A neonate delivered at 32 weeks, is put on a ventilator, and the X-ray shows "white out lung" with an arterial blood gas (ABG) revealing a PaO2 of 75 mmHg. The ventilator settings are an FiO2 of 70% and a rate of 50 breaths per minute. The next step to be taken should be?
AIncrease rate to 60 per minute
BContinue ventilation with the same settings
CWeaning ventilator
DIncrease FiO2 to 80
Which of the following parameters is most critical for maintaining optimal oxygenation?
AFiO2
BRespiratory rate
CPEEP
DTidal volume
Which of the following statements accurately describes the benefits of prone positioning in ventilation for a polytrauma patient with ARDS?
ACan improve oxygenation when used for 6-8 hours
BRecommended for patients with low PaO2/FiO2 ratio
CGenerally enhances oxygenation but not guaranteed for all patients
DCurrent evidence shows some improvement in outcomes with its use
