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, otherwise known as your oxygen saturation level (O2 sat level).

Does your oxygen level drop when you sleep?

Everyone’s oxygen levels in the blood are lower during sleep, due to a mildly reduced level of breathing. Also, some alveoli drop out of use during sleep. If your waking oxygen saturation is greater than about 94 percent on room air, it is unlikely that your saturation during sleep will fall below 88 percent.

Does your oxygen level drop when you have a heart attack?

A heart attack, or myocardial infarction, is a medical emergency in which the supply of blood to the heart is suddenly and severely reduced or cut off, causing the muscle to die from lack of oxygen.

What happens to your oxygen level during a heart attack?

Recent mechanistic studies have highlighted the potential adverse effects of supplemental oxygen to the heart. Simply, our bodies respond to excess of oxygen by decreasing the blood flow to the various organs. During a heart attack, this response may further reduce blood flow through the coronary arteries.
