Avaliação do ruído em Unidades de Terapia Intensiva

Abstract

Int ensive Care Units are environments with numerous noise sources. In different hospital environments it is recommended to have a sound pressure level between 35 and 45db(A). Aim: To measure the sound pressure levels in three ICU at a hospital in Jundiaí, State of São Paulo, Brazil. Study Design: Observational. Materials and Methods: we used a Minipa model MSL1532C (USA) sound meter, according to the Brazilian Technical Standards (NBR 10151), in order to measure sound levels in the ICUs at different moments, that is, the morning, afternoon and night at peak times of activity. Results: The values found during the checking of the sound pressure levels were 64.1dB (A) in the First ICU, 58.9 dB (A) in the Coronary Unit and 64dB (A) in the second ICU. Conclusion: High sound pressure levels in ICU still mean an important health-related problem for patients in these units. None of the three ICU pad levels above 85dB, showing that there is no occupational risk for the health care teams in the environments studied.

Tinnitus was reported by 29.47%.…”

“…Numberless studies have indicated the extreme noise in several hospital environments, and pointed out the need for prevention, as well as, for proper guidance for the professionals, particularly regarding those involved with the area of health, where, theoretically, the awareness for silence should be of major importance [2][3][4][5][6][7] .…”
