A discussion on CPAPtalk talks about the importance of tracking oxygen levels. One of the recording machines mentioned was the Nonin Wrist pulse Oximeter 3100 which uses a finger probe. At one time it was being offered for $300 on eBay. With additional software it's data can be downloaded to a PC.

- The Fingertip Pulse Oximeter and Heart Rate Monitor is a non-invasive method allowing the monitoring of the oxygenation of a patient's hemoglobin. A sensor is placed on a thin part of the patient's anatomy, usually a fingertip or earlobe, or in the case of a neonate, across a foot, and a light containing both red and infrared wavelengths is passed from one side to the other. Changing absorbance of each of the two wavelengths is measured, allowing determination of the absorbances due to the pulsing arteria blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) fingernail polish.
- A pulse oximeter is a device used to measure oxygen as a percentage of blood gases in a non-invasive manner. It uses a sensor that is placed over a thin part of a patient's body, usually their fingertip, but in the alternative an earlobe. Two different wavelengths of light are emitted on one side to be picked up by a sensor on the other side. These wavelengths are chosen because they will not be affected by other substances, including fat, bone, veins or even nail polish. They will only be affected by blood in the arteries. The sensor results are analyzed with a computer that displays the result on a monitor.

| - The Fingertip Pulse Oximeter and Heart Rate Monitor is a non-invasive method allowing the monitoring of the oxygenation of a patient's hemoglobin. A sensor is placed on a thin part of the patient's anatomy, usually a fingertip or earlobe, or in the case of a neonate, across a foot, and a light containing both red and infrared wavelengths is passed from one side to the other. Changing absorbance of each of the two wavelengths is measured, allowing determination of the absorbances due to the pulsing arteria blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) fingernail polish. Based upon the ratio of changing absorbance of the red and infrared light emitted causes a difference in color between oxygen-bound (bright red) and oxygen unbound (dark red or blue, in severe cases) blood hemoglobin, a measurement of oxygenation (the per cent of hemoglobin molecules bound with oxygen molecules) can then be made. How does it work? To use this health gadget you just insert your finger then press the power button and the Finger Pulse Oximeter and Heart Rate Monitor will display your heart beat p/m, the percentage of oxygen in your blood and also displays an indicator bar that increases and decreases by syncing with the rhythm of your heart beat. The bar graph serves the purpose of letting you know if you’ve got a weak or strong hear based on the level of the graph. You get all this without needing to go to the hospital, see a doctor or have any invasive procedure.

Although a pulse oximeter is not a complete solution to determine whether a patient is getting proper respiration or bloodflow, it does have the advantage of being able to provide a quick and continuously updated result.
