in pulmonary monitoring the processing and interpretation of esophageal pressure signals is often complicated by strong cardiogenic oscillations (CGO). In this paper, we descibe an adaptative filter that reduces CGO based on simultaneous recordings of the electrocardiogram. The algorithm is tested in a computer simulation and on patients data. In simulation, a reduction of the mean squared errors introduced by the CGO by 87% is achieved. In patients data, the filter reduces the power in Pes in a ± 0.25Hz band around the hearth rate by 76%

Abstract
in pulmonary monitoring the processing and interpretation of esophageal pressure signals is often complicated by strong cardiogenic oscillations (CGO). In this paper, we descibe an adaptative filter that reduces CGO based on simultaneous recordings of the electrocardiogram. The algorithm is tested in a computer simulation and on patients data. In simulation, a reduction of the mean squared errors introduced by the CGO by 87% is achieved. In patients data, the filter reduces the power in Pes in a ± 0.25Hz band around the hearth rate by 76%File in questo prodotto:
