CHAPTER 29 ACUTE RESPIRATORY DISTRESS SYNDROME
QUESTIONS WITH DETAILED VERIFIED AND 100%
ACCURATE ANSWERS
A common development in many clinical settings and is a common
reason for admission to the ICU? Correct Answers Acute Hypoxemic
Respiratory Failure (AHRF)
Acute hypoxic respiratory failure (AHRF) occurs when? Correct
Answers Oxygen is unable to reach the blood in enough quantity to
allow function
Common causes for AHRF are ? Correct Answers Pulmonary Edema,
Infection, Pulmonary Embolus, and Airway Obstruction.
what is key component of normal lung function ? Correct Answers
Maintain a net flux of fluid through the lung without causing lung
edema or alveolar consolidation.
The walls of the alveoulus are seperated from capillary walls by?
Correct Answers The very thin lung interstitium, the close proximity to
the capillary wall
What does the interstitium do? Correct Answers It minimizes the
distance for gases to diffuse.
,The vascular and lung work together to maintain what? Correct Answers
Maintain a physiologic amount of fluid leakage and the alveoli are fluid-
free.
In a disease state what occurs? Correct Answers The rate of the leakage
of fluid into the lung can exceed the lungs capacity to clear the fluid.
what can excess fluid in the lungs cause? Correct Answers -Pulmonary
edema-abnormal lung function-gas exchange
How does the lung protect itself from excess fluid accumulation?
Correct Answers 1) Lymphatic drainage system
2) Intrathoracic pressure alterations
The lymphatic system? Correct Answers Removes excess fluid.
Intrathoracic pressure alterations Correct Answers Occurs with
respiration, force fluid into lymphatic system
Why do the backup mechanisms exist? Correct Answers 1) storing
additional fluid-2) protection against alveolar flooding
What is capable of storing twice the normal fluid content of the lungs?
Correct Answers Loose connective tissue surrounding the bronchioles
and bronchi
, What occurs once capacity is maximized and rate of fluid accumulation
exceeds the rate of lymphatic drainage? Correct Answers Fluid will start
to accumulate within the alveoli and alveoli then become flooded
ARDS Correct Answers acute respiratory distress syndrome
In pathologic disease states? Correct Answers The rate of fluid leakage
into the lung can exceed the lung's capacity to clear the fluid leading to
pulmonary edema with abnormal lung function and gas exchange.
The interstitial space of the lung is separated in to two compartments?
Correct Answers 1) The alveolar side- the space between the capillaries
and epithelial lining of the alveolus
2) the nonalveolar side.
What will happen once the rate of fluid accumulation exceeds that of the
lymphatic drainage system? Correct Answers 1. Fluid will start to
accumulate within the alveoli.
2. Alveoli then become flooded.
3. Pulmonary Edema Occurs!
What are the categories for the disease that causes pulmonary edema?
Correct Answers Hydrostatic and
non-hydrostatic
