Comparison of Ultrasound Measurements for Diaphragmatic Mobility, Diaphragmatic Thickness, and Diaphragm Thickening Fraction with Each Other and with Lung Function in Patients with Chronic Obstructive Pulmonary Disease.

Purpose: To compare ultrasound measurements of diaphragmatic mobility, diaphragm thickness, and diaphragm thickening fraction with one another and also with lung function parameters in patients with chronic obstructive pulmonary disease (COPD).

Patients And Methods: We conducted a prospective, observational study from 2015 to 2018. A total of 140 patients were randomly selected for this study.

Hypercapnia at Hospital Admission as a Predictor of Mortality.

Introduction: Hypercapnia is an indicator of ventilatory exhaustion. There is some disagreement regarding whether hypercapnia is also a predictor of mortality. In this prospective study, we aimed to investigate whether hypercapnia can predict in-hospital and 1-year mortality rates in patients with dyspnea or pulmonary diseases.

Endoscopic Lung Volume Reduction Results in Improvement of Diaphragm Mobility as Measured by Sonography.

Background: Hyperinflation in patients with pulmonary emphysema is an important cause of reduced diaphragm mobility. We investigated whether endoscopic lung volume reduction (ELVR) could improve diaphragm mobility.

Methods: Diaphragm mobility data obtained by sonography from 44 patients were compared before and 3-6 months after ELVR therapy with a Spiration™ valve system.
