About

Investigation of the feasibility of using near-infrared spectroscopy (NIRS) to monitor microvascular function in critically ill patients.

Full description

This is a prospective observational study using non-invasive NIRS for microvascular monitoring in the ICU. The study involves no interventions above standard of care other than the application of the NIRS monitors.

NIRS will be applied to skeletal muscle and the brain longitudinally throughout ICU admission. Vital signs are extracted continuously from the ICU monitor and clinical data are recorded from patient records.

The broad goals of the study are:

1. Determine the feasibility of longitudinal NIRS monitoring in ICU patients
2. Determine the ability to derive patient-specific microvascular metrics using NIRS
3. Explore the relationship between microvascular metrics and ICU mortality

Enrollment: 100 estimated patients
