Ch.1&3 Pilbeams HW

Question 1

The highest pressure recorded at the end of inspiration is called ________________ or __________________.

Answer 1

Peak pressure or peak inspiratory pressure (PIP)

Question 2

The pressure at which expiration ends is called _____________________.

Answer 2

Baseline pressure

Question 3

When end expiratory pressure is above atmospheric pressure, this is called ________________.

Answer 3

PEEP

Question 4

The pressure required to overcome the elastic recoil of the lungs is known as ________________ and is measured on a mechanically ventilated patient by _________________________.

Answer 4

Pplat; selecting an inspiratory pause or inflation hold maneuver

Question 5

What are the two types of forces that oppose inflation of the lungs?

Answer 5

Elastic or frictional forces

Question 6

List two factors that determine the way the inspiratory volume is delivered.

Answer 6

• The structural design of the vent
• The mode set by the clinician

Question 7

List two synonyms for pressure controlled ventilation.

Answer 7

• Pressure targeted ventilation
• Pressure ventilation

Question 8

List two synonyms for volume-controlled ventilation.

Answer 8

• Volume targeted ventilation
• Volume ventilation

Question 9

During pressure controlled breaths, the compliance and resistance of a patient’s lungs change. What happens to volume and flow?

Answer 9

The volume and flow waveforms will vary

Question 10

If during volume controlled breaths the patient’s lung compliance decreases, what will happen to the peak inspiratory pressure?

Answer 10

It will increase because the pressure waveform varies with changes in lung characteristics
