Blood pressure measurements are one part of a circulatory assessment (Docherty and McCallum 2009). Treatments for raised or low blood pressure may be initiated or altered according to blood pressure readings; therefore correct measurement and interpretation of blood pressure is an important nursing skill. Blood pressure should be determined using a standardized technique in order to avoid discrepancies in measurement (Torrance and Serginson 1996). Both manual and automated sphygmomanometers may be used to monitor blood pressure. The manual auscultatory method of taking blood pressure is considered the gold standard (MRHA 2006), as automated monitoring can give false readings (Coe and Houghton 2002), and automated devices produced by different manufacturers may not give consistent figures (MRHA 2006). So, although automated sphygmomanometers are in common use within health care settings in the UK, the skill of taking blood pressure measurement manually is still required by nurses. As a fundamental nursing skill, blood pressure measurement, using manual and automated sphygmomanometers, and interpretation of findings are often assessed via an OSCE. Within this chapter revision of key areas will allow you to prepare thoroughly for your OSCE, in terms of practical skill and understanding of the procedure of taking blood pressure. Blood pressure is defined as the force exerted by blood against the walls of the vessels in which it is contained (Docherty and McCallum 2009). A blood pressure measurement uses two figures—the systolic and diastolic readings. The systolic reading is always the higher figure and represents the maximum pressure of blood against the artery wall during ventricular contraction. The diastolic reading represents the minimum pressure of the blood against the wall of the artery between ventricular contractions (Doughetry and Lister 2008). You will need to be able to accurately identify systolic and diastolic measurements during your OSCE. When a blood pressure cuff is applied to the upper arm and inflated above the level of systolic blood pressure no sounds will be detected when listening to the brachial artery with a stethoscope. The cuff clamps off blood supply. As the cuff is deflated a noise, which is usually a tapping sound, will be heard as the pressure equals the systolic blood pressure —this is the first Korotkoff ’s sound.

Significant Difference

Indirect blood pressure measurements were compared in 28 conscious cats using Doppler and oscillometric blood pressure-measuring devices. Ten cats were used to compare Doppler measurements between two examiners and 18 cats were used to compare Doppler and oscillometric measurements. The Doppler machine obtained systolic and diastolic blood pressure readings in 100% and 51% of attempts, respectively. With the oscillometric machine, systolic and diastolic blood pressure readings were obtained in 52% of the attempts. With the Doppler, measures of mean systolic blood pressure between two examiners were positively correlated, but there was no correlation for diastolic blood pressure measures. When comparing the results obtained by Doppler and oscillometric machines there was no significant difference between mean systolic blood pressure readings, but the oscillometric machine produced significantly higher estimates of diastolic blood pressure. In both cases, the standard deviations for the oscillometric machine were considerably larger than those for the Doppler machine. The first reading of systolic blood pressure obtained with the Doppler machine was an excellent predictor of the mean of five readings, but this was not so for the oscillometric machine. It took less than 5 min to obtain five readings in 37.5% of cases with the Doppler machine but this was true for only 5% of cases with the oscillometric machine. Two cats with ophthalmological lesions consistent with systemic hypertension were identified. In these two patients, systolic blood pressure measurements were between 200 and 225 mmHg when measured by Doppler, and between 140 and 150 mmHg when measured by the oscillometric machine. This suggests that a lower reference range for normal systolic blood pressure values should be used for the oscillometric device.
