This study aims to develop a method for estimating tissue Perfusion Index using Near-Infrared Spectroscopy (NIRS) parameters. By accurately predicting the perfusion index from NIRS parameters (NPI), the study seeks to explore NIRS potential clinical implications in enhancing patient monitoring and aiding in clinical decision-making. The study includes two measurement protocols. In Protocol 1, a tourniquet will be wrapped around your right arm and NIRS sensors will be used to measure blood flow and oxygen levels while adjusting pressure in specific intervals over several sessions. In Protocol 2, (performed once on your left arm) similar steps will be followed. Both protocols involve applying various amounts of pressure while the NIRS sensors collect data. If you experience discomfort, notify the team immediately. This process helps to gather crucial information about your blood flow and oxygen levels. Protocol 1 will be conducted on 3 different days, while Protocol 2 will be performed once after Protocol 1, on the 3rd day.
Why should you participate in this study?
There is no direct benefit for the participant. However, participation in this study will help us to better understand how NIRS can be used in perfusion monitoring and lead to applications in clinical practice.
You may be able to participate in this study if you:
You are invited to participate in this research study if you are a healthy individual between the ages of 19-and 70 years old.
You will not be eligible to participate in this study if you:
Have cardiovascular, neurological or respiratory conditions, or, if you have any skin sensitivities/allergies to NIRS sensors or adhesive materials.
Time commitment: The protocols will be conducted on three consecutive days, 15 minutes on the first/second day and 30 minutes on the final day for a total of 60 minutes of your time.
Compensation for participation: N/A.
This study will take place at: ICORD/Blusson Spinal Cord Centre (818 West 10th Avenue, Vancouver).
