The Hering-Breuer reflex is initiated by lung expansion, which excites stretch receptors in the airways.
Berggren, P., Rigaut, J. P., Curstedt, T. & Robertson, B. Computerized image analysis of lung expansion patterns in surfactant treated immature newborn rabbits.
Our results suggest that the ventilator-driven lung expansion impaired the C18O2 blood uptake conductance, finally compensating for the beneficial effect of the increase in alveolar volume on DLC18O2 values.
In artificially ventilated animals we investigated the dependence of the pulmonary diffusing capacities of nitric oxide (NO) and doubly 18O-labeled carbon dioxide (DLNO, DLC18O2) on lung expansion with respect to ventilator-driven increases in intrapulmonary pressure.
Her regular chest X-ray revealed slight lung expansion but was otherwise almost normal.
Our findings indicate that the volumetric threshold for VILI coincides with the anatomical limits of lung expansion.
In hypoxemic critically ill patients, HFNC might improve oxygenation and patient's comfort by lung expansion and enhanced CO2 clearance.
We found that the threshold of VILI in the healthy lung is the region defining the inspiratory lung capacity, i.e., the anatomical limits of lung expansion.
On Bolivians (or Ecuatorians) playing at sea level... well, research states that they are at an advantage coming down from La Paz or Quito: the body usually has more red blood cells and greater lung expansion capability than needed.
There was lower sensitivity (69 78 %) in distinguishing right main-stem bronchus intubation from tracheal intubation, possibly due to transmitted movement of the left lung from right lung expansion [68].
The transition from the fetal to the neonatal circulation thus includes elimination of the placental circulation, lung expansion, and increase in lung blood flow so that the entire cardiac output can be accommodated, and closure of the foramen ovale, ductus arteriosus, and ductus venosus.
