Impedance pneumography: noise as signal in impedance cardiography.
Thoracic impedance is modulated by events within the respiratory cycle, which represents a source of "noise" in impedance cardiography. Respiration itself, however, is a physiological rhythm of interest to psychophysiologists. We report here methods and validation for deriving impedance pneumographic measures of respiration from impedance cardiography signals, based on standard tetrapolar band ...
متن کاملRespiration Rate Measurement Based on Impedance Pneumography
This document discusses the use of impedance pneumography as a technique to measure respiration rate. The generation of high-frequency ac current source is described, and the issues related to delay in modulated signal and finite transition times of carriers are addressed. The report also includes descriptions of potential implementations of a respiration rate measurement system using the ADS12...
متن کاملRespiratory Monitoring: Advantages of Inductive Plethysmography over Impedance Pneumography
Inductive plethysmography and impedance pneumography are two non-invasive technologies for measuring respiratory function. The following report describes the advantages of inductive plethysmography, which include greater accuracy and sensitivity; the ability to assess thoracoabdominal coordination; and the minimization of motion artifact. Together, these properties make inductive plethysmograph...
متن کاملGraphene electrodes for long-term impedance pneumography - a feasibility study
Typical disposable Ag/AgCl electrodes have potential drawbacks from a long-term measurement perspective. Particularly, they can cause an allergic reaction of the skin and can detach in case of sweating during physical activity or sleep. As they are disposable, the electrodes cannot be removed for cleaning. They must be connected to a device with separate cables, which adds to the wearer’s disco...
متن کاملAssessment of calibration methods on impedance pneumography accuracy.
The aim was to assess accuracy of tidal volumes (TV) calculated by impedance pneumography (IP), reproducibility of calibration coefficients (CC) between IP and pneumotachometry (PNT), and their relationship with body posture, breathing rate and depth. Fourteen students performed three sessions of 18 series: normal and deep breathing at 6, 10, 15 breaths/min rates, while supine, sitting and stan...
