Q

Foramen ovale

A

Allows for right to left blood from atria to bypass lungs. Oxygenated blood enters ascending aorta then goes to brain and upper body

Q

Ductus arteriosus

A

Allows lungs to be bypassed and oxygenated blood flows to descending aorta and then to the lower body

Q

What occurs during transitional circulation

A

Pulmonary pressure starts to drop and systemic pressure is more. Blood goes to lungs

Q

Low compliance of newborn lungs increases

A

Work of breathing and created increased effort for ventilation which results in increased respiration rate

16
Q

Patent ductus arteriosus

A

Most common heart defect during neonatal period

17
Q

Tetralogy of fallot

A

Ventricular septal defect, right ventricular outflow obstruction, right ventricular hypertrophy, aortic overide

18
Q

Classical clinical presentation of tetralogy of fallot

A

Cyanosis with crying

19
Q

Atrioventricular defects

A

Large spectrum of defects that affects the atrial, ventricular septum and valves

20
Q

Head down position in neonates and infants is

A

Avoided and often contraindicated

High incidence of GERD

21
Q

Respiratory Distress syndrome

A

Results from lung immaturity and inadequate amount of surfactant results in alveolar collapse

22
Q

RDS is most common

A

Respiratory disorder in preterm infants

23
Q

Maximum Aspiration Syndrome

A

Content of the fetal bowels can be aspirated in first breaths

24
Q

Exercise considerations with cystic fibrosis

A

Bronchial drainage may not be necessary if a regular exercise routine is followed
