Vacuum suction pressure in adults is?

Appeared in: NORCET 1 - 2020

Explanation

120 mmHg is a safe and effective pressure for suctioning an adult's airway, as it falls within the standard recommended range.
The recommended vacuum suction pressure for an adult is between 100 and 150 mmHg.
This pressure level is sufficient to clear secretions effectively while minimizing the risk of complications like mucosal trauma, bleeding, or hypoxemia.

Option B: This pressure is too high for an adult. It exceeds the maximum recommended pressure of 150 mmHg and significantly increases the risk of causing mucosal damage, bleeding, and hypoxemia.
Option C: This pressure is too low to be effective for an adult. It would likely fail to clear thick or copious secretions from the airway.
Option D: This pressure is entirely inadequate for an adult airway and would be ineffective for clearing secretions.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Airway Management: Suction Pressure Settings as background academic context rather than a clinical decision trigger.
Applying the correct suction pressure is a critical nursing skill to balance effective secretion removal with patient safety.
Using excessive pressure can lead to serious iatrogenic complications, including hypoxia, atelectasis, mucosal trauma, and bleeding.
Using insufficient pressure can lead to ineffective secretion clearance, resulting in airway obstruction, poor oxygenation, and increased risk of infection.

How to Approach the Question

Identify the core of the question: it asks for a specific clinical parameter (vacuum suction pressure) for a specific patient population (adults).
This is a factual recall question. Access your knowledge of standard nursing procedures and safety guidelines.
Recall the standard suction pressure ranges for different age groups: Adults, Children, Infants, and Neonates.
The standard range for adults is 100-150 mmHg.
Evaluate each option against this range. 120 mmHg is the only option that falls within the correct range.
Eliminate the other options by identifying them as either too high (170 mmHg) or too low/appropriate for other age groups (80 mmHg for infants/neonates, 60 mmHg for neonates).
