Recent advances in understanding the importance of respiratory frequency (f R) as a
sensitive marker of a variety of physiopathological stressors are fostering growing interest in …

Background: Optoelectronic plethysmography (OEP) is a non-invasive motion capture
method to measure chest wall movements and estimate lung volumes. Objectives: To …

Introduction: There has been an exponentially increasing interest in intra-abdominal
hypertension (IAH). The intra-abdominal pressure (IAP) markedly affects the function of the …

Optoelectronic plethysmography (OEP) has been shown to be a reliable method for the
analysis of chest wall kinematics partitioned into pulmonary rib cage, abdominal rib cage …

We used optoelectronic plethysmography to study 11 normal subjects during quiet and deep
breathing, six sedated and paralyzed patients with acute lung injury and acute respiratory …

Although the measurement of pulmonary ventilation by a spirometer or a
pneumotachograph may appear to be a simple procedure, it is much more complicated than …

In this paper, we propose a system that is capable of detecting the breath rate of an athlete.
Furthermore, we investigate equivalences with the tidal volume over the inclination angle of …
