Physiologic Changes in Pregnancy[2]
- Heart rate (HR) increases 15-20 bpm (75-95 bpm)
- Mean arterial pressure (MAP) increases 10 mmHg (80 mmHg)
- Tidal volume (TV) increases 40% (700 cc)
- Minute volume (MV) increases 40% (10.5 L/min)
- Functional residual capacity (FRC) decreases 25% (1300ml)
Maternal Laboratory Changes in Pregnancy[3]
- Increased ESR ~78
- Decreased PaCO2 ~30
- ECG with Qs in III & aVF, left axis
- Beta-HCG Levels
- Decreased hematocrit (32-34%) due to increased plasma volume
- Decreased BUN and creatinine (<0.8mg/dL)
- GFR increases up to 60% (140ml/min)
