Monitoring your body
Learn from your body by monitoring yourself in the morning, after exercise, or anytime you want to know what your body is telling you
Morning monitoring- Keep your MightySat at your bedside and each morning
- Monitor yourself before you get out of bed
- Establish your normal, or “baseline” values
- Oxygen saturation (SpO2)
- A fully oxygenated body generally means a fully recovered and ready body. An SpO2 between 97 and 100% means your body is ready!
- Note: At higher elevation starting at about 3,000 feet, it is normal for your SpO2 to be 3 to 5% lower. The higher elevation you go, the lower your SpO2 will be.
- Pulse Rate (PR)
- Your pulse rate changes constantly to provide the necessary blood flow to deliver the oxygen your body needs. Generally, a lower resting pulse rate (40 to 60 beats per minute) means your body is performing more effectively and efficiently.
- Perfusion Index (Pi)
- Your perfusion index changes based on whether the blood flow to your body is going up or down, and whether the arteries in your fingers are narrowing (causing your fingers to feel colder) or widening (causing your fingers to feel warmer). There is no specific “normal” value for perfusion index, each person should establish their own baseline value and note how it changes over time. A higher perfusion index means greater blood flow to the finger and a lower perfusion index means lower blood flow to the finger. Your perfusion index may or may not change significantly in the morning or after exercise. Note any changes to your perfusion index and whether you feel any differently when your perfusion index is lower.
After exercise monitoring
- Keep your MightySat with you when you exercise
- Immediately after exercise, measure how long it takes for your measurements to change
- Oxygen saturation (SpO2)
- Measure how long it takes for your oxygen saturation to return to your baseline value (example, from 95% to 98%).
- Pulse Rate (PR)
- Measure how long it takes for your pulse rate to go down by 20 beats per minute (example, from 160 to 140 beats per minute).
Live at your best by tracking and trending your data to make adjustments in exercise, diet, or rest/relaxation
Morning monitoring- Oxygen saturation (SpO2)
- If your oxygen saturation drops more than 3% from baseline, or if it is below 96%, this may be an indication that you need more rest and recovery
- Pulse Rate (PR)
- If your resting pulse rate is 10 beats per minute higher than normal, this may be an indication that you are dehydrated, stressed, or fatigued. This may be an indication that you need to rehydrate, relax, or skip intense workouts.
After exercise monitoring
- Oxygen saturation (SpO2)
- If your oxygen saturation takes longer to return to your baseline value, this may be an indication that you need more rest and recovery.
- Pulse Rate (PR)
- If your pulse rate takes longer than usual to fall by 20 beats per minute, this may be an indication that you need:
- To rehydrate
- Give yourself more rest and recovery
- Change your workout regimen, as you may have hit a plateau and may need a different type of workout to make progress (example, if you have been doing all aerobic training at moderate pulse rate levels, you may need to consider more interval training at higher pulse rate levels to improve your recovery time).
- If your pulse rate takes longer than usual to fall by 20 beats per minute, this may be an indication that you need:

What is Perfusion Index?
Perfusion Index, often abbreviated PI, is a measurement obtained from a pulse oximeter that is calculated as the ratio of pulsatile blood flow to the non-pulsatile blood in peripheral tissues (Hales et al. 1989). Simply put, it is the ratio of pulsing blood to non-pulsing blood. This measurement can be acquired non-invasively and is a good indicator of a user’s pulse strength. Measurements generally range from 0.02% (very weak pulse) to 20% (very strong pulse). The plethysmograph generated by the pulse oximeter is a graphical illustration of the user’s PI. Physician’s often use this measurement to gain a better understanding of the effects of a drug or treatment on a patient. It can also be used to gain insight into medicinal efficacy and track disease progression.
What is a “Normal” PI value?
PI is affected by a variety of factors that are directly attributed to the user’s physiological condition, and the site at which the measurement is being taken (fingertip, earlobe, forehead, etc.) Because there is such a high degree of variability in these parameters, individual users should establish their own normal PI percentage with a doctor.
It is good to keep in mind that pulse oximeters also measure blood oxygen saturation (SpO2 levels) and pulse rate (PR). These values together can provide basic, yet necessary information regarding the user’s current well-being and health condition.
Interested in monitoring your PI? CMI Health offers a variety of Pulse Oximeters and sensors designed to suit each user’s individual needs. This includes Handheld Pulse Oximeters, recommended for spot checking or continuous, overnight use. There are a variety of sensors available to pair with this device, each designated to meet different user requirements. We also offer portable, digital spot-checking fingertip pulse oximeters. These devices are great for on-the-go monitoring. If your looking for an easy to wear overnight pulse oximeter, we suggest checking out the OxyKnight Watch wrist oximeter, designed for comfortable, continuous use.
