• Tricorder
• Vital signs monitoring
• Medical assessment

The goal of rapid medical assessment (RMA) is to estimate the general health of a patient during an emergency room or a doctor's office visit, or even while the patient is at home. Currently the devices used during RMA are typically "all-in-one" vital signs monitors. They require time, effort and expertise to attach various sensors to the body. A device optimized for RMA should instead require little effort or expertise to operate and be able to rapidly obtain and consolidate as much information as possible. MouthLab is a battery powered hand-held device intended to acquire and evaluate many measurements such as non-invasive blood sugar, saliva and respiratory biochemistry. Our initial prototype acquires standard vital signs: pulse rate (PR), breathing rate (BR), temperature (T), blood oxygen saturation (SpO(2)), blood pressure (BP), and a three-lead electrocardiogram. In our clinical study we tested the device performance against the measurements obtained with a standard patient monitor. 52 people participated in the study. The measurement errors were as follows: PR: -1.7 +/- A 3.5 BPM, BR: 0.4 +/- A 2.4 BPM, T: -0.4 +/- A 1.24 A degrees F, SpO(2): -0.6 +/- A 1.7%. BP systolic: -1.8 +/- A 12 mmHg, BP diastolic: 0.6 +/- A 8 mmHg. We have shown that RMA can be easily performed non-invasively by patients with no prior training.
