Final answer:
Two groups that require simple pulmonary function testing are individuals with respiratory symptoms and individuals at risk for respiratory diseases.
Step-by-step explanation:
Two groups that require simple pulmonary function testing are individuals with respiratory symptoms and individuals at risk for respiratory diseases.
Respiratory symptoms can include shortness of breath, wheezing, coughing, and chest tightness. Examples of individuals with respiratory symptoms who would benefit from simple pulmonary function testing include those with asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
Individuals at risk for respiratory diseases can include smokers, individuals with a family history of respiratory diseases, and individuals exposed to occupational hazards such as chemicals or dust. Simple pulmonary function testing can help detect early signs of respiratory diseases in these individuals.
