When you plug your device into a charging socket or wall charger, the USB controller in your device talks to the USB controller attached to the socket/wall charger â or, if no controller is available, the device reads the voltage flowing across the four USB pins.
The volume of the ventricles is about 25 ml. CSF is produced at a rate of 0.2 - 0.7 ml per minute or 600-700 ml per day. The circulation of CSF is aided by the pulsations of the choroid plexus and by the motion of the cilia of ependymal cells.
For example, if a CSF had a WBC count of 700/uL, CSF/blood glucose ratio of 0.2, CSF Lactate of 32 mg/dL and a CSF protein of 42 mg/dL, then the overall likelihood ratio is 729, which is calculated by multiplying 15 x 18 x 3.0 x 0.9.otal CSF volume is 90-150 mL in adults and 10-60 ml in neonates. There is a constant turnover of about 14% of the volume per hour. About 300-500 mL of CSF are formed per 24 hours (0.35 mL per minute).
