FREQUENTLY ASKED QUESTIONS ABOUT PULSE OXIMETER
The middle six right finger has a statistically high value, making them ideal for a pulse oximeter .
It is accurate when the oxygen filling is less than 80%. Consider the accuracy limits when using a pulse oximeter to assist in finding and making decisions. Use pulse oximeter readings as a measure of oxygen filling.
90% or less This oxygen level is very pronounced and may indicate a serious medical problem. Call 911 or go to the nearest emergency room immediately. You may need an urgent x-ray or a heart test. 91% to 94% This oxygen level is related and may indicate a medical problem.
The normal oxygen level is usually 95% or more. Some people with chronic lung disease or sleep apnea may have normal levels around 90%. A reading of “SpO2” on the pulse oximeter indicates the percentage of oxygen in a person’s blood. If your SpO2 reading is less than 95%, call your healthcare provider.
We have listed 5 important ways of supplementing oxygen:
Get fresh air. Open your windows and go outside.
Drink water. In order to release oxygen and expel carbon dioxide, our lungs need to be inflated and absorbed enough water, which, in turn, influences oxygen levels.
Eat foods rich in iron.
Train your breathing.
They rely on the sensor to detect light in body tissues and to measure the amount of light absorbing oxygen-containing hemoglobin. If ambient light enters the test area, this may result in the pulse oximeter not producing any readings at all, or producing incorrect readings.
It shows two important readings: pulse rate, recorded as a bit per minute and oxygen saturation of hemoglobin in the bloodstream.
Normal heart rate at rest: Children (ages 6 – 15) beat 70 – 100 beats per minute. Adults (18 years and older) 60 – 100 beats per minute.
