Estimating Airway Resistance from Forced Expiration in Spirometry

Applied Sciences, 2019
Spirometry is the gold standard to detect airflow limitation, but it does not measure airway resistance, which is one of the physiological factors behind airflow limitation. In this study, we describe the dynamics of forced expiration in spirometry using

Simple snoring: Not quite so simple after all? [PDF]

, 2014
Simple snoring (SS), in the absence of obstructive sleep apnoea (OSA), is a common problem, yet our understanding of its causes and consequences is incomplete.

D-4F, an apoA-1 mimetic, decreases airway hyperresponsiveness, inflammation, and oxidative stress in a murine model of asthma[S]

Journal of Lipid Research, 2011
Asthma is characterized by oxidative stress and inflammation of the airways. Although proinflammatory lipids are involved in asthma, therapies targeting them remain lacking. Ac-DW F KA F YDKVAEK F KEA F NH2 (4F) is an apolipoprotein (apo)A-I mimetic that

On the Advantages of Specific Airway Resistance [PDF]

Pediatric Research, 1978
The specific airway resistance (SRaw) is a relatively precise parameter of bronchial quality and in normal children its relation with body length, although very significant (P less than 0.001), is so poor that it can safely be disregarded (Fig. 4). Also the dispersion around the mean value remains stable at any body size (Fig. 4).

The Effects of Aerosol Drug Delivery on Airway Resistance through Heat-Moisutre Exchangers

, 2009
Introduction: The use of heat moisture exchangers (HMEs) is becoming more popular with many institutions delivering aerosolized medications between the HME and the endotracheal tube of patients being mechanically ventilated.

α-Bisabolol alleviates diesel exhaust particle-induced lung injury and mitochondrial dysfunction by regulating inflammatory, oxidative stress, and apoptotic biomarkers through the c-Jun N-terminal kinase signaling pathway

Frontiers in Pharmacology
IntroductionExposure to particulate matter ≤2.5 μm in diameter (PM2.5) is associated with adverse respiratory outcomes, including alterations to lung morphology and function.

The Role of Impulse Oscillometry in Evaluating Disease Severity and Predicting the Airway Reversibility in Patients With Bronchiectasis

Frontiers in Medicine, 2022
BackgroundImpulse oscillometry (IOS) can be used to evaluate airway impedance in patients with obstructive airway diseases. Previous studies have demonstrated that IOS parameters differ between patients with bronchiectasis and healthy controls.

Mechanisms and Management of Obstructive Sleep Apnea: A Translational Overview [PDF]

Clinical and Experimental Otorhinolaryngology
Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent episodes of upper airway obstruction during sleep, resulting in apnea and hypopnea.

The Upper Airway Resistance Syndrome [PDF]

Respiration, 2012
Obstructive sleep apnea syndrome has been recognized as a major public health problem. Both its cardiovascular and metabolic comorbidities and symptoms motivate for an accurate diagnosis and appropriate treatment. The main stimulus associated with obstructive sleep apnea (OSA) and explaining deleterious consequences is intermittent hypoxia.
