Cerebral shunts are commonly used to treat hydrocephalus, the swelling of the brain due to excess buildup of cerebrospinal fluid (CSF). If left unchecked, the cerebrospinal fluid can build up leading to an increase in intracranial pressure (ICP) which can lead to intracranial hematoma, cerebral edema, crushed brain tissue or herniation. The cerebral shunt can be used to alleviate or prevent these problems in patients who suffer from hydrocephalus or other related diseases.
Shunts can come in a variety of forms but most of them consist of a valve housing connected to a catheter, the end of which is usually placed in the peritoneal cavity. The main differences between shunts are usually in the materials used to construct them, the types of valve (if any) used, and whether the valve is programmable or not.
I need some help!
Can you help with these problems?
1. A 60-HP 230 volt shunt motor has a shunt field resistance of 38.3 ohms and an armature resistance of 0.04 ohm. If the resistance in the starter is 0.66 ohm, calculate the current input to the motor at the instant it is started. (Assume...
hi,
I'm currently learning about self-excited and separate shunt generators, and I'm having a hard time comprehending the residual magnetism.
i was just wondering if a generator have lost all of its residual magnetism, can it still build up an output voltage? can someone explain this to...
A galvonometer has a coil resitance of 460 ohms and a full scale deflection current of of 100^10*-6 A What shunt resistor is needed to convert this galv.. into an ammeter which has a full scale deflection current of 200 ^10*-3 A? What is the resitance of the ammeter when it is completed? What...
