Pulse Oximeters

Once only available as a part of larger patient monitoring systems, the standalone pulse oximeter has become standard in physicians’ offices and clinics around the world. From portable to wall-mounted, each meter is designed with easy-to-read interfaces to allow for maximum usability. Featuring ADC, Advantage Medical Cables, Bionet, Datex-Ohmeda, Edan Instruments, Foremost, GE Medical, Masimo, Nellcor, Nonin Physio-Control AEDs, SDI Diagnostics, Smiths Medical, and Venni products, every pulse oximeter is inspected, calibrated, and ready to use as soon as you receive it. New and refurbished models are available making these devices more affordable than ever.

How does a pulse oximeter work?

Pulse oximeters measure the oxygen saturation in the bloodstream by using a non-invasive light source and a light detector. A light source is on one side of the pulse oximeter sensor while the detector is on the other. A finger is placed between the source and detector forcing light to pass through the finger. The amount of light that is absorbed depends on the amount of oxygen-carrying blood cells in the finger. A low concentration of these cells yields a low absorption rate of the light in the finger. A high concentration of oxygen yields a high absorption rate of light in the finger. This data is then translated into a number on a digital screen. If a patient has an SPO2 of 100 on room air, their blood cells are receiving adequate amounts of oxygen. If the number is lower than the clinical standard, they require additional medical assistance. 

Additional Features

Some pulse oximeters are wall-mounted models featuring on-board printers and cabled sensors. Others are handheld or even wrist-worn devices that can detect a patient’s SPO2 without additional cables or sensors. Additional batteries, sensors, cables, adapters, carrying cases, paper, and testers are available to maintain your pulse oximeter for years to come.
