The objective of this study is to determine the average value of various upper and lower respiratory tract parameters (PNIF, FEV1, FEV1/VC) as they relate to a patient's clinical diagnosis. All diagnoses were made during medical examination by a physician based on specific criteria. The study encompassed 288 ECAP participants (96 participants 9-10 years of age, 84  participants 16-17 years of age, and 108 participants 23-47 years of age) residing in the areas surrounding Zamość. Research methods employed included spirometry and the measurement of peak nasal inspiratory flow in L/min using a specially constructed mask. For analysis of the results, the participants were divided into three groups:

-        Patients diagnosed with seasonal rhinitis- mean values: PNIF: 90.23 L/min, FEV1: 99.27%, FEV1/VC: 101.95%

-        Patients diagnosed with perennial rhinitis- mean values: PNIF: 99.93 L/min, FEV1: 98.77%, FEV1/VC: 98.83%

-        Patients with diagnosed asthma including:

-        Light asthma- mean values: PNIF: 86.15 L/min, FEV1: 90.31%, FEV1/VC: 96.15%.

-        Moderate asthma- mean values: PNIF: 92.5 L/min, FEV1: 89%, FEV1/VC: 93.25%, 

-        Severe asthma- mean values: PNIF: 87.23 L/min, FEV1: 87.73%, FEV1/VC: 95.45%.

In conclusion, the lowest values for the selected upper and lower respiratory tract parameters were obtained from the group of patients diagnosed with bronchial asthma, especially severe asthma.
