Which of the following ranges identifies the amount of pressure within the endotracheal tube cuff that is believed to prevent both injury and aspiration?

Which of the following ranges identifies the amount of pressure within the endotracheal tube cuff that is believed to prevent both injury and aspiration?
a) 20-25 mm Hg water pressure.
Usually the pressure is maintained at less than 25 cm water pressure to prevent injury and at more than 20 cm water pressure to prevent aspiration.
b) 10-15 mm Hg water pressure.
A measure of 10–15 mm Hg water pressure would indicate that the cuff is underinflated.
c) 30-35 mm Hg water pressure.
A measure of 30–35 mm Hg water pressure would indicate that the cuff is overinflated.
d) 0-5 mm Hg water pressure
A measure of 0-5 mm Hg water pressure would indicate that the cuff is underinflated.
