Summary: The Zero to Five study demonstrated that a 0-minute wait before an AOBP measurement was closer to the awake ABPM result than a 5-minute wait.

Summary: This study compared the accuracy of two blood pressure readings with three readings in the diagnosis of hypertension and found that two readings may be sufficient unless there is a difference of at least 10mmHg between the systolic and diastolic readings.

Summary: This study found that systolic and diastolic pressure have different impacts on the diagnosis of hypertension, and factors such as age, race, and medical comorbidities also influence the diagnosis.

Summary: Non-invasive blood pressure measurements often underestimate systolic blood pressure and overestimate diastolic blood pressure. The study found that Korotkoff sounds accurately detect the onset of blood flow and closely coincide with diastolic blood pressure.

Summary: The study found that blood pressure measured with an unsupported back was slightly higher than supported back, with statistically significant difference in systolic pressure. Age and supported blood pressure levels have different impacts on blood pressure variation rate.

Summary: The study aimed to improve the perioperative allocation of correct NIBP cuffs in obese patients, with an intervention of educating staff on MAC-based cuff allocation. The correct cuff allocation rate increased from 22.5% to 75.0%, showing significant improvement. Staff surveys revealed mixed feelings about confidence in cuff selection and concerns about extra work involved in arm measurements.

Summary: The study found that the compression of the cuff during NIBP measurement can cause momentary changes in SpO(2), mainly leading to an increase in blood oxygenation level. These changes are not correlated with factors such as sex, age, height, body weight, BMI, HR, and blood pressure. Frequent NIBP measurements may result in misleading conclusions about SpO(2) levels.

Summary: In older individuals, cuff blood pressure fails to correctly identify isolated systolic hypertension compared to invasive blood pressure, indicating a need for improvement in cuff blood pressure measurements.

Summary: High systolic blood pressure is a major modifiable risk factor for death worldwide. Accurate blood pressure measurement is essential for screening, diagnosis, and management of hypertension. The World Health Organization report outlines technical specifications and recommendations for automated noninvasive clinical blood pressure measurement with cuff.

Summary: This research proposes an algorithm to preprocess photoplethysmography (PPG) and electrocardiogram (ECG) signals and apply them to deep learning for accurate continuous blood pressure monitoring. The algorithm includes several steps such as signal separation, randomization, Fourier transform, and normalization. The neural network trained with this algorithm achieves high accuracy in predicting continuous blood pressure.

Summary: This study investigates the anthropometric characteristics of the arm in a large population to identify the appropriate shape of the cuff for each arm. The results show that the conical shape of the arm increases with increasing arm circumference, and arm circumference, length, and sex are factors influencing the conical shape. Based on the calculated slant angle, dimensions for bladders that would appropriately fit the arm are provided.

Summary: This study investigated the differences between invasive arterial blood pressure (IABP) and noninvasive blood pressure (NIBP) measurements in critically ill patients with shock, finding that approximately 9% of shock patients had clinically-relevant mean arterial pressure differences. Higher serum lactate levels were associated with a higher likelihood of clinically relevant differences.

Summary: This study aimed to compare the agreement between cuff-based and invasively measured SBP amplification. The results showed differences between the two methods, with cuff-based estimates demonstrating systematic bias and less individual variability.

Summary: This paper studies arterial deformation under cuff pressure in cuff-based blood pressure measurement using a collapse model, revealing the effects of arterial stiffness on measured blood pressure. The results have implications for improving the accuracy of cuff-based BP measurement in the future.
