Abstract

We present the design and test of a portable wireless catheter system combining the simultaneous assessment of the transdiaphragmatic pressure and EMG of the diaphragm. The esophageal catheter includes two micro fabricated pressure sensors and five platinum ring electrodes. The low noise analog front-end features an electrode DC mismatch correction circuitry, a selectable gain (58 dB-97 dB) as well as a high CMRR (80.3 dB). Pressure signals are sampled at 1 kHz while EMG at 4 kHz. The data is transmitted over a wireless Bluetoothreg connection towards a computing host to display the received signals in real time. Testing of the device demonstrates its reliability to process pressure and EMG signals and to be used as a stand-alone respiratory parameters assessment device
