Q: What is the major concern when inhaled nitric oxide (iNO) is administrated via nasal prong, face mask or Non-invasive positive pressure (NIPPV) mask?
Answer: iNO and its derivatives NO2 have direct cytotoxic effects particularly to alveolar and vascular tissue. NO released into the environment can be potentially toxic. If iNO is administered by nasal prongs, face mask or NIPPV than it should be done in a well-ventilated area.
