Final answer:
To reduce cellular edema and decrease ICP, one should manage fluid and electrolyte balance, particularly sodium intake, correct underlying health issues, and use therapies like elevation and compression to assist in fluid drainage.
Step-by-step explanation:
To decrease intracranial pressure (ICP) by reducing cellular edema, it is important to address the balance of electrolytes and fluid in the body. Strategies include reducing sodium intake, which may help decrease sodium and water retention. Additionally, addressing underlying conditions that contribute to edema, such as congestive heart failure or liver disease, will also help reduce swelling due to fluid buildup. The aim is to restore normal osmotic balance, preventing water from excessively entering cells and causing cellular swelling. In cases where cellular edema is due to reduced osmotic pressure from low plasma protein levels, therapy may involve administration of albumin or other plasma expanders to increase colloid osmotic pressure. Furthermore, elevation of affected body parts and compression therapy can facilitate fluid drainage and reduce swelling.
