Increased Intracranial Pressure Nursing Pathophysiology NCLEX Symptoms (Cerebral Perfusion Pressure)

Increased intracranial pressure (ICP) nursing, pathophysiology, NCLEX, treatment, and symptoms NCLEX review.
Increased intracranial pressure occurs when the inside of the skull experiences increased pressure. This is a medical emergency!
How is ICP created? Intracranial pressure is the pressure created by the cerebrospinal fluid and brain tissue/blood within the skull. It can be measured in the lateral ventricles with an external ventricular drain (ventriculostomy).
What is a normal intracranial pressure (ICP)? 5-15 mmHg (greater than 20 mmHg…needs treatment)
Pathophysiology of increased intracranial pressure: The human skull is very hard and is limited on how much it can expand when something inside the skull experiences a change that leads to increased pressure exerted within the skull.
Inside the skull are three structures that can alter intracranial pressure: brain, cerebrospinal fluid (CSF), and blood.
The Monro-Kellie hypothesis deals with how ICP is affected by CSF, brain's blood, and tissue that works to maintain cerebral perfusion pressure (CPP). In a nutshell, this hypothesis says that when the volume of one of these structures increases than the others will have to decrease their volume to compensate for the increased intracranial pressure.
Intracranial pressure fluctuates and this depends on many factors like: the person’s body temperature, oxygenation status, especially CO2 and O2 levels, body position, arterial and venous pressure, anything that increases intra-abdominal or thoracic pressure (vomiting, bearing down).
Cerebral perfusion pressure is important when dealing with intracranial pressure. A normal CPP is 60-100 mmHg.
When CPP (pressure that pushes the blood to the brain) falls too low the brain is not perfused and brains tissue dies.
How is CPP calculated?
CPP= MAP - ICP (see video on how to calculate cerebral perfusion pressure)
Symptoms of increased intracranial pressure: mental status changes (EARLIEST), cushing's triad, vomiting, headache, decorticate or decerebrate posturing, optic and oculomotor nerve damage, abnormal doll's eye, seizures etc.
Nursing care for increased ICP includes monitoring and preventing further increases in intracranial pressure, administering drugs such as Mannitol, anticonvulsants, corticosteroids etc. See video for a mnemonic on the nursing interventions for increased ICP.

[@singingforthelordjesusviviane]

[@lobarita]

I studied your videos all through school. Now, I’m an ICU nurse (graduated may 2020) and I’m caring for my first patient with increased ICP. The first thing I did was come watch this video. My patient has all the signs you covered, very late stage. Thank you!!! You’re helping me treat patients in real time.

[@renaekelly2149]

I just wanted to say your videos helped me pass NCLEX. I took NCLEX on November 16th and passed on my first try!. I'm so excited to start my nursing career. I went to speak with the new class and told them about your videos and how you make it easy to understand the content. Thank you so much and I will continue to watch your videos!

[@riadepalmz]

When I had my accident, I fell down 13 oak stairs, I had to be intubated at pickup, was in a coma for approx. 6 weeks, and the doctor upon arrival had to drill a hole in my head to relieve the pressure. I basically was the equivalent of a 3 month old baby. I had to learn how to walk, talk and basically learn how to grow up again

[@vizon-aryproductions6191]

I suffer with this condition and i work at a casino , the flashing lights and sounds of skot machines , live events loud sounds have me in agony after work ... spinal taps help the best but when a spinal headaches i dont wish it upon my worse enemy its like getting constantly beaten in the head with an aluminum bat, even laying down and trying to move positions u feel like ur brain has been stabbed with a knife

Since we are in the midst of a pandemic, we are subjected to have our online learning class through zoom and google meet. As a student nurse, it is hard for me to strive in nursing school. I struggle right now in my medical surgical nursing which is the sole foundation of nurses in providing appropriate care to the patients. Thanks to your videos, I am now catching up with our daily lesson. Hoping to wear the RN title at the end of my name soon
