Lujan, Heidi L.; DiCarlo, Stephen E. – Advances in Physiology Education, 2022
Pulse oximetry has become the standard of care in operating rooms, intensive care units, and hospitals worldwide. A pulse oximeter continuously and noninvasively monitors the functional oxygen saturation of hemoglobin in arterial blood (Sa[subscript O2]). Sa[subscript O2] is so important in medical care that it is often regarded as a fifth vital…

Washburn, Shannon E.; Stewart, Randolph H. – Advances in Physiology Education, 2020
Blood flow through the cardiovascular system is governed by the same physical rules that govern the flow of water through domestic plumbing. Using this analogy in a teaching laboratory, a model of the cardiovascular system constructed of pumps and pipes was used to demonstrate the basic interactions of pressure, flow, and resistance in a regulated…
