For healthy lungs, a normal ABG oxygen level is between 80 and 100 millimetres of mercury (mm Hg). If your blood oxygen level (SpO2) was measured using a pulse oximeter, a normal reading would be between 95 and 100 percent.
FAQ About Fingertip Pulse Oximeter
The standard range for pulse oximeter readings is 95 to 100 percent. Low values below 90% are considered low and signal the need for additional oxygen.
Around saturations of 90-100 percent, pulse oximeter accuracy is highest, intermediate at 80-90 percent, and lowest below 80 percent. Because of the limitations of individual precision, SpO2 is more useful for trends over time rather than absolute thresholds.
The right middle finger and right thumb have a greater statistical value, making them ideal for use with a pulse oximeter.
Heart rates that are consistently above 100, even when the patient is sitting quietly, can sometimes be caused by an abnormal heart rhythm. A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body.
OuAt repose, children's heart rates range from 70 to 100 beats per minute (ages 6 to 15). Adults (age 18 and up) have a heart rate of 60 to 100 beats per minute.
Resting heart rates for most healthy adult women and men range from 60 to 100 beats per minute.
A resting heart rate of 60 to 100 beats per minute is considered typical for most people. Your heart is slower than normal if it beats less than 60 times per minute. A sluggish heart rate might be healthy and typical. It could also be an indication of a problem with the electrical system of the heart.
