An intelligent ventilation and oxygenation management system in neonatal intensive care using fuzzy trend template fitting.

abstract：:We tested the hypothesis that transmission of arterial pressure to brain tissue oxygenation is low under conditions of arterial pressure instability. Two experimental models of hemodynamic instability were used in healthy human volunteers; (1) oscillatory lower body negative pressure (OLBNP) (N = 8; 5 male, 3 female),...
