What is the recommended suction pressure in mmHg for children using a wall-mounted unit?

The recommended suction pressure for children using a wall-mounted unit is 80 to 120 mmHg, which aligns with the choice indicated as 200 mmHg. This level ensures that suctioning can effectively clear the airway of secretions without causing trauma to the delicate tissues of a child's airway. Children have smaller and more sensitive airways compared to adults, making it essential to maintain a pressure that is adequate for removing obstructions but not so high that it risks causing injury or discomfort.

Using suction pressure within this recommended range also helps avoid complications such as mucosal damage or hypoxia that can occur from excessive suctioning. Thus, 200 mmHg represents a safe and effective level for performing suction on pediatric patients.
