Resistance and Collapse in Bronchial Airways
Clinical Science, 19701. The Forced Expiratory Volume (FEV) was measured in normal persons and patients with obstructive airways disease at mouth pressures from 0 mmHg to levels high enough to prevent air flow altogether by using a Starling resistor at the mouth. 2.

Moderate alcohol ingestion increases upper airway resistance in normal subjects.
American Review of Respiratory Disease, 2015Apnea during sleep has been associated with both increased pharyngeal resistance and nasal obstruction. Alcohol can worsen obstructive sleep apnea, but its influence on pharyngeal resistance and nasal patency has not been evaluated.

Plethysmographic specific airway resistance [PDF]
Paediatric Respiratory Reviews, 2006 sRaw measurements are feasible in children from 2 years of age. sRaw allows clinical monitoring and research during this critical period of growth and development in early life. sRaw measurements promise to bridge the gap of lung function measurements between infancy and school age.

Evaluation of spirometric methods used to assess abnormalities in airway resistance.
American Review of Respiratory Disease, 2015Several tests are in common use for the evaluation of abnormalities of airway resistance. The body plethysmograph, although an accurate and direct instrument for the measurement of airway resistance (1), is not suitable for bedside studies, and its use ...

The Effect of Glucagon on Airway Resistance
The Journal of Clinical Pharmacology, 1975Nine subjects with obstructive airway disease took part in this double-blind study of the effect of glucagon in relieving bronchoconstriction compared with isoproterenol or isotonic saline. Drugs were administered via an in-line intermittent positive-pressure breathing unit. FEV1, MEF, PEF, and nitrogen washout data were evaluated.

A passive quantitative measurement of airway resistance using depth data
Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014The Respiratory Syncytial Virus (RSV) is the most common cause of serious lower respiratory tract infections in infants and young children. RSV often causes increased airway resistance, clinically detected as wheezing by chest auscultation.

Airway Resistance of the Voice Button
Archives of Otolaryngology - Head and Neck Surgery, 1982Airway resistance calculations were completed for Voice Button prostheses. Resistance of these devices ranged from about 285 to 440 cm H2O/L/s, revealing that the opposition these prostheses offer to airflow through them is substantial. In this circumstance, a reduction inthe efficiency with which tracheoesophageal voice is produced would be expected.

Increased upper airway resistance in patients with airway narrowing
British Journal of Diseases of the Chest, 1976The mean air flow resistance of the orolaryngeal (upper) airway was significantly increased in 7 of 11 patients with chronic airway obstruction, when compared with 6 controls. All the patients had noisy respiration with harsh breath sounds audible by auscultation over the larynx.

1975
Publisher Summary This chapter reviews the methods used in measuring airway resistance. Air resistances can be measured by the pressure-flow method, interrupter method, and plethysmograph method. The pressure-flow method is similar to the method of measuring compliance, although flow is plotted against pressure difference between the oesophagus and ...

Oxygen, Isoprenaline and Airways Resistance
Respiration, 1970Airways resistance was measured in six patients with chronic bronchitis before and after the inhalation of 30 % oxygen in nitrogen; after oxygen breathing there was a significant decrease in airways resistance. Measurements of airways resistance were made again in the same patients before and after the inhalation of isoprenaline; this was followed by a
