A hospital is more interested in short-term changes in pressure than it is the actual number. A finger sensor will definitely detect when someonez's pressure crashes or rapidly elevates. Same is true for first responders dealing with trapped people (car crashes). The exact number will be wildly inaccurate given they arent in a proper seated position, but the delta over time is what matters.
