Figure 2

Screen shots comparing the scoring montages used for scoring with typical PSG signals (upper) and with load cell breathing signals (lower). The screen shots were taken from the same 120 seconds for both scoring results from one patient. The nasal pressure, oral-nasal thermistor, chest belt, and abdominal belt are colored purple in the PSG scoring montage (upper), and the load cell breathing signals are similarly colored purple in the load cell scoring montage (lower). The load cell tracing “All_Sum_HP” is the summation of all the load cells, and the “COP_Y_HP” is the center of pressure load cell signal. The purple, horizontal boxes in both cases indicate the locations of scored respiratory events.
