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 ...

Pulmonary circulation and ventilation [PDF]

open access: yesPostgraduate Medical Journal, 1974
Summary The pulmonary circuit receives the whole of the cardiac output, and the flow through it is governed by events in the systemic circulation. Its function is gaseous exchange, and the low resistance and high capacitance of the circuit is subservient to this function.

Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography [PDF]

open access: yes, 2012
Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects.

Perioperative lung-protective ventilation strategy reduces postoperative pulmonary complications in patients undergoing thoracic and major abdominal surgery [PDF]

open access: yesKorean Journal of Anesthesiology, 2016
The occurrence of postoperative pulmonary complications is strongly associated with increased hospital mortality and prolonged postoperative hospital stays.

Predictive significance of the six-minute walk distance for long-term survival in chronic hypercapnic respiratory failure [PDF]

open access: yes, 2007
Background: The 6-min walk distance ( 6-MWD) is a global marker of functional capacity and prognosis in chronic obstructive pulmonary disease ( COPD), but less explored in other chronic respiratory diseases.

Management and prevention of chronic obstructive pulmonary disease exacerbations: a state of the art review [PDF]

open access: yes, 2009
Exacerbations of chronic obstructive pulmonary disease (COPD) are important events in the natural history of this prevalent and devastating condition. This review provides a concise, state of the art summary on prevention and management of exacerbations.

Atypical bilateral ventilation/perfusion mismatches in an asymptomatic patient suffering from metastatic thyroid cancer

open access: yesEuropean Journal of Hybrid Imaging, 2021
Background Pulmonary embolism is indicated by ventilation/perfusion (V/P) mismatches in ventilation/perfusion scintigraphy. However, other pathologies may also evoke segmental or lobar mismatches. Thus, diagnosis can be difficult in asymptomatic patients

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation [PDF]

open access: yes, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...
