Physiologic Adaptations During Labor and Birth
Pathophysiology
Labor causes dynamic cardiovascular, respiratory, musculoskeletal, endocrine, and uterine changes that support fetal descent and birth while preparing rapid postpartum hemostatic transition.
Nursing Assessment
- Trend vitals, oxygenation, and temperature for expected versus pathologic change.
- Monitor uterine activity, descent progress, and postpartum involution.
- Assess for hemorrhage cues, bladder distention, and medication-related adverse effects.
Nursing Interventions
- Support physiologic labor with movement, hydration, and stage-appropriate monitoring.
- Anticipate and intervene for hemorrhage risk in third/fourth stage.
- Coordinate rapid escalation for instability or concealed bleeding concern.
