Study Arms:
- Nitric Oxide First, Oxygen Last (Type: EXPERIMENTAL): 10 minute dose of Nitric Oxide (NO) at 80 ppm, then 10 minute dose of NO plus Oxygen, then 10 minute washout, then 10 minute dose of 100% Oxygen on Day 1.
- Oxygen First, Nitric Oxide Last (Type: EXPERIMENTAL): 10 minute dose of 100% Oxygen, then 10 minute dose of NO plus Oxygen, then 10 minute washout, then 10 minute dose of NO at 80 ppm on Day 1.

Based on this trial design, predict the completion outcome and termination type (if applicable).
