Q

What are Braxton Hicks contractions? When do they occur?

A

irregular, painless, intermittent contractions that facilitate uterine blood flow through the placenta to promote oxygen delivery to the fetus
-can be felt after 4th month of pregnancy

Q

What are some of the cardiovascular adaptations to pregnancy?

A
  • Heart and lungs will be elevated and shift to the left from enlarged uterus
  • Increased blood volume and cardiac output may lead to transient murmurs
  • Pulse increases
  • BP: systolic usually stays the same or slightly decreases, diastolic decreases then gradually increases by term
  • Supine hypotensive syndrome can occur
  • increase in clotting factors (lead to increased risk for clots/DVT/stroke)

Q

How does blood pressure change throughout pregnancy?

A
  • Systolic usually remains the same, may decrease slightly as pregnancy advances
  • Diastolic begins to decrease in the first trimester, continues to drop until 24-32 weeks, then gradually increases and returns to prepregnancy levels by term

Q

What are some of the respiratory adaptations to pregnancy?

A
  • Oxygen requirements increase (leads to increased basal metabolic rate)
  • Estrogen causes increased chest expansion
  • Diaphragm is displaced, thoracic breathing replaces abdominal breathing
  • Upper respiratory tact becomes more vascular (due to estrogen) and creates congestion
  • Lowered threshold for carbon dioxide (become more aware of the need to breathe), slight pH increase
