The dose needed to develop BPD in murine models are frequently very high (FiO2 >0.8), which does not precisely correlate with the dose used usually in patients. WebThus, ventilation during anaesthesia should be done if possible with a moderate fraction of inspired oxygen (FIO2, e.g. 0.3-0.4). Alternatively, if the lungs are ventilated with a high inspiratory fraction of oxygen, the use of PEEP may be considered. dance can be defined as
