1a. Introducing Minute Ventilation

Question 1

“Pediatrics receive ______ and adults receive ______.”

Answer 1

Peds: Pressure
Adults: Volume

Question 2

What is considered the maximum pressure limit before barotrauma begins in the adult patient?

Answer 2

30 mmH2O

Question 3

Which mode allows for specific minute ventilation (VE?)

Answer 3

Volume ventilation

Question 4

Which mode allows for driving of EtCO2/pH toward a target.

Answer 4

Volume ventilation

Question 5

Which mode is considered best for pediatric patients?

Answer 5

Pressure (“Peds get pressure, adults get volume.”)

Question 6

Which mode requires healthy, compliant lungs?

Answer 6

Volume ventilation

Question 7

This mode stops filling the lungs when a certain pressure is reached.

Answer 7

Pressure ventilation

Question 8

This mode can prevent dangerously high pressures from occurring with mechanical ventilation.

Answer 8

Pressure mode. The PPlateau (or “max pressure”) is set on the vent

Question 9

What is the abbreviation for minute ventilation?

Answer 9

VE

Question 10

What is the formula for minute ventilation?

Answer 10

VE = RR x VT
(RR = respiratory rate; VT = tidal volume)

Question 11

A patient has a RR of 12 and VT of 450 cc. What is their VE?

Answer 11

VE = 12(450) = 5400/1000 = 5.4 L/min

Question 12

Changing VE is a key component to regulating _____.

Answer 12

EtCO2/pH
