Due to dilation in heart-or can also have inc. rBbb
What happens to Protein C and S during pregnancy?
Protein S decreases, and there develops a resistance to protein C (both are anticoagulants).
What happens to plasma volume during preggo? Erythrocytes mass? FRC? SVR? Hct?
It increases by 40%, but erythrocytes mass only increases by 20%, leading to a decreased HCT-physiologic anemia of pregnancy. SVR decreases to normalize afterload I’m setting of increased cardiac output
ACLS stuff is different for pregnant women-Hiw Sway? What’s the same?

EKG changes seen in people with too much magnesium? When are DTRs lost? What does it do to BP?
Widening if WRS and prolongation of PR interval. At 10 mg/mL. Mg causes hypotension and decreased SVR, and it potentials NM block
