PEEP Flashcards
(10 cards)
What does PEEP stand for?
Positive End-Expiratory Pressure
PEEP is a critical concept in mechanical ventilation.
What is the definition of PEEP?
The pressure applied by the ventilator at the end of expiration to keep alveoli open.
What are the primary purposes of PEEP?
Helps prevent alveolar collapse, improves gas exchange, and increases oxygenation.
What is the typical range for setting PEEP?
Usually set between 5–15 cm H₂O.
How is PEEP titrated?
Based on the patient’s oxygen saturation (SpO₂) and overall clinical condition.
What hemodynamic effect does PEEP have on the heart?
It can reduce venous return to the heart, leading to decreased cardiac output and hypotension.
What should be monitored closely after changes in PEEP?
Blood pressure.
What signs should nurses watch for after adjusting PEEP?
Signs of reduced perfusion or hemodynamic instability.
True or False: PEEP can help improve oxygenation.
True.
Fill in the blank: PEEP is typically set between _____ cm H₂O.
5–15
