Ch. 7 Flashcards
What is another name for RDS?
Hyaline membrane disease
What is the etiology of RDS?
A deficiency of surfactant production by alveolar type 2 cells.
What is the main contributor of RDS?
Prematurity of the pulmonary system or genetic problems with lung development.
What are the risk factors of RDS?
What are other causes of RDS?
• Overall immaturity of other organ systems contributed to its development.
• The immaturity of terminal air sacs and associated vasculature result in poor gas exchange across the alveolar capillary membrane.
• Immaturity if the chest wall form non-ossified bones allowing little stability.
_______ is also common in premature neonate due to the immaturity of the CNS system.
Apnea
What are some clinical signs of RDS?
• RR > 60bpm
• Grunting
• Retractions
• Increased FRC
• Greater negative pressure (due to the stiffening of the lungs to open collapsed alveoli)
• Inc. negative intrathoracic pressure
• Nasal flaring
• Cyanosis
• Hypothermia
What will the CXR look like for RDS?
• Under-aerated bilaterally
• Clouded
• Opaque
• Reticula granular
• Frosted or ground glass appearance
How will the skin present for a pt with RDS?
• Pallor and/or severe edema
• Flaccid with general hypo-activity
What is used to diagnose RDS?
Shake test
The symptoms of RDS worsens within the first ___ to ___ hours followed by and _____ .
48-72; slow recovery
Stabilization of the disease is often associated with the onset of _____?
Diuresis
The highest incidence of mortality occurs within _____ hours, secondary to complications such as _______?
72; barotraumtic air leaks, intracranial hemorrhage, infections not due to the lung disease
