The diaphragm is the main breathing muscle and contraction of the diaphragm is vital for
ventilation so any disease that interferes with diaphragmatic innervation, contractile muscle …

In addition to the diaphragm's role as the primary respiratory muscle, it also plays an under-
recognized role in cardiac function. It serves as a pump facilitating venous and lymph return …

Background Weaning failure is a crucial hindrance in critically ill patients. Rapid shallow
breathing index (RSBI), a well-known weaning index, has some limitations in predicting …

Ultrasound (US) of chest, even with inherent limitations of the US beam and air, has been
useful in many pediatric chest conditions. It has extended its role and is now widely used by …

Purpose We have focused on the two-dimensional (B-mode) and the time-motion (M-mode)
analysis of the zone of apposition to determine the reliability of diaphragm ultrasonography …

Respiratory muscle weakness frequently occurs in patients with neuromuscular disease.
Measuring respiratory function with standard pulmonary function tests provides information …

Despite nearly a half century of studies, it has not been fully understood how pulmonary
alveoli, the elementary gas exchange units in mammalian lungs, inflate and deflate during …

Background Previous studies have demonstrated that respiratory dysfunction has a potential
association with low back pain (LBP). Despite the role of the diaphragm for respiration and …

Background and Objectives In this study, we examined the consistency, rapidity, and
reproducibility of the ABCDE technique for diaphragm identification. Operators using this …

Background Weaning failure is common in mechanically ventilated patients, and if
ultrasound can predict weaning outcome remains controversial. The purpose of this study …
