“…Two studies addressed the effect of placing the stethoscope under the cuff during auscultation (Supplementary Table 19) [ 288 , 289 ]. They reported small but significant increases in measured SBP and small-to-moderate decreases in measured DBP, when compared with placing the stethoscope in the recommended position outside the cuff (Table 2 ).…”

“…Most previous practitioners of sphygmopiezophonometry chose to place the microphone inside the cuff [3][4][5][6]17,20], since this affords better protection against ambient noise. However, a study by Weber and coworkers [27] revealed that auscultation of the K-sounds inside the cuff and in the cubital fossa yield significantly different values of sbp and dbp; this is why we decided to affix the microphone where the stethoscope is located during a conventional measurement. We have shown above that, armed with modern means of recording and analyzing the basic data (sound and pressure) and the idea of coincidence exploited so far only by Gilford [1], the approach pioneered by Riva-Rocci and Korotkoff can be transformed into a totally objective, trustworthy procedure in which the microphone is placed outside the cuff, exactly where the stethoscope is positioned for auscultation.…”

A noninvasive method for monitoring blood pressure, based on the principles established by Riva-Rocci and Korotkoff (K), is described; it furnishes, after a single compression-deflation cycle of the arm-encircling cuff, values of systolic and diastolic blood pressures as well as the contours of the brachial arterial pulse and the corresponding volume pulse. K-sounds are detected by a single microphone situated in the cubital fossa, and the time-varying cuff pressure P(t) is read by a piezoresistive pressure sensor. The behavior of P(t) during deflation is resolved into two parts, P(t)=p(t)+b(t); p is a train of positive going pulses (arising from arterial pulsations), whereas b is a slowly changing baseline. Noise pulses in the microphone output are rejected by using the observation that the first few K-sounds are emitted when p is close to a maximum, and the last few when dp/dt is close to a maximum. The performance of the instrument is illustrated by showing how it copes with ambient noise and involuntary manual perturbations of P, and by presenting contours of various pulses.

“…The practice was assessed by a checklist with the items of a standardized measurement method which was also constructed based on the review of the literature [1,6,24,25,[14][15][16][19][20][21][22][23]. The participant nurses were required to report whether they always adhere to each of the 20 items during blood pressure measurement.…”

KEYWORDSHypertension, Accurate blood pressure measurement, Blood pressure measurement, Blood pressure, Theory of planned behaviour 2 Abstract Patients under anthracycline chemotherapy are at risk of cardiovascular disorders, including hypertension. Error in blood pressure measurement exceeding 5mmHg may have detrimental outcomes to the patient quality of care. Studies involving nurses reveal discrepancies in knowledge and practices, which raise questions on the reliability of their BP recordings. It is not clear whether nurses taking care of these patients have sufficient knowledge and compliance regarding accurate blood pressure measurement. This study aimed at assessing knowledge, practice and associated factors regarding accurate blood pressure measurement procedures among nurses caring for cancer patients under anthracycline chemotherapy in Tanzania, guided by the Theory of Planned Behavior and Neuman's Prevention and Intervention Theory.Methods A cross-sectional study, with a quantitative approach was conducted among 181 nurses who were conveniently sampled from various hospitals in Tanzania. A structured questionnaire was used for data collection and analysis done by using statistical package for social sciences (SPSS) version 21. Descriptive statistics, Chi-square and Binary logistic regression analysis were applied.Results Based on the given 18 items to assess nurses' knowledge of accurate blood pressure measurement, the mean knowledge score was 8.6 (SD=3.6), implying poor knowledge. Those with a bachelor of Nursing and above were more knowledgeable than those with a diploma and below (AOR=2.5, 95%CI=1.281-4.914, p=0.007). Out of the maximum practice score of 40, the nurses had Mean=16 (SD=2.33) implying poor practice. Three mostly reported barriers were: Feeling unempowered, Nurses' workload, and unconducive working environment. The results conform to the theory of planned behavior and Neuman's Prevention and Intervention Theory. Conclusion Nurses caring for patients in anthracycline chemotherapy in Tanzania have poor knowledge and poor practice regarding accurate blood pressure measurement.Institutional programs to educate nurses about accurate blood pressure measurement may have an impact on attitude and intention to practice accurate blood pressure measurement.Considering the barriers to accurate blood pressure measurement, and the impact of unstable blood
