Assessment of Ventilation and Perfusion in Patients with COVID-19 Discloses Unique Information of Pulmonary Function to a Clinician: Case Reports of V/P SPECT

open access: yesClinical Medicine Insights: Circulatory, Respiratory and Pulmonary Medicine, 2021
V/P SPECT from 4 consecutive patients with COVID-19 suggests that ventilation and perfusion images may be applied to diagnose or exclude pulmonary embolism, verify nonsegmental diversion of perfusion from the ventilated areas (dead space ventilation ...

High tidal volume ventilation is not deleterious in infant rats exposed to severe hemorrhage [PDF]

open access: yes, 2010
BACKGROUND: Both high tidal volume (VT) ventilation and hemorrhage induce acute lung injury in adult rodents. It is not known whether injurious ventilation augments lung injury in infant rats exposed to severe hemorrhage.

Noninvasive ventilation in stable hypercapnic COPD: what is the evidence?

open access: yesERJ Open Research, 2018
Long-term noninvasive ventilation (NIV) to treat chronic hypercapnic respiratory failure is still controversial in severe chronic obstructive pulmonary disease (COPD) patients. However, with the introduction of high-intensity NIV, important benefits from

Novel pulmonary perfusion imaging using chest digital dynamic radiography for pulmonary artery sarcoma

open access: yesRespirology Case Reports, 2021
Key message Chest digital dynamic radiography (DDR) is a novel method for evaluating pulmonary perfusion and ventilation. It could depict ventilation–perfusion mismatch in a pulmonary artery sarcoma with severe stenosis in the right pulmonary artery ...

From state-of-the-art ventilation to closed loop ventilation

open access: yes, 2022
Recent emphasis on energy load delivered during each ventilatory breath has opened a new insight to reduce harmful ventilatory induced lung injury, but no robust clinical evidence of patient benefit produced yet. Closed loop ventilation is a strategy to
