“…PPG is used in a number of non-invasive instruments to monitor different parameters, such as pulse rate and respiratory rate (LINDBERG et al, 1992;JOHANSSON et al, 1999), blood perfusion (KAMAL et al, 1989), arterial oxygen saturation (TREMPER and BARKER, 1989) and blood pressure (YAMAKOSHI and KAMIYA, 1987;YAMAKOSHI, 1991;CHAWLA et al, 1992;FRONEK et al, 1994;LANGBAUM and EYALL, 1994).…”

Photoplethysmography (PPG) can be used to measure systolic blood pressure at the brachial artery. With a specially designed probe, positioned in the most distal position beneath a pressure cuff on the upper arm, this is possible. The distance between the light source (880 nm) and the photodetector was 20 mm. A test was performed on neuro-intensive care patients by determining blood pressure from the PPG curves, and, when it was compared with systolic blood pressure obtained from inserted indwelling arterial catheters, a correlation factor of r = 0.95 was achieved. The difference between blood pressure obtained using PPG and invasive blood pressure measurement was 3.9 +/- 9.1 mmHg (mean +/- SD), n = 19. The depth to the brachial artery was 13.9 +/- 4.1 mm (mean +/- SD), n = 18. A digital PPG system utilising pulsating light was also developed.

“…In nearly 95% of cases, the differences between BP AV and conventional methods were likely to be within ± 14 mm Hg. 13 Using an average of two SBP estimations as in this study is time-consuming, and eliminates the advantage of an earlier response time attained in our study.…”

“…Mean (SD) time A limited number of studies have utilised Bland-Altman analysis. 5,13,16,17 A study done by Chawla et al evaluated the use of pulse oximetry to accurately monitor systolic blood pressure in 100 healthy volunteers. Using the oximetry method, they estimated arterial blood pressure at the disappearance of the waveform during manual blood pressure cuff inflation, at the reappearance of the waveform during manual cuff deflation, and by averaging the two estimations (BP AV ).…”

“…[10][11][12][13][14][15][16][17] However, most of these studies assessed the degree of correlation between the different methods [10][11][12]14,15 and, as Bland and Altman have pointed out, the more relevant comparison should involve the establishment of the limits of agreement. 18 Most also used a manual BP cuff, which allowed control of the rate of inflation and deflation of the cuff, resulting in moderately accurate results with good correlation.…”

Background:The estimation of systolic blood pressure by disappearance and reappearance of the pulse oximeter trace during cuff inflation and deflation was compared with non-invasive blood pressure (NIBP) measurement, across the range of body mass index (BMI), during spinal anaesthesia for Caesarean section. Methods: Seventy-five parturients were recruited, with BMI of < 30 (Group 1), 30-40 (Group 2), and > 40 kg/m 2 ((morbidly obese, Group 3). A non-invasive blood pressure monitor was used with the pulse oximeter probe on the ipsilateral arm. Estimations were done before induction and 5 min after induction of spinal anaesthesia, during cuff inflation and deflation. Bland and Altman analysis was performed and the concordance correlation coefficient (r) estimated. Results: For estimation of systolic blood pressure during cuff inflation under spinal anaesthesia in Groups 1, 2 and 3: r = 0.57, 0.74 and 0.91; bias = -0.4, -2.9 and 0.8 mmHg, and limits of agreement = -27.7 to 26.9, -27.7 to 21.9, and -15.9 to 17.5 mmHg respectively. The mean (SD) time saved by estimation during inflation compared with measurement in Groups 1, 2 and 3 was 22.8 (13.2) s, 30.0 (11.6) s and 33.0 (15.6) s respectively. In Group 3, the percentage error was ± 13% of mean systolic blood pressure. Conclusions: Estimation of systolic blood pressure during cuff inflation under spinal anaesthesia in the morbidly obese is more precise than in lower BMI parturients. Time to estimation is relevantly shorter than measurement. This could improve patient safety by rapid and accurate identification of hypotension in these high-risk patients. This estimation method is associated with limits of agreement that may be clinically significant even in morbidly obese patients, and should not be considered a replacement for subsequent NIBP measurement.

“…A gradual deflation was started in 5-mmEIg decrements until the waveform reappeared. The average of both values was recorded as the systolic blood pressure [3]. Several measurements showed values varying from 180 to 200 mmHg.…”
