Airway Resistance during Esophageal Phonation
Journal of Speech and Hearing Disorders, 1982Prosthesis airway resistance calculations were completed for five Blom-Singer prostheses and esophageal source airway resistance estimated were made of five laryngectomized patients using the Singer-Blom voice restoration method. Airway resistance of the Blom-Singer prostheses ranged from 46 to 121 cmH 2 O/LPS ...

The Upper Airway Resistance Syndrome
Chest, 1999The upper airway resistance syndrome (UARS) is a recently described form of sleep-disordered breathing in which repetitive increases in resistance to airflow within the upper airway lead to brief arousals and daytime somnolence. This review will first describe the chronological progression of our understanding of UARS within the broader context of ...

Nasal surgery and airway resistance
The Laryngoscope, 1979AbstractThis study investigates the effects of surgery and bronchodilatation on nasal and pulmonary resistance. The plethysmograph is evaluated as a clinical tool for nasal flow studies. The method of adapting the plethysmograph to measure nasal resistance is presented.Discriminant Function Analysis considers the effects of surgery and ...

Atropine, Neostigmine and Airway Resistance
Acta Anaesthesiologica Scandinavica, 1974This study was performed to find out whether the two common modes of administration of atropine and neostigmine used for reversal of neuromuscular blockade ‐ neostigmine preceded by atropine, or both drugs given simultaneously ‐ differ in their effects on airway resistance.Peak expiratory flow (PEF) and airway resistance (Raw) were measured in eight ...

Extrathoracic airway resistance in man
Journal of Applied Physiology, 1961Simultaneous extrathoracic and intrathoracic flow resistance was measured in 19 unanesthetized subjects during mouth breathing. Lateral intratracheal pressure was recorded from a needle introduced 2 cm below the larynx. The intratracheal-oral pressure gradient was recorded during various respiratory maneuvers.

Comparative Measurements of Airway Resistance
Respiration, 1975Three different ways to calculate airway resistance with the whole body plethysmograph during spontaneous breathing and the MBC maneuver were tested on normal subjects and patients with obstructive airway disease. The 'effective resistance values' calculated by applying periodic electric current theory correlate well with a linear interpolation of the ...

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

Corticosteroid Resistance in Airway Disease
Proceedings of the American Thoracic Society, 2004Resistance to the antiinflammatory effects of corticosteroids is very uncommon in asthma but common in chronic obstructive pulmonary disease. Recent understanding of the molecular mechanisms involved in the antiinflammatory actions of corticosteroids has revealed that there are several possible mechanisms for corticosteroid resistance.
