In the prone position, computed tomography scan densities redistribute from dorsal to
ventral as the dorsal region tends to reexpand while the ventral zone tends to collapse …

Prone position (PP) has been used since the 1970s to treat severe hypoxemia in patients
with ARDS because of its effectiveness at improving gas exchange. Compared with the …

Background The COVID-19 pandemic is challenging advanced health systems, which are
dealing with an overwhelming number of patients in need of intensive care for respiratory …

Background Awake prone positioning (awake-PP) in non-intubated coronavirus disease
2019 (COVID-19) patients could avoid endotracheal intubation, reduce the use of critical …

Nunn's Applied Respiratory Physiology, Ninth Edition, is your concise, one-stop guide to all
aspects of respiratory physiology in health, disease, and in the many physiologically …

The gravitational gradient of intrapleural pressure is suggested to be less in prone posture
than supine. Thus the gravitational distribution of ventilation is expected to be more uniform …

Background One of the central physiological functions of the lungs is to transfer inhaled
gases from the alveoli to pulmonary capillary blood. However, current measures of alveolar …

Purpose Hyperpolarized 129Xe magnetic resonance imaging (MRI) using Dixon‐based
decomposition enables single‐breath imaging of 129Xe in the airspaces, interstitial barrier …

Acute pulmonary embolism causes redistribution of blood in the lung, which impairs
ventilation/perfusion matching and gas exchange and can elevate pulmonary arterial …

Purpose To evaluate lung water density at three different levels of lung inflation in normal
lungs using a fast gradient echo sequence developed for rapid imaging. Materials and …
