- 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.

Is My Blood Oxygen Level Normal? A pulse oximeter (pulse ox) is a noninvasive device that estimates the amount of oxygen in your blood. It does so by sending infrared light into capillaries in your finger, toe, or earlobe. Then it measures how much light is reflected off the gases. A reading indicates what percentage of your blood is saturated.

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.

How to Interpret Pulse Oximeter Readings SpO2 normal values. The best place to get the answer to this question is in your doctor's office. Your pulse oximetry normal values are dependent on your health condition, respiratory rate, percentage of oxygen in the air, activities you are performing, and other factors.Here are some general guidelines to understand oximeter readings.For a regular healthy person, the normal blood oxygen saturation level (SpO2) should be around 94% to 99%. For patients with mild respiratory diseases, the SpO2 should be 90% or above.ere are some general guidelines to understand oximeter readings.

Normal Hemoglobin Levels However, the National Institutes of Health offers the following general, accepted range for normal hemoglobin levels in children and adults: Normal range for adults: Male: 13.8 to 17.2 grams per deciliter (g/dL). Female: 12.1 to 15.1 g/dL.Normal range for children: Newborn: 14 to 24 g/dL. Infant: 9.5 to 13 g/dL. The normal hemoglobin levels for adults according to Mayo Clinic are similar, with the ranges slightly broader by a few points.For children, the ranges vary with age and sex.Hemoglobin transports oxygen from the lungs into the body’s cells and transports carbon dioxide out.nfant: 9.5 to 13 g/dL.

Blood About 98.5% of the oxygen in a sample of arterial blood in a healthy human breathing air at sea-level pressure is chemically combined with the Hgb. About 1.5% is physically dissolved in the other blood liquids and not connected to Hgb.lood accounts for 7% of the human body weight, with an average density of approximately 1060 kg/m 3, very close to pure water's density of 1000 kg/m 3. The average adult has a blood volume of roughly 5 litres (11 US pt), which is composed of plasma and several kinds of cells.

Erythrocytes Though the pulse oximeter actually measures the saturation of oxygen in your blood, the results are often used as an estimate of blood oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low. 1  Causes.

- 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.

OXYGEN SATURATION **During sleep people breathe more shallow and less often. This is normally not a problem, but when there is a lung or heart problem this can cause the oxygen level to be low during sleep. Normally the oxygen level in the blood should be 80 to 100 mm Hg at sea level.The normal oxygen saturation of the blood is 92% to 94% at sea level.When the oxygen level is chronically low the workload on the heart is increased.ithout heart or lung disease, a low oxygen level while sleeping can simply be the result of a sleep disorder. This is especially true if the oxygen is low only while sleeping. Obstructive Sleep Apnea is a sleep disorder in which the airway does not fully open during sleep.

Understanding the Results At sea level, a normal blood oxygen level (saturation) is usually 96 - 97%. Although there are no generally accepted classifications for severity of oxygen desaturation, reductions to not less than 90% usually are considered mild.

- Evaluation of pulse oximetry. In healthy patients, oxygen saturation levels lie between 96 and 98 %. Values below 95 % can indicate a health disorder and make it necessary to supply the patient with additional oxygen. If your oxygen saturation value is below 95 %, please consult your physician. Normal pulse values depend on the age and fitness level of the individual. Here are a few reference values indicating normal pulse rates: Infants under 1 year: 100 – 160 bpm.

- Oxygen saturation over 94% is considered normal.

What is oxygen? Oxygen is a non-metallic element that constitutes for 21% of air. In humans, oxygen is primarily absorbed via the lungs and carried around the body in blood cells to provide the key element for cellular activity.The average level of oxygen in the blood is approximately 96% and if this oxygen consumption lowers over time, your health can be affected.n humans, oxygen is primarily absorbed via the lungs and carried around the body in blood cells to provide the key element for cellular activity.

Definition By Mayo Clinic Staff. Hypoxemia is a below-normal level of oxygen in your blood, specifically in the arteries. Hypoxemia is a sign of a problem related to breathing or circulation, and may result in various symptoms, such as shortness of breath. Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery (arterial blood gas). It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter — a small device that clips to your finger. Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen.

What Are the Effects of Low Blood Oxygen Levels? The most common effects of low blood oxygen levels are related to the respiratory system. In an effort to increase the amount of oxygen in the blood, breathing increases above the normal rate of around 12 to 16 breaths per minute. Rates of 24 breaths per minute or even higher may occur.

What Is a Normal Resting Blood Oxygen Level? Normal Blood Oxygen Levels. Healthy people have a normal range of oxygen saturation from 95% – 100%, although levels down to 90% are common and not usually cause for alarm.During exercise, the increased oxygen consumption may reduce blood saturation, but the increased breathing rate and blood flow compensate for this.ecause hemoglobin saturated with CO (carbon monoxide) can not be differentiated from that with oxygen, a pulse oximetry test may indicate the blood level is normal, when in fact the oxygen levels are low.

A blood cell is said to be saturated when carrying a normal amount of oxygen. Both too high and too low levels can have adverse effects on the body.

Is My Blood Oxygen Level Normal? Normally, a PaO2 reading below 80 mm Hg or a pulse ox below 95 percent is considered low. It’s important to know what is normal for you, especially if you have a chronic lung condition. Your doctor can provide recommendations as to what ranges of oxygen levels are acceptable for you.
