Ch. 17 Flashcards
Describe the primary goal of mechanical ventilation & skills required to reverse respiratory failure?
To reduce WOB by providing adequate d gas exchange with minimal damage to lung tissue (barotrauma) and/or interference with the circulatory system.
What is PIP?
A limit variable that will not allow the delivered breath to result in a pressure greater than the set pip? Determine by the delivered Vt and is changed as needed to alter ventilation. Vent parameters that affect PIP are Vt, Ve, and Ti.
What is PEEP?
Positive pressure maintained in the patients airway and throughout the vent circuit during the expiratory phase of ventilation. Determined by end exhalation. Vent parameters that determine PEEP are Vt,Ve, RR, and PIP.
What is frequency (rate)?
What is I- Time?
What is MAP?
What is tidal volume?
What is minute ventilation?
What is dead space?
What is alveolar ventilation?
What is opening pressure?
What is driving pressure?
What is FRC?
What is diffusion time?
What is flow rate?
