An impedance plethysmographic method for measuring systolic and diastolic blood pressures in small infants using standard electro-cardiogram recorders has been studied. The overall 95% confidence limit of the mean of five estimations was found to be ±3.74 mm Hg for the systolic and ±3.72 mm Hg for the diastolic value. Comparing this method with intra-arterial measurements gave correlation coefficients (r) of 0.95 (bias 10.09 mm Hg) for systolic pressure and 0.89 (Bias 10.09 mm Hg) for diastolic pressure. Values for the comparison with auscultation were 0.98 (bias 19.29 mm Hg) systolic and 0.86 (bias 10.17 mm Hg) diastolic, and for the comparison of the arithmetic mean value with the flush method 0.84 (bias 30.17 mm Hg). These results reveal a good correlation with the intra-arterial measurements and indicate that this technique can be used for the periodic or continuous blood pressure monitoring of infants.

Introduction Ambulatory blood pressure monitoring (ABPM) has been proposed as the most effective way to characterize a person’s BP profile. However, there are very limited data in the literature comparing two simultaneously worn ABPM devices. Therefore, we compared an eight hour daytime simultaneous ABPM using two monitors (Mobil-O-Graph [I.E.M., Stolberg, Germany] and Spacelabs 90207 [Spacelabs Medical, Issequah, WA]). Methods Simultaneous BP and heart rate data were measured on 13 adult volunteers at the University of Pennsylvania using the two monitors over an 8 hour period. Other demographic data were also collected. Standard seated BPs were obtained in triplicate at the beginning and end of the 8 hour monitoring period using an Accutor (Datascope, Mahwah, NJ) device. Three blood pressures were obtained at 1 minute intervals, recorded and averaged for each arm using the Accutor device. Results The data show high concordance of measured mean arterial pressures (Mobil-O-Graph 101.4 [SEM-2.0] mmHg, Spacelabs 100.6 [SEM-2.4] mmHg) and heart rates (Mobil-O-Graph measuring 82.4 [ SEM- 4.1] beats/minute, Spacelabs 81.7 [4.0] beats/minute) between the monitors. Spacelabs measured a 10 mmHg higher systolic pressure (p=0.0016) and a non-statistically significant, but numerically higher (2.8 mmHg) diastolic pressure (Figure 1). Conclusion The systolic BP difference between the two devices has public health importance. These differences if confirmed in larger cohorts, ABPM manufacturers should consider developing a normative database to help practitioners interpret ABPM data obtained with their device.

Abstract - At the beginning of 2020 the world was shocked by the presence of a virus that attacks the respiratory tract, a virus known as Coronavirus Disease-2019 (Covid-19). Based on this problem, how does the system detect Covid-19 suspects based on blood pressure. In this study, researchers used a survey method which directly took data in the hospital. Therefore, the optimization of the MPX5700AP pressure sensor has been successfully made. At this time the researchers conducted a study that used the oscillometer method to measure blood pressure supported by Arduino Uno, which in waves will produce systolic and diastolic blood pressure. Blood pressure monitoring is made capable of measuring blood pressure in the range of 40-240 mmHg and this system has a systolic pressure error of 4.024 mmHg, while the diastolic pressure error is -0.408 mmHg.

Anaesthesia of 2 five-year-old femaleAfrican elephants (Loxodonta africana) was required for dental surgery. The animals were each premedicated with 120 mg of azaperone 60 min before transportation to the hospital. Before offloading, 1 mg etorphine was administered intramuscularly (i.m.) to each elephant to facilitate walking them to the equine induction / recovery room. For induction, 2 mg etorphine was administered i.m. to each animal. Induction was complete within 6 min. Surgical anaesthesia was induced with halothane-in-oxygen after intubation of the trunk. During surgery the mean heart rate was 61 and 45 beats / min respectively. Systolic blood pressures increased to 27.5 and 25.6 kPa respectively, and were treated with intravenous azaperone. Blood pressure decreased thereafter to a mean systolic pressure of 18.1 and 19.8 kPa, respectively. Rectal temperature was 35.6 and 33.9 oC at the onset of surgery, and decreased to 35.3 and 33.5 oC, respectively, at the end of anaesthesia. Etorphine anaesthesia was reversed with 5mg diprenorphine at the completion of 90 min of surgery.

