Le Mans general hospital has created an advanced practice nurse position in memory clinics in geriatrics. The activity began in September 2019. During the first year, 189 consultations with the nurse were carried out, despite the difficult health context.

The amount of bronchodilator that deposits at its site of action depends on the amount of drug, inhaled mass, deposited mass, and particle size distribution. Mechanical ventilation challenges both inhaled mass and lung deposition by specific features, such as a ventilatory circuit, an endotracheal tube, and ventilator settings.

- The study aimed to investigate the viscoelastic properties of piglet lungs and thoracic walls, using a controlled experimental approach with six 30 kg piglets undergoing tracheotomy and mechanical ventilation.
- Acute lung injury was induced to measure changes in lung and thoracic wall tissue resistance, using a rapid airway occlusion technique to assess how different pressures affected viscoelastic properties.
- Results showed a significant increase in lung resistance and time constant during acute lung injury, indicating altered mechanical properties, with varying effects observed under zero end-expiratory pressure and positive end-expiratory pressure conditions.
Introduction: Inspiratory Capacity (IC), which reflects dynamic pulmonary hyperinflation, correlates with outcome in moderate exacerbation of COPD. Whether this is also true in COPD with acute respiratory failure (ARF) has not been studied.
Methods: A prospective multicenter assessment of IC measurement feasibility, reliability, time-course and relationship to outcome in COPD with ARF was conducted.
Objective: To determine whether gas exchange response to a first prone position session can predict patient outcome in hypoxemic acute respiratory failure.
Methods: Data from a previous multicenter randomized controlled trial were retrospectively analyzed for relationship between PaO(2)/FIO(2) ratio and PaCO(2) changes during the first 8-h prone position session to day 28 mortality rate; 370 prone position sessions were analyzed. Arterial blood gas was measured in supine position before proning and in prone position at the end of the session.
