Synthesize comparative evidence on hypoxia tolerance, oxygen transport, and oxygen consumption across humans, rats, and mice to determine the validity of translating rodent hypoxia models to human clinical settings.
Narrative review summarizing comparative physiological, anatomical, and molecular data on hypoxia responses across humans, rats, and mice.
Evaluation of pulmonary gas exchange, mitochondrial plasticity, and mass-dependent oxygen utilization during hypoxic stress.
Mice exhibit robust hypoxia tolerance via enhanced pulmonary gas exchange, metabolic downregulation, and pronounced mitochondrial electron transport system plasticity.
Rats display marked susceptibility to hypoxic stress, presenting with pathological complications including right ventricular hypertrophy, excessive erythropoiesis, and myocardial injury.
Quantitative body-mass scaling and qualitative physiological distinctions indicate that rodent responses to hypoxia cannot be directly extrapolated to human therapeutic strategies without careful species-specific adjustments.
