Vital information monitors use the latest sensor technology to provide continuous information. When observing responses to treatment over time, such as in intensive care units where patients need to remain still during treatment or after surgery, fixed bedside monitors that can observe a wide range of vital signs and run on AC power are the way to go. On the other hand, in general wards, many patients are independent and preparing for discharge, and although the risks are reduced, there are cases where a minimum amount of vital information needs to be observed. Taking into account the risks and convenience, portable battery-powered telemetry transmitters are widely used.
Essentially, vital signs monitors are intended to detect upper and lower thresholds and arrhythmias, known as "biological alarms," for the purpose of early detection and early response, but there are also many "technical alarms," which are caused by machines, sensors, or usage. These are called "false alarms" because they are unintended alarms. If false alarms continue, the person gradually becomes desensitized to threats. (The "boy who cried wolf" syndrome)
This time, we focused on the "immediate response to battery replacement alarms" of telemetry transmitters and worked on it. JMP16 was used for the analysis. Fishbone diagrams, random number simulations, control charts, reliability growth, etc. were utilized.
We will report on a series of business improvement activities.
