Observational Study
Airway and transpulmonary driving pressures and mechanical powers selected by INTELLiVENT-ASV in passive, mechanically ventilated ICU patients.
Driving pressure (ΔP) and mechanical power (MP) are predictors of the risk of ventilation- induced lung injuries (VILI) in mechanically ventilated patients. INTELLiVENT-ASV® is a closed-loop ventilation mode that automatically adjusts respiratory rate and tidal volume, according to the patient's respiratory mechanics. ⋯ In this short term observation study, INTELLiVENT-ASV selected ΔP and MP considered in safe ranges for lung protection. In a subgroup of ARDS patients, the combination of a recruitment strategy and INTELLiVENT-ASV resulted in an apparently safe ΔPL and MPL.

Randomized Controlled Trial
A randomized controlled trial on inspiratory muscle training in pulmonary hypertension: Effects on respiratory functions, functional exercise capacity, physical activity, and quality of life.
Impaired respiratory muscle function may be one of the causes of increased dyspnea, reduced exercise capacity, and physical activity (PA), and poor quality of life in pulmonary hypertension (PH). ⋯ The results of the study demonstrated that TIMT could increase MIP and did not improve other parameters of respiratory functions, functional exercise capacity, PA, and QoL in patients with PH.
