Healthy Volunteer Study to Evaluate the Impact of Various Common Interventions on Venous Pressure Signal Captured by PIVA
29. marts 2021 opdateret af: Baxter Healthcare Corporation
Healthy Volunteer Study to Evaluate the Impact of Various Common Interventions on Venous Pressure Signal Captured by Peripheral Intravenous Analysis (PIVA) Technology
Non-invasive sensors have been used in research in the United States (US) to aid in the assessment of a subject's heart rate (HR), respiratory rate (RR) and fluid volume status. This estimate and its trended value over time, when used along with clinical signs and symptoms and other subject test results, can aid in the process of reaching a diagnosis and formulating a therapeutic plan when abnormalities of volume status, or RR are suspected.
Non-invasive sensors like the Peripheral IntraVenous Analysis (PIVA) sensor under development by Baxter and the Deltran blood pressure (BP) transducer, capture waveforms created by physiological mechanisms such as blood flow and breathing. An algorithm is then applied to the captured waveform to give clinicians an idea of hemodynamic (volume) status, and RR.
In this study, the functional robustness (e.g., subjects sitting, elevated leg positions, etc.) of the PIVA algorithm/technology will be demonstrated by evaluating the impact of various common interventions on the venous pressure signal. All subjects will undergo 33 interventions expected to take approximately 4 - 6 hours.

Eksperimentel: IV line with an attached Deltran BP transducer
After device setup, subjects will be guided through a series of manipulations of the IV set while waveforms, pulse rate (PR), respiratory rate (RR) are collected at the start and stop of each test.
At the end of the study, the PIVA algorithm will then be applied to the waveforms and calculated values will be compared with those from bedside monitors to understand the effect of common manipulations on the waveforms and determine most optimal conditions for capturing RR and PR through peripheral IV analysis.
|
An IV line with an attached Deltran BP transducer will be used together with LabChart software to record venous waveforms during various interventions.
These waveforms will be processed using the PIVA algorithm and the calculated values will be compared to those from Nellcor respiratory monitor, Capnograph and cardiac telemetry monitoring.

Signal Quality Index (SQI) Score by Supine, Sitting, Standing Body Positions
Tidsramme: End of interventions #15 (supine for 5 minutes), #17 (sitting for 5 minutes), and #19 (standing for 5 minutes)
|
Ranking of subject body positions (supine, sitting, standing) based upon their impact on the venous waveform signal, from best to worst, based on the PIVA algorithm-derived SQI.
Score on the scale include 0=no signal, 1=poor signal, 2=good signal.
The highest percentage of time with good signal quality will be the best ranked position, and the lowest percentage of time with good signal quality will be the worst ranked position.
