Vacuum suction pressure in adults is?

Appeared in: NORCET 1 - 2020

Explanation

The correct option, 120 mmHg, falls squarely within the recommended vacuum suction pressure range for adults, which is 100 to 150 mmHg.
This pressure level is considered optimal for effectively clearing airway secretions while minimizing the risk of iatrogenic complications.
Using a pressure within this range ensures a balance between therapeutic effectiveness and patient safety.

Option B: A pressure of 170 mmHg exceeds the maximum recommended limit of 150 mmHg for adults.
Option C: A pressure of 80 mmHg is too low to effectively clear secretions in an adult. It is at the lower end of the range for infants and the upper end for neonates.
Option D: A pressure of 60 mmHg is significantly below the required pressure for adults and would be ineffective.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Airway management and suctioning pressures as background academic context rather than a clinical decision trigger.
Proper suction pressure selection is a critical patient safety measure. Incorrect pressure can lead to ineffective secretion removal (if too low) or significant airway trauma and hypoxemia (if too high).
Nurses must always verify the suction setting before the procedure and adjust it based on the patient's age and clinical condition.
What if the patient has very thick, tenacious secretions? The nurse should first ensure adequate patient hydration and consider using a larger-sized suction catheter (within appropriate limits), but should not exceed the maximum recommended pressure of 150 mmHg. Collaborating with respiratory therapy for mucolytic agents may also be necessary.

How to Approach the Question

Identify the core question: The question asks for the standard vacuum suction pressure for an adult.
Recognize this as a factual recall question that requires knowledge of standard clinical parameters.
Recall the recommended suction pressure range for adults (100-150 mmHg).
Evaluate the given options against this range.
Select the option (120 mmHg) that falls within the correct range.
Mentally discard the other options by identifying them as too high (170 mmHg) or appropriate for other age groups (80 mmHg for infants, 60 mmHg for neonates).
