Forced Expiratory Time: a Simple Test for Airways Obstruction.
Diabetic Retinopathy-Scott et al. JOUM" haziness of the media in a large proportion of diabetics made it difficult to visualize the capillaries in this study. Although, in Fig. 6 B, an arterial injection of fluorescein has shown up zones of capillary closure alongside arteries and scattered small areas of capillary closure (Ashton, 1953), we have been able to discern this phenomenon in only thr...
متن کاملBronchial obstruction and reversibility in children: inspiratory or expiratory resistance?
Assessing bronchial obstruction and reversibility is of help in diagnosing asthma. The forced oscillation technique (FOT) has gained popularity in children since minimal cooperation is required. Owing to the fact that measurements are performed during tidal breathing, the upper airway may significantly impact on the respiratory resistance (Rrs) [1, 2]. The glottic aperture narrows during tidal ...
متن کاملExpiratory flow limitation and obstruction in the elderly.
Elderly people commonly suffer from dyspnoea, which may stem from expiratory flow limitation (EFL). The relationship between EFL, as assessed by the negative expiratory pressure method and spirometric indices, was investigated in an elderly French population. Subjects, aged 66-88 yrs, filled in socio-demographic and standardised questionnaires, which dealt with: medical history, smoking status ...
متن کاملDeterminants of expiratory airflow in patients with chronic airways obstruction.
This paper examines the relationship between the intrathoracic and bronchial pressures and the flow time course during forceful expiration in patients with severe chronic airways obstruction and tracheobronchial collapse. After an initial peak flow, the flow rate (V) of forceful expirations usually fitted the patient's maximum expiratory flow volume (MEFV) curve. The great reduction in flow aft...
