What causes snoring in patients during assessment?

Snoring during assessment is primarily caused by the tongue blocking the airway. This phenomenon occurs when the muscles in the throat relax, particularly during sleep or in states of relaxation, allowing the tongue to fall backward and partially obstruct the airway. This obstruction leads to vibrations of the surrounding tissues, which is what produces the sound of snoring.

While other factors like fluid in the lungs, swelling in the throat, and gastroesophageal reflux can contribute to airway challenges or respiratory issues, they do not specifically result in snoring the way that an obstructed airway due to the tongue does. Recognizing this characteristic can help in the assessment of airway patency and the need for further intervention, especially in emergency situations.
