On an automatic delineator for arterial blood pressure waveforms
Arterial blood pressure waveforms contain rich pathophysiological information; hence receive much attention in cardiovascular health monitoring. To assist computerized analysis, an automatic delineator was proposed for the fiducial points of arterial blood pressure waveforms, namely their onsets, systolic peaks and dicrotic notches. The presented delineator characterizes arterial blood pressure...
متن کاملNoninvasive haemodynamic monitoring using finger arterial pressure waveforms.
Haemodynamic monitoring may potentially lead to improved quality of care in haemodynamic compromised patients. However, the usefulness of invasive techniques using the pulmonary artery catheter is questioned. Noninvasive techniques which provide data on haemodynamics might provide a good alternative. New techniques have been developed in recent years to monitor cardiac output and other paramete...
متن کاملDoes the Pleth variability index indicate the respiratory-induced variation in the plethysmogram and arterial pressure waveforms?
BACKGROUND Respiratory variations in the pulse oximeter plethysmographic waveform amplitude (deltaPOP) are sensitive to changes in preload and can predict fluid responsiveness in mechanically ventilated patients. However, they cannot be easily calculated from a bedside monitor. Pleth variability index (PVI, Masimo Corp., Irvine, CA) is a new algorithm that automatically calculates deltaPOP. The...

متن کاملEffects of inspiratory flow waveforms on arterial blood gases and respiratory mechanics after open heart surgery.
The clinical usefulness of inspiratory flow pattern manipulation during mechanical ventilation remains unclear. The aim of this study was to investigate the effects of different inspiratory flow waveforms, i.e. constant, sinusoidal and decelerating, on arterial blood gases and respiratory mechanics, in mechanically ventilated patients. Eight patients recovering after open heart surgery for valv...
