Thermodilution cardiac output (L/minute), mixed venous oxygen saturation (SvO2) (Vigilance®; Edwards Lifesciences LLC, Irvine, CA, USA), and carotid and femoral artery blood flows (TS 420 double-channel flowmeters, Transonic Systems Inc).
The primary element of the Coriolis flowmeter is a measuring tube conveying fluid.
MBF was measured in gastric, colon and jejunal mucosa, jejunal muscularis, the pancreas, the liver and the kidney using a multi-channel Laser Doppler flowmeter.
Microcirculatory blood flow was monitored continuously in the mucosa and the muscularis of the jejunum using a multi-channel laser Doppler flowmeter system (Oxford Optronix).
ANESTHESIA MACHINE CHECK (HIGHLIGHTS ONLY – SEE FULL CHECKLIST): Oxygen Line Pressure, Oxygen Flowmeter, Nitrous Line Pressure, Nitrous Flowmeter, Oxygen Tank Check, Check for Leaks, Vaporizer Check, Check Ventilator.
Superior mesenteric and left renal blood flows were measured by an ultrasonic flowmeter (One Channel Perivascular Flowmeter, Transonics Systems Inc., Ithaca, NY, USA) and normalized to the organ weights.
Regional blood flow in the SMA, the celiac trunk, and the hepatic artery was continuously measured throughout the experiments with ultrasonic transit time flowmetry (mL per minute) using two double-channel HT 206 flowmeters (Transonic Systems).
To continuously monitor systemic blood pressure, a 24-gauge angiocatheter was introduced into the carotid artery and connected to a pressure channel of the laser Doppler flowmeter (Model BLF21D, Transonic Systems, Inc., Ithaca, NY).
Laser Doppler flowmeter (LDF) (DRT4 dual channel, Moor Instruments Ltd ,Axminster, UK) was used to monitor regional cerebral blood flow (rCBF) before and at different time points after MCAO.
We may use the same idea of the particle sensing, but with two obstacles in the flow channel, to create a cross-correlation velocity flowmeter.
