Variability in time delay between two models of pulse oximeters for deriving the photoplethysmographic signals.
Pulse oximetry is commonly used as an arterial blood oxygen saturation (SaO2) measure. However, its other serial output, the photoplethysmography (PPG) signal, is not as well studied. Raw PPG signals can be used to estimate cardiovascular measures like pulse transit time (PTT) and possibly heart rate (HR). These timing-related measurements are heavily dependent on the minimal variability in pha...
متن کاملPulse Rate Analysis from the Photoplethysmographic Signal for Turbulence Detection
In this paper we assessed the possibility of using the pulse rate (PR) extracted from the photoplethysmographic signal for turbulence detection as an alternative to the heart rate (HR). The study is based on analysis of the rhythm changes observed during 4131 ventricular premature beats of 27 subjects. Classical features for turbulence analysis, turbulence onset and turbulence slope were estima...
متن کاملPreliminary Design of Spacecraft Attitude Control with Pulse-Width Pulse-Frequency Modulator for Rest-to-Rest Maneuvers
In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...
متن کاملPuLSE-I: Deriving Instances from a Product Line Infrastructure
Reusing assets during application engineering promises to improve the efficiency of systems development. However, in order to benefit from reusable assets, application engineering processes must incorporate when and how to use the reusable assets during single system development. However, when and how to use a reusable asset depends on what types of reusable assets have been created. Product li...
متن کاملContour analysis of the photoplethysmographic pulse measured at the finger.
Analysis of the contour of the peripheral pulse to assess arterial properties was first described in the nineteenth century. With the recognition of the importance of arterial stiffness there has been a resurgence of interest in pulse wave analysis, particularly the analysis of the radial pressure pulse acquired using a tonometer. An alternative technique utilizes a volume pulse. This may conve...
