Altered Retinal Hemodynamics and Mean Circulation Time in Spontaneously Hypertensive Rats.
Leskova W, Warar R, Harris NR. Leskova W, et al. Invest Ophthalmol Vis Sci. 2020 Aug 3;61(10):12. doi: 10.1167/iovs.61.10.12. Invest Ophthalmol Vis Sci. 2020. PMID: 32761138 Free PMC article.
Retinal vascular velocities were measured with the use of fluorescent microspheres, and diameters and mean circulation times were measured after the infusion of fluorescent dextran. ...Despite a tendency toward lower retinal blood flow rates, the mean circula …

Errors and Consequences of Inaccurate Estimation of Mean Blood Flow Velocity in Cerebral Arteries.
Czigler A, Fedriga M, Beqiri E, Lalou AD, Calviello LA, Cabeleira M, Toth P, Smielewski P, Czosnyka M. Czigler A, et al. Acta Neurochir Suppl. 2021;131:23-25. doi: 10.1007/978-3-030-59436-7_5. Acta Neurochir Suppl. 2021. PMID: 33839811
Many transcranial Doppler ultrasonography devices estimate the mean flow velocity (FVm) by using the traditional formula (FVsystolic + 2 FVdiastolic)/3 instead of a more accurate formula calculating it as the time integral of the current flow velocities divid …

Cerebral hemodynamics in preeclampsia and eclampsia.
Qureshi AI, Frankel MR, Ottenlips JR, Stern BJ. Qureshi AI, et al. Arch Neurol. 1996 Dec;53(12):1226-31. doi: 10.1001/archneur.1996.00550120034013. Arch Neurol. 1996. PMID: 8970450 Review.
RESULTS: Eclamptic patients (n = 3) had significantly higher mean flow velocities and lower average pulsatility indexes than did normotensive patients (n = 4) (average MCA-mean flow velocity, 165 vs 79 cm/s [P = .007]; average MCA pulsatility index, 0. …

Transcranial Doppler in cerebral vasospasm.
Newell DW, Winn HR. Newell DW, et al. Neurosurg Clin N Am. 1990 Apr;1(2):319-28. Neurosurg Clin N Am. 1990. PMID: 2136144 Review.
Normal mean velocity for the MCA is 62 +/- 12 cm/sec. Significant spasm on angiogram of the MCA corresponds to a mean velocity of 120 cm/sec. Mean velocities of the MCA of 200 cm/sec or greater indicate severe spasm and correlate with 50% …

Transcranial Doppler in hemoglobin SC disease.
Vieira C, de Oliveira CN, de Figueiredo LA, Santiago RP, Adanho CS, Santana SS, Burak CL, Lyra IM, Goncalves MS. Vieira C, et al. Pediatr Blood Cancer. 2017 May;64(5). doi: 10.1002/pbc.26342. Epub 2016 Dec 13. Pediatr Blood Cancer. 2017. PMID: 27957790
A total of 1,664 pediatric patients with SCD underwent TCD velocity screening, and the time-averaged maximum mean velocity (TAMM) was determined in the middle cerebral artery (MCA), anterior cerebral artery (ACA), and distal intracranial internal carotid arte …

Doppler-derived mean aortic flow velocity in children: an alternative to cardiac index.
Seear MD, D'Orsogna L, Sandor GG, de Souza E, Popov R. Seear MD, et al. Pediatr Cardiol. 1991 Oct;12(4):197-200. doi: 10.1007/BF02310565. Pediatr Cardiol. 1991. PMID: 1946006
Ascending aortic flow velocities were obtained by pulse Doppler and mean aortic velocities calculated. Mean aortic flow velocity was relatively constant for all ages at 28.4 +/- 4.8 cm/s. ...

The Laniakea supercluster of galaxies.
Tully RB, Courtois H, Hoffman Y, Pomarède D. Tully RB, et al. Nature. 2014 Sep 4;513(7516):71-3. doi: 10.1038/nature13674. Nature. 2014. PMID: 25186900
If the distance to each galaxy from Earth is directly measured, then the peculiar velocity can be derived from the subtraction of the mean cosmic expansion, the product of distance times the Hubble constant, from observed velocity. The peculiar velocity …

Second-trimester growth velocities in twin and singleton pregnancies.
Anderson JN, Deter RL, Datoc IA, Mack L, Gandhi M, Lee W, Blumenfeld YJ. Anderson JN, et al. Ultrasound Obstet Gynecol. 2023 Jan;61(1):33-39. doi: 10.1002/uog.26102. Ultrasound Obstet Gynecol. 2023. PMID: 36273412 Free article.
Mean growth velocities and variances were compared among the three groups. ...Only 1-2% of all MCDA and DCDA anatomical parameters had abnormal growth velocity scores outside the 95% reference range for singletons. There were no significant differences in …

Normal saccadic velocities.
Raab EL. Raab EL. J Pediatr Ophthalmol Strabismus. 1985 Jan-Feb;22(1):20-2. doi: 10.3928/0191-3913-19850101-07. J Pediatr Ophthalmol Strabismus. 1985. PMID: 3981377
Horizontal saccades of 20 degrees across the midline, with fixation by the recorded and by the non-recorded eye, were observed. Peak velocity determinations distributed normally and ranged from 281 to 541 (mean and SD = 393 +/- 50) degr/sec. Mean velocitie …

Establishment of relationship between mean and maximum velocities in narrow sewers.
Bonakdari H. Bonakdari H. J Environ Manage. 2012 Dec 30;113:474-80. doi: 10.1016/j.jenvman.2012.10.016. Epub 2012 Oct 27. J Environ Manage. 2012. PMID: 23107096
The maximum velocity in any channel cross section might be as important as the mean velocity. It is easier to measure the maximum velocity than the mean velocity, and many flow rate sensors measure maximum velocity and convert it t …
