Near Infrared Spectroscopy: A Light into Patient Safety? - Abstract
Near infrared spectroscopy (NIRS) is a noninvasive monitor that can be used with clinical skill to help determine cerebral oxygen supply and demand balance even during times when pulsatile flow is absent. Patients for cardiac surgery are at risk for significant post-operative cognitive dysfunction. High flow rates during cardiopulmonary bypass is a risk factor for embolization, while low flows may produce insufficient MAPs to maintain cerebral perfusion. Interventions based on NIRS data has proven beneficial. Other high risk patient populations stand to benefit from using the technology as well. NIRS may help to guide the clinician producing shorter hospital stays and a decrease in post-operative cognitive dysfunction.
