WT5BZ]To investigate the relationship between the impulse oscillometry method and plethysmogrophy used in measuring airway resistance, Using the two methods to measure the airway resistance and the ventilation data of 158 patients.

The researches on cure of burn combined upper airway obstruction;

Localization diagnosis of upper airway stricture in patients with obstructive sleep apnea syndrome and operative therapy;

Objective To reconstruct a 3D model of upper airway and investigate characteristics of airflow in upper airway.

The fibre endoscopic photo were taken on palate and lingua region upper airway at normal breath and -40cmH2O upper airway negative pressure in doing Muller maneuver, respectively.

Numerical simulation of micro-particle movement and deposition in human upper respiratory tract;

Research on effects of sports to immunity system and upper respiratory tract;

Retrospective analysis of 305 cases of mycotic infections in upper respiratory tract;

Based on this view, this paper analyzes the suitability of protective respirators to human body, and systematically puts forward such ergonomic problems as seal, respiratory resistance, dead space and field of vision about protective respirators at the angle of human facial features and bio-mechanical characteristics of head and neck.

Objective:To study the clinical significance of the respiratory resistance and diffusion capacity in lung cancer patients.

Eight subjects wearing five types of non-powered air-purifying respirators with different respiratory resistance and dead space were engaged in bicycle exercise test under medium(100W) and higher(155W) labor intensity,and the subjective well-being of subjects were recorded and analyzed.
