Welch Allyn Spot Vital Signs (4200B)
The technology used in the Welch Allyn Spot Vital Signs (4200B), to measure blood pressure, has passed in a clinical validation study, in a general population, according to a recognised standard protocol, as published in a peer-reviewed publication. It has also been assessed, in a specific population, according to a non-standard protocol.
