1. The regional distribution of ventilation was studied with a 133Xe wash-out technique both after rebreathing and after intravenous injection of the isotope in six patients with chronic obstructive lung disease. Measurements were performed in the sitting position during spontaneous and augmented abdominal breathing respectively. The contribution to ventilation of the rib-cage and abdomen was m...

BACKGROUND Early detection of respiratory overload is crucial to mechanically ventilated patients, especially during phases of spontaneous breathing. Although a diversity of methods and indices has been established, there is no highly specific approach to predict respiratory failure. This study aimed to evaluate acceleration sensors in abdominal and thoracic wall positions to detect alterations...

INTRODUCTION We hypothesized that mechanical ventilation per se increases abdominal edema and inflammation in sepsis and tested this in experimental endotoxemia. METHODS Thirty anesthetized piglets were allocated to one of five groups: healthy control pigs breathing spontaneously with continuous positive pressure of 5 cm H2O or mechanically ventilated with positive end-expiratory pressure of ...

Speech motor control emerges in the neurophysiologic context of widely distributed, powerful coordinative mechanisms, including those mediating respiratory function. It is unknown, however, whether developing children are able to exploit the capabilities of neural circuits controlling homeostasis for the production of speech and voice. Speech and rest breathing were investigated in eleven 15-mo...

A variety of chest physiotherapy techniques are used following abdominal and thoracic surgery to prevent or reduce post-operative complications. Breathing techniques with a positive expiratory pressure (PEP) are used to increase airway pressure and improve pulmonary function. No systematic review of the effects of PEP in surgery patients has been performed previously. The purpose of this system...

This study aims to determine the effective breathing exercise technique on respiratory function in post-abdominal surgery patients. research design is a literature using search engines Science Direct, EBSCO, Wiley Online, and Clinical Key. The results showed similarities interventions applied, namely exercises with various techniques such as deep exercise, coughing activity, balloon blowing pur...

Some smartphones have the capability to process video streams from both the front- and rear-facing cameras simultaneously. This paper proposes a new monitoring method for simultaneous estimation of heart and breathing rates using dual cameras of a smartphone. The proposed approach estimates heart rates using a rear-facing camera, while at the same time breathing rates are estimated using a non-...
