Flashcards in PE in Pregnancy Deck (9)
Initial diagnostic test for suspected PE in pregnancy?
Spiral CT or MRA
Pulse oximetry reading less than 90% corresponds to an oxygen tension of?
When to consider giving oxygen?
Less than 60 mm Hg
PO2 < 95
Nonpregnant versus pregnant values:
1. 7.4 versus 7.45 (respiratory alkalosis with partial metabolic compensation)
2. 90-hundred versus 95-105 (increased tidal volume increases minute ventilation)
3. 40 versus 28 (increased title volume increases minute ventilation)
4. 24 versus 19 (renal excretion of bicarb to compensate for respiratory alkalosis)
Large cardiac silhouette during pregnancy may indicate? Treatment?
Diuretic and ionotropic therapy
Patient with dyspnea – think PE if?
Clear CXR in the face of hypoxemia
Patient with confirmed PE – regimen?
1. 5-7 days for IV therapy
2. Then Subcutaneous heparin to maintain PTT between 1.5-2.5 for three months
3. Then Prophylactic heparinization for remainder of pregnancy and six weeks postpartum
