Human Oximetry System
Part #: OXYSSH-SYS

The OXYSSH-SYS is a noninvasive Human Pulse Oximetry System that works in conjunction with an MP36, MP36R, MP35 or MP45* to record saturation of peripheral oxygen in functional hemoglobin (SpO2), reported in units of % O2. Two LEDs on the OXYSS module indicate SpO2 signal status. In addition to SpO2, the OXYSS module supports three auxiliary outputs:

Pulse: A pulse plethysmogram signal that reflects changes in blood density on the finger tip caused by varying blood pressure

Rate: Heart Rate in Beats Per Minute (BPM)

Status optional: Outputs voltage levels that reflect the SpO2 signal status; requires BSLCBL14A interface cable, purchased separately

The system includes the OXYSS Pulse Oximeter module (SpO2 output), a Finger Clip Transducer (TSD124D), a Pulse interface cable (BSLCBL15) and a Rate interface cable (BSLCBL16). The OXYSS is powered by the MP device so no external power supply is required. The system also accepts optional Ear Clip Transducer (TSD124B) and Flex Wrap Transducer (TSD124C).

Compatibility


The SpO2 finger clip transducer is an absorption design that places two light-emitting diodes (LEDs) on the bottom side of the finger and a photodetector on the top side. The LEDs output two different wavelengths; one red (660 nm peak), and one infrared LED (910 nm peak). The photodiode on the top side faces the LEDs and detects the light that is passed through the translucent part of the finger. The LEDs are alternately flashed many times per second allowing the photodiode to respond to the red and infrared light separately. Well-oxygenated blood is bright red, while poorly oxygenated blood is darker in color. The pulse oximeter determines functional oxygen saturation of arterial hemoglobin from this color difference by calculating the ratio of absorbed red and infrared light as the blood volume at the sensor site fluctuates with each heart beat. Since steady conditions (steady venous blood flow, skin thickness, bone, fingernails, etc.) are not pulsatile, they do not affect the saturation reading.

The Oximeter module input accepts currently offered Human Spo2 Transducers; Finger Clip (TSD124D) is included, Ear Clip (TSD124B) and Flex Wrap (TSD124C) will also work. SpO2 output connects to analog CH input via a 1.8 M (6′) cable.

The OXYSSH-SYS utilizes Nonin Medical Inc. pulse oximeter technology which provides accurate and reliable data.

* Note: If using an MP45 two-channel device, only one auxiliary output can be simultaneously recorded in conjunction with the SpO2 output.
