NCT06828432

Brief Summary

The goal of this study evaluate three novel, Food and Drug Administration (FDA)-approved devices currently used to monitor blood pressure and the amount of blood that the heart pumps during each beat. These devices are the ClearSight (Edwards Life Sciences), CareTaker (CareTaker Medical) and CNAP (CNS Systems). These devices measure blood pressure, how much blood the heart is pumping around the body each minute and on a heartbeat to heartbeat basis and other parameters that can tell the doctor if the patient will benefit from specific treatments. The purpose of this study is to determine the accuracy of these devices. This knowledge will help us understand how investigators can use such non-invasive devices to care for patients at less risk than the devices currently used for such purposes. The main question the study aims to answer is: • What monitor is the most accurate in capturing non-invasive patient data?

Outcome Measures

Primary Outcomes (3)

  • Stroke Volume Variation

    The Stroke Volume Variation (SSV) will be collected continuously for 8 hours using all 3 devices (ClearSight, CareTaker and CNAP). The metric of performance will be the precision, accuracy and concordance assessed using Bland Altman analysis and Pearson's moment analysis comparing SVV from each of the non-invasive monitors with the reference standard obtained from the analysis of the arterial pressure waveform. Measurement of SVV, PPV, Eadyn and CO from non-invasive monitors will be obtained continuously, but the quantity will be recorded at different timepoints including: Baseline, every 30 min after baseline, before each bolus of crystalloid fluid or blood product (within 5 minutes of administration, after each bolus of crystalloid fluid or blood product (within 5 minutes of stopping), before each change in vasopressors or inotropes (within 5 minutes of administration), after each change in vasopressors or inotropes (within 5 minutes of stopping), before changing ventilatory mode.

    8 hours

  • Pulse Pressure Variation (PPV)

    The Pulse Pressure Variation will be collected continuously for 8 hours using all 3 devices (ClearSight, CareTaker and CNAP). The metric of performance will be the precision, accuracy and concordance assessed using Bland Altman analysis and Pearson's moment analysis comparing PPV from each of the non-invasive monitors with the reference standard obtained from the analysis of the arterial pressure waveform. This metric of performance will be reported. The most reliable device will be based on the metric of performance - that is, the most precise, accurate and concordant. Measurement of SVV, PPV, Eadyn and CO from non-invasive monitors will be obtained continuously, but the quantity will be recorded at different timepoints including: Baseline, every 30 min after baseline, before each bolus of crystalloid fluid or blood product (within 5 minutes of administration, after each bolus of crystalloid fluid or blood product (within 5 minutes of stopping), before each change in vasopressors.

    8 hours

  • Arterial Dynamic Elastance (Eadyn)

    The Arterial Dynamic Elastance (Eadyn) will be collected continuously for 8 hours using all 3 devices (ClearSight, CareTaker and CNAP). The metric of performance will be the precision, accuracy and concordance assessed using Bland Altman analysis and Pearson's moment analysis comparing Eadyn from each of the non-invasive monitors with the reference standard obtained from the analysis of the arterial pressure waveform. This metric of performance will be reported. The most reliable device will be based on the metric of performance - that is, the most precise, accurate and concordant. Measurement of SVV, PPV, Eadyn and CO from non-invasive monitors will be obtained continuously, but the quantity will be recorded at different timepoints including: Baseline, every 30 min after baseline, before each bolus of crystalloid fluid or blood product (within 5 minutes of administration, after each bolus of crystalloid fluid or blood product (within 5 minutes of stopping).

Interventions

The CareTaker Vitalstream device is a patented PDA technology and artificial intelligence algorithms derive continuous hemodynamic parameters by analyzing reflective pulse wave analyzes the pulse pressure waveform at 500 times per second, isolates the individual central aortic pulses that give rise to the observed pulse shape, reads central aortic measurements therefore eliminating the effects of hydrostatic pressure, and tracks vascular tone.

The CNAP Monitor provides advanced hemodynamic information from the non-invasive reusable CNAP finger sensor. It supports your Goal Directed Therapy whenever an arterial line is not indicated. Patient-friendly, easy-to-use, cost-efficient. CNAP Monitor offers a unique set of parameters to support your daily routine - all non-invasive \& continuous allowing for perioperative fluid management even in low and moderate-risk surgeries and patients.

The Edwards ClearSight system provides continuous blood pressure and advanced hemodynamic parameters from a noninvasive finger cuff. Continuous data offered by the ClearSight system enables you to proactively optimize perfusion through hemodynamic management.
