摘要
Nitric oxide (NO) is a biologically active molecule approved for the treatment of pulmonary hypertension in newborn patients. Commercially available NO delivery systems use pressurized cylinders as the source of NO and a sensor to control the concentrations of NO and nitrogen dioxide (NO2) delivered. Cylinder-based delivery systems are safe and widely used around the world, but they are bulky, expensive, and reliant on a robust supply chain. In the past few years, novel NO generators and delivery systems have been developed to overcome these limitations. Electric NO generators produce NO from ambient air using high-voltage electrical discharge to ionize air, which leads to the formation of NO, NO2, and ozone (O3). A scavenging system is incorporated to reduce the concentration of the toxic byproducts generated in this type of system. NO can also be generated by the reduction of NO2 by ascorbic acid or released from liquid solutions or solid nanoparticles. The development of easy-to-use, safe, and portable NO delivery systems may enable the delivery of NO in the out-patient setting or at home. Furthermore, non-cylinder-based NO generators reduce the cost of NO production and storage and may therefore make NO delivery feasible in low-resource settings. Here we review commercially available systems that can generate and administer inhalable NO.
