Question

Vaccum suction pressure in adult is?
1. 120 mmHg
2. 170 mmHg
3. 80 mmHg
4. 60 mmHg

Answer 1

Correct Answer - Option 1 : 120 mmHg

Concept:

• Suctioning is the method of removing oral and respiratory secretions from the airway and keeping it clear.
• The vacuum suction system utilizes the principle of negative pressure to use a medical vacuum pump to evacuate the conveying pipe to produce the negative pressure and deliver it to the patient's bedside.

\Explanation:

• Vacuum suction pressure in adults is 120mmHg.
• The lowest vacuum pressure is recommended to reduce the risk of hypoxia and tracheal mucosa injury.
• However, the pressure has to be strong enough to remove the secretion. Usually, it's between 80 to 120 mmHg.
