background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...

nasal mucosa has an extraordinary nerve supply with unique geometry that encompasses complex physiology. among these, side-specific predilections to the respiratory and autonomic centers are the interesting issues that have been raised about the consequences of the nasal irritations. the aim of the study was an evaluation of how intranasal stimulation influences lung mechanics and determines wh...

The forced oscillation technique (FOT) allows the measurement of respiratory resistance (Rrs) and reactance (Xrs) and their associated coherence (gamma2). To avoid unreliable data, it is usual to reject Rrs and Xrs measurements with a gamma2 <0.95. This procedure makes it difficult to obtain acceptable data at the lowest frequencies of interest. The aim of this study was to derive expressions t...

INTRODUCTION Detection of smoking effects is of utmost importance in the prevention of cigarette-induced chronic airway obstruction. The forced oscillation technique offers a simple and detailed approach to investigate the mechanical properties of the respiratory system. However, there have been no data concerning the use of the forced oscillation technique to evaluate respiratory mechanics in ...

OBJECTIVE To use the forced oscillation technique to evaluate asthma patients presenting positive bronchodilator responses (confirmed through spirometry) and compare the results with those obtained in healthy individuals. METHODS The study sample consisted of 53 non-smoking volunteers: 24 healthy subjects with no history of pulmonary disease and 29 asthmatics presenting positive bronchodilato...

The method we present here retrospective review and rating of Field Operational Test (FOT) data is designed to capture both the rigor of the laboratory and the ecological validity of the field. It is tailored for studies of driver acceptance of active safety systems. The method makes it possible to leverage expensive FOT data within the confines of the laboratory.
