Early changes in diaphragmatic function evaluated using ultrasound in cardiac surgery patients: a cohort study. [PDF]
, 2020 Little is known about the evolution of diaphragmatic function in the early post-cardiac surgery period. The main purpose of this work is to describe its evolution using ultrasound measurements of muscular excursion and thickening fraction (TF).

Novel Device for Measuring Lung Function using Oscillometry [PDF]
, 2020 The forced oscillation technique (FOT) is a non-invasive means of measuring lung mechanics. Broad-band oscillations in flow are delivered to the lungs while the resultant pressure oscillations are recorded.

Exploring Respiratory Motion Tracking Through Electrical Impedance Tomography [PDF]
IEEE Transactions on Instrumentation and Measurement, 2021 Motion tracking is an effective approach for the management of respiratory motion during the medical imaging process, which has always been a major concern in diagnostic imaging, interventional, and noninvasive therapy. However, the low imaging speed of traditional medical imaging techniques limits the practical application of real-time motion tracking.

Oscillatory respiratory impedance and lung tissue compliance
Respiratory Medicine, 1994 The respiratory impedance was measured by means of the forced oscillation technique (Landser et al.) and the lung tissue compliance was measured with an oesophageal balloon in 30 patients with a wide range of values of lung tissue compliance. According to the model of respiratory impedance of Nagels et al.

Issues Determining Direct Airways Hyperresponsiveness in Mice
Frontiers in Physiology, 2012 Airways hyperresponsiveness (AHR) is frequently a primary outcome in mouse models of asthma. There are, however, a number of variables that may affect the outcome of such measurements and the interpretation of the results.
