ABSTRACT
OBJECTIVE: To assess the Dixtal DX2710 automated oscillometric device used for blood pressure measurement according to the protocols of the BHS and the AAMI. METHODS: Three blood pressure measurements were taken in 94 patients (53 females 15 to 80 years). The measurements were taken randomly by 2 observers trained to measure blood pressure with a mercury column device connected with an automated device. The device was classified according to the protocols of the BHS and AAMI. RESULT: The mean of blood pressure levels obtained by the observers was 148±38/93±25 mmHg and that obtained with the device was 148±37/89±26 mmHg. Considering the differences between the measurements obtained by the observer and those obtained with the automated device according to the criteria of the BHS, the following classification was adopted: "A" for systolic pressure (69 percent of the differences < 5; 90 percent < 10; and 97 percent < 15 mmHg); and "B" for diastolic pressure (63 percent of the differences < 5; 83 percent < 10; and 93 percent < 15 mmHg). The mean and standard deviation of the differences were 0±6.27 mmHg for systolic pressure and 3.82±6.21 mmHg for diastolic pressure. CONCLUSION: The Dixtal DX2710 device was approved according to the international recommendations

A medida indireta da pressão arterial é menos precisa que a medida direta, mas é o método utilizado para o diagnóstico e tratamento da hipertensão arterial. Apesar de ser um procedimento relativamente simples, fácil de ser realizado e não invasivo, pode estar sujeito a erros. Este artigo enfatiza a técnica correta de medida indireta da pressão arterial e as possibilidades de erros relacionadas a equipamento, paciente, observador, ambiente e técnica.
