This study aims to validate near-infrared spectroscopy (NIRS) protocols for measuring oxygen consumption and blood flow in the human forearm.
Thirteen subjects tested at rest and during static isometric handgrip exercise at 10% MVC.
NIRS measurements were compared against strain-gauge plethysmography and blood sampling.
Correlation analysis conducted to assess the relationship between NIRS and plethysmography data.
Significant correlation found between NIRS data and plethysmograph during venous occlusion at rest (r 0.925 - 0.994, P < 0.05) and exercise (r 0.895 - 0.990, P < 0.05).
No correlation observed for calculated blood flow and oxygen consumption values between NIRS and plethysmography/blood sampling.
NIRS demonstrated qualitative monitoring capabilities but struggled with accurate quantification due to variability among subjects.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Randomized trial investigates NIRS measurement accuracy for oxygen consumption and blood flow in subjects, suggesting limited quantification reliability.
