Answer #1

Patent ductus arteriosus

It is a heart defect that causes opening between two blood vessels leading from heart.

The abnormal opening causes too much blood to circulate to the neonates heart and lungs .it may leads to increase in the blood pressure in the lungs that is pulmonary hypertension and the neonates heart enlarges and it becomes weak and may lead to fatal condition.

2.

During the first breath there is increased oxygen in the lungs causes decreases in blood flow resistance to lungs.

Blood flow resistance of baby's blood vessels also increases.

Cardiovascular and respiratory functions are highly integrated. We have already spent some time discussing how cardiac pathologies can lead to pulmonary oedema. Now let’s take that to the next step in considering the following questions. Consider what effects pulmonary oedema will have on circulating blood gasses. How will this affect systemic arterioles, how will that impact TPR, and how the body will compensate for this change. (Select three answers). Group of answer choices Systemic arterioles will dilate Systemic arterioles will...
