When Breath Is (Not Enough) Air: Let’s Talk about Ventilators
There has been much public discussion about ventilators amidst the COVID-19 pandemic. It is humbling to consider that we, or someone we love, might require one. Most people know something about the benefit of a ventilator when needed; but how well do we really understand the functions and risks of mechanical ventilation? The pandemic presents an opportune time to learn about this. So I posed a series of questions about these machines and the processes involved in using them to a physician, who is a specialist in using ventilators to treat very ill patients. Those questions, and her answers, follow.

Death Certificates and COVID-19
D. Joy Riley, M.D., M.A. Executive Director
One of the tasks assigned to physicians is the completion of death certificates—at least, the portion of death certificates that list cause of death (COD).

The case fatality rate for a particular disease is, basically, the number of persons dying of a disease, divided by the number of persons who have the disease, and multiplied by 100, to give an answer in terms of percentage:
# persons dying of COVID-19 disease X 100 # persons infected with SARS-CoV-2
How is this complicated? ...read more
Flourishing in the Midst of Crisis
Focus on the “Local”
D. Joy Riley, M.D., M.A. Executive Director
It may seem ironic in this time of coronavirus* epidemic that The Tennessee Center for Bioethics & Culture’s theme for 2020 is Human Flourishing. Of course, the theme was chosen before the populace was on such intimate terms with the infection. The theme was also chosen before tornadoes** struck Middle Tennessee; before we knew we would need a hefty dose of encouragement in 2020. In this month’s post, several Tennesseans are featured. From a pharmacist in western Tennessee to a group of studio singers in Music City, these can help us to ...read more
