No results posted yet for this study

Summary

This study aims to evaluate brain death with optical probes. The changes of hemodynamic parameters including oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) were detected by near infrared spectroscopy probes attached on the forehead of patients. A multiple-phase protocol at varied fraction of inspired O2 were utilized during the assessment.

Conditions

  • Brain Death

Interventions

PROCEDURE

Oxygen supply of high-low-high procedure

The protocol consisted of 1-hour resting, 3-minute baseline measurement, half-hour measurement at 60% FIO2 (phase I, high oxygen), half-hour measurement at 40% FIO2 (phase II, low oxygen) and half-hour measurement at 60% FIO2 (phase III, high oxygen).

PROCEDURE

Oxygen supply of low-high-low procedure

The protocol consisted of 1-hour resting, 3-minute baseline measurement, half-hour measurement at 40% FIO2 (phase I, low oxygen), half-hour measurement at 60% FIO2 (phase II, high oxygen) and half-hour measurement at 40% FIO2 (phase III, low oxygen).

DEVICE

Optical monitor for hemodynamic parameter.

Near infrared spectroscopy probes of tow wavelengths were attached on the subjects' foreheat to detect the changes of hemodynamic parameters.
