10 Questions
What effect does pressure on the frontal lobes or deep midline structures have on respiratory patterns?
It leads to Cheyne-Stokes respirations.
Why is coughing discouraged in patients with poor oxygenation?
It can lead to an increase in intracranial pressure (ICP).
How does pressure in the midbrain affect respiration?
It causes hyperventilation.
How is PaCO2 usually maintained in patients undergoing hyperventilation therapy?
Less than 30 mm Hg
What is a controversial therapy in traumatic brain injury used to reduce intracranial pressure (ICP)?
Hyperventilation therapy
What effect does hyperventilation therapy have on cerebral blood volume?
Decreases cerebral blood volume
Why are the lung fields auscultated every 8 hours in patients?
To determine the presence of adventitious sounds or areas of congestion
How does elevating the head of the bed help in patients with brain injury?
Aids in clearing secretions and improves venous drainage of the brain
What happens when the lower portion of the brainstem is involved in a patient's condition?
Respirations become irregular and eventually cease.
What type of monitoring is beneficial for patients on hyperventilation therapy?
Multimodality monitoring to assess overall impact on brain perfusion.
