Assessment of pulse transit time to indicate cardiovascular changes during obstetric spinal anaesthesia.
BACKGROUND Pulse transit time (PTT) measurement may provide rapidly available beat-to-beat cardiovascular information when conditions change quickly and routine invasive arterial pressure measurement is not justified, for example during obstetric spinal anaesthesia. Method. We obtained ethics approval for an observational study of PTT during the onset of spinal anaesthesia in patients having el...

متن کاملAn Assessment of Pulse Transit Time For Detecting Heavy Blood Loss During Surgical Operation
The main contribution of this paper is the use of non-invasive measurements such as electrocardiogram (ECG) and photoplethysmographic (PPG) pulse oximetry waveforms to develop a new physiological signal analysis technique for detecting blood loss during surgical operation. Urological surgery cases were considered as the control group due to its generality, and cardiac surgery as experimental gr...
متن کاملPulse transit time and blood pressure during cardiopulmonary exercise tests.
Pulse transit time (PTT), the interval between ventricular electrical activity and peripheral pulse wave, is assumed to be a surrogate marker for blood pressure (BP) changes. The objective of this study was to analyze PTT and its relation to BP during cardiopulmonary exercise tests (CPET). In 20 patients (mean age 51+/-18.4 years), ECG and finger-photoplethysmography were continuously recorded ...
