Measuring Oxygen Level in the Blood - Virus 19

Pulse Oximeter (Credit to Insider)

We always hear and familiar with the word “ventilator,” a life saving device during current pandemic Covid 19.

Why Covid 19 patients need ventilator?

You might know that it is because low concentration of oxygen level in the blood, and the fact that virus drown the lung, thus lung can’t inhale and exhale air in normal ways.

How we can say our oxygen level is normal?

There are two common available methods:

1) Measurement of PaO2 (partial pressure of oxygen dissolved).

- the normal reading is 80 mm Hg

2) Measurement of Oxygen saturation or pulse Oxygen (SpO2).

- the normal level of oxygen is 95% to 100%

The lawn mower, just for illustration

You may have medical device called Pulse Oximeter to measure Oxygen saturation or pulse Oxygen at your home.

Oximeters are available in many stores or Pharmacy such as Walgreen, CVS, Target, Walmart or Amazon.

Prices of Pulse Oximeter are ranging from US$ 4.77 to US$ 299. Quite reasonable for me if price is about US$ 19.99.

Moreover, in case your Pulse Oxygen level below 90%, it is mean the oxygen level is not normal.

In addition to lower pulse oxygen level, people should go to hospital and need treatments when they face with conditions of:

- serious illness

- difficult to breathing

Do you think that should you have this kind of medical device available at your home?
