Heredity of supraglottic exercise-induced laryngeal obstruction
Respiratory symptoms on exertion, such as shortness of breath and wheezing, are commonly associated with asthma, but might also arise from the larynx [1–3]. In recent years, the emergence of exercise laryngoscopy [4] has led to a better understanding of laryngeal movement during exercise, and inspiratory supraglottic collapse on exertion has been established as a common cause of exertional brea...
متن کاملBronchial or Laryngeal Obstruction Induced by Exercise?
A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs) after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs...
متن کاملPrevalence of exercise-induced bronchoconstriction and exercise-induced laryngeal obstruction in a general adolescent population.
BACKGROUND Exercise-induced respiratory symptoms are common among adolescents. Exercise is a known stimulus for transient narrowing of the airways, such as exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO). Our aim was to investigate the prevalence of EIB and EILO in a general population of adolescents. METHODS In this cross-sectional study, a questi...
متن کاملPhysiological mechanisms of dyspnea during exercise with external thoracic restriction: role of increased neural respiratory drive.
We tested the hypothesis that neuromechanical uncoupling of the respiratory system forms the mechanistic basis of dyspnea during exercise in the setting of "abnormal" restrictive constraints on ventilation (VE). To this end, we examined the effect of chest wall strapping (CWS) sufficient to mimic a "mild" restrictive lung deficit on the interrelationships between VE, breathing pattern, dynamic ...
متن کاملNeural respiratory drive in obesity.
BACKGROUND The load imposed on ventilation by increased body mass contributes to the respiratory symptoms caused by obesity. A study was conducted to quantify ventilatory load and respiratory drive in obesity in both the upright and supine postures. METHODS Resting breathing when seated and supine was studied in 30 obese subjects (mean (SD) body mass index (BMI) 42.8 (8.6) kg/m(2)) and 30 nor...
