Noninvasive Technique to Monitor the Pressure under a Cast: A Mobile Application-Friendly Bluetooth Pressure Sensor

Figure 3

Three categories of skin-cast contact surface pressure levels in the application. (a) The first category is the “normal pressure category” with pressure values of 0–50 mmHg and is shown in “green.” (b) The second category is defined as pressure values of 50–75 mmHg, indicating increased pressure and a moderate risk of developing compartment syndrome, and is indicated by “yellow.” (c) The third category is defined as pressure values > 75 mmHg, indicating increased pressure and a high risk of developing compartment syndrome, and is indicated by “red.”
