Ophthalmic artery Doppler waveform in the newborn.
BACKGROUND The ophthalmic artery Doppler waveform (OADW) is thought to correlate with severity of systemic atherosclerosis. The goal of the present study was to evaluate risk of cardiovascular disease (CVD) in newborns small for gestational age (SGA) and appropriate for gestational age (AGA). METHODS AND RESULTS A total of 15 SGA and 26 AGA newborns were enrolled in the study. OADW was compar...
متن کاملOphthalmic artery Doppler waveform changes associated with increased damage in glaucoma patients.
PURPOSE To characterize Doppler waveform variables (early systolic acceleration [ESA] and systolic/diastolic mean velocity ratios [Sm/Dm]) of the Ophthalmic Artery (OA) by color Doppler imaging (CDI) in eyes with primary open-angle glaucoma (POAG). METHODS Analysis of CDI examinations of the retrobulbar circulation of patients with POAG (n = 102), normal tension glaucoma (NTG, n = 89), and he...
متن کاملComputerized Pulmonary Artery Catheter Waveform Interpretation
The pulmonary artery catheter (PAC) has been used for decades in the diagnosis and treatment of critically ill patients, but knowledge of PAC waveform interpretation remains inadequate among physicians and nurses. Inspired by the relative success of EKG interpretation programs, this study investigates the feasibility of computerized PAC waveform interpretation. Clinician-provided contextual dat...
متن کاملPulse Doppler Analysis in External Ophthalmic and the Long Ciliary Ophthalmic Arteries in the Cat
Objective- Analysis of the PSV (peak systolic velocity), EDV (end diastolic velocity) and RI (Resistant Index) in external ophthalmic and the long ciliary ophthalmic arteries in the cat by pulse Doppler. Design- Descriptive study Animals- 12 short haired “Tomcats” weighted about 3.9± 0.9 Kg no e general and optic disease in clinical, paraclinical and ophthalmoscopic examinations. Pr...
متن کاملThe Doppler velocity waveform.
Figure 1. Spectral analysis and the Doppler display. The fast Fourier transform (FFT) separates the Doppler signal into its component Doppler-shift frequencies and determines the amplitude at each frequency. Most ultrasound machines calculate Doppler-shifted frequencies over 5 msec increments and convert this to velocity information. These velocities are then displayed in a bin whose brightness...
