Estimating the term…
A blood oxygenation monitoring device may comprise an extracorporeal pulse simulation system including one at least partially transparent blood holding element with a photoplethysmographic sensor coupled to the element and adapted to measure particular gas content of the blood. The system includes a pulse simulation mechanism configured to simulate pulsatile behavior of the blood within the element relative to the photoplethysmographic sensors. The blood holding element may be a reservoir, wherein the pulse simulation mechanism includes a magnetic stirrer and stir bar within the reservoir. The blood holding member may be flexible tubing having blood flow there through, wherein the pulse simulation mechanism is a peristaltic pump coupled to the tubing. The monitoring device can rapidly and accurately form oxygen dissociation curves. The monitoring device can be utilized in conjunction with a heart lung bypass machine or other extra corporeal circuit devices or can be a calibration tool for sensors.
