Development of intelligent NO delivery system cooperating with ventilator / 医疗卫生装备

ABSTRACT

This paper develops an intelligent NO delivery system cooperating with the ventilator to make NO inhaled safely, reliably, conveniently and economically, which is based on correlation between the parameter setup of the ventilator and the concentration of NO. The circuit control system consists of a mass flow controller and a CPU mainly. A mixing unit is designed to mix NO with the gas from the ventilator uniformly. Clinical experiments show that the NO from the intelligent delivery system can decrease PH and increase SaO2 with the concentration of generated NO2 less than 5ppm.
