VENT SETTINGS

Question 1

Volume Control Ventilation

Answer 1

A Ventilator Mode where each Breath Delivers a SET Tidal Volume Regardless of Pressure, which lets you PRECISELY APPLY Apply LUNG-PROTECTIVE Tidal Volumes
(e.g., ~6 mL/kg Ideal Body Weight) as Recommended after ROSC.

Question 2

IDEAL BODY WEIGHT

Answer 2

HEIGHT & SEX

A Calculated Weight Based MAINLY on Height (and Sex),
NOT Actual Body Mass.

IBW is Used to SET Tidal Volume so you don’t OVER-VENTILATE Obese Patients;
- a 6-foot male = 77–78 kg.

Question 3

Post–ROSC

Answer 3

The Period after ROSC following Cardiac Arrest; During this Phase,
CAREFUL CONTROL of Ventilation
(Normal EtCO₂ and AVOIDANCE of HyperOxia/HyperVentilation) is
CRITICAL to Protect the
BRAIN & Other ORGANS.

Question 4

LUNG-PROTECTIVE VENTILATION

Answer 4

Ventilation Strategy Using
- Relatively LOW Tidal Volumes
(~6 mL/kg ideal body weight),
- Appropriate Rates &
- Moderate PEEP
TO PREVENT
- Ventilator-Induced LUNG INJURY &
- AVOID EXCESSIVE Pressures or Volumes, Especially IMPORTANT
After ROSC or in At-RISK Lungs.

Question 5

TIDAL VOLUME

Answer 5

The Amount of AIR DELIVERED to the Pt With EACH BREATH,
Usually Measured in mL’s

ON EXAMS, Choose a Tidal Volume Calculated from IBW (around 6 mL/kg for LUNG-PROTECTIVE Ventilation)
RATHER Than Actual Weight.

Question 6

PRESSURE CONTROL MODE

Answer 6

A VENT MODE that Sets
- INSPIRATORY PRESSURE and
- Delivered TIDAL VOLUME Varies;
IF Pressure is Set TOO HIGH
(e.g., 30 cm H₂O),
It May Give VERY LARGE TIDAL VOLUMES & VIOLATE LUNG-PROTECTIVE Principles.
