Mean age 62.2±11 years. Mean MEP value: 125.4 ±40 cm H20. Mean MIP value: 67.5 ±23 cm H20. Both MIP and MEP values were correlated positively with: 6MWT distance, FEV1 values (p<0.05), and negatively with: dyspnea, age (p<0.05). MEP value was correlated with weight (p<0.05). No relationship was found with RV, FRC values or with CAT, SGRQ, HADS questionnaires. Concerning the MIP, the lowest values were in stage II GOLD (60.1 cm H20) and in 41.4% of cases the values were < 60 cm H20 (inspiratory muscle fatigue threshold).Conclusions: In our group of COPD patients, respiratory muscle pressures were in relationship with age, weight, dyspnea, FEV1 values and 6MWT distance. Inspiratory muscle pressure was seriously affected in almost half of patients.
