Pulse Oximeter : Use for Management of COPD and CHF Patient

The most common pulse oximeter for home users is fingertip pulse oximeter. These devices are non-invasive and only about the size of a pack of gum. They are placed over your first finger so the LEDs emit through the fingernail.

This is convenient and effective. Your heart rate and oxygen level are measured and displayed on an LED display. Typically the pulse oximeter is battery powered and operates with only the touch of one button. More advanced models are available with color displays but more importantly, memory.

A pulse oximeter with memory allows the user to consistently track their levels over longer time periods and even while sleeping. These recorded sessions can be conveyed to the treating doctor in case of updates to the treatment are required.

Patients with CHF may have reasonable oxygen levels much of the time but using the data recording feature of a wrist pulse oximeter allows users to track their level over time to check for sporadic reduction of oxygen levels and heart rate. This can happen during the patient's sleep.

More advanced pulse oximeters have audible alarms that can be set for specified minimum oxygen levels and heart rate. A wrist pulse oximeter still uses a sensor on the fingertip but the display unit and memory are worn on the wrist exactly like a wristwatch. These models are typically best for use at night while sleeping.
