Noninvasive Alternatives for Mechanical Ventilation

Question 1

How can the combination of positive pressure ventilation and artificial airways negatively affect a patient?

Answer 1

it places the patient at risk for multiple complications and significantly increases patient morbidity and mortality

Question 2

In what conditions would noninvasive ventilatory methods be less likely to be effective?

Answer 2

pneumonia or ARDS

Question 3

What are two noninvasive alternatives to invasive ventilation?

Answer 3

noninvasive intermittent positive pressure ventilation and continuous positive airway pressure

Question 4

What type of ventilation is seen when the ventilator emits pressurized air or “breaths” at a prescribed interval?

Answer 4

noninvasive intermittent positive pressure ventilation

Question 5

What are the two most common types of interfaces used with noninvasive intermittent positive pressure ventilation?

Answer 5

oronasal and nasal masks

Question 6

Where should skin integrity be checked most frequently when a patient is on NIPPV

Answer 6

bridge of the nose and cheeks

Question 7

How many limbs are seen in a ventilator circuit?

Answer 7

2

Question 8

What is the purpose of the expiratory limb of a ventilator?

Answer 8

prevent the patient from rebreathing CO2

Question 9

When would a patient have a smaller ventilator for their home setting?

Answer 9

if the patient has chronic respiratory failure

Question 10

What kind of device has a single limb and provides positive pressure support to the patient throughout the breathing cycle?

Answer 10

BiPAP
