What is the maximum suction pressure recommended for an adult?

The maximum suction pressure recommended for an adult is 120 mm Hg. This level helps effectively clear secretions from the airways without causing harm to the respiratory mucosa. Maintaining this pressure helps balance the need to remove obstructive mucus while minimizing the risk of trauma to the airway tissues.

Higher pressures, such as 150 mm Hg, could lead to increased irritation, damage to the delicate lung tissue, and potential complications such as bleeding. A suction pressure of 100 mm Hg may not be sufficient to adequately clear thicker secretions in some patients, while 80 mm Hg may be too low for effective suctioning. Therefore, 120 mm Hg is considered the optimal range to ensure safety and effectiveness in respiratory care for adults.
