Design and Evaluation of a Wearable Smart Blanket System for Monitoring Vital Signs of Patients in an Ambulance

Table 1

Data elements of the wearable smart blanket system.

No.	General specifications of capabilities	Subsets
1	Functional—possibility of inclusion and exclusion into and from the physician assistant system	Registration, inclusion, exclusion
2	Functional—possibility of registering age and gender in the system software by the physician	Entering diagnoses, editing, saving, final approval, submitting therapeutic suggestions
3	Functional—possibility of receiving medical signals by installed sensors and to call out the ambulance technician	Noninvasiveness of sensors, number of sensors, type of sensors, correct location of installation of sensors
4	Functional—possibility of local recording and storage of vital data and obtaining data from sensor systems (portable patient unit) by system software	Documenting and storing signals such as electrocardiograms, respiratory rate, and heart rate
6	Functional—possibility of interpreting and processing vital data	Extracting acceptable knowledge and information, analyzing symptoms, providing instant feedback, and alerting system
7	Physical requirements	Ideal size and weight, flexibility, relative stability, moisture absorption, waterproof
8	Physical requirement—precise location of sensors	Location of SPO2, BP, HR, temp sensors
9	Nonfunctional requirement	Easy maintenance and use, confidentiality, responsiveness, accessibility, encryption, entity authentication
