Spontaneous Low Frequency Oscillations in Acute Ischemic Stroke – A Near Infrared Spectroscopy (NIRS) Study
Background and purpose: Continuous wave near infrared spectroscopy (NIRS) is a non-invasive bed-side optical method to detect changes in oxygenated (oxyHb) and deoxygenated hemoglobin (deoxyHb) in the outermost layers of the cerebral cortex. Cortical oxyHb low frequency oscillations (LFOs) in the 0.09-0.11 Hz range are affected by changes in cerebral autoregulation (CA), which is altered follow...
متن کاملCerebral tissue oxygen saturation calculated using low frequency haemoglobin oscillations measured by near infrared spectroscopy in adult ventilated patients.
Oxy- (HbO2) and deoxy- (HHb) haemoglobin signals measured by near infrared (NIR) spectroscopy over the human frontal lobes frequently contain respiratory and low frequency oscillations (LFOs). It has been suggested previously that venous oxygen saturation (SvO2) can be calculated from these respiratory oscillations. In this paper, we investigated the use of a Fourier transform based algorithm t...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملDetermining Blood Glucose Concentration using Near Infrared Spectroscopy: Early Findings
Introduction: Diabetes mellitus is one of the diseases that have grown dramatically in today's societies. People with diabetes should continuously measure their blood glucose level. Continuous blood glucose measurement by commonly used methods is painful and difficult. On the other hand, mobile phone can be a useful tool for accessing physicians and telemedicine services more easily. The aim of...
