alveoli, trachea, bronchi of the pulmonary tract.
Secretion of the goblet cells (lining the respiratory tract)
Sputum
Sputum Normal Condition:

Macrophages with carbon deposits
Ducts cell
SPUTUM: Preservation
Refrigeration

Physical Characteristics of sputum
Quantity/Volume
Consistency
Reaction
Turbidity
Odor
Color
Volume of sputum
No specific volume
Small amount- not always normal
Dse. Associated:
a. early PTB
b. acute bronchitis
c. pneumonia
Over 100cc/24hrs
Dse. Associated:
pulmonary edema
Broncheictasis- characterized by bronchial dilatations/swelling of bronchi
Lung abscess - lesion of lungs
Over 500cc/ 24hrs
Dse. Associated:
Amoebic abscess - infection parasites
Over 1,000cc/ 24hrs
Dse. Associated:
severe broncheictasis
cavity TB - hole on lungs
Acute edema of lungs
Chronic bronchitis
characterized by bronchial dilatations/swelling of bronchi
Bronchiectasis
lesion on the lungs because of infection.
Lung abscess
Frothy sputum or serouf
Pulmonary edema
infection caused by parasite
Amoebic abscess
hole on lungs/ white spots on the lungs
Cavity TB
Consistency: sialic acid is responsible for sputum’s viscosity
Watery
Consistency: Blood-gelatinous sputum (Currant-Jelly) disease
Klebsiella pneumoniae infection
Pneumococcal pneumonia
Consistency: Cloudy, mucoid sputum disease
Chronic bronchitis
Consistency: Three layered appearance (stagnant, purulent sputum)
Bronchiectasis
Lung abscess
Consistency: vFollows asthma exacerbation
Stringy mucoid sputum/ frothy
Reaction of sputum
Slightly acidic
Reaction of pH
6.5-7.0
Turbidity: Frothy sputum or serous (air bubble, hemoglobin)
Pulmonary edema
Turbidity: mucoid disease
•Bronchiectasis
•TB with cavities
Turbidity: Foamy, clear materials
Saliva
Nasal secretion
Normal odor of sputum
Odorless
Abnormally odor: In pulmonary tuberculosis with cavities, bronchiectasis, bronchomoniliasis
Sweetish
Abnormally odor: Usually due to Fusobacteria & Spirochetes found in mouth, or anaerobic infections within the lung,
lung abscess and necrotizing bronchogenic carcinoma
Putrid or foul
Abnormally odor: In necrosis or malignant tumors and perforating emphysema
Cheesy odor
Abnormally odor: Rupture sunphrenic or liver abscess and in enteric gram negative products
Fecal odor
Color: When made of mucus only
Colorless/translucent/opaque
Color: When pus is present, seen in advance pulmonary tuberculosis,
chronic bronchitis, jaundice and lobar pneumonia
White or yellow
Color: When pus and epithelial cells are present
Gray
