The present disclosure describes systems, apparatus, and methods for collecting biometric data from a patient. In some cases, this biometric data can be collected during the course of an emergency encounter using a medical device. The medical device can also perform other functions, such as monitor patient vital signs, receive and record notes and textual information, communicate with other devices, and/or deliver a therapeutic treatment. The medical device can also be configured to record and/or maintain a patient record, and to embed the patient biometric data into the patient record for use in later confirming and/or determining an identity of the patient. Some embodiments can also collect biometric data relating to one or more caregivers of the patient, and to embed the caregiver biometric data into the patient record. This caregiver biometric data can be used to confirm and/or identify one or more caregivers in a patient record.
