Avoid hip flexion or bending the neck, as these can compress jugular veins and increase ICP. Ensure the cervical collar is not too tight if one is in place. This positioning optimizes cerebral perfusion pressure (CPP) by maximizing venous outflow without compromising arterial inflow.
Do not encourage coughing or deep breathing exercises during acute ICP elevation. These activities mimic the Valsalva maneuver, increasing intrathoracic pressure, reducing venous return from the brain, and causing a dangerous spike in ICP.
