VS-800: Configurable vital signs monitor; measures SpO2, PR, NIBP, and temperature; powered by AC mains or internal battery (lead-acid/lithium); features LCD/LED display, menu-driven interface, and optional thermal recorder. Used in healthcare facilities by clinicians; provides audible/visual alarms for parameter violations. Both devices utilize existing sensor technology to provide real-time physiological data for clinical decision-making. ## Clinical Evidence Clinical study conducted according to ISO9919 to validate SpO2 performance following probe modification. Bench testing included design change analysis, biocompatibility, performance, and safety/EMC testing. Results demonstrated devices meet design specifications and perform equivalently to predicates. ## Technological Characteristics PM-50: Portable, battery-powered. VS-800: AC/battery-powered (lead-acid/lithium). Both use two-wavelength (red/infrared) optical sensing for SpO2. VS-800 includes NIBP and temperature modules. Connectivity via patient cables; optional thermal recorder. Software-based parameter processing and alarm management. ## 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 - PM-50 Pulse Oximeter ([K061442](/device/K061442.md)) - VS-800 Vital Signs Monitor ([K063055](/device/K063055.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The PM-50 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 LCD screen. PM-50 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 LCD screen. VS-800 Vital Signs Monitor: The VS-800 Vital Signs Monitor is a prescription device intended for use by health care professionals. And the device is capable of operation from an external AC mains powers source or an internal battery including rechargeable lead-acid battery and lithium battery. The device uses the same or similar technology and materials as the predicate devices, see Legally Marketed Predicate Devices listed above. The VS-800 Vital Signs Monitor is a configurable monitor with options selected by customer preference. Device's options including module configuration and language setting are configured at the time the monitor is manufactured. Options may be upgrade via upgrade port by the manufacturer. The monitor also provides customer with the convenient operating control and human-machine interface (HMI). All of the patient cable connections are located on the monitor. The LCD and LED display patient information and the menu provides single control operations of all main functions. Operator can adjust parameter alarm settings that give audible and visual indication when a violation occurs. The VS-800 provides option for printing information by a thermal recorder. This monitor has the following parameters measurement functions: - V SpO2 measurement: pulse oxygen saturation (SpO2), pulse rate (PR), and SpO2 plethysmogram. - イ NIBP measurement: systolic pressure (S), diastolic pressure (D), mean pressure (M), and pulse rate (PR). - V Rectal / oral / axillary TEMP measurement: temperature (TEMP). {2}------------------------------------------------ ## Intended Use: The PM-50 Pulse Oximeter is a non-invasive, spot-check, oxygen saturation and pulse rate monitor. It operates only on battery power using existing PM-50 disposable and reusable sensors labeled for patients ranging from neonates to adults. The VS-800 Vital Signs Monitor is used to monitor physiologic parameters including SpO2, PR and NIBP, and to measure Temperature parameter on adult, pediatric, and neonatal patients in healthcare facilities by clinical physicians or appropriate medical staff under the direction of physicians. It is not intended for transport or home use. # Comparison of Technological Characteristics: The PM-50 Pulse Oximeter and VS-800 Vital Signs Monitor employ the same functional technology as the predicate devices. ### Testing: The device modification only involved the addition of SpO2 probes to PM-50 Pulse Oximeter and VS-800 Vital Signs Monitor. Bench testing and clinical study was conducted based on the modification to verify and validate that the PM-50 Pulse Oximeter and VS-800 Vital Signs Monitor met all design specifications and were substantially equivalent to predicate devices. The following quality assurance measures were applied to the devices: - Design Change and Modification Influence Analysis - Biocompatibility Testing - Performance Testing - Safety & Environmental &EMC Testing - Clinical Study according to ISO9919 ### Conclusion: The conclusions drawn from clinical and bench testing of the PM-50 Pulse Oximeter and VS-800 Vital Signs Monitor demonstrate that the devices is as safe, as effective, and performs as well as the predicate devices. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
