Ventilatory efficiency parameters in patients with normal exercise capacity
dyspnea
As we observed that a majority of patients with normal exercise capacity showed elevated mean ventilatory equivalents for COIt was worth noting that at AT, 18 of those 48 patients (37.5%) had a V′E/V′COEvolution of ventilatory efficiency parameters from rest to peak in patients with normal exercise capacity (n = 48). Univariate analysis revealed that dead space at peak (VD/Vt) was associated with parameters related to pulmonary exchange capacity at rest (pulmonary diffusing capacity) and during exercise (V′E/V′COResults of univariate analysis to identify factors associated with peak VD/Vt in patients with normal exercise capacity (n = 48)BMI, Body mass index; ICU, Intensive care unit; CRP, C-reactive protein; WBC, White blood cell; FEV1, Forced expiratory volume at 1st second; FVC, Forced vital capacity; TLC, Total lung capacity; DBold represents Interestingly, patients with dyspnea (n = 23) had a significantly higher mean peak dead space (0.32 ± 0.07 vs 0.28 ± 0.06;
