The Nihon-Kohden Vismo PVM-4000 is a patient monitor. Its blood pressure measurement technology has been proven to be accurate and information regarding the accuracy of its oxygen saturation measurement technology does not appear to be available. Blood pressure measurements and oxygen saturation measurements are taken from the finger. It is intended for bedside patient monitoring.
The technology used in the Nihon-Kohden Vismo PVM-4000, to measure blood pressure, has been compared to a clinically validated device, but the results of the equivalence study have not been published and cannot be verified; nor can the protocol be checked for compliance with (EU) 2017/745 and MEDDEV 2.7/1 rev 4. There appears to be no peer-reviewed clinical validation information available on the technology used in the Nihon-Kohden Vismo PVM-4000 to measure peripheral oxygen saturation.
