RT Ch. 3 Mechanics Practice Quiz-F

88. When there is low compliance, the plateau pressure will be

high

95. A risk of Auto PEEP is trapped air and pressure due to inadequate expiratory time

True

95. Which is NOT a result of inadequate expiratory time due to Auto PEEP?

Increased compliance

73. Barotrauma can lead to pneumothorax and emphysema

True

93. WOB is equal to Force multiplied by

distance

93. Elevated WOB causes strengthening of respiratory muscles and increases energy.

False

88. When there is high compliance, the plateau pressure will be

low

73. Patients at higher risk of barotrauma include all of the following EXCEPT

Diabetes

94. Emphysema causes all of the following EXCEPT

decreased expiratory time

87. When there is low compliance, the peak pressure will be

high

93. Increased Tidal Volume has what effect on recoil force?

Increases it

94. Pulmonary fibrosis causes

increased respiration rate

78. The Plateau pressure equals the Tidal volume divided by

Compliance

73. Barotrauma= rupture of alveoli from excess peak airway pressure by a mechanical ventilator

True

93. Increased respiratory rate increases air flow, but also increases

friction

87. The lungs are "stiff" and have a higher than normal level of elastic recoil when there is

A low lung compliance

72. Represents the elastic recoil of lung-thorax.

Plateau pressure

93. WOB is the work required to overcome all the following EXCEPT

high compliance

87. There is low compliance in patients with ARDS or fibrotic lung disease

True

72. The mechanical respirator pauses for a second after delivering a breath

Plateau pressure
