Portable device with multiple integrated sensors for vital signs scanning

A non-invasive method of measuring vital signs with a portable multi-sensor vital signs scanner, the non-invasive method of measuring vital signs comprising:

• applying the portable multi-sensor vital signs scanner to a user's body in a first usage configuration for a first measurement period, wherein the first usage configuration includes pressing one electrode of the vital signs scanner with the user's finger while another electrode of the vital sign scanner is pressed against the user's temple;
• measuring a plurality of vital signs data with the vital signs scanner in the first usage configuration;
• applying the portable multi-sensor vital signs scanner to the user's body in a second usage configuration for a second measurement period, wherein the second usage configuration includes pressing the vital signs scanner against the user's chest;
• recording sound using a microphone of the vital signs scanner when the vital signs scanner is in the second usage configuration;
• measuring data related to motion of the user's chest using an accelerometer of the vital signs scanner when the vital signs scanner is in the second usage configuration;
• providing feedback to the user in response to detecting one or more noise signatures based on the data from the accelerometer, wherein the feedback includes providing an indication to the user to modify at least one of a gripping or a positioning of the vital signs scanner;
• using data from the accelerometer to make an initial determination of a respiration rate of the user, the respiration rate including a maximum inhalation time point and a maximum exhalation time point;
• determining an alternate maximum inhalation time point and an alternate maximum exhalation time point based on at least the maximum inhalation time point, the maximum exhalation time point, and the recorded sound;
• and
• determining a final respiration rate based on at least the maximum inhalation time point, the maximum exhalation time point, the alternate maximum inhalation time point.
