Final answer:
The presence of sputum in the airways can be indicated by abnormal breath sounds, colored mucus samples, and chest radiographs revealing lung irregularities, confirmed by a physical examination and diagnostic tests.
Step-by-step explanation:
Indications of Sputum in Airways:
The presence of sputum in the airways can be indicated by abnormal sounds heard during a physical examination, the collection of colored mucus, and imaging results showing irregularities in the lungs. A microscopic examination of sputum can reveal organisms responsible for infections, such as pneumonia or tuberculosis (TB). Additionally, a chest radiograph may show shadows or opacities suggesting the presence of excess mucus or other abnormalities.
To confirm the presence of sputum, health professionals may use diagnostic tools like stethoscopes to identify crackling sounds or crepitation, and pulse oximeters to detect low blood oxygen levels. Additionally, a nebulizer or spirometry tests can assist in diagnosing restrictive lung diseases that involve mucus obstruction.
