Background: The ventilatory physiopathology of patients with interstitial lung disease (ILD) remains poorly understood. We aimed to personalize a mechanical simulator to model healthy and ILD profiles ventilation, and to evaluate the effect of spontaneous breathing on respiratory mechanics at rest and during exercise.
Methods: In a 2-compartment lung simulator (ASL 5000), we modeled 1 healthy and 3 ILD profiles, at rest and during exercise, based on physiological data from literature and patients.
Background: Oxygen uptake (V̇O2) and heart rate (HR) kinetics during a constant work-rate test (CWRT) are used to evaluate the response to exercise in healthy subjects as well as subjects with various pathologies.
Objectives: This study aimed to explore the feasibility of these measures and their responsiveness to a prehabilitation program in patients with non-small cell lung cancer (NSCLC).
Method: This study is preregistered (NCT04041297) ancillary analysis of a subgroup of individuals with NSCLC included in the Preo-Dens study (NCT03936764).
Question: In people with non-small cell lung cancer, what is the effect of condensing 15 prehabilitation sessions into a 3-week regimen compared with a 5-week regimen?
Design: Randomised controlled trial with concealed allocation, intention-to-treat analysis and blinded assessment of the primary outcome.
Participants: People with diagnosed or suspected non-small cell lung cancer and moderate-to-high risk of postoperative complications.
Intervention: Fifteen supervised prehabilitation sessions delivered with either a dense regimen of five sessions/week for 3 weeks (experimental group) or a non-dense regimen of three sessions/week for 5 weeks (control group).
Background: Pulmonary rehabilitation (PR) (primarily composed of an exercise training program (ET) and educational workshops) is an effective intervention for patients with chronic obstructive pulmonary disease. Although factors which influence participation in the full PR program have been reported, specific data on the educational component of PR have not been published. We aimed to identify factors which predict refusal to participate in the educational component of PR.

Its non-specific clinical manifestations frequently lead to misdiagnosis and delay in its treatment. The treatment of VCD is not pharmacological but rehabilitative and remains poorly appreciated.

Methods: Data collected routinely from people referred for cardiopulmonary exercise testing (CPET) following hospitalization for COVID-19 were retrospectively analyzed. Persistent dyspnea was assessed using the modified Medical Research Council dyspnea scale.
Purpose: A decision tree based on a clinicophysiological score (severe high-altitude illness (SHAI) score) has been developed to detect subjects susceptible to SHAI. We aimed to validate this decision tree, to rationalize the prescription of acetazolamide (ACZ), and to specify the rule for a progressive acclimatization.
Methods: Data were obtained from 641 subjects in 15 European medical centers before and during a sojourn at high altitude.
Background: Maximal oxygen consumption (V O) is the most frequently used variable to determine postoperative risk in patients with non-small cell lung cancer (NSCLC), however patients frequently cannot provide the necessary maximum effort to ensure the validity of the V O measurements. The aim of this observational study was to assess exercise-limiting factors and the rate of achievement of the currently recommended maximality criteria in patients with NSCLC who had been routinely referred for cardiopulmonary exercise testing (CPET) to assess their postoperative risk.
Methods: Patient data, including peak exercise variables and markers used to designate the exercise test as maximal, were retrospectively analysed from 203 preoperative CPET assessments that were performed at Rouen University Hospital from January 2014 until July 2019.
Background: Peak oxygen uptake ( ) measured by a cardiopulmonary exercise test (CPX) is the gold-standard for predicting surgical risk in patients with non-small cell lung cancer (NSCLC). The 3-minute chair rise test (3CRT) is a simple test requiring minimal resources. This study aimed to determine the ability of 3CRT to predict in patients with NSCLC.

We assessed whether these parameters affect endurance exercise capacity in severe COPD patients. In total, 21 patients with severe COPD not eligible to home NIV performed three constant workload tests.

To cope with these difficulties, field tests are often used to prescribe endurance training. As field tests are related to muscle strength, they could also be used to prescribe strength training and increase the access to pulmonary rehabilitation in rural area.

Pulmonary rehabilitation before surgery (prehabilitation) improves postoperative risk factors such as forced expiratory volume in 1 second and peak oxygen consumption (VO). Ventilatory inefficiency assessed according to the linear regression of the ratio between the increase in minute ventilation and the expired carbon dioxide flow during CPET (VE/VCO slope) >35, is a high-risk factor for postoperative complications.

A 62-year-old woman, with regular physical activity and no history of respiratory disease or smoking, was hospitalized for moderate ARDS with bilateral pneumonitis. Fourteen days later, she was discharged from the intensive care unit and received respiratory physical therapy.

Therefore, CPET is often incorporated in the preoperative assessment of cancer patients. This clinical case report presents the preoperative assessment of a patient before thoracic surgery, in whom an important decrease of aerobic capacity was noted, possibly because of muscular toxicity linked to chemotherapy.

Do they consider remote transmission of oximetry data to be satisfactory? Are the transmitted data valid compared with locally stored data?
Design: Multicentre, prospective, observational study.
Participants: One hundred and five adults with chronic respiratory disease who were referred to pulmonary rehabilitation.
Intervention: At an initial session, participants were taught to record and transmit their oximetry data to a remote server.
Background: Thoracic surgery is currently the optimal treatment for non-small cell lung cancer (NSCLC). However, it may be responsible for numerous postoperative complications and is often used in patients with multi co morbidities. In recent years, the optimization of a patient's physical capacity before surgery has been the subject of several studies.

Design: A randomized, single-blind, placebo-controlled crossover trial.
Setting: Pulmonary rehabilitation department.
Objective: To assess the additional effect of a home-based neuromuscular electrical stimulation (NMES) program as an add-on to pulmonary rehabilitation (PR), on functional capacity in subjects with chronic obstructive pulmonary disease (COPD).
Design: Single-blind, multicenter randomized trial.
Setting: Three PR centers.
Purpose: Diaphragm paresis (DP) is characterized by abnormalities of respiratory muscle function. However, the impact of DP on exercise capacity is not well known. This study was performed to assess exercise tolerance in patients with DP and to determine whether inspiratory muscle function was related to exercise capacity, ventilatory pattern and cardiovascular function during exercise.
