Do you hyperventilate a head injury?
Hyperventilation lowers intracranial pressure (ICP) by the induction of cerebral vasoconstriction with a subsequent decrease in cerebral blood volume. The downside of hyperventilation, however, is that cerebral vasoconstriction may decrease cerebral blood flow to ischemic levels.
When should you hyperventilate a head injury?
Current Statewide Basic Life Support Adult and Pediatric Treatment Protocols stipulate that hyperventilation, at a rate of 20 breaths per minute in an adult and 25 breaths per minute in a child, should be employed in major trauma whenever a head injury is suspected, the patient is not alert, the arms and legs are …
Is hyperventilation bad for the brain?
Hyperventilation decreases the intracranial pressure and relaxes the brain. Hyperventilation increases neuronal excitability and seizure duration, which contribute to damaged brain metabolism. Hyperventilation also causes cerebrospinal fluid to alkalinize, pH to rise, and oxygen delivery to decrease.
Why do you hyperventilate a patient with ICP?
Hyperventilation is one known method of rapidly lowering ICP. Cerebral blood flow is largely dependent on PaCO2. Hyperventilation causes decreased PaCO2 which subsequently leads to arterial vasoconstriction thus lowering cerebral blood flow (CBF), cerebral blood volume, and ICP.
What is hyperventilating a symptom of?

Why is it bad to hyperventilate?
Can you pass out from hyperventilating?
Do you give oxygen to a hyperventilating patient?
Does hyperventilating let you go further underwater?
At what percentage does oxygen become toxic?
What is a reverse squeeze or block?
What happens if your oxygen concentrator is set too high?
Oxygen toxicity is lung damage that happens from breathing in too much extra (supplemental) oxygen. It’s also called oxygen poisoning. It can cause coughing and trouble breathing. In severe cases it can even cause death.
How Low Can oxygen level get before it is fatal?
An oxygen level below 88% can be dangerous for any period of time. An oxygen level below 85% warrants a trip to the hospital. Keep in mind that an oxygen level 80% and lower puts your vital organs in danger, so it is important to keep a blood oxygen level chart handy so you know what levels require immediate treatment.
