Description:
The Rossmax Z5 is an automatic blood pressure monitor. The accuracy of its blood pressure measurement technology has yet to be proven to MDR requirements. Blood pressure measurements are taken from the upper arm. With atrial fibrillation detection, it is intended for professional use.
Assessment:
The technology used in the Rossmax Z5, 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.
Recommendations:
| Accuracy Assessment | Recommendation | Basis | |
| BP | Medaval | None | Although equivalence to another device is claimed, this has not been tested to MDR requirements. |
| BP | BIHS (UK and IRL) | Self-measurement (Previous) | Manufacturer declaration of equivalence to the Rossmax CF175 |
| BP | Stride BP | Self-measurement for adults (Preferred) | Equivalence claim without published evidence |
