Oxytocin is an endogenous peptide hormone that is synthesized in the hypothalamus and secreted by the posterior pituitary gland. It promotes uterine contraction by binding to G-protein-coupled oxytocin receptors on myometrial cells, thereby increasing intracellular calcium and enhancing actin-myosin interaction. In obstetric practice, oxytocin is administered after the delive...

The administration of inhaled anesthetics depends on diffusion from the lungs into the blood and the brain. Classical pharmacokinetic–pharmacodynamic (PK-PD) models treat this as deterministic, assuming uptake and washout produce consistent effects. In practice, however, both the movement of gas through the lungs and the timing of emergence vary widely, influenced by turbulen...
