How much oxygen consumption is necessary for an adult per day?
Written by Author

The average adult at rest inhales and exhales something like 7 or 8 liters of air per minute (maybe some variation). That totals something like 11,000 liters of air (388 cubic feet) per day.

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.

What Are The Differences Between Industrial Oxygen And Medical Oxygen?

Medical oxygen is high purity oxygen that is used for medical treatments or especially for hospital and clinical use and is developed for use in the human body. Medical oxygen cylinders contain a high purity of oxygen gas; no other types of gases are allowed in the cylinder to prevent contamination or other problems.

There are additional requirements and rules for medical oxygen, including requiring a person to have a prescription to order medical oxygen by a doctor any medical personnel.

Industrial oxygen is focused on uses in industrial plants including, oxidation, cutting, combustion, and chemical reactions. The industrial oxygen purity levels are not appropriate for human use and there could be impurities from dirty equipment or industrial storage that could make people ill.

What are normal readings of oxygen in the human body?

A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels of around 90%.(it is also dependent on the patient’s condition ) The “SpO2” reading on a pulse oximeter shows the percentage of oxygen present in the blood.

If your home SpO2 reading is lower than 95% or less then that so, call your health care provider or meet your family doctor.

What is a pulse oximeter?

pulse oximeter

Apulse oximeter is a medical device that help to messure the level of oxygen presence in the blood.

A pulse oximeter measures how much oxygen is in someone’s blood.

It is a small device that clips onto a finger or another part of the body. They are used often in hospitals and clinics and can be bought to use at home(especially used in covid-19 or any lung problem).

Many people consider oxygen level an important sign of how well a body is working, just like a person’s blood pressure or body temperature.

People who have a lung or heart condition may use a pulse oximeter at home to check how they are doing, as directed by their health care provider.

People can buy pulse oximeters without a prescription at some pharmacies and stores for home use.

what is the use of a pulse oximeter during COVID-19? how well they are doing if they have it?

Pulse oximetry results may not be as accurate for people with darker skin. Their oxygen levels are sometimes reported as higher than they really are. People who check their own oxygen levels, or those who check it for them, should keep this in mind when looking at results(The result may be different from people to people).

We do not recommend using a pulse oximeter as a way to tell if someone has COVID-19. Get tested if you have signs of COVID-19 or if you have been close to someone who has it or who has to diagnose with medical reports, blood investigation, CT Scan.

If someone has COVID-19, a pulse oximeter may help them keep watch over their health especially oxygen level in blood or difficulty in breathing, and to know if they need medical care.

However, while a pulse oximeter may help someone feel like they have some control over their health, it does not tell the whole story.

Not fully depend on the pulse oximeter during COVID- 19 or any other chronic disease condition.

Oxygen levels may be low if someone feels short of breath, is breathing faster than usual, or feels too sick to do their usual daily activities, even if a pulse oximeter says their oxygen levels are normal. Call a doctor or another health care provider right away if you have any symptoms related to oxygen inhalation.

How does COVID-19 lower a person’s oxygen levels?

The main causes are not found out today but according to some doctor’s experience, the covid-19 infection makes the lungs hard and stone-like structure so that make difficult to breathing, Many people with COVID-19 have low levels of oxygen in their blood, even when they feel well. Low oxygen levels can be an early warning sign that medical care is needed for any human being so this is primary investing.
