Common Childhood Illnesses: CHD

Question 1

what does acyanotic CHD mean

Answer 1

• increased pulmonary bld flow

Question 2

what does cyanotic CHD mean

Answer 2

• decreased pulmonary blood flow

Question 3

what specific heart defects commonly cause increased pulmonary blood flow

Answer 3

• atrial septal defect
• ventricular septal defect
• patent ductus arteriosus

Question 4

what pulmonary issues come with increased pulmonary blood flow

Answer 4

▷ Abnormal connection between two sides of heart
▷ Increased blood volume on right side of heart
▷ Increased pulmonary blood flow
▷ Decreased systemic blood flow

Question 5

explain what happens when there is a hole between the two sides of the heart.

Answer 5

-the non-oxygenated blood mixes with oxygenated blood
- heart gets too much oxygenated blood -> heart and lungs work harder

Question 6

what specific heart defects commonly cause decreased pulmonary blood flow

Answer 6

• tetralogy of fallot
• tricuspid atresa

Question 7

what four heart anomalies does tetralogy of fallot involve

Answer 7

• pulmonary valve stenosis
• ventricular septal defect
• shifting of the aorta
• right ventricular hypertrophy

Question 8

how is pulmonary blood flow decreased with CHDs

Answer 8

In certain congenital heart defects, an increase in pressure on the right side of the heart relative to the left side leads to the mixing of desaturated (deoxygenated) blood with oxygenated blood in the left side of the heart, resulting in reduced oxygen content in the systemic circulation.
