Demystifying Volume Status

Summary Accurate evaluation of patient volume status is crucial yet challenging, impacting critical decisions on fluid management and vasoactive therapies. Traditional clinical methods often lack precision due to complexities in fluid distribution and homeostasis. This review provides a structured physiologic framework leveraging point-of-care ultrasound (POCUS) to assess volume status comprehensively. It emphasizes integrating central venous […]

Central venous pressure: current uses and prospects for an old parameter

Summary The article revisits the clinical relevance of central venous pressure (CVP), a traditional yet often underutilized hemodynamic parameter, given its historical inability to predict fluid responsiveness. It emphasizes that CVP still holds considerable diagnostic and management utility beyond fluid responsiveness, particularly as an indicator of venous return dynamics, organ perfusion, and right ventricular filling

Preoxygenation strategies for endotracheal intubation in resource-limited settings: reframing the basics

Summary This editorial reviews evidence-based strategies for preoxygenation during endotracheal intubation (ETI) specifically tailored to resource-limited settings (LRS). The authors underscore the challenges faced in achieving optimal preoxygenation where advanced devices are unavailable. They propose practical, low-cost alternatives and highlight recent evidence supporting the effectiveness of methods such as high-flow nasal cannula (HFNC), non-invasive positive

Fluid resuscitation management in patients with sepsis and septic shock: a network meta-analysis

Summary This network meta-analysis of 28 randomized controlled trials (8,770 patients) compares fluid resuscitation strategies in sepsis/septic shock. Balanced crystalloids (BC) demonstrated significant advantages, reducing 90-day mortality compared to saline (RR 0.89) and low-molecular-weight hydroxyethyl starch (L-HES; RR 0.84). Hyperoncotic albumin showed promise for renal protection but BC ranked highest overall, with superior outcomes for

Measurement and interpretation of central venous pressure: a narrative review

Summary This narrative review explores the historical development, physiological underpinnings, measurement techniques, and clinical relevance of central venous pressure (CVP) in perioperative and critical care settings. Although traditionally used as a marker for fluid responsiveness and intravascular volume status, evidence now emphasizes that CVP alone is unreliable for guiding fluid therapy. Nonetheless, when used alongside

Mechanical Ventilation

Automated mechanical ventilator design and analysis using neural network

Summary This study describes the design, simulation, and validation of an automated mechanical ventilator system using neural networks to optimize critical ventilation parameters. The ventilator specifically addresses clinical conditions such as pneumonia and chronic obstructive pulmonary disease (COPD). By employing feed-forward neural networks (FFNN) to regulate parameters like tidal volume, respiratory rate, and inspiration-to-expiration (I:E)

Revisiting Acute Respiratory Distress Syndrome ventilation management: Time for a paradigm shift focusing on tidal volume

Abstract: Merola and colleagues critically evaluate current Acute Respiratory Distress Syndrome (ARDS) ventilation strategies, emphasizing limitations inherent in universally applying low tidal volume (VT) strategies. They argue for personalized, physiology-driven ventilation approaches that incorporate mechanical power, compliance, and transpulmonary pressures. The authors highlight the complexity and heterogeneity of ARDS, suggesting the inadequacy of global parameters
