Not for continuously monitoring, ## Device Story G1B Pulse Oximeter is a portable, battery-powered device for spot-check measurement of SpO2 and pulse rate. It uses a two-wavelength (red and infrared) pulsatile system; finger sensor emits light absorbed by arterial blood; photodetector converts light intensity into electronic signals. Signals are processed by internal circuitry to calculate SpO2 and pulse rate, which are displayed on an LED screen. Used in home and clinical settings (surgery, anesthesia, ICU) by clinicians or patients. Output provides physiological data for spot-checking; assists healthcare providers in assessing patient oxygenation status. ## Clinical Evidence Laboratory and clinical testing conducted to verify design specifications, including electrical safety, EMC, and biocompatibility. Results demonstrate compliance with consensus standards. ## Technological Characteristics Portable, battery-powered pulse oximeter. Uses two-wavelength (red/infrared) pulsatile sensing principle. LED display. Digital signal processing of photodetector inputs. Complies with electrical safety and EMC consensus standards. ## Regulatory Identification An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter. ## Predicate Devices - Fingertip Pulse Oximeter MD300I ([K072825](/device/K072825.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The G1B Pulse Oximeter acquires the physiological signals - oxygen saturation (SpO2) and pulse rate (PR). The signals are converted into digital data and processed, and the SpO2 and pulse rate values are calculated and displayed on LED screen. G1B uses a two-wavelength pulsatile system - red and infrared light - to obtain SpO2 based on the different light absorption of oxygenated and reduced hemoglobin. The light source in the finger sensor emits red and infrared light, which are partially absorbed and modulated by the arterial blood pulsation at the sensor site. The photodetector in finger sensor collects and converts the light into electronic signal which is proportional to the light intensity. The electronic signals are sent to the oximeter and processed by the oximeter's circuitry. Thereafter, the SpO2 and pulse rate are obtained and indicated on the LED screen. ## 4 .Testing : Laboratory and Clinical testing was conducted to validate and verify that M700 Handheld Pulse Oximeter met all design specifications, including electrical safety, EMC, biocompatibility, specification. Results of these tests demonstrate compliance to the requirements of all consensus standards #### 5. SE Determination The subject device is Substantially Equivalent (SE) to the predicate device which is US legally market device. Therefore, the subject device is determined as safe and effectiveness. 3-2 {2}------------------------------------------------ # DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
