Doesn't matter.: Elective delivery should be discouraged prior to 39 weeks gestation regardless of lung maturity tests. Babies born electively (with no other medical indication) prior to 39 weeks have higher risks of respiratory distress and nicu admission even when the amnio test demonstrates "lung maturity." if there is a medical reason for delivery, the amnio is unnecessary. ...Read more

Amniocentesis is a procedure used to draw a sample of the amniotic fluid that surrounds and cushions the baby in the womb. This fluid contains cells that have been sloughed off of the developing fetus. Amniocentesis is most often used to detect genetic abnormalities, though the results can also reveal the baby's sex, gauge lung maturity (if done close to term), detect amniotic fluid infections, or ...Read more

What causes babies to ingest milk into their lungs?

Aspiration: The swallowing and breathing tubes use the same mouth and rely on a transitional structure called the epiglottis to close over the breathing tube and allow you to swallow food/fluids. If a baby is breathing in while the fluid is trying to go down, some can sneak passed the epiglottis and be inhaled into the lung. Luckily this rarely happens. ...Read more

Can pulmonary hypertension resolve when my babies chronic lungs grow?

Can pulmonary hypertension resolve when my babies chronic lungs grow?

If chronic lung disease is the result of extreme prematurity (< 28 weeks), the pulmonary hypertension is largely due to an under developed pulmonary vascular bed (smaller arteries and fewer branches). This may not improve, even with good growth and nutrition. While they may improve, it often becomes apparent again after the growth spurt associated with adolescence. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
