The application of respiratory muscle training to competitive rowing [PDF]

, 2010
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Respiratory muscle training (RMT) has been shown to improve exercise tolerance during a wide range of exercise modalities and durations of activity ...

Excessive gas exchange impairment during exercise in a subject with a history of bronchopulmonary dysplasia and high altitude pulmonary edema [PDF]

, 2007
A 27-year-old male subject (V(O2 max)), 92% predicted) with a history of bronchopulmonary dysplasia (BPD) and a clinically documented case of high altitude pulmonary edema (HAPE) was examined at rest and during exercise.

Ventilatory Limitation of Exercise in Pediatric Subjects Evaluated for Exertional Dyspnea

Frontiers in Physiology, 2019
Purpose: Attribution of ventilatory limitation to exercise when the ratio of ventilation (V˙E) at peak work to maximum voluntary ventilation (MVV) exceeds 0.80 is problematic in pediatrics. Instead, expiratory flow limitation (EFL) measured by tidal flow-

Validation of new marker of fluid responsiveness based on Doppler assessment of blood flow velocity in superior vena cava in mechanically ventilated pigs

Intensive Care Medicine Experimental, 2018
Background We studied a novel approach for the evaluation and management of volemia: minimally invasive monitoring of respiratory blood flow variations in the superior vena cava (SVC). We performed an experiment with 10 crossbred (Landrace × large white)

Reference value for expiratory time constant calculated from the maximal expiratory flow-volume curve

BMC Pulmonary Medicine, 2019
Abstract Background The expiratory time constant (RC EXP ), which is defined as the product of airway resistance and lung compliance, enable us to assess the mechanical properties of the respiratory system in mechanically ...

Padrões ventilatórios na espirometria em pacientes adolescentes e adultos com fibrose cística Respiratory patterns in spirometric tests of adolescents and adults with cystic fibrosis

Jornal Brasileiro de Pneumologia, 2009
OBJETIVO: Avaliar os padrões dos distúrbios ventilatórios observados na espirometria em pacientes com fibrose cística (FC) e suas relações com a gravidade funcional e com o comportamento dos fluxos máximos expiratórios a baixos volumes.

Seasonal change in maximal expiratory flow-volume pattern in patients with Japanese cedar pollenosis. [PDF]

, 1993
Fifteen patients with Japanese cedar pollenosis were examined for lower airway function. Flow-volume patterns obtained from flow-volume and volume-time curves during the pollen season (March) and outside of the pollen season (June) were evaluated.
