Quick Answer: What Does A Pulse Oximeter Tell You?

What are the 2 readings on a pulse oximeter?

A pulse oximeter is a handy medical device that uses two frequencies of light – red and infrared – to determine the percentage of hemoglobin in the blood that is saturated with oxygen, or your oxygen saturation level.

When oxygen saturation is measured using a pulse oximeter, it is referred to as Sp02..

What is the lowest oxygen level you can live with?

The lower the oxygen level, the more severe the hypoxemia. This can lead to complications in body tissue and organs. Normally, a PaO2 reading below 80 mm Hg or a pulse ox (SpO2) below 95 percent is considered low. It’s important to know what’s normal for you, especially if you have a chronic lung condition.

Is oxygen level 84 bad?

An oxygen level below 88% can be dangerous for any period of time. An oxygen level below 85% warrants a trip to the hospital. Keep in mind that an oxygen level 80% and lower puts your vital organs in danger, so it is important to keep a blood oxygen level chart handy so you know what levels require immediate treatment.

At what oxygen level do you pass out?

Normal oxygen saturation is usually between 96% and 98%. Any level below this is considered dangerous and warrants urgent oxygen supplementation and/or treatment for your lung condition….Measuring Your Levels.Oxygen Saturation LevelsReadingABG LevelO Sat ResultNormal> 80 mm Hg95% to 100%1 more row

Can a pulse oximeter detect heart attack?

Baseline oxygen saturation by pulse oximetry is useful in establishing the diagnosis and severity of heart failure in acute settings such as myocardial infarction and may have prognostic implications. The diagnosis may be suspected when baseline oxygen saturation by pulse oximetry is <93.

What is normal pi %?

– Perfusion Index, or PI, is a relative assessment of the pulse strength at the monitoring site. – PI display ranges from . 02% (very weak pulse strength) to 20% (very strong pulse strength).

What is a good reading on a pulse oximeter?

Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low.

What do the numbers mean on a pulse oximeter?

A normal ABG blood oxygen level for healthy lungs will usually fall between 80 and 100 millimeters. If using a pulse oximeter, this reading should typically be between 95 and 100 percent.

What should your heart rate be on a pulse oximeter?

Breathing normal room air at your normal respiration rate, you should have an oxygen saturation somewhere between 95 and 100 percent and a pulse rate between 60 and 100. This means your heart is beating normally all the while carrying enough oxygen to the rest of your body to keep you healthy.

What are the symptoms of not enough oxygen in the blood?

Symptoms of Low Oxygen in Blood (Hypoxemia)Confusion.A sense of euphoria.Restlessness.Headache.Shortness of breath.Rapid breathing.Dizziness, lightheadedness and/or fainting spells.Lack of coordination.More items…•
