This is a pilot study to investigate whether patients at advanced age are fluid responders via a reversible fluid challenge, the passive leg raise test. This will be measured with a non-invasive cardiac output monitor, the LiDCO (LiDCO Hemodynamic monitoring) .
The intervention is as simple as a passive leg raise with measurement of effect on Stroke volume.
Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
Passive leg raise

Difficulties in the accurate assessment of intravascular volume in critically ill patients are frequently encountered. In addition to clinical evaluation, bedside echocardiographic measure...
Purpose: Fluid responsiveness in a context of circulatory failure can be predicted by different way. Dynamic criteria such as pulse pressure variation, stroke volume variation during an ...
To overcome the limited accuracy of functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) during spontaneous breathing, a Passive Leg Raising (...
Evaluation of electrical impedance tomography to non-invasively monitor stroke volume when compared to reference measurements performed via right heart thermodilution
Rapid volume expansion using repeated intravenous fluid boluses is a very common intervention performed in the intensive care unit (ICU) in the early days of resuscitation of patients with...
Hypovolemia decreases preload and cardiac stroke volume. Cardiac stroke volume (SV) and its variability (cardiac stroke volume variability, SVV) have been proposed as clinical tools for detection of a...
The aim of this study was to evaluate the potential for shear wave elastography (SWE) to measure passive biceps brachii individual muscle stiffness as a musculoskeletal manifestation of chronic stroke...
Quantification of shunt volume is important for ventricular septal defects (VSDs). The aim of the in vitro study described here was to test the feasibility of using real-time 3-D color Doppler echoca...
We aim to analyze the impact of annual hospital volume on outcomes of endovascular mechanical thrombectomy (EMT) for acute ischemic stroke (AIS). In the recent past, increasing number of hospitals are...
A new computer model for systolic pulse waves within the cardiovascular system is presented. The emphasis was made on blood stroke volume (BS). The new waveform for pulse wave demands the re-computing...
The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
The amount of BLOOD pumped out of the HEART per beat not to be confused with cardiac output (volume/time).
A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities.
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
