Comparative study on the effect of different high-frequency chest wall oscillation and back patting modes on sputum excretion in patients with severe pneumonia.

Background: The effect of different backslapping parameters on sputum discharge in SP patients is unclear.

Objective: To investigate the effects of different back-patting modes on sputum clearance from the lungs of SP patients. To provide a theoretical basis for future clinical care and development of critical care robots.

Methods: The patients with severe pneumonia in ICU of Guangyuan tertiary hospital were selected as the study object, and according to the specific conditions of the patients, different back-patting methods were selected and given different back-patting intensity, back-patting frequency, back-patting times, back-patting times, back-patting times, and back-patting times, respectively, to compare and analyse the effects of the different back-patting methods on the patient's expectoration effect, blood oxygen concentration, and lung signs.

Results: Finally, 143 patients with severe pneumonia were included. The volume of sputum expectoration, sputum viscosity, and blood oxygen saturation were significantly higher with different back patting patterns ( < 0.05), and the effective rate of treatment of pulmonary signs was significantly higher ( < 0.05).

Conclusion: Specific high-frequency chest wall shock back-patterning can effectively improve sputum expectoration in SP patients, helping to restore lung function and reduce hospital stay.
