Fetal Biophysical Profile (BPP) Score

Description

Calculates the Fetal Biophysical Profile score to assess fetal well-being and identify risk of fetal hypoxia or acidosis. The profile evaluates five parameters: Non-Stress Test (NST), Amniotic Fluid Volume, Fetal Breathing Movements, Fetal Tone, and Fetal Body Movements. Each parameter is scored as 2 (Normal) or 0 (Abnormal).

Usage

fetal_biophysical_profile(nst_reactive, amniotic_fluid_volume,
                          fetal_breathing_movements, fetal_tone,
                          fetal_body_movements)

Arguments

nst_reactive	Numeric (0 or 2). Non-Stress Test result. 2: Reactive (>=2 accelerations of >=15 bpm for >=15 sec in 20 mins). 0: Non-reactive (<2 accelerations in 40 mins).
amniotic_fluid_volume	Numeric (0 or 2). Amniotic Fluid Volume. 2: Single deepest vertical pocket > 2 cm. 0: Largest pocket <= 2 cm (Oligohydramnios).
fetal_breathing_movements	Numeric (0 or 2). Fetal Breathing. 2: >= 1 episode of rhythmic breathing lasting >= 30 sec within 30 mins. 0: < 30 sec of breathing in 30 mins.
fetal_tone	Numeric (0 or 2). Fetal Tone. 2: >= 1 episode of extension of a fetal extremity with return to flexion (or opening/closing of hand). 0: Slow extension with partial return or no movement.
fetal_body_movements	Numeric (0 or 2). Fetal Movements. 2: >= 3 discrete body/limb movements within 30 mins. 0: < 3 movements.

Value

A list containing:

BPP_Total_Score	The sum of the 5 component scores (Range 0-10).
Risk_Assessment	Interpretation of fetal well-being (Normal, Equivocal, or Asphyxia).
Management_Guidance	Clinical recommendations based on the score and amniotic fluid status.

Examples

# Example 1: Normal
# All parameters normal
fetal_biophysical_profile(2, 2, 2, 2, 2)

# Example 2: Equivocal (Score 6)
# Non-reactive NST, No breathing, others normal
fetal_biophysical_profile(0, 2, 0, 2, 2)

# Example 3: Oligohydramnios (Score 8 but AFV=0)
# All normal except fluid
