Things to Know When Using Oxygen Therapy

What are the disadvantages of oxygen?

High concentrations of oxygen, over a long period of time, can increase free radical formation, leading to damaged membranes, proteins, and cell structures in the lungs. It can cause a spectrum of lung injuries ranging from mild tracheobronchitis to diffuse alveolar damage.

What should you not do while on oxygen?

Never smoke, and don't let others light up near you. Keep away from open flames, such as matches, cigarette lighters, and burning tobacco. Stay 5 feet away from heat sources. That includes gas stoves, candles, lighted fireplaces, and electric or gas heaters.

At what oxygen level is a ventilator needed?

Normal oxygen saturation levels range between 94%-99%. When SPo2 levels fall below 93% it is a sign that oxygen therapy is required.

What is the minimum oxygen level for COVID-19 patients?

Some COVID-19 patients may show no symptoms at all. You should start oxygen therapy on any COVID-19 patient with an oxygen saturation below 90 percent, even if they show no physical signs of a low oxygen level. If the patient has any warning signs of low oxygen levels, start oxygen therapy immediately.

What does it mean to be on 5 liters of oxygen?

Standard oxygen sources can deliver from ½ liter per minute of O2 to 5 liters/minute (L/min). Every liter/minute of oxygen increases the percentage of O2 the patient breathes by 3 – 4 %. Room air is 21% O2. So if a patient is on 4 L/min O2 flow, then he or she is breathing air that is about 33 – 37% O2.

What do you do when your oxygen level is below 90?

Low oxygen level, also called hypoxemia, is considered a reading between 90% and 92%. A reading this low means you might need supplemental oxygen or that there may be challenges that affect how your lungs function. A result below 90% indicates that you should seek medical attention.
