Del Mar Avionics Pressurometer IV
Device Name:
Pressurometer IV
Manufacturer:
Del Mar Avionics Inc., 11-B Marconi, Irvine, CA 92618, UNITED STATES.
Measuring functions:
Blood Pressure and PR
Primary Client Use:
Intended for ambulatory blood pressure monitoring
Measurement Site:
Upper Arm
Measurement Occurrence:
Intermittent measurements at specified intervals or times
Availability:
Obsolete
Description:
The Del Mar Avionics Pressurometer IV is an ambulatory blood pressure monitor. Although its blood pressure measurement technology has been evaluated, it is not possible to base a determination on its accuracy from this research. Blood pressure measurements are taken from the upper arm. It is intended for ambulatory blood pressure monitoring. This device is now obsolete.
Assessment:
The technology used in the Del Mar Avionics Pressurometer IV, to measure blood pressure, has failed 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 general population, according to a non-standard protocol.
Recommendations:
Accuracy AssessmentRecommendationBasis
BP Medaval None When an evaluation is carried out using a non-standard protocol, no inference can be made on accuracy based on a standard protocol.

At rest, non-invasive ambulatory BP monitors are similar in accuracy to clinicians in BP determination but during exercise there are differences among the monitors that make some of them unsuitable for measurements while in motion.
