Nitric oxide can be administered by a few different ways. When a patient is on a ventilator, nitric oxide is nebulized on the inspiratory cycle. Nitric oxide can also be given by a facemask or even a nasal cannula. The normal ranges for nitric oxide is 1 – 80 parts per million. High levels of nitric oxide can be very harmful and may even cause death, pulmonary edema or methemoglobinemia. A high concentration would be considered to be between 5,000 and 20,000 ppm. The length of time that the nitric oxide was given varies (cite). The treatment length is individualized based on patient condition. In pediatric patients it showed that anything greater than 20 parts per million had no additional benefits and possibly could have increased
