Avaliação das condições de uso de esfigmomanômetros em serviços hospitalares

Abstract

Objective: To evaluate the conditions of sphygmomanometers in use at public and private hospitals. Methods: A descriptive study using a quantitative approach, undertaken in four major hospitals in the State of São Paulo, in the period between 2009 and 2010. The aneroid manometers were tested against a calibrated mercury manometer. They were considered out of calibration when the differences were ≥ 4 mmHg. Results: We assessed 162 sphygmomanometers (78 in a public hospital and 84 from philanthropic and private institutions) and 98.1% were of the aneroid type. It was verified that 56.2% of the manometers were not calibrated (48.6% of private hospitals and 63.1% of public hospitals). Analyzing the mean differences of negative decalibration, there was a significant difference between the manometers of the private hospital and the public hospitals (-6.14 ± 2.66 mmHg vs. -8.97 ± 6.74 mmHg, respectively, p <0.05). It was also observed that in 70.2% there was no periodic evaluation made, 26.7% had aged rubber extension, 20.5% presented leaking valves, and 27% of the manometers did not rest with the pointer on the zero mark. Conclusion:The decalibration of the aneroid sphygmomanometers was significant and may lead to incorrect evaluation of blood pressure.

Métodos: Estudo descritivo de abordagem quantitativa realizado em quatro hospitais de grande porte do Estado de São Paulo, no período entre 2009 e 2010. Os manômetros aneroides foram testados contra manômetro de mercúrio calibrado. Foram considerados descalibrados quando as diferenças foram ≥ a 4 mmHg. Resultados: Foram avaliados 162 esfigmomanômetros, (78 de um hospital público e 84 de instituições filantrópicas e privada) e 98,1% eram do tipo aneróide. Verificou-se que 56,2% dos manômetros estavam descalibrados (48,6% do hospital privado e 63,1% dos hospitais públicos). Analisando-se as médias das diferenças negativas da descalibração, houve diferença significativa entre os manômetros do hospital privado e os dos hospitais públicos 14±2,97±6,74 mmHg, respectivamente, p<0,05). Observou-se ainda que em 70,2% não era feita avaliação periódica; 26,7% tinham extensão de borracha envelhecida; 20,5% das válvulas apresentaram vazamento; e 27% dos manômetros não estavam com o ponteiro na marca zero. Conclusão A descalibração dos esfigmomanômetros aneróides foi expressiva e pode acarretar avaliação incorreta da pressão arterial.

Improvement in Semiconductivity On The Measurement Of Blood Pressure After An Educational Intervention In Health Professionals

“…These evidences are based on a study on the evaluation of the conditions of the use of sphygmomanometers in health services, which revealed that most respondents (76.6%) did not know how often the aneroid apparatus should be calibrated. 7 It is also worth noting that 0% of the participants knew how to evaluate the calibration of the automatic devices because they were not available in the institution. Therefore, since there is a current tendency to replace aneroid devices by automatic devices, it would be extremely important that trainings are carried out in order to prepare professionals to deal with this novelty.…”
