Final answer:
Typical suction regulation pressure when applying medical suction can range up to 100-150 mm Hg, and should be adjusted to prevent tissue damage.
Step-by-step explanation:
The suction regulation pressure when applying suction in a medical context typically varies depending on the specific need and the patient's condition. However, common suction pressures for adults can range up to 100-150 mm Hg. It's crucial to adjust the suction pressure to the appropriate level to prevent tissue damage. When considering standard atmospheric pressure at sea level, which has a standard pressure of 760 mm Hg, the percentage used should not exceed this range without specific medical justification.
