Introduction Hyperventilation, defined as an increase in alveolar ventilation that exceeds metabolic CO₂ production, leads to arterial hypocapnia (PaCO₂ < 35 mmHg) and a cascade of neuro‑vascular and metabolic effects (Brown & Smith, 2021). While often benign, severe or prolonged episodes can precipitate cerebral vasoconstriction, tetany, arrhythmias, and, in extreme cases, loss of consciousness (Klein et al., 2020).

Current clinical practice typically categorizes hyperventilation into , metabolic , and neurologic types (American Thoracic Society, 2019). However, this taxonomy does not capture the multidimensional nature of the response, which involves intertwined ventilatory, autonomic, thermoregulatory, and respiratory‐muscle components. ¹ Department of Pulmonary Medicine

The Hyperventilation 5 VOSTFR‑ model provides a robust, physiologically grounded classification that enables rapid, targeted therapy, markedly shortening the time to biochemical and clinical recovery. Implementation in emergency settings may improve patient outcomes and reduce resource utilization. Country ² Department of Emergency Medicine

Each axis can be scored (0 = absent, 1 = mild, 2 = moderate, 3 = severe) yielding a composite (0–15). The suffix “‑” denotes the presence of a dominant axis (the one with the highest individual score) that guides therapeutic priority.
