ReviewCerebral perfusion monitoring in acute care surgery: current and perspective use.
The technology near infrared spectroscopy (NIRS) has been utilized extensively in several clinical settings and one of which is in cerebral oximetry. This review will provide information on the technology, clinical applications and algorithm to follow when desaturation occurs. ⋯ The review will cover the technology of near infrared spectroscopy, cerebral oximetry and the utilization of cerebral oximetry in each clinical setting. Expert commentary: Cerebral oximetry provides a noninvasive measure of cerebral oxygenation, which when persistently declining, can serve as a warning sign of hemodynamic or metabolic compromise intraoperatively or a predictor of postoperative cognitive dysfunction. Although useful, the cerebral oximetry readings must be interpreted in the context of other clinical information. When cerebral desaturation is confirmed, an algorithm should be followed in an attempt to increase oxygen delivery to the brain and/or decrease cerebral metabolic rate of oxygen.

ReviewMobile health in cardiology: a review of currently available medical apps and equipment for remote monitoring.
Recent developments in implantable cardioverter-defibrillators (ICDs) and smartphone technology have increased the possibilities for remote monitoring. It is the purpose of this review to give an overview of these new possibilities. ⋯ Remote monitoring in ICD allows for early detection of lead fractures and remote follow-up of patients. Possible limitations are the lack of standardization and the possible unsafety of the data stored on the ICD. Secondly, remote monitoring of health parameters using smartphone compatible wearables and smartphone medical apps is addressed. Possible limitations include the fact that the majority of smartphone apps are unregulated by the regulatory authorities and privacy issues such as selling of app-generated data to third parties. Lastly, clinical studies with smartphone apps are discussed. Expert commentary: New technologies in ICDs and smartphones have the potential to be used for remote monitoring. However, unreliability of smartphone technology, inadequate legislation and lack of reimbursement impede implementation.
