Objective To analyze the effect of special care on pulmonary function

blood gas levels and nursing satisfaction in patients with pulmonary infectious diseases. Methods Eighty-two patients with pulmonary infectious diseases treated in a hospital in Pingdingshan from March 2018 to July 2020 were selected for the study and divided into a study group（n=41） and a control group（n=41） using the random number table method. The patients in the control group were given conventional care

and the study group was given specialized care based on the care of the control group

and the patients in both groups were continuously cared for until they were discharged. The improvement of symptoms

blood gas levels [arterial partial pressure of oxygen（PaO

2

）

arterial partial pressure of carbon dioxide（Pa CO

2

） and arterial oxygen saturation（SaO

2

）]

pulmonary function [forced vital capacity（FVC）

forced expiratory volume in the first second（FEV

1

）/FVC]

length of stay and satisfaction with nursing care were compared between the 2 groups of patients before and after care. Results Before nursing care

there were no statistically significant differences between the cough frequency

cough volume and dyspnea degree scores of patients in the 2 groups（P

>

0.05）; after nursing care

the cough frequency

cough volume and dyspnea degree scores of patients in the 2 groups were lower than those before nursing care

and the study group was lower than the control group

with statistically significant differences（P

<

0.05）. Before care

there was no statistically significant difference between the PaO

2

Pa CO

2

and SaO

2

levels of the two groups（P

>

0.05）; after care

the PaO

2

and SaO

2

levels of the two groups were higher than before care

and the study group was higher than the control group

and the differences were statistically significant（P

<

0.05）; the Pa CO

2

level was lower than before care

and the study group was lower than the control group

and the differences were statistically significant（P

<

0.05）. Before nursing care

there was no statistically significant difference between the FVC and FEV

1

/FVC levels of the 2 groups; after nursing care

the FVC and FEV

1

/FVC levels of the 2 groups were higher than before nursing care

and the study group was higher than the control group

and the differences were statistically significant（P

<

0.05）. The length of stay of patients in the study group was shorter than that in the control group

and the difference was statistically significant（P

<

0.05）; the satisfaction score of nursing work was higher in the study group than that in the control group

and the differences were statistically significant（P

<

0.05）. Conclusion Specialized nursing care can effectively relieve patients with pulmonary infectious diseases by relieving clinical symptoms

improving blood gas levels and pulmonary function

shortening hospitalization time

and improving nursing job satisfaction

which is worthy of clinical promotion and use.
