Mechanical ventilators are safety-critical devices that help patients breathe, commonly found in hospital intensive care units (ICUs)-yet, the high costs and proprietary nature of commercial ventilators inhibit their use as an educational and research platform. We present a fully open ventilator device-The People's Ventilator: PVP1-with complete hardware and software documentation including detailed build instructions and a DIY cost of $1,700 USD. We validate PVP1 against both key performance criteria specified in the U.S. Food and Drug Administration's Emergency Use Authorization for Ventilators, and in a pediatric context against a state-of-the-art commercial ventilator. Notably, PVP1 performs well over a wide range of test conditions and performance stability is demonstrated for a minimum of 75,000 breath cycles over three days with an adult mechanical test lung. As an open project, PVP1 can enable future educational, academic, and clinical developments in the ventilator space.

As urbanization accelerates, the issue of pollutant discharge from building materials has become the focus of public attention. Conducted in a ventilated environmental chamber, the experiments investigated the emission characteristics of VOCs from dry and wet building materials, focusing on the influencing factors, such as temperature, relative humidity (RH), ventilation, and seasonality. The impact of influencing factors was quantified using a one-factor-at-a-time control method.

Background: Standardized spontaneous breathing trial (SBT) techniques for patients with heart failure (HF) are lacking.
Objectives: To compare the efficacy of low-level pressure-supported ventilation (PSV) and T-piece SBT techniques in patients with HF.
Methods: This single-center, prospective, open-label, randomized controlled study enrolled mechanically ventilated adults with stage B HF (Nov 2022-Apr 2024).

Multiple system atrophy (MSA) is a progressive, adult-onset neurodegenerative disorder involving autonomic failure, cerebellar ataxia, and parkinsonism. Patients often require invasive interventions, such as gastrostomy or tracheostomy, and sudden death is common. This study aimed to elucidate patterns of invasive treatment and identify risk factors for tracheostomy or sudden death within 5 years of onset.

Background: This study aims to develop an interpretable machine learning model using SHapley Additive exPlanations (SHAP) to predict favorable outcomes based on clinical, imaging, and angiographic data.
Methods: This study analyzed data from 184 patients with acute basilar artery occlusion (BAO) who underwent endovascular treatment (EVT) and completed a 90-day follow-up at Shanxi Provincial People's Hospital. A total of 68 medical variables were collected to develop predictive models using three machine learning algorithms: logistic regression (LR), support vector machine (SVM), and Light Gradient Boosting Machine (LightGBM).
