Measurement apparatus includes sensors configured to generate signals associated with physiological parameters and adapted to be coupled to tissue comprising blood and to communicate signals associated with the parameters to feedback control circuitry capable of generating physiological information from the signals. A software application is configured to operate on a control system capable of receiving the physiological information and configured to receive voice input signals and manually entered input signals. The control system includes a touch-screen, a proximity sensor, circuitry for obtaining movement information from a positioning sensor, a mechanical system having actuators, and a wireless transmitter to transmit the physiological information over a wireless link to a host. The host is configured to generate status information from the data and includes a memory storage device for recording the status information and a communication device communicating the status information to display output devices that may be located remotely.
