Pulmonary stretch receptor activity during partial liquid ventilation in cats with healthy lungs [PDF]

, 2004
Aim: To study whether pulmonary stretch receptor (PSR) activity in mechanically ventilated young cats with healthy lungs during partial liquid ventilation (PLV) is different from that during gas ventilation (GV).

Natural ventilation for the prevention of airborne contagion. [PDF]

, 2007
BACKGROUND: Institutional transmission of airborne infections such as tuberculosis (TB) is an important public health problem, especially in resource-limited settings where protective measures such as negative-pressure isolation rooms are difficult to ...

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

Respirology 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]

Postgraduate 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]

, 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.

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

ERJ 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
