Point of Care Device for Confirmation of Intravenous (IV) Catheter Placement and Measurement of Peripheral Venous Pressures
Vanderbilt researchers have designed a low-cost, point-of-care device that non-invasively monitors peripheral venous pressure (PVP) to ensure proper placement of peripheral intravenous (PIV) catheters in patients. Use of this device will ensure proper administration of intravenous fluids and intravenous drugs. The device will also prevent the administration of fluid and potent pharmacologic agents into the subcutaneous tissue or fascia, commonly known as "IV infiltration."
In order to prevent improper placement or displacement of the PIV catheter, Vanderbilt researchers have designed a portable device that analyzes PVP and venous pressure waveforms to both confirm and monitor proper PIV placement. The portable device continually measures and monitors PVP and provides analysis of venous pressure waveforms. An important aspect of the device is the ability to measure both the PVP and the fluid pressure from the PIV line simultaneously and dynamically while fluid flow continues to the patient. The invention may also be used for non-invasive monitoring of intravascular volume or evaluation of the effectiveness of volume resuscitation.
Advantages• Functions as a low-cost and cost-effi cient method to prevent infiltration complications
• Provides point-of-care testing which is portable and easy to use
• Requires minimal training for implementation
• Represents more advanced monitoring capabilities compared to existing absolute PVP pressure monitoring methods
• Reduces the need for invasive central venous access for monitoring purposes
• Pressure can be monitored directly with a Smartphone (iPhone or Droid, e.g.) or a dedicated monitor
A prototype device is being tested in an IRB-approved research study at Vanderbilt University. Vanderbilt University has a pending patent application for this technology.
