OBJECTIVE: To evaluate the noise levels with high-frequency oscillatory ventilation and conventional mechanical ventilation.
DESIGN: An observational, prospective study.
SETTING: Pediatric intensive care unit.
SUBJECTS: The caretakers and environment of the pediatric intensive care unit.
INTERVENTIONS: High-frequency oscillatory and conventional mechanical ventilation.
MEASUREMENTS AND MAIN RESULTS: Caretakers evaluated noise using a visual analog scale. Noise was measured with a decibel meter and an octave band frequency filter. There was twice as much noise perceived by the caretakers and as measured on the decibel A scale. All measures showed significantly greater noise, especially at low frequencies, with high-frequency oscillatory ventilation.
CONCLUSIONS: High-frequency oscillatory ventilation exposes the patient to twice as much noise as does the use of conventional mechanical ventilation.
