4. positive response to inhaled NO, defined as a decrease in MPAP of at least 2 mmHg and an increase in PaO 2 (FiO 2 1.0, PEEP 10 cmH 2 O) of at least 40 mmHg after NO inhalation at an inspiratory concentration of 15 ppm.
When 0-5 ppm was selected, calibration was performed using a tank of NO with a reference concentration of 0.945 ppm (CFPO, Air Liquide, France); when 0-200 ppm was selected, calibration was performed using a tank of NO with a reference concentration of 22.
Because concentrations of 45 and 150 ppm were associated with a longlasting increase in blood methemoglobin concentration, which interfered with the calculation of venous and arterial O 2 content and pulmonary shunt, they were not included in the randomization, but were always administered as the last concentrations.
As shown in Tables 4and 5, NO induced a significant dose-dependent decrease in MPAP, SPAP, DPAP, PVRI,RVSWI and Q VA /Q T with a significant and dose-dependent increase in PaO 2 /FiO 2 . As shown in Figs 1, 2, 3, a plateau effect was observed at inspiratory NO concentrations of 4.5 ppm for MPAP, PVRI, Q VA /Q T and PaO 2 /FiO 2 . All other hemodynamic and respiratory parameters did not vary significantly.
Methylene chloride exposure study results were not available, but according to the company, measured methylene chloride exposure levels were "an order of magnitude below the standard," which at the time would have been a Permissible Exposure Limit of 1736 mg/m 3(500 ppm).
