What occurs when pressure within the skull increases due to brain swelling?

When pressure within the skull increases due to brain swelling, a decrease in blood flow to the brain occurs as a physiological response. This condition is often referred to as increased intracranial pressure (ICP). As the pressure rises, it can compress blood vessels, restricting blood flow and thereby reducing the amount of oxygen and nutrients that reach the brain tissue.

When the brain is unable to receive adequate blood flow, critical functions may be compromised, leading to potential damage. In scenarios where the pressure continues to escalate, it can result in further neurological deficits or brain injury. Understanding the mechanics behind increased ICP is crucial for EMTs, as it underscores the importance of monitoring and managing head injuries effectively to prevent worsening conditions for patients.
