ICP
ICP normal range is
5-15 mm Hg
Normal CPP is
60 to 100 mm Hg.
The most common early manifestations of ARDS that the nurse may see are
dyspnea and tachypnea.
When does a primary brain injury occur?
at the initial time of an injury.
Sustained increases in ICP result in brainstem compression and
brain herniation
How do you position a patient with a 1-sided lung problem
in a lateral or side-lying position "good lung down"
Secondary injury occurs due to
the resulting hypoxia, ischemia, hypotension, edema, or increased ICP that follows the primary injury.
How do you calculate CPP?
MAP − ICP = CPP
Which intervention is most likely to prevent or limit volutrauma in the patient with ARDS who is mechanically ventilated?
Use of low tidal volume ventilation
The cerebral perfusion pressure is
the pressure needed to ensure blood flow to the brain.
Types of cerebral edema include
vasogenic, cytotoxic and interstitial
What is the hallmark characteristic of ARDS?
Refractory hypoxemia