Abstract BACKGROUND: Corticosteroids are still a cornerstone in multiple myeloma (MM) therapy, both as a single agent and as a part of many protocols, including VAD regimen (vincristine, adriblastine, dexamethasone). Corticosteroids are known to be involved in blood pressure (BP) regulation and to affect this parameter. The impact of dexamethasone (Dex) administration on BP in MM patients during VAD protocol treatment is poorly documented. AIM: The purpose of the study was to evaluate the blood pressure changes during Dex administration in patients treated with VAD protocol due to MM. METHODS: Thirteen patients with MM (7 men and 6 women; mean age 62,45 ± 8,14) were assessed. Primary hypertensive patients (7 persons) were not excluded. They were administered Dex in standard dose of 40 mg (day 1–4, 9–12, 17–21) according to VAD protocol. Blood pressure was assessed by the use of commercially available instruments of Ambulatory Blood Pressure Monitoring (ABPM). The BP recordings lasted 48 hours, were started on the day before the first day of VAD and were obtained every 10 minutes during mornings, every 15 minutes during the rest of days and every 20 minutes during nights. Average of systolic and diastolic blood pressure (SBP/DBP) were estimated for the 2-hour time before Dex and for the 14-hour time in the 2-hour periods after Dex. Minimal and maximal range of SBP/DBP increase and the mean amount of SBP/DBP increase were also determined. RESULTS: 48-hour BP recordings revealed a significant increase in systolic and diastolic blood pressure after Dex administration in all patients. SBP and DBP began to increase after 3 hours after Dex, then rose continually and reached the peak in the period from 6 to 10 hour after Dex. In comparison to 2-hour period before Dex, in which SBP/DBP amounted 139,63/82,92 ± 23,47/9,38 mmHg, the mean SBP/DBP increase rate was: in the 2–4 hour period after Dex - 146,68/88,15 ± 24,38/10,51 mmHg (p<0,05), in the 6–8 – 148,07/92,66 ± 14,07/9,04 mmHg (ns), in the 8–10 – 147,8/87,99 ± 14,07/9,04 mmHg (p<0,01), in the 10–12 – 143,44/86,12 ± 17,22/9,77 mmHg (p<0,05) and in the 12–14 – 144,47/88,59 ± 17,04/12,54 mmHg (p<0,01). The minimal range of SBP/DBP increase was 10,50/−2,00 mmHg, maximal range of SBP/DBP increase was 35,43/40,00 mmHg and the mean amount of SBP/DBP increase was 20,06/11,6 ± 8,36/14,23 mmHg. CONCLUSION: Our preliminary study revealed that Dex administration causes an increase in BP in all patients. The mean increase in BP amounted 20,06/11,6 ± 8,36/14,23 mmHg and was similar in all patients, regardless their initial value of BP. So our study demonstrates the need of individualized hypertension treatment with strict control of BP in hypertensive patients when corticosteroid therapy is indicated.

Arterial blood pressure measurements were obtained from 158 healthy Irish wolfhounds using the oscillometric technique to establish reference values for the breed. In contrast to other sight hounds, Irish wolfhounds have low arterial blood pressure. Mean systolic pressure for the group was 116.0 mm Hg. Mean diastolic pressure was 69.2 mm Hg, and the mean value for mean arterial pressure was 87.8 mm Hg. Blood pressure measurements were higher in older wolfhounds than in young dogs. There was no difference between systolic and mean arterial blood pressures in lateral recumbency compared to standing position. However, diastolic pressure was slightly lower when standing. Calm dogs had lower pressure than anxious wolfhounds. There was a significant interaction between the effects of age, gender, and mood on systolic, diastolic, and mean arterial blood pressure values.

Background: The aim of this study was evaluation of nocturnal dipping of blood pressure in ST-elevation myocardial infarction (STEMI) patients and determining the effect of dipping on outcomes at 12 months follow-up.Methods: This was an observational, single-centre, retrospective study that included STEMI patients, performed in a tertiary care hospital in India from November 2016 to October 2017. The primary endpoint of the study was the assessment of outcomes at 12 months.  The patients were divided into two groups on the basis of blood pressure dipping, i.e., patients with positive dipping were considered in group 1 and patients with negative dipping were considered in group 2.Results: Total 43 patients were included in the study. Group 1 consisted of 27 patients and Group 2 consisted of 16 patients. Mean 24 hr systolic blood pressure (SBP) and asleep SBP in Group 1 patients was 128.15±18.05 mmHg and 122.67±18.94 mmHg, respectively. Mean 24 hr diastolic (DBP) and asleep DBP in Group 1 patients was 78.07±10.73 mmHg and 73.41±12.35 mmHg, respectively. In the patients with non-dipping, mean 24 hr SBP and asleep SBP was 130.56±27.32 mmHg and 135.13±29.58 mmHg, respectively. Mean 24 hr DBP and asleep DBP was 76.00±15.40 mmHg and 79.69±17.05 mmHg, respectively. The mean percentage of asleep dipping of SBP was 5.7±6.7% in Group 1 and -4.6±6.82% in Group 2. Similarly, the mean percentage of asleep dipping of DBP was 7.6±9.0% in Group 1 and -6.3±9.1% in Group 2.Conclusions: In view of the results, it can be concluded that ambulatory blood pressure monitoring in patients with STEMI can provide a significant prognostication of the future events.
