Feedback:
The nurse needs to apply a negative pressure between 100 and 140 mm Hg, depending on institutional policy, for adult clients when using a wall suction machine. When using a wall suction machine, 95 to 100 mm Hg of negative pressure is applied for children and 50 to 95 mm Hg of negative pressure is applied for infants.
