Physical signs of diffuse airways obstruction and lung distension.

Clinical and physiological associations of some physical signs observed in patients with chronic airways obstruction.

A study of the relation between physical signs and the clinical and physiological pattern of chronic lung disease with obstruction has been carried out on 24 patients with varying degrees of airways obstruction. One sign (the forced expiratory time) was a direct reflection of the obstruction , but a number of other signs which also correlated significantly with the specific airway conductance w...

Mechanical ventilation causes airway distension with proinflammatory sequelae in mice.

The pathogenesis of ventilator-induced lung injury has predominantly been attributed to overdistension or mechanical opening and collapse of alveoli, whereas mechanical strain on the airways is rarely taken into consideration. Here, we hypothesized that mechanical ventilation may cause significant airway distension, which may contribute to the pathological features of ventilator-induced lung in...

Effect of Small Intestine Strangulation Obstruction on Clinical and Histopathological Parameters An Experimental Study in Donkeys

To study clinical and histopathological changes occur within the first 12 hours of strangulating obstruction of the small intestine in equine, twenty five adult donkeys were used in an experimental study. Strangulation obstruction of the small intestine was performed for 3, 6, 9 and 12 hours, respectively. Clinical examination was done before surgery and at 3 hours intervals postoperatively. Af...

Repeatability of physical signs in airways obstruction.

بررسیارتباط بین علائمبالینی آسمو شدت کلینیکیانبا میزان تغییرات در تست‌های عملکردیراه‌های هوایی پرگزیمال و دیستال ریه

Abstract Background & Aims: The peripheral parts of the lung are known as the main place of airflow obstruction in asthmatic patients; but the symptoms of asthma with the location of airway obstruction are still unknown. The aim of this study was to evaluate the association between asthma symptoms and severity of asthma and proximal and distal airways using function tests. Materials &...
