A near-infrared spectroscopy (NIRS)probe is placed in a trauma patient during the resuscitation phase to:
A) assess severity of metabolic acidosis.
B) determine intraperitoneal bleeding.
C) determine tissue oxygenation.
D) prevent complications of over-resuscitation.

Question

Quizplus · Accepted Answer

NIRS is a continuous noninvasive technology that uses principles of light transmission to measure skeletal muscle oxygenation as an indicator of shock.Low oxygenation levels detected by NIRS may suggest metabolic acidosis but requires laboratory analysis.Poor tissue perfusion determined through NIRS requires further evaluation of causes of shock,including intraperitoneal bleeding.NIRS would not be helpful in determining complications associated with over-resuscitation.
