Electrically generated nitric oxide

Inhaled nitric oxide (NO) is a selective pulmonary vasodilator approved by the US Food and Drug Administration in 1999 for the treatment of persistent pulmonary hypertension of the newborn [ 1]. The current NO delivery system is large, heavy, cumbersome and expensive, requires a cylinder distribution network and a device to regulate NO levels, monitor nitrogen dioxide (NO 2), percent of O 2, and trained respiratory therapy staff. Several methods have been used to produce NO for biomedical applications, including chemical and electrical systems. However, these methods produce large amounts of NO 2 and ozone (O 3) toxic byproducts, requiring complex purification systems. Recently, we designed, developed, and tested a lightweight, portable, economical device generating NO by pulsed electrical discharge in air using a high-voltage resonant power supply, to produce low levels of NO 2 and O 3 [ 2]. The electrodes are powered by a microcontroller circuit. Energy...
