Pattern Recognition & Intervention

Key components to assess during fetal monitoring include:
- Fetal heart rate (FHR) baseline
- FHR variability
- FHR accelerations
- FHR decelerations
- Normal and abnormal uterine activity
- Fetal dysrhythmias
- Maternal complications
- Uteroplacental complications
- Fetal complications

Fetal Heart Rate (FHR) Descriptors

Primary descriptors used in assessing FHR:
- Baseline
- Variability
- Presence of accelerations
- Presence of decelerations
- Changes in trends over time

FHR Baseline

Defined as the average FHR rounded to the nearest 5 bpm over a 10-minute window.
Normal range is 110 to 160 bpm and must exclude accelerations, decelerations, and marked variability.
A minimum of 2 minutes is needed to establish a baseline, which can be non-continuous.

Fetal Bradycardia

Defined as a significant drop in FHR below normal ranges with a minimum threshold of 25 bpm.
Clinical significance remains unclear with such an indeterminate baseline.

Variability in FHR

Minimal variability: ≤5 bpm, detectable; may indicate sleep, sedation, or illness.
- Sleep cycles last 20-60 minutes.
- Sedated states (due to CNS depressants like magnesium) last 1-2 hours.
- Illness (acidemia) remains unresolved and requires prioritizing oxygenation.
Moderate variability: 6 to 25 bpm; signifies absence of metabolic acidosis, even in presence of decelerations.

FHR Accelerations

Predicts absence of metabolic acidemia, whether spontaneous or stimulated.
Defined by onset to peak occurring within 200 Montevideo Units (MVUs) and associated with 6 hours of inadequate contractions.

Fetal Dysrhythmias

SVT (Supraventricular Tachycardia): Heart rates range from 210 to 300 bpm; treatment includes digoxin.
- Associated risks: hydrops, congestive heart failure, increased oxygen demand.
Congenital heart block: Ranges from 140 to 90 bpm; treatments involve calcium channel blockers, thiazides, and beta-blockers.

Cord Blood & Acid Base Balance

Measures oxygenation at delivery.
Base deficit or excess of +/-12 indicates immediate clinical implications, while normal bicarbonate levels suggest overall stability.
Metabolic acidosis characterized by normal CO2 and decreased bicarbonate.

Intrauterine Pressure Catheter (IUPC)

Measures uterine pressure during labor, assessing contraction intensity and resting tone.
Requires rupture of membranes (ROM) and cervical dilation for insertion to the 35-45 cm mark.
Risks include possible placental or uterine perforation and infection.

Artifacts in Monitoring

Artifacts manifest as vertical lines in tracing, caused by interference during recording.
Causes include vaginal exams, fetal movement, or connection issues; necessary to rule out arrhythmia.

Signal Ambiguity

Occurs when EFM inadvertently picks up maternal heart rate or signals from another fetus.
Verifying with pulse oximeter, internal scalp electrode (ISE), or fetoscope is essential.

Professional Issues in EFM

Key components include:
- Legal considerations
- Ethical standards
- Patient safety
- Quality improvement practices

Legal Considerations

Informed consent must include procedure risks, benefits, and alternatives.
Consent is implied in emergencies and can be revoked at any time.
Negligence defined as breach of duty leading to damages; malpractice denotes professional negligence causing harm.

Ethical Principles

Core principles include:
- Autonomy: honoring patient decision-making
- Veracity: commitment to truthfulness
- Fidelity: obligation to uphold commitments
- Justice: ensuring equal treatment
- Beneficence & nonmaleficence: promoting good while preventing harm.
- Confidentiality and privacy protections.

Patient Safety Measures

Sentinel events are critical safety events resulting in patient harm or death.
Frequent communication breakdowns are major contributing factors; SBAR (Situation, Background, Assessment, Recommendation) can enhance communication.

Quality Improvement Initiatives

Focus on measurable improvement in patient care outcomes.
Standard of care represents expected provider actions to avoid harm.
Evidence-based practice (EBP) refers to applying best practices supported by research and guidelines.
Validity pertains to the accuracy of measures, whereas reliability concerns the consistency of results.
