Clinical trials: Perfusion Pressures
Spinal Cord Injuries (SCI), Blood Pressure
AI-Guided Predictions of Blood Pressure Dysregulation Using Perfusion Index as a Novel Biomarker in Persons With Spinal Cord Injury
The goal of this clinical trial is to determine if perfusion index (PI) can reliably predict changes in systolic blood pressure (SBP) in persons with spinal cord injury (SCI) during a cool temperature challenge.

Increase in Intra-abdominal Pressure, Increase in Intracranial Pressure (ICP)
Changes in Cerebral Oxygenation Studies During Laparoscopy Procedure
The motivation results from the fact, that an intra-abdominal pressure is correlated with cerebral perfusion, in a mechanism of reducing venous outflow.
- Conditions
- Increase in Intra-abdominal Pressure, Increase in Intracranial Pressure (ICP), Laparoscopy, Cerebral Perfusion and Oxygenation
- Trial name
- NCT03640741
- Testing
- Laparoscopy
- Volunteers
- 17 people, healthy volunteers welcome

Cerebral Blood Flow, Cerebral Perfusion Pressure
Continous Assessment of Cerebral Autoregulation With Near-infrared Spectroscopy
Cerebral autoregulation can be explained by a tight coupling between oxygen supply and demand of the brain, and is essential to maintain a constant cerebral blood flow (CBF) in the context of changes in cerebral perfusion…
