Final answer:
In cervical auscultation, clinicians listen for respiratory sounds, preparatory sounds of saliva and mouth movements, and pharyngeal sounds before the swallow to evaluate swallow function.
Step-by-step explanation:
Cervical auscultation is an assessment technique used by clinicians to evaluate the sounds associated with swallowing. Before the swallow, it is important to listen for several key sounds to assess the swallow function. When using a stethoscope, one should pay attention to the following sounds before the swallowing event:
- Respiratory sounds: These include breath sounds before the initiation of the swallow. It is important to note the pattern and any abnormalities that might indicate difficulty with coordinating breathing and swallowing.
- Preparatory sounds: This refers to the sound of saliva accumulation or movements of the mouth and tongue as the food is chewed and prepared for swallowing.
- Pharyngeal sounds: Any sounds that might occur as the pharyngeal phase of swallowing is about to start can be indicative of the timing and coordination of the swallow.
Cervical auscultation can be an important part of a dysphagia assessment when conducted by trained professionals.
