Fiber Optic Pulse Oximetry

Pulse Oximetry allows noninvasive monitoring of arterial blood oxygen saturation. Fiber optic oximetry sensors are used to transmit pulses of red and infrared light through the animal’s peripheral vascular region. Oxygen saturation is determined by measuring the differential absorption of the red and infrared light. In addition to oxygen saturation, the module measures the cardiac plethysmogram waveform, pulse distension, generates a plethysmogram gate and measures the animal’s heart rate.

Description

Pulse Oximetry allows noninvasive monitoring of arterial blood oxygen saturation. Fiber optic oximetry sensors are used to transmit pulses of red and infrared light through the animal’s peripheral vascular region. Oxygen saturation is determined by measuring the differential absorption of the red and infrared light. In addition to oxygen saturation, the module measures the cardiac plethysmogram waveform, pulse distension, generates a plethysmogram gate and measures the animal’s heart rate.  Pulse Oximetry is an available option for the MR-compatible Model 1025 and 1030 Monitoring and Gating Systems and for the Model 1025L and 1025T systems for use in PET, CT, SPECT, Optical and in the laboratory. When used in the MR environment, the Pulse Oximeter Module is located next to the magnet bore.  A fiber optic sensor extends into the bore and attaches to the animal. The module has bi-directional fiber optic communication to the Control/Gating Module. Fiber optic pulse oximetry sensors are constructed so the fibers can be detached from the clip or form that attaches to the animal.  Small, large and extra large clips as well as mouse and rate tail/ankle forms are available. The sensors are typically attached to the foot, but other useful locations include the thigh, ankle, paw, wrist, tail, etc.  For rabbits, the ear is often the location of choice. For animals with black hair, the signal can be improved by shaving. A white rat is shown below prepared for MR with pulse ox, respiration and temperature sensors. The large pulse ox clip sensor is attached to the rat’s foot. Pulse Oximetry    The
