GUIDO RAYOS X, S.A.30IV.3. SHELVESShelf for monitors.Shelf for instruments.Those shelves can be installed in both sides of the unit and its height can be regulated,using the accessories rail placed on the rear of the column.IV.4. OTHER OPTIONAL ACCESSORIESTray for X-ray cassettes.Oxygen tent hod with security valve.Holding assembly for two gas cylinders.Drawers assembly.IV.5 PULSEOXIMETRY MODULE.The NESTOMAT 6050 (6100 Version) is a Neonatal Care Center that noninvasivelyand continuously monitors arterial blood oxygen saturation (SaO2) and pulse rate.SaO 2 and pulse rate information is conveyed both visually and audibly. A custom highcontrast Liquid Crystal Display (LCD) with backlighting indicates the SaO 2 , pulse rate,pulse signal strength and system messages. The tone generator "beeps" with each pulsebeat. The pulse "beep" momentarely changes to a lower tone "beep" when there is adecrease in SaO 2 .It has a flexible alarm system with audible and visual indi cators. The high and lowalarm limits are user adjustable. The audible alarm and pulse "beep" volume can beadjusted or inhibited by the user.Theory of OperationThe NESTOMAT 6050 (6100 Version) determines SaO 2 and pulse rateby passing two wavelengths of light, one red and one infrared, throughbody tissue to a photodetector. Pulse identification is accomplished byusing plethysmographic techniques, and oxygen saturation measurementsare determined using spectrophotometric oximetry principles. Duringmeasurement, the signal strength resulting from each light source dependson the color and thickness of the body tissue, the sensor placement,the intensi-ty of light sources and the absorption of the arterial andvenous blood (including the time varying effects of the pulse) in the bodytissues.The NESTOMAT 6050 (6100 Version) processes these signals, separatingthe time invariant parameters (tissue thickness, skin color, lightinten-sity and venous blood) from the time variant parameters (arterialvolume and SaO 2 ) to identify the pulse and calculate the oxygen saturation.Oxygen saturation calculations can be performed because bloodsaturated with oxygen predictably absorbs less red light than oxygendepleted blood.Since measurement of SaO 2 depends on a pulsating vascular bed, anycondition wich restricts blood flow, such as use of a blood pressure cuffMAN-012Sept.00Ed. 1 / Rev. 3NESTOMAT 6050
