Abstract
The invention relates to a patient measurement device, especially to a pulse oximeter, provided with multiple sensors. In order to reduce the hardware required by a measurement performed through the multiple sensors, a repeating drive pulse sequence is generated, which contains drive pulses for the emitter elements of the plurality of sensors. Furthermore, each drive pulse of the sequence is supplied to a corresponding emitter element and sensor-specific detectors connected in parallel are employed to produce an electric reception signal received at the measurement device.
