DOI: 10.31038/EDMJ.2019311 Abstract. Rhizomes of Zingiber officinale (ginger) are used as a spice in many culinary dishes of Bangladesh. Since a number of scientific reports are present on the beneficial effects of raw ginger in Type 2 diabetes mellitus, it was of interest to determine the anti-hyperglycemic efficacy of cooked (boiled) ginger through oral glucose tolerance test (OGTT) in mice. Normal arterial blood oxygen saturation levelsin humans are 95–100 percent. If the level is below 90 percent, it is considered low and called hypoxemia. Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Normal SpO2 values vary between 90 and 100%. Good blood oxygenation is necessary to supply the energy your muscles need in order to function, which increases during a sports activity. If your SpO2 value is below 90%, that could be a sign of poor blood oxygenation, also called hypoxia. Oxygen saturation (SaO2) is a measurement of the percentage of how much hemoglobin is saturated with oxygen. Oxygen is transported in the blood in two ways: oxygen dissolved in blood plasma (pO2) and oxygen bound to hemoglobin (SaO2). Anyways, I'm not sure why, all things considered, my sp02 is consistently only 95%. I work on an ambulance and have used a couple different monitors that we have available and use on our patients. Mainly always 95% and sometimes 96%.

Wondering what your blood oxygen saturation level is—and how you can measure it? Let's go through a series of basic Q&As about this vital sign.

Originally published in 2014, this article on blood oxygen has been expanded and now includes pictures of ScanWatch, an innovation featuring SP02 measurement that was announced at CES 2020.

Pulse oximetry is a noninvasive method that enables the measurement of a person’s blood oxygen saturation, which is often referred to as SpO2 or even “The Fifth Vital Sign” (the first 4 being your pulse, temperature, blood pressure and respiratory rate).

It is a percentage that reflects the level of oxygen available in your blood.

Pulse oximetry is a method doctors use for rapid assessment and monitoring of a patient’s respiratory function. It is also used to determine which patients might be suffering from hypoxia (a condition meaning the blood oxygen level is too low) and should take additional tests.

A low level of oxygen in the blood is generally a sign of respiratory failure. The heart and brain are organs that require a lot of oxygen to function, and they are the first to suffer from this pathology, which can sometimes have serious consequences.

Until recently doctors were the only ones to use pulse oximeters, generally in a clinical setting. But as these tools are now more common, self-tracking your SpO2 has become a reality.

In fact, everybody can benefit from tracking their SpO2 themselves. Being healthy doesn’t mean that you won’t benefit from a preventive tracking of respiratory problems—checking your blood oxygenation can provide you with an early warning sign (plus you’ll have a history of measurements to show your doctor, which they are likely to welcome).

If you are a mountaineering fan or an athlete training at high altitudes to boost your endurance, measuring your oxygen saturation rate is very important as it can highlight potentially life-threatening hypoxic conditions.

This easy-to-use method is also great for people with a variety of chronic conditions, including asthma and COPD (chronic obstructive pulmonary disease), as it allows them to quickly assess the severity of their condition.

Oximetry also allows patients undergoing oxygen therapy to adjust the flow rate of their oxygen cylinders and offer regular and accurate measurements to their doctors.

ScanWatch is a real watch and also an activity and sleep tracker with ECG functionality. But it also offers blood oxygen as a metric. The ScanWatch SpO2 sensor is located under the body of the watch. It uses the principle of reflection. It emits and then absorbs a red light wave which it sends through the blood vessels in order to analyze the oxygen saturation in the user’s blood. ScanWatch has an optical sensor that uses photoplethysmography (PPG) technology. It is based on an elementary principle: blood is red because it reflects red light. ScanWatch therefore uses red and infrared LEDs as well as light-sensitive photodiodes to detect the oxygen saturation in the blood of the veins crossing the wrist. A red LED and an infrared LED light up and radiate through your wrist. The ratio of red to infrared light passing through the ScanWatch photodiode indicates the percentage of oxygenated hemoglobin compared to the deoxygenated hemoglobin in your blood. This oxygen saturation in the blood is also called SpO2.

