A Clinical Study Used to Estimate Central Venous Pressure Non-invasively Using Occlusion Pressure

Rövid összefoglaló (regiszter, angolul)

The purpose of this study is to collect different measurements using a method called peripheral venous pressure (PVP). PVP checks the pressure in the veins in the arms or legs. It can give doctors a good idea of how well the heart is working, similar to another method called central venous pressure (CVP), which doctors use in hospitals. In this study, the research team will measure PVP in people aged 0-17. The researcher hopes that this data will help doctors understand how PVP measurements relate to health outcomes, which could lead to better ways to diagnose and treat patients in the future. The peripheral venous pressure (PVP) device will be used to non-invasively measure the pressure required to stop blood flow in the forearm, which will indirectly measure the PVP in the forearm. This device is composed of a pressure sensor and a Doppler flow detector that will be connected to a research laptop for data collection. This device will be placed on the forearm. If you agree to be in this study, the study team will monitor the venous flow rate (the amount of blood moving through the veins over a certain period of time) using a Doppler Flow Detector while applying pressure to the vein with a pressure sensor. This will take place on the forearm. The internal jugular vein will be identified and recorded using ultrasound imaging and Doppler sensor. The forearm vein will be identified and marked using ultrasound imaging. Pressure will be applied for 15 seconds, and then stopped and repeated 4 times, making five sets of measurements. The procedure may be repeated in 2-3 additional sessions during the hospital stay, if necessary. Your participation in this study will last approximately 30 minutes. This procedure is for research only and will not affect your regular care. This will occur during your child's stay in the PCICU/PICU. No additional study visits will be required. The following procedures are being performed for research purposes only: Copying information such as your medical history from your medical record; Obtaining non-invasive peripheral venous pressure measurements.
