Abstract: Described is a portable recorder for use by first-response emergency service personnel while providing care to a human subject. The recorder includes memory for storing data and sensor circuitry for sensing physiological signals through electrodes attached to a human subject and for converting the physiological signals into electrical signals. The recorder also has a transducer for converting sound waves into electrical signals and analog-to-digital converter circuitry for converting the electrical signals corresponding to the physiological signals and the electrical signals corresponding to the sound waves into digital data. A processing unit stores the digital data corresponding to the sound waves and the digital data corresponding to the physiological signals in the memory. The data stored in the memory are transferred to a remote computing system. An application program on that computing system automatically generates a report based on the data transferred from the memory.