Oxygen saturation (SpO2) is an estimate of the amount of oxygen in your blood. It is given as a percentage of the maximum oxygen it can carry. Your SpO2 is considered normal if it is greater than 95%. If it is 95% or less, your blood has an abnormally low oxygen level and we recommend that you speak to your doctor. If the SpO2 is below 90%, the individual is at risk of developing hypoxemia. Symptoms may include shortness of breath, especially during brief exercise or even at rest.

Hopefully this list of SpO2-related frequently asked questions has quenched your thirst for knowledge about your blood oxygen level. But if you have concerns about your own SpO2, it is always a good idea to consult with a health professional.

Spo2 95%

Oxygen saturation is 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 arterial blood oxygen saturation levels in humans are 95–100 percent. If the level is below 90 percent, it is considered low and called hypoxemia.^[1] Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to respiratory or cardiac arrest. Oxygen therapy may be used to assist in raising blood oxygen levels. Oxygenation occurs when oxygen molecules (O
₂) enter the tissues of the body. For example, blood is oxygenated in the lungs, where oxygen molecules travel from the air and into the blood. Oxygenation is commonly used to refer to medical oxygen saturation.

Definition[edit]

In medicine, oxygen saturation, commonly referred to as 'sats', measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.^[2] At low partial pressures of oxygen, most hemoglobin is deoxygenated. At around 90% (the value varies according to the clinical context) oxygen saturation increases according to an oxygen-hemoglobin dissociation curve and approaches 100% at partial oxygen pressures of >11 kPa. A pulse oximeter relies on the light absorption characteristics of saturated hemoglobin to give an indication of oxygen saturation.

Physiology[edit]

The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing. Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body. The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required ^[3] or when living at higher altitudes. A blood cell is said to be 'saturated' when carrying a normal amount of oxygen.^[4] Both too high and too low levels can have adverse effects on the body.^[5]

Measurement[edit]

An SaO₂ (arterial oxygen saturation, as determined by an arterial blood gas test^[6]) value below 90% indicates hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO₂ is indicated by cyanosis. Oxygen saturation can be measured in different tissues:^[6]

• Venous oxygen saturation (SvO₂) is the percentage of oxygenated hemoglobin returning to the right side of the heart. It can be measured to see if oxygen delivery meets the tissues' demands. SvO₂ typically varies between 60% and 80%.^[7] A lower value indicates that the body is in lack of oxygen, and ischemic diseases occur. This measurement is often used under treatment with a heart lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy.
• Tissue oxygen saturation (StO₂) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea of tissue oxygenation in various conditions.
• Peripheral oxygen saturation (SpO₂) is an estimation of the oxygen saturation level usually measured with a pulse oximeter device. It can be calculated with pulse oximetry according to the formula^[6] where HbO₂ is oxygenated hemoglobin (oxyhemoglobin) and Hb is deoxygenated hemoglobin.

Pulse oximetry[edit]

Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood.^[8] This approximation to SaO₂ is designated SpO₂ (peripheral oxygen saturation). The pulse oximeter consists of a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and transfers its readings to a reading meter by wire or wirelessly. The device uses light-emitting diodes of different colours in conjunction with a light-sensitive sensor to measure the absorption of red and infrared light in the extremity. The difference in absorption between oxygenated and deoxygenated hemoglobin makes the calculation possible.^[6]

What Should Your Oxygen Level Be

Medical significance[edit]

Healthy individuals at sea level usually exhibit oxygen saturation values between 96% and 99%, and should be above 94%. At 1,600 meters' altitude (about one mile high) oxygen saturation should be above 92%.^[9]

An SaO₂ (arterial oxygen saturation) value below 90% causes hypoxia (which can also be caused by anemia). Hypoxia due to low SaO₂ is indicated by cyanosis, but oxygen saturation does not directly reflect tissue oxygenation. The affinity of hemoglobin to oxygen may impair or enhance oxygen release at the tissue level. Oxygen is more readily released to the tissues (i.e., hemoglobin has a lower affinity for oxygen) when pH is decreased, body temperature is increased, arterial partial pressure of carbon dioxide (PaCO₂) is increased, and 2,3-DPG levels (a byproduct of glucose metabolism also found in stored blood products) are increased. When the hemoglobin has greater affinity for oxygen, less is available to the tissues. Conditions such as increased pH, decreased temperature, decreased PaCO₂, and decreased 2,3-DPG will increase oxygen binding to the hemoglobin and limit its release to the tissue.^[10]
