INTRODUCTION: Shock, defined as a state of tissue hypoperfusion and the tissues reperfusion, is the main goal of management of shock. Increase in central venous saturation (CvSo2) and decrease in blood lactate level are useful in assessment of adequacy of tissue perfusion. Near-infrared spectroscopy is a noninvasive way to observe real-time changes in regional cerebral saturation and has been used in patients with different brain diseases. There is a small body of literature suggesting that cerebral regional oxygen saturation (CrSo2) monitoring added a value in assessment and management of intensive care unit (ICU) patients...

The description of blood pressure (BP) curve has evolved to include several noninvasively determined parameters, such as aortic stiffness, BP variability, wave reflections, and pulse pressure amplification. These techniques are likely to improve the efficacy of assessing pulsatile arterial hemodynamics and changes in arterial stiffness. The goal for future antihypertensive treatments should not only reduce steady BP, but also control pulsatile pressure and modify the stiffness gradient between central and peripheral arteries, which is frequently elevated...

Background. Endothelial function is viewed as a barometer of cardiovascular health and plays a central role in vascular reactivity. Several studies showed digital thermal monitoring (DTM) as a simple noninvasive method to measure vascular reactivity that is correlated with atherosclerosis risk factors and coronary artery disease. Objectives. To further evaluate the relations between patient characteristics and DTM indices in a large patient registry. Methods. DTM measures were correlated with age, sex, heart rate, and systolic and diastolic blood pressure in 6084 patients from 18 clinics...

Central Systolic Blood Pressure is lower than brachial artery blood Pressure due to reflected waves and greater augmentation at the periphery. The relationship is not consistent during life and alters with aging of the blood vessels. Increasing stiffness means that a greater component of the reflected waves returns to the central aorta during systolic contraction causing more amplification and a higher systolic blood pressure. Diastolic blood pressure on the other hand is always higher in the aorta than at the periphery allowing blood flow...

INTRODUCTION: Gestational diabetes mellitus (GDM) is an indicator of future cardiovascular disease. We investigated if sensitive biomarkers of increased cardiovascular risk differ between women with and without a history of GDM few years after pregnancy, and whether obesity affects the results. MATERIAL AND METHODS: We studied two cohorts - 120 women with a history of GDM and 120 controls, on average 3.7 years after delivery. Circulating concentrations of oxidized low-density lipoprotein (oxLDL) were determined by ELISA...

We hypothesized that increased aortic forward pressure wave amplitude (Pf), which is determined by characteristic impedance (Zc) in the proximal aorta, is the primary hemodynamic determinant of obesity-associated higher left ventricular (LV) mass in adolescents. Aortic pulsatile hemodynamics were measured noninvasively in 60 healthy adolescents (age 14-19 years; 42% male; 50% black) by sequential recordings of pulse waveforms via tonometry, brachial blood pressure, and pulsed Doppler and diameter of the LV outflow tract using 2-dimensional echocardiography...

Vital organs are exposed to the central rather than the brachial blood pressure. To date, central blood pressure can be assessed noninvasively through the use of several devices. In this review, we critically discuss the clinical relevance of central blood pressure assessment. Considerable evidence suggests that central blood pressure is a better predictor of end-organ damage than brachial blood pressure. However, there is still uncertainty concerning the value of central pressure for predicting cardiovascular outcomes, as the existing studies are underpowered to address this issue...

BACKGROUND: Regular physical activity is known to reduce arterial pressure (BP). In a previous investigation, we could prove that even a single bout of moderate-intensity continuous exercise (MICE) causes a prolonged reduction in BP. Whether high-intensity interval training (HIIT) has a favourable influence on BP, and therefore may be followed subjects and methods by a prolonged BP reduction, should be examined on the basis of blood pressure response after exercise and during a subsequent stress test...

The central aortic blood pressure (cBP) waveform, which is different to that of peripheral locations, is a clinically important parameter for assessing cardiovascular function, however the gold standard for measuring cBP involves invasive catheter-based techniques. The difficulties associated with invasive measurements have given rise to the development of a variety of noninvasive methods. An increasingly applied method for the noninvasive derivation of cBP involves the application of transfer function (TF) techniques to a non-invasively measured radial blood pressure (BP) waveform...

OBJECTIVE: The effects of seasonality on blood pressure (BP) and cardiovascular events are well established. However, the influence of seasonality and other environmental factors such as air pollutants on arterial stiffness, a key parameter for cardiovascular risk stratification in hypertensive patients, has never been analyzed. This cross-sectional study aimed at investigating whether seasonality (daily number of hours of light) and acute variations in outdoor temperature and air pollutants may affect carotid-femoral pulse wave velocity (PWV)...

Central blood pressure (BP) can be assessed noninvasively based on radial tonometry and may potentially be a better predictor of clinical outcome than brachial BP. However, the validity of noninvasively obtained estimates has never been examined in patients with chronic kidney disease (CKD). Here we compared invasive aortic systolic BP (SBP) with estimated central SBP obtained by radial artery tonometry and examined the influence of renal function and arterial stiffness on this relationship. We evaluated 83 patients with stage 3 to 5 CKD (mean estimated glomerular filtration rate [eGFR] 30 ml/min/1...

BACKGROUND: New techniques that measure central blood pressure (BP) using an upper arm cuff-based approach require performance assessment. The aim of this study was to compare a cuff-based device (CuffCBP) to estimate central BP indices (systolic BP (SBP), diastolic BP (DBP), pulse pressure (PP), augmentation pressure (AP), augmentation index (AIx)) with noninvasive radial tonometry (TonCBP). METHODS: Consecutive CuffCBP (SphygmoCor Xcel) and TonCBP (SphygmoCor 8...

Hypoperfusion is the most common event preceding the onset of multiple organ dysfunction syndrome during trauma resuscitation. Detecting subtle changes in perfusion is crucial to ensure adequate tissue oxygenation and perfusion. Traditional methods of detecting physiological changes include measurements of blood pressure, heart rate, urine output, serum levels of lactate, mixed venous oxygen saturation, and central venous oxygen saturation. Continuous noninvasive monitoring of tissue oxygen saturation in muscle has the potential to indicate severity of shock, detect occult hypoperfusion, guide resuscitation, and be predictive of the need for interventions to prevent multiple organ dysfunction syndrome...
