In addition to affecting the respiratory system, chronic obstructive pulmonary disease also decreases muscle mass. The respiratory muscles weaken, which impairs ventilation and exercise tolerance. According to recent studies, M-mode ultrasonography provides a dependable and user-friendly method for evaluating diaphragmatic mobility in patients with COPD.
Objective Evaluate diaphragmatic excursion by ultrasound in M-mode in patients with COPD and correlate with different clinical and ventilatory variables.
Methods We conducted a prospective, observational study from 2021 to 2024. A total of Sixty-one consecutive patients with spirometryconfirmed stable COPD were included after obtaining informed written consent. Demographic and clinical data, spirometric values, BMI, 6-minute walking test as well as blood gas and Measurement of and Excursion (EXdi) were collected for analysis. This is a prospective study conducted at Constantine Regional Military University Hospital
Results The mean diaphragmatic excursion, evaluated by ultrasound (EXdi), in our patients with COPD was 5.01 cm ± 1.48 cm, In our study a correlation between the EXdi and spirometric data (FVC; FEV1; FEV1/FVC) was objectified with (P < 0,001) the majority of our patients were classified grade 1 and grade 2 according to MMRC (Figur 4) the average of PaCO2 is 36,57 (mmHg), a negative correlation has been reported between L’EXdi and the dyspné MMRC (P < 0,001) The average BMI is 24.12 4.83 kg/m 2, with extreme values ranging from 14.6 to 36.9 kg/m 2, a positive correlation has been reported between L’EXdi and the BMI (P= 0,015) a positive rrelation has been reported between L’EXdi and the PaO2 (mmHg) (P =0,009),and a negative correlation has been reported between L’EXdi and the PaCO2 (mmHg) (P =0,022), The average distance travelled in this test was 470 129.37 m , our study has shown that the more EXdi increases, the distance patients travel increases (P =0,001)
Conclusion In patients with COPD, diaphragmatic mobility appears to be associated with airway obstruction and BMI,6- minute walking test as well as blood gas and perception of dyspnea
