Respiratory Distress Syndrome Flashcards
Respiratory Distress Syndrome is formerly termed as
Hyaline Membrane Disease
Respiratory Distress Syndrome is most often seen in
Newborns born prematurely
What is the pathologic feature of Respiratory Distress Syndrome is
A hyaline-like (fibrous) membrane
The needed pressure to inspire first breath
Between 40 and 70 cm H2O
CPAP
Continuous positive airway pressure
Peep
Positive end-expiratory pressure
A potent vascular dilator
Nitric Oxide
Causes pulmonary vasodilation without decreasing systemic vascular tone
Nitric Oxide
Means of oxygenating blood during cardiac suegery
Extracorporeal Membrane Oxygenation
Synthetic surfactant is administered into an endotracheal tube by a syringe or catheter
Lung lavage
What tocolytic agent can help prevent preterm birth
Magnesium Sulfate
Quickens the formation of lecithin
Steroids/glucocorticosteroids
What injections may prevent RDS
Two injections of a glucocorticosteroid such as betamethasone
What is the advantage of CPAP or PEEP
The pressure exerted on the aleveoli at the end of expiration and helps keep alveoli from collapsing
When does surfactant forms
Starting 34th week of gestation
the needed pressure to maintain quiet and continued breathing
15 to 20 cm H2O
the phospholipid that normally lines the alveoli and reduces surface tension to keep the alveoli from collapsing on expiration.
Lung Surfactant
Surfactant does not form until what week
34th week of gestation
________ occurs caused by closure of the glottis as it tries to increase the pressure in the alveoli on expiration
Expiratory Grunting
Tissue Hypoxia causes the release of
lactic acid
On inspiration, the anterior chest wall retracts and the abdomen protrudes; on expiration, the sternum rises
Seesaw respirations
This infection in newborns is so severe that it may stop surfactant production
B-hemolytic, GBS infection
Following surfactant administration, the newborn should be placed in what position.
Elevated position of the head.
the advantage of CPAP and PEEP in addition to supplying oxygen
Pressure is exerted on the alveoli at the end of expiration
It causes pulmonary vasodilation without decreasing systemic vascular tone.
Nitric Oxide
A neonate with RDS must be kept warm because cooling increases ______ in newborns.
acidosis
quickens the formation of Lecithin
Betamethasone
Steroid betamethasone does not take effect before what time
24 hours to 48 hours
