How the Patient Monitor Works
A Patient Monitor works by giving the user clues about how to interact with it. For example, in order to use an alarm or set a temperature, the user needs to see information about the settings on the screen. This is known as affordance. When the user can easily select certain functions, he or she will have a higher chance of using them. Additionally, certain functions on a monitor are not always visible and cannot be directly accessed. Another issue related to visibility is how easily users can activate the monitor's functions. Sensors Sensors in patient monitors enable the continuous monitoring of patient's vital signs to support the decision-making process of medical personnel. Depending on the device, sensors may record body temperature, pulse rate, blood pressure, and other health-related criteria. These sensors can be incorporated into a wearable device or interfaced to a PC through an Arduino microcontroller. A patient monitoring system collects data from different se
