How is wheezing characterized?

Low blood pressure
High fever
High pitched whistling sound
Toothache

The correct answer is: High pitched whistling sound

Wheezing is characterized by a high-pitched whistling sound often heard during breathing, particularly when exhaling. This sound occurs due to the narrowing or constriction of the airways, which can be the result of conditions such as asthma, bronchitis, or an allergic reaction. The high-pitched quality of wheezing distinguishes it from other respiratory sounds and indicates difficulties in airflow through the bronchial tubes. Recognizing this sound is crucial for EMTs as it can inform them about the patient's respiratory status and potential underlying issues that require urgent medical attention.
