Computer Software Experts Opine on Programming Error in Defective Ventilator System

Case Overview

This case involves a now-recalled bedside device used to accommodate medical patients with respiratory disorders such as COPD. In this instance a ventilator of this type was being used to supply oxygen to a sleeping patient in an Alaskan hospital who depended on the device for respiration. One week after the device was purchased, it suddenly ceased functioning, but provided no alarm to indicate that anything had gone wrong. As a result, the patient suffocated before assistance could be rendered. It was alleged that the device’s software contained a fatal flaw that allowed the device to cease functioning without providing any kind of alarm.

Questions to the Medical Device expert and their responses
