Should flow-restricted, oxygen-powered breathing devices (demand valves) be used to ventilate children? Why?
What will be an ideal response?
No. Flow-restricted, oxygen-powered breathing devices deliver high pressures and do not allow the operator to feel pulmonary compliance. Therefore, they are more likely to cause pneumothorax in children.
