Sepsis refers to a systemic inflammatory response syndrome resulting from a microbial infection, and can be simulated by a surgical technique termed cecal ligation and puncture (CLP). Here we describe a method to use CLP-induced animal model to screen medicinal herbs for therapeutic agents.

Repeated pulmonary lavages in anesthetized pigs induce lung injury resembling major aspects of human acute respiratory distress syndrome (ARDS). For this purpose the lungs are repeatedly lavaged with 0.9% saline at 37 °C. The goal of the protocol is a reproducible mitigation of gas exchange and hemodynamics for research in ARDS.

Experimental sepsis can be induced in mice using the cecal ligation and puncture (CLP) method. Current protocols to assess autophagy in vivo in the context of CLP-induced sepsis are presented here: A protocol for measuring autophagy using (GFP)-LC3 mice, and a protocol for measuring autophagosome formation by electron microscopy.

Here, we present a protocol for bedside POCUS application in ARDS management within the ICU. It details standardized techniques for lung, cardiac, diaphragm, venous, and gastric assessments to guide ventilation, predict weaning, and prevent complications.
FAQs
The pulmonary endothelium and alveolar epithelium normally help contain fluid within the circulation and air spaces. In sepsis-associated ARDS, dysregulated immune signaling damages both barriers, increasing vascular permeability. This allows protein-rich fluid to enter the alveoli, where it interferes with normal gas exchange and contributes to severe hypoxemia and diffuse inflammatory injury.
Protein-rich fluid accumulating in the alveoli creates an abnormal environment for oxygen transfer. Along with diffuse lung inflammation, this accumulation disrupts the pulmonary surface responsible for exchanging gases, so oxygenation becomes severely impaired. The resulting hypoxemia explains why respiratory support becomes an important part of management while clinicians also address the underlying sepsis.
Dysregulated immune signaling connects the systemic effects of sepsis with local pulmonary damage. Rather than preserving the vascular and epithelial barriers, the inflammatory response injures them and increases permeability. This mechanism helps explain how an infection outside the lungs can produce diffuse lung inflammation and provides a rationale for investigating targeted therapies that modify harmful inflammatory pathways.
Clinicians should consider this complication when a patient with sepsis develops life-threatening impairment of oxygen exchange together with evidence of diffuse inflammatory lung injury. Recognition is important because the respiratory problem requires prompt management, not only treatment of infection. Early identification can therefore support coordinated care aimed at oxygenation, lung protection, and control of the underlying cause.
Management requires attention to both the injured lungs and the infection driving the systemic illness. Respiratory care includes lung-protective ventilation, while treatment of the underlying infection addresses the initiating medical problem. Using these priorities together is intended to limit additional pulmonary stress, support oxygen exchange, and improve care for critically ill patients at risk of poor outcomes.
This condition provides a clinical model for studying how systemic infection disrupts pulmonary barriers. Research focuses on identifying biomarkers, developing targeted therapies, and designing strategies that may reduce mortality in critically ill patients. These efforts connect observations at the level of endothelial and epithelial injury with practical goals such as earlier recognition, more precise treatment, and improved respiratory outcomes.
