As part of First Responder and EMT-B training, trainees must learn how to take vital signs--pulse, respiration, skin color/temperature/condition, pupils, and blood pressure. BLS Vital Signs enables trainees to practice on a variety of patients in a variety of scenarios--mimicking what they'll see in practice. Also, the value of computer-based training has been an increased ability to allow trainees to practice skills at their own pace, at the time and location of their choice and with appropriate feedback and remediation.  Anyone training to become a First Responder or EMT-B.
