  1. Occupational exposure during nitric oxide inhalational therapy in a pediatric intensive care setting.

    Article - En anglais

    Objective 

    To determine the amount of occupational exposure to nitric oxide (NO) and nitrogen dioxide (NO2) during NO inhalational therapy.

    Design 

    In a standard pediatric intensive care room, 800 ppm NO was delivered to a high-frequency oscillator and mixed with 100% O2 to obtain 20 ppm NO in the inspiratory gas flow.

    NO and NO2 concentrations in room air were measured using a chemiluminescence analyzer.

    Air samples were taken from a height of 150 cm at a horizontal distance of 65 cm from the ventilator in a nonventilated and in a well-ventilated room with and without an expiratory gas exhaust under normal intensive care environmental conditions.

    Setting 

    Pediatric intensive care unit in a university children's hospital.

    Measurements and results 

    Maximal concentrations of NO and NO2 were reached after 4 h NO use.

    Without exhaust, in a nonventilated room, environmental NO and NO2 concentration rose to a maximum of 0.462 and 0.064 ppm, respectively.

    With the use of an expiratory gas exhaust, NO and NO2 concentrations were 0.176 and 0.042 ppm, respectively.

    With normal air-conditioning, these values were 0.075 and 0.034 ppm, respectively, without the use of an expiratory gas exhaust.

    With expiratory gas exhaust added to normal air-conditioning, values for NO and NO2 were 0.035 and 0.030 ppm, respectively. (...)
