Blood oxygen level refers to the amount of oxygen that is circulating inside the blood. Red blood cells carry oxygen from the lungs to various body organs. The amount of oxygen in a person’s blood is an important measure of how efficiently their body carries oxygen from their lungs to their cells and it is important to learn about it so you can understand how low can your oxygen level go before you die.

Each cell obtains enough oxygen because the body closely regulates blood oxygen levels to keep them within a predetermined range. Healthy individuals have blood oxygen levels between 75 and 100 millimeters of mercury (mm Hg). When arterial blood gas (ABG) test results show an oxygen level below 60 mm Hg, the medical community considers it low. People who experience these consequences can occasionally need additional oxygen.

The range of a normal oxygen saturation is between 95% and 100%. If a person’s levels go below this range, they may experience oxygen deficiency symptoms such difficulty breathing and confusion. Keep reading to know how low can your oxygen level go before you die and the risk related to lower oxygen level.

How low can your oxygen level go before you die?

At least 95% of the air is normally oxygenated. 90% of patients with sleep disorder and persistent lung disease could have normal levels.

The range of normal oxygen saturation rates is typically believed to be between 95% and 100%. When the value falls below 90%, the patient’s condition begins to seriously deteriorate, and when it approaches 70%, it becomes life-threatening.

The patient’s condition may also worsen further. Before the oxygen saturation falls to 90%, the pao2 may drop from 100 mm hg to 60 or 70 mm hg. You can observe symptoms of distortions such as low blood pressure, accelerated breathing and heart rate.

In addition to feeling out of breath, when your oxygen level falls to 70, you will also have headaches and vertigo. If you have any of these symptoms, you should speak with your doctor right away so that you can be given extra oxygen to increase your blood’s oxygen saturation. This is approximately how low can your oxygen level go before you die.

How do you measure blood oxygen level?

To measure the amount of oxygen in your blood, doctors frequently use one of two tests. To maintain track of your health and know how low can your oxygen level go before you die you should check your blood oxygen level daily.

Pulse oximeter test

The most popular method for monitoring blood oxygen levels is a pulse oximeter test. This examination is non-invasive because no needle or other item is put into your body. For this test, your doctor will make use of a device called a pulse oximeter. The device, which is connected to a pulse oximeter, measures the amount of oxygen in your blood in your capillaries. Capillaries, which are systems of microscopic blood vessels, connect your arteries and veins.

The pulse oximeter is simple to use, painless, and rapid to return test results. A pulse oximeter is a wonderful device if you need to often measure and monitor your blood oxygen level.

Arterial blood gas (ABG) test

The most accurate technique to evaluate your blood oxygen level is through an ABG. Your doctor will use a needle to draw blood from one of your arteries in order to do this test. Montering your oxygen level is important and only then you find out how low can your oxygen level go before you die so you can contact your doctor immediately.

The method used to take blood for an ABG test is distinct from that utilized for the majority of blood tests. Doctors will take blood from one of your veins that is near to the skin and simple to access because a routine blood test does not require oxygenated blood. Blood is typically drawn from arm veins during routine blood tests.
