Clinical application of mechanical ventilation
EXAM QUESTIONS WITH CORRECT ANSWERS
A ventilator mode is determined by what factors? - CORRECT ANSWER✅✅✅1. targeted controlled
variables (pressure, volume, or both)
2. what type of breath is available (M, A, PS, S)
Actual baseline includes - CORRECT ANSWER✅✅✅autoPEEP
Actual PEEP - CORRECT ANSWER✅✅✅PIP - Total PEEP = PG
Actual pressure gradient will be decreased if - CORRECT ANSWER✅✅✅autoPEEP is present
decrease PG = decrease Vt
Acute ventilator failure (not breathing enough - one ABG) CRITERIA: - CORRECT
ANSWER✅✅✅CO2>55 with a pH <7.25
ACV trigger variable for assist - CORRECT ANSWER✅✅✅pt triggered when they meet a flow or
pressure sensitivity setting
ACV trigger variable for mandatory - CORRECT ANSWER✅✅✅time triggered based on set RR
Advantage of targeted volume control variable? - CORRECT ANSWER✅✅✅Vt is guaranteed
Advantages of pressure ventilation? - CORRECT ANSWER✅✅✅flow will meet pts demand
Advantages of pressure ventilation? Can control - CORRECT ANSWER✅✅✅pressure to reduce risk of
alveolar overdistention, & volutrauma
, Advantages of pressure ventilation? Descending - CORRECT ANSWER✅✅✅flow pattern promotes
laminar flow which will decrease resistance deadspace ventilation & allow for more equal gas
distribution
Advantages of VTPC: ____ wll be delivered even with - CORRECT ANSWER✅✅✅Vt even with
changes in lung compliance & resistance as long as: HPL is not met
Advantages of VTPC: A _______ flow pattern & ______ flow is used - CORRECT
ANSWER✅✅✅decelerating flow pattern & variable flow is used improving gas distribution &
meeting pts inspiratory demand.
Advantages of VTPC: A _______ pressure pattern is used to increase? - CORRECT
ANSWER✅✅✅square; MAWP (oxygenation)
Advantages of VTPC: Lowest pressure is used to deliver - CORRECT ANSWER✅✅✅target Vt; if HPL is
met the breath is not terminated pt has some control over ventilation & it can be guaranteed
Apnea - CORRECT ANSWER✅✅✅observation
Assist control (AC) or VTPC: Types of breaths offered - CORRECT ANSWER✅✅✅machine or assist
Baseline PEEP - CORRECT ANSWER✅✅✅PIP - Set PEEP= PG
Characteristics of VTPC: Operator sets a ___________ to be delivered during a ________ or ________
breath. The ventilator starts out at __________ & then automatically, the breath by breath, adapts the
_______________ level in small increments (1-3cmH20) according to the CL and Raw of the lungs to
deliver the ________ and/or ____ volume with the lowest possible pressure needed. And weans
pressure in same way at as Cl and Raw improves; Tidal volume is _______________ - CORRECT
ANSWER✅✅✅target Vt
mandatory or assisted
10 cmh20
inspiratory pressure control
