypoxemia results, and treatment is then required.

Hypoxemia: Definition, Causes, and Treatment During hypoxemia, the oxygen saturation in the body is less than 90 percent. This is the formal definition of hypoxemia. Normal pulse oximeter readings can range from 95 to 100 percent. If the same falls below 80 percent, the condition is referred to as severe hypoxemia. Hypoxemia has a profound negative effect on quality of life (Nonoyama et al, 2007; Orth et al, 2008; Sans-Torres et al, 1999; Tanni et al, 2007). Even nocturnal hypoxemia (i.e., temporary hemoglobin desaturation during sleep) has negative effects on life quality (Young et al, 2011).

- The normal respiration rate for an adult person at rest, as stated in the University of Virginia's Health System website, is from 15 to 20 breaths per minute. Respiration rates of more than 25 breaths per minute or under 12 breaths per minute (when at rest) may be considered abnormal.

If the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.

- Employee Notice Requirements. The main employee notice requirement under the FMLA is that employees must inform employers of their need to take FMLA leave. The timing of this notice depends on the circumstances: When the employee's need for leave is foreseeable, the employee must generally give at least 30 days' notice.

Normal Range of Blood Oxygen Level This measurement is called an arterial blood oxygen. A normal arterial blood oxygen level typically falls between 75 and 100 mmHg. Your blood carbon dioxide level and pH -- a measure of acidity or alkalinity -- are usually measured along with the arterial blood oxygen level. pulse oximeter uses light to measure the oxygen saturation level, the percentage of hemoglobin in your red blood cells carrying oxygen. Normal oxygen saturation levels fall between 95 and 99 percent.

Top 20 Doctor insights on: Alprazolam Blood Level It depends: If you live at sea level, and the pulse oximetry machine if functioning normally, your arterial oxygen saturation should be higher than 93%. If you live at high altitude, the partial pressure of oxygen in the air is lower and, depending on how high you are, an oxygen saturation level of 93% may be normal.

- Normal Pulse Oximetry Readings. Normal blood oxygen saturation readings at or near sea level is between 95 to 100 percent, as measured by the pulse oximeter. Normal arterial blood flow and calculated heart rate depend on the state and age of the patient (such as newborn or unconscious adult).ypoxia. When the body or tissues are deprived of oxygen, it is in a state of hypoxia. Pulse oximeters are accurate in the critical range of 70 and 100 percent, which alerts physicians to critical states before symptoms can arise.

What Is a Normal Oxygen Level for an Adult Female? Normally, when your blood circulates to your lungs, 95 to 100 percent of your red blood cells are able to grab oxygen molecules, reports Harvard Health Publications. This is the normal oxygen level for an adult female and can be measured using a device known as a pulse oximeter.This is a small instrument that attaches to one of your fingers and is able to measure the amount of oxygen inside your blood in a non-invasive manner.xygen Saturation. The term oxygen saturation refers to the amount of oxygen your blood is carrying. When your blood circulates, it goes to each of your cells and picks up carbon dioxide, a byproduct of metabolism.

Oxygen Saturation Monitoring If she has a heart condition that prevents the red blood cells (specifically hemoglobin) from picking up oxygen, her saturation level will be lower. This reduced amount of oxygen in the blood is called hypoxemia or cyanosis​ . People breathing regular air have a saturation of 96% to 98%; anything less than 95% results in hypoxemia, which is cause for concern.

- 1.An Arterial Blood Gas (ABG) Level of 55mmHg or below. 2.Oxygen Saturation level of 88% or below at rest or during exercise. 3.Oxygen Saturation level of 88% or below during sleep for greater than 5 minutes. A patient may have an ABG of 56 to 59 mmHg or an oxygen saturation level of 89% and qualify for 90 days if they have corresponding dependent edema suggesting Congestive Heart Failure, P Pulmonale on EKG, and Polycythemia with HCT >57%. The patient must requalify in 60 to 90 days for continued oxygen qualification. For all the above, the patient must be in a chronic stable state. If patient is out patient at time of oximetry, the results are good for 30 days following date of test.

Normal Range of Blood Oxygen Level Newly oxygenated red blood cells carry oxygen to your body. A pulse oximeter uses light to measure the oxygen saturation level, the percentage of hemoglobin in your red blood cells carrying oxygen. Normal oxygen saturation levels fall between 95 and 99 percent.f you're in good health, normal blood oxygen levels almost always fall within a very predictable range. Medical professionals use two primary measurements for determining your blood oxygen level: oxygen saturation and arterial oxygen. The normal values differ for these measurements.
