Objective:
To assess the level of tolerance for exercise in patients with chronic obstructive
pulmonary disease (COPD) with low div weight.
Research Materials and Methods.
In 21 patients with a COPD3 of 20 to 25 with a COPD of less
than 17 and a COPD of 10 with a mass gain of less than 17, gas exchange was observed at rest and
during physical activity. The study was conducted. Breathing with automatic analysis of indicators
performed using EOS-Sprint analyzer apparatus (Germany): work done (W, watts), oxygen
consumption indicator (due to VO2ml / min%) carbon dioxide emissions (VCO2 l / min , due to%),
ventilation reserve (BR,%), oxygen pulse (O2R, ml / min / HR,% condition), respiration coefficient
(RQ, rel. units), ratio of dead space to tidal volume (Vd / W), minute ventilation of the lungs at rest
(Ve, l / min), maximum minute ventilation during exercise (Vemax, l / min), ventilation oxygen
equivalent (VeO2), ventilation carbon dioxide equivalent (VeCo2).
Results.
In patients with COPD less than 17 with MRC, there was a significant decrease in the rate
of work performed in the ergospirometry comparison group (p <0.01) (95.2 + -3.1 and 120.9 + -3.1
watts), VO2 50.6 + -2.2 vs. 67.2 + -2.5%) VCO2 (61.1 + -2.8% vs. 49.9 + -2.0) and ventilation
reserves ( 35.2 + -0.6% compared to 25.2 + -0.1). There was no statistically significant difference
in maximum ventilation. The RQ at maximum load in low-weight patients was lower than the mean
unit (0.99 + -0.01) and was explained by the fact that the majority of patients in this group did not
reach the anaerobic limit. In low-weight COPD patients, the parameters of the oxygen pulse and
the percentage of maximum allowable heart rate were characterized by a decrease in the O2R index,
but it was not accompanied by a significantly higher heart rate than the increase in load. . For
patients with low-grade COPD, Vd / W (0.32 + -0.01) was higher than (0.25 + -0.02) with lower
respiratory barriers and higher respiratory stereotype.
Conclusion.
Violation of the internal condition of the patient, which leads not only to a decrease
in ventilation reserve, but also to a change in the effect of ventilation on the load, which is associated
with changes in respiratory properties at maximum load. characterized by a significant increase in
respiration rate without a significant increase in tidal volume and without a gap at high ventilation
levels.
