Low resting inspiratory capacity (IC) and low maximal inspiratory pressure (MIP) have previously been linked to exertional dyspnea, exercise limitation, and poor survival in chronic obstructive pulmon...
Dry powder inhalers (DPIs) rely on both internal resistance and patients' inspiratory capacity for effective operation. Optimal inspiratory technique is crucial for DPI users. This study assessed the ...
The accuracy and repeatability of peak inspiratory flow (PIF) and forced inspiratory vital capacity (FIVC) against various internal resistances of the two devices were assessed using standard waveform...
PF810® showed great accuracy and repeatability in measuring PIF, except for square waveforms at the lowest flow rate (20 L/min). In-Check DIAL® exhibited poor accuracy against high resistance levels. ...
In-Check DIAL® exhibited poor accuracy and larger measurement errors than PF810® when detecting PIFs against higher internal resistances. However, its good performance against lower internal resistanc...
In patients with chronic obstructive pulmonary disease (COPD), static and dynamic hyperinflation, together with expiratory flow limitation and gas exchange abnormalities, is one of the major causes of...
Despite their pivotal role in COPD, IC and static volumes have rarely been considered as primary outcomes in randomized clinical trials assessing the efficacy of bronchodilators. Available studies on ...
This narrative review discusses the pathophysiological and clinical importance of measuring IC in patients with COPD and how IC can be modified by maximizing bronchodilation combining long-acting musc...
Dynamic hyperinflation (DH) is a major contributor to exercise intolerance in patients with obstructive lung diseases. However, it has not been investigated in children with bronchiectasis (BE). We ai...
Forty children with BE (mean forced expiratory volume in 1 s [FEV...
Twenty patients (50%) developed DH, and four patients (10%) were ventilatory limited (BR < %30) during 6MWT. There was a 176 [100-590] ml decrease in IC after exertion in patients with DH. DH did not ...
Although DH is common in children with BE, the severity of DH is rather low and may not seem to affect functional exercise capacity. However, peripheral muscle strength was a major contributor to func...
Current measures of tidal volume/forced vital capacity (VT/FVC) and VT/inspiratory capacity (VT/IC) at peak exercise cannot differentiate restrictive from obstructive ventilation patterns. This study ...
267 subjects were screened: 23 ILD, 126 COPD, and 33 healthy individuals were enrolled. Lung function tests and cardiopulmonary exercise tests with repeated IC maneuver were conducted and compared at ...
During exercise, ILD patients demonstrated normal end-expiratory lung volume/TLC (EELV/TLC) ratios, but elevated end-inspiratory lung volume/TLC (EILV/TLC) ratios, except for peak exercise. COPD patie...
Exercise-induced DH was absent in ILD patients but observed in COPD patients. Excessive lung expansion occurred in all patients during exercise, except for limited expansion in ILD at peak exercise pr...
Cervical spinal cord injury (CSI) often leads to impaired respiratory function, affecting the overall well-being of patients. This study aimed to investigate the influence of rib cage motion on inspir...
We conducted a study with 11 CSI patients, utilising respiratory inductance plethysmography (RIP). We measured ventilatory volume by spirometry concurrently with RIP. Participants were instructed to p...
The mean IC was 1.828 ± 0.459 L, with the mean V...
This study highlights the importance of rib cage motion in assessing inspiratory capacity in patients with CSI....
Exercise limitation is frequently described among asthmatic patients and could be related to different mechanisms of the pulmonary, cardiovascular and muscular systems. Despite this, cardiopulmonary e...
A monocentric observational study was conducted at Hanover Medical School, Germany, from April 2018 to June 2019. Patients affected by severe asthma treated with either mepolizumab or benralizumab wer...
14 patients were enrolled: 10 (71.4%) females, median age 52 years (IQR 47-61). Seven patients were treated with benralizumab, seven with mepolizumab. Oxygen uptake (...
CPET could show hints of alveolar recruitment and ventilatory efficiency in severe asthma patients treated with antibody therapy....
Low values of heart rate deceleration capacity (DC) and heart rate asymmetry (HRA) are associated with cardiovascular risks. Slow respiration has been proven to enhance the magnitudes of these indexes...
We evaluated 14 seated healthy young adults who randomly controlled their breathing to nine combinations of T...
The magnitude of DC increased when T...
We suggest that a T...
This study aimed to determine the effects of work-matched moderate-intensity and high-intensity inspiratory muscle warm-up (IMW) on inspiratory muscle strength and accessory inspiratory muscle activit...
Long-acting bronchodilators (LABD), in general, reduce respiratory symptoms, improve exercise endurance time and pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Howev...
This is a secondary analysis of the TORRACTO study: a multicenter, multinational, randomized, double-blind, placebo-controlled, parallel-group trial to evaluate the effects of T/O (2.5/5 and 5/5 μg) c...
Six clusters with distinct response profiles were generated at week 12 in COPD patients receiving T/O (n = 268). Patients in cluster 1 improved significantly on all outcomes, whilst cluster 5 showed s...
Individual responses on endurance time and pulmonary function after 12 weeks of T/O are heterogeneous. This study identified clusters in COPD patients with markedly different multidimensional response...
