Designing and Evaluating Training Systems -Monitoring Displays

Our novel device for monitoring heart rate, blood pressure, respiration rate, and blood oxygen levels must have visual and audible indicators to establish an effective system. Such visual displays may be created using LED lights and LCD screens that can be colored to signify the various ranges of permissible values (Chen et al., 2018). LEDs may serve as warning lights when readings wander too far from the predicted range for any particular measure. An audio signal may warn a medical expert if an abnormality in reading is detected. A blend of tones at various frequencies may be used to discern different qualities.

The program must also consider people’s eyes and hearing functions. When it comes to vision, we shall consider the size of the displays, the contrast between the panels and the backdrop, and the brightness of the LEDs. To detect a sound, we shall consider its frequency, duration, and loudness (Opoku-Baah et al., 2021). It is critical to adjust the LED brightness, frequency, and intensity to be readily visible and audible without becoming overbearing.

Warning signals are critical to the overall setup. The warning signals must stand out among the crowd. The caution signs might be customized to stand out more from the backdrop. Increase the frequency and duration of the warning signals to make them more audible. To be helpful, our unique technology for monitoring vital signs such as heart rate, blood pressure, respiration rate, and blood oxygen levels must employ both visual and auditory indications. Both the visual displays and the auditory signals will be designed with the user’s senses of sight and hearing in mind (Goldstein, 2011). Warning signs will be designed to stand out from the crowd. Because of this configuration, the medical personnel can check patient readings and respond appropriately and closely.

Instructions
Monitoring Displays
You work for a surgical equipment manufacturing company. You are part of a design team developing a new machine to monitor patient heart rate, blood pressure, respiration rate, and blood oxygen levels. Each function should have both visual displays and auditory cues.
