Observation indices and evaluation criteria

This segment details the indicators and standards employed for evaluating the outcomes of the interventions, ensuring terminological consistency and academic rigor for journal publication.

Lung Function Assessment: To ascertain variations in lung function [Forced Expiratory Volume in 1 second (FEV1), Left Ventricular Ejection Fraction (LVEF)] pre- and post-intervention, patient evaluations were conducted using the pulmonary function testing instrument (SpiroUSB, SensorMedics), which facilitated precise measurement of key pulmonary indices.

Sleep Quality Analysis: The Pittsburgh Sleep Quality Index (PSQI) [13] was utilized to assess sleep quality differences between the two groups. The PSQI includes seven domains, including latency to sleep onset and overall sleep quality. Each domain is scored on a scale of 1-3 points, with the total score ranging from 7-21. Higher scores indicate poorer sleep quality among the subjects.

Inflammatory Factor Levels: The pre- and post-intervention serum levels of C-reactive protein (CRP) and procalcitonin (PCT) were compared between the two groups.

Quality of Life Evaluation: The 36-Item Short Form Survey (SF-36) Scale [14], including dimensions such as Physical Functioning (PF), Role Physical (RP), Bodily Pain (BP), General Health (GH), Vitality (VT), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH), was employed to assess the quality of life. The total score of Physical Component Summary (PCS) was calculated by PF+RP+BP+GH, and the total score of Mental Component Summary (MCS) was calculated by VT+SF+RE+MH. Higher scores in these dimensions signify a better quality of life.

Prognostic Factor Analysis: The prognosis of patients was evaluated based on the disappearance of clinical symptoms post-intervention and three consecutive negative nucleic acid tests, indicative of a positive prognosis. Other outcomes were categorized as negative prognoses [15].
