A wheeze (formally called "sibilant rhonchi" in medical terminology) is a continuous, coarse, whistling sound produced in the respiratory airways during breathing. For wheezes to occur, some part of the respiratory tree must be narrowed or obstructed, or airflow velocity within the respiratory tree must be heightened. Wheezing is commonly experienced by persons with a lung disease; the most common cause of recurrent wheezing is asthma attacks, though it can also be a symptom of lung cancer.
The differential diagnosis of wheezing is wide, and the reason for wheezing in a given patient is determined by considering the characteristics of the wheezes and the historical and clinical findings made by the examining physician.
Wheezes occupy different portions of the respiratory cycle depending on the site of airway obstruction and its nature. The fraction of the respiratory cycle during which a wheeze is produced roughly corresponds to the degree of airway obstruction.Bronchiolar disease usually causes wheezing that occurs in the expiratory phase of respiration. The presence of expiratory phase wheezing signifies that the patient's peak expiratory flow rate is less than 50% of normal. Wheezing heard in the inspiratory phase on the other hand is often a sign of a stiff stenosis, usually caused by tumors, foreign bodies or scarring. This is especially true if the wheeze is monotonal, occurs throughout the inspiratory phase (i.e. is "holoinspiratory"), and is heard more proximally, in the trachea. Inspiratory wheezing also occurs in hypersensitivity pneumonitis. Wheezes heard at the end of both expiratory and inspiratory phases usually signify the periodic opening of deflated alveoli, as occurs in some diseases that lead to collapse of parts of the lungs.
Off with your head
Dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Glitter on the wet streets
Silver over everything
The river's all wet
You're all cold
Dripping with alchemy
Shiver stop shivering
The glitter's all wet
You're all chrome
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
Oh, oh, oh, oh
Off, off with your head
Dance, dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Looking glass, take the past
Shut your eyes, you realize
Looking glass, take the past
Shut your eyes, you realize
Glitter on the wet streets
Silver over everything
The glitter's all wet
You're all chrome, you're all chrome
Oh, oh, oh
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
