Measurement of Nasal Resistance Using the Forced Oscillation Method

Nasal airflow resistance measurement: forced oscillation technique versus posterior rhinomanometry.

This study was designed to determine whether nasal airflow resistance (Rn) which is nonlinear during tidal breathing, can be assessed by the forced oscillation (FO) technique. Rn values obtained by the FO technique and extrapolated to 0 Hz (Rn,FO) were compared to those assessed by posterior rhinomanometry at maximal tidal inspiratory flow (Rn,m), at a 0.5 L x s(-1) flow (Rn,F), and at a 1 hPa ...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Automated system for direct measurement and feedback of total respiratory resistance by the forced oscillation technique.

detection of airway partitioning following unilateral nasal stimulations by the forced oscillation technique in rats.

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...

Measurement of total respiratory resistance using oscillation technique.

Clicks, honks, and whoops. D. Pickering (Rad-cliffe Infirmary, Oxford). Three cases are described which were originally diagnosed as having ventricular septal defect, pulmonary stenosis, and innocent prae-cordial honk. These have been reinvestigated using pixie accelerometer, phonocardiographic techniques (Bew et al., 1971). All three have been shown to have clicks which move with posture, Vals...
