Abstract<\/h3>\n

Not all patients with refractory hypoxemia meet ECMO criteria \u2014 yet many still face catastrophic oxygenation failure with limited options. This study describes a physiology-guided \u201cLung Rescue Team (LRT)\u201d model<\/strong>, designed to evaluate patients who are ineligible or borderline for ECMO by integrating mechanical ventilation physiology, multimodal imaging, hemodynamics, gas exchange, and lung recruitability profiling<\/strong>.<\/p>\n

The LRT uses structured algorithms to characterize the mechanism of hypoxemia<\/strong> (shunt, low VA\/Q, dead space, or low EELV), identify reversible physiology<\/strong>, and apply targeted rescue strategies including personalized PEEP titration, recruitment assessment, prone positioning, inhaled pulmonary vasodilators, right-ventricular optimization, and extracorporeal \u201calternatives.\u201d<\/p>\n

This approach provides a reproducible framework for managing patients who cannot access ECMO but remain at high risk of death, focusing on physiology restoration instead of escalating support blindly<\/strong>.<\/p>\n

\ud83d\udd0d 10 Key Insights<\/h2>\n

1\ufe0f\u20e3 Not All Severe Hypoxemia Is the Same \u2014 Mechanisms Matter<\/h3>\n

The LRT approach begins with classifying hypoxemia based on mechanism<\/strong>, not severity alone. Using ABGs, lung mechanics, EIT, CT imaging, and bedside ultrasound, the team identifies whether the dominant driver is shunt, low VA\/Q mismatch, derecruitment, dead space ventilation, or circulatory impairment<\/strong>.<\/p>\n

2\ufe0f\u20e3 A Dedicated Lung Rescue Team Bridges the Gap When ECMO Is Not an Option<\/h3>\n

Many patients were too old, too frail, too comorbid, or too late in their disease trajectory to qualify for ECMO. The LRT framework offers an organized multidisciplinary alternative<\/strong>, integrating intensivists, respiratory therapists, cardiologists, imaging specialists, and ECMO clinicians into one cohesive decision-making unit.<\/p>\n

3\ufe0f\u20e3 Recruitability Drives Ventilator Strategy \u2014 Not Fixed Protocols<\/h3>\n

LRT evaluation emphasizes recruitability testing<\/strong>, using tools such as:<\/p>\n
