Discrete-continuous analysis of optimal equipment replacement
In Operations Research, the equipment replacement process is usually modeled in discrete time. The optimal replacement strategies are found from discrete (or integer) programming problems, well known for their analytic and computational complexity. An alternative approach is represented by continuous-time vintage capital models that explicitly involve the equipment lifetime and are described by...
متن کاملContinuous Pulse Oximetry Monitoring in the Inpatient Population
John Smith is admitted late Monday afternoon to the post-surgical ward after a total knee replacement. John is overweight, though not morbidly obese, and has an undeclared history of snoring. He wakes up at 5:30 Tuesday morning with considerable pain; over the next hour he exhausts the opiate supply in his PCA pump, and his nurse inserts a new syringe before her shift ends at 7 a.m. It will be ...
متن کاملCerebral oximetry: a replacement for pulse oximetry?
Cerebral oximetry has been around for some 3 decades but has had a somewhat checkered history regarding application and reliability. More recently several monitors have been approved in the United States and elsewhere and the technique is emerging as a useful tool for assessing not only adequate cerebral oxygenation but also tissue oxygenation and perfusion in other organs.
متن کامل[Cerebral oximetry].
Dr. Frost has no relevant financial conflicts to disclose. C erebral oximetry has been studied for more than 30 years, and has been commercially available to clinicians for more than 2 decades. 1,2 However, whereas pulse oximetry has been a standard of care for decades, only recently has cerebral oximetry been extensively studied and adapted to investigate changes in oxygen delivery to the brai...
متن کاملRoutine Oximetry
Often, advances in medical technology become available on a widespread basis before a controlled scientific experience has accumulated to carefully delineate the indications, uses, and pitfalls of such technology I feel this certainly is the case with pulse oximetry and this issue is partially addressed by the data of Loggan, Kerby and Pingleton (see page 242). The accuracy simplicity and usefu...
