Ch. 11 - Respiratory System V
Common Signs and Symptoms
●Sneeze
○Expelling air forcibly through the nose and mouth by spasmodic
contraction of muscles of expiration due to irritation of nasal mucosa
●Stridor
○Harsh sound
■Usually noted during inhalation
○High pitched and resembling the blowing of wind
■Due to the obstruction of air passages
○Can be heard without the use of a stethoscope
●Tachypnea
○Abnormal rapidity of breathing
●Wheeze
○Whistling sound or sighing sound resulting from the narrowing of the
lumen of a respiratory passageway
○Usually noted during exhalation
○Often can be heard without use of a stethoscope
Pathological Conditions of the Upper Respiratory System
●Coryza
○inflammation of the respiratory mucous membranes
○Aka the common cold
■“Common cold” usually refers to symptoms of an upper respiratory
tract infection
●Croup
○Childhood disease characterized by a barking cough, hoarseness,
tachypnea, inspiratory stridor, and laryngeal spasm
○Obstruction of the larynx may be due to an allergen, foreign object,
infection, or tumor
●Diphtheria
○Serious infectious disease affecting the nose, pharynx, or larynx, usually
resulting in sore throat, dysphonia, and fever
○Caused by bacterium Corynebacterium diphtheria
■Forms a white coating over affected airways as it multiplies
■Rare in the US due to availability of DPT vaccination
●Laryngitis

Due to the obstruction of air passages. Can be heard without the use of a stethoscope. Whistling sound or sighing sound resulting from the narrowing of the lumen of a respiratory passageway. Often can be heard without use of a stethoscope. Common cold usually refers to symptoms of an upper respiratory tract infection. Childhood disease characterized by a barking cough, hoarseness, tachypnea, inspiratory stridor, and laryngeal spasm. Obstruction of the larynx may be due to an allergen, foreign object, infection, or tumor. Serious infectious disease affecting the nose, pharynx, or larynx, usually resulting in sore throat, dysphonia, and fever. Forms a white coating over affected airways as it multiplies. Rare in the us due to availability of dpt vaccination. Resulting in hoarseness, cough, and difficulty swallowing.
