Respiratory failure & ventilation
A novel adaptive filter with a heart-rate-based reference signal for esophageal pressure signal denoising
Authors' conclusion
The proposed technique can effectively eliminate the CGOs from the measured Peso signals in real-time without requiring additional equipment to collect the reference signal.
