What are the 3 readings on a pulse oximeter?

The pulse oximeter measures the pulse rate, blood oxygen saturation (SpO2), the perfusion index (PI), and in some of the machines, (not all) the respiratory rate (RR). The pulse rate can normally show a wide variation of 60-110 beats per minute (bpm).

What is normal SpO2 and PR bpm pi?

An ideal oxygen level is between 96% and 99% and an ideal heart rate is between 50 and 90 beats per minute (bpm). The oxygen level may be lower in some people with lung conditions, even when they are feeling well. If you have an existing lung condition, please check with your doctor about what your readings should be.

Is 120 a normal pulse rate?

According to the American Heart Association, a normal adult resting heart rate is between 60 beats per minute (BPM) and 100 BPM for people 15 years and older. A resting pulse rate of 120 BPM in adults would be considered high.

Why and when use a pulse oximeter?

When the capacity of the lungs to transport oxygen into the blood is impaired, blood oxygen saturation declines, potentially putting our organs in danger. A pulse oximeter can quickly detect this drop in oxygen saturation, alerting people of the need for medical intervention.

What does a pulse oximeter tell you?

– Heart attack – Heart failure – Chronic obstructive pulmonary disease (COPD) – Anemia – Lung cancer – Asthma – Pneumonia

What does a pulse oximeter tell us?

Reduced peripheral pulsatile blood flow.

Venous congestion of an arm or leg may affect readings,as can a badly positioned sensor.

Bright overhead lights,such as in an operating theatre,may interfere with the sensors ability to read the red or infrared light correctly and cause the oximeter to be inaccurate.

How to use a pulse oximeter correctly?

You are wearing nail paint

You have henna pigment

There is a bright light on the probe

Too much body movement

There is poor perfusion

Carbon monoxide poisoning
