Version: FDA 1.0C5 Fingertip Pulse Oximeter
MD300C5
1.Measurement principle The oximeter is calibrated to display functional oxygen saturation. Principle of the Oximeter is as follows: An experience formula of data process is established taking use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobin(R Hb) and Oxyhemoglobin (O2 Hb) in glow and near-infrared zones. Operation principle of the instrument is Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that two beams of different wavelength of lights (660nm glow and 940nm near infrared light) can be focused onto human nail tip through perspective clamp finger-type sensor. Then measured signal can be obtained by a photosensitive element, information acquired through which will be shown on two groups of LEDs through process in electronic circuits and microprocessor.
2.Precautions for use Operation of MD300C5 may be affected by the use of an electrosurgical unit (ESU). The MD300C5 must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify that nothing is hindering the pulse measurement before replying on the SpO2 measurement. l Do not use the MD300C5 in an MRI or CT environment l Do not use the MD300C5 in situations where alarms are required. The device has no alarms. l Explosion hazard: Do not use the MD300C5 in an explosive atmosphere. l The MD300C5 is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms. l Check the pulse oximeter sensor application site frequently to determine the positioning of the sensor and circulation and skin sensitivity of the patient. l Do not stretch the adhesive tape while applying the pulse oximeter sensor. This may cause inaccurate readings or skin blisters. l Before use, carefully read the manual. l The MD300C5 has no SpO2 alarms, it is not for continuous monitoring, as indicated by the symbol. l Prolonged use or the patient’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours.
