Exercise treadmill testing (ETT) is a well-established procedure for the diagnosis, prognosis and functional assessment of patients with suspected cardiovascular disease. The use of handrail support during ETT is often discouraged as this has been demonstrated to overestimate functional capacity. It is unknown if this increase in functional capacity translates to an increase in cardiac workload. The aim of this study was to investigate if the use of handrail support during maximal ETT produces an increase in cardiac workload when compared to no handrail support.

Name: Physiological measurement
To identify, in patients with peripheral artery disease and intermittent claudication (IC), the reproducibility of heart rate (HR), blood pressure (BP), rate pressure product (RPP), heart rate variabi...
Cardiovascular health declines with age, increasing the risk of hypertension and elevated heart rate in middle and old age. Here, we used multivariate techniques to investigate the associations betwee...
Endotracheal tubes used for neonates are not as resistant to breathing as originally anticipated; therefore, spontaneous breathing trials (SBTs) with continuous positive airway pressure (CPAP), withou...
Standard bi-level noninvasive ventilation with fixed-level pressure support (PS) delivery may not maintain ventilation during the changes in pulmonary mechanics that occur throughout day and night, so...
Optimizing pressure support ventilation (PSV) can improve patient-ventilator interaction. We conducted a two-center, randomized cross-over study to determine whether automated PSV lowers asynchrony ra...
The purpose of this study is to determine whether wheelchair handrail compensator plus rehabilitation training could do better than ordinary wheelchair plus rehabilitation training in reli...
Dexmedetomidine, selective alfa2 receptors agonist produces sympatholysis. As a result heart rate decreases. With low doses blood pressure also decreases, with higher dosing - systematic v...
Collapsibility (CI-IVC), distensibility (dIVC) and delta (ΔIVC) indices, which are dynamic measures of inferior vena cava (IVC) diameter, are used to assess the intravascular volume statu...
The aim of this study is to evaluate the ventilator settings advice given by the BEACON care system in fitting with best level of support in patient under mechanical ventilation in Pressur...
Individuals with IBD are at risk for nutrient deficiencies. This prospective, non-randomized, open-label study will assess the effect of a nutrition support product on nutritional status i...
Blood pressure levels that are between normotension and hypertension. Individuals with prehypertension are at a higher risk for developing cardiovascular diseases. Generally, prehypertension is defined as SYSTOLIC PRESSURE of 131-139 mm Hg and/or DIASTOLIC PRESSURE of 81-89 when the optimal is 120/80 mm Hg. For diabetics and other metabolism diseases the prehypertension is around 110-129/70-79 mm Hg.
The signs of life that may be monitored or measured, namely pulse rate, respiratory rate, body temperature, and blood pressure.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
Pathological elevation of intra-abdominal pressure (>12 mm Hg). It may develop as a result of SEPSIS; PANCREATITIS; capillary leaks, burns, or surgery. When the pressure is higher than 20 mm Hg, often with end-organ dysfunction, it is referred to as abdominal compartment syndrome.
The tendency of a gas or solute to pass from a point of higher pressure or concentration to a point of lower pressure or concentration and to distribute itself throughout the available space. Diffusion, especially FACILITATED DIFFUSION, is a major mechanism of BIOLOGICAL TRANSPORT.
