ARTP01

Question 1

How do you calculate minimum spontaneous VT?

Answer 1

Use the IBW formula and then multiply by 5.

Question 2

Minimum value for minute ventilation

Answer 2

<5L/min or >10L/min

Question 3

***What is the main way to evaluate the effectiveness of bronchodilators

Answer 3

Peak flow meter (this is for sure on the test)

Question 4

Respirometers can measure what four things?

Answer 4

VE VT VC RSBI (we use a Wrights respirometer)

Question 5

What is the main difference between Respirometers and Barometer?

Answer 5

Respirometer measures VOLUME in Liters/mL, and the barometer measures PRESSURE in cmH2O

Question 6

Normal minute ventilation

Answer 6

5-10L/min

**Assesses ability to tolerate weaning from ventilator

Question 7

Minute Vent formula

Answer 7

VE= VT x RR

Question 8

If minute vent is over 10L/min what does it mean?

Answer 8

Means the patient is working too hard to breathe.

Question 9

What measurement evaluates if the patient is breathing deep enough

Answer 9

Tidal Volume

Obtained using IBW x 5= Minimum spontaneous TV

Question 10

What are the two ways to measure VC?

Answer 10

Via Wrights respirometer doing a FVC or SVC.

SVC- have them inhale all the way in and then slowly exhales into device until fully empty.

Question 11

What does VC measure?

Answer 11

Measures the patient’s inspiratory reserve volume and expiratory reserve volume. **Allows us to know how they will be able to ventilate under stress/ADLs

Question 12

Normal VC? minimum?

Answer 12

65-75ml/kg of IBW

Minimum acceptable is 10ml/kg

Question 13

Which lung volumes make up IC?

Answer 13

Resting tidal volume + Inspiratory reserve

Question 14

Which lung voumes make up your VC?

Answer 14

Inspiratory reserve/tidal volume/expiratory reserve

Question 15

What does IC measure?

Answer 15

Volume of air that you can maximally inhale from resting expiration

Question 16

A pressure manometer measures what?

Answer 16

It helps you obtain someones NIF MIP or MIF in cmH20

Question 17

What does it mean if you have a higher negative reading on the pressure monometer?

Answer 17

The more negative, the stronger the inspiratory muscles.

-70cmH20 is stronger than a reading of -30cmH20

Question 18

If you want to determine an appropriate treatment, what value would you want to look at?

Answer 18

IC (volume of air that can be maximally inspired from resting expiration)

Question 19

Normal value and minimum value of NIF

Answer 19

• 20 is minimum. >-80 is normal.

* *If they are at -20, the still might be weaned off vent but just much more comfortable.

Question 20

RSBI normal value

Answer 20

less than 105. If 106 or greater, they are not a good choice to start weaning
