Expérimental: CVInsight (TM)
Patient will be placed on a tilt table and pulse oximetry (Nonin Medical)and blood pressure will be measured at different table positions (different angles).
A hemodynamic monitor called CVInsight(TM) will be used to monitor the pulse oximeter readings.

Patient will be placed on a tilt table and pulse oximetry (Nonin Medical) and blood pressure will be measured at different table positions (different angles).
Four positions will be explored.
A hemodynamic monitor called CVInsight(TM) will be used to monitor the pulse oximeter readings.

Description de la mesure |
Délai |
|---|---|---|
|
Pulse Rate
Délai: Average pulse rate from baseline to 30 minutes
|
Continuous change of pulse rate from baseline through the end of the study will be followed.
Changes in pulse rate will be plotted against the four tilt table positions.
Four positions will be explored, Mounting position, baseline, passive leg raise (cardiac preload dependent) and orthostasis head raise (cardiac afterload dependent).
Patients go from mounting position, to baseline, to the corresponding position (passive leg raise or orthostasis head raise) and back to baseline.
The assessment will take 30 minutes.
From the graph, average pulse rate is calculated.

Average pulse rate from baseline to 30 minutes

Pulse Strength
Délai: Average pulse strength from baseline to 30 minutes
|
Continuous change of pulse strength from baseline through the end of the study.
Pulse strength is measured as volts by the system.
Changes in pulse strength will be plotted against the four tilt table positions.
Four positions will be explored, Mounting position, baseline, passive leg raise (cardiac preload dependent) and orthostasis head raise (cardiac afterload dependent).
Patients go from mounting position, to baseline, to the corresponding position (passive leg raise or orthostasis head raise) and back to baseline.
The assessment will take 30 minutes.
Cardiac function curves will be constructed with the data collected and average pulse strength from baseline to 30 minutes will be reported.
