Mechanics of ventilation inception

WebAlthough patients may be ventilated for many days, typical rodent models use supraphysiological degrees of lung stretch over 3–4 hours. This is partly a reflection of the difference in respiratory mechanics among species, but is also a consequence of the practical difficulties of keeping small animals physiologically stable beyond short periods.
