Notes
  • nibpSNAPSHOT non-invasively measures oscillometric blood pressure and 7-lead ecg (6 standard leads, 1 chest lead) separately or concurrently in restrained dogs and primates during toxicology studies.

    Unlike other 'black box' systems, nibpSNAPSHOT allows immediate review of waveforms and their analysis. The user also has the ability to immediately trigger another measurement cycle or adjust inflation pressure and deflation speed.

2 solutions for noninvasive blood pressure measurement

  1. 1. 2 solutions for noninvasive blood pressure measurement emkaPACK & nibpSNAPSHOT smart tools – swift services – sharp research www.emka.frwww.emka.fr
  2. 2. noninvasive blood pressure measurement A overview B emkaPACK C nibpSNAPSHOT D software analysiswww.emka.fr

  4. 4. what is NIBP?a noninvasivemethod formeasuring the bloodpressure oflaboratory animals(dog, primates, etc.)www.emka.fr
  5. 5. how does it work?emka TECHNOLOGIES’ noninvasive bloodpressure systems are based on theoscillometric technique: pressure ismeasured from a cuff around a limb or thetail that is inflated to block blood flow thendeflated slowlywww.emka.fr
  6. 6. what is analyzed? cuff pressure timewww.emka.fr

  22. 22. how is analysis performed?ecgAUTOdetects inflation cyclesapplies hi-pass filterselects valid blood pressure pulsesproduces bell shaped amplitude curvecomputes mean, systolic and diastolicpressure valueswww.emka.fr
  23. 23. what are the challenges for a successfulanalysis?when signal is noisy the algorithm picks pulsesthat correspond to blood pressure beats andignores artefactsfor greater efficiency, the software applies anumber of criteria and rejects unreliable orspurious resultspresent experience (around 1000 hours of datafrom 40 dogs) indicate that from 70 to 95% ofinflation cycles produce reliable datawww.emka.fr
  24. 24. examples of good and poor quality signalspulses from noisy zones are ignoredwww.emka.fr
