Name of the Procedure:

Common Name: Peak Expiratory Flow Rate Measurement
Technical Term: Peak Expiratory Flow Rate (Physician Services)
HCPCS Code: S8110

Summary

The Peak Expiratory Flow Rate (PEFR) measurement assesses how well your lungs expel air. This non-invasive test helps monitor breathing and determines how well your asthma or other lung conditions are managed.

Purpose

Medical Conditions Addressed:

• Asthma
• Chronic obstructive pulmonary disease (COPD)
• Other respiratory conditions

Goals:

• To measure airflow obstruction.
• To monitor lung function over time.
• To adjust treatment plans based on lung performance.

Indications

Symptoms or Conditions:

• Persistent cough
• Shortness of breath
• Wheezing
• Recurrent respiratory infections

Patient Criteria:

• Diagnosed with or suspected of having asthma or COPD
• Experiencing symptoms of respiratory distress
• Undergoing treatment for lung conditions

Preparation

Pre-Procedure Instructions:

• No specific fasting or preparation required.
• Avoid using your quick-relief inhaler for 4-6 hours before the test, if advised by your doctor.

Diagnostic Tests:

• A prior spirometry test may be recommended to provide baseline lung function data.

Procedure Description

1. Preparation:

   • The patient will stand or sit upright.
   • The patient will take a deep breath in, filling their lungs completely.

2. Execution:

   • The patient will place their lips tightly around a Peak Flow Meter.
   • They will exhale as forcefully and quickly as possible into the device.

3. Tools Used:

   • Peak Flow Meter (a handheld device).

4. Anesthesia/Sedation:

   • Not applicable.

Duration

• The procedure typically takes about a few minutes but can be repeated multiple times to ensure accuracy.

Setting

• Usually performed in a doctor's office, outpatient clinic, or at home.

Personnel

• Performed by a physician, nurse, or respiratory therapist.
• Can also be done by the patient at home with proper instruction.

Risks and Complications

Common Risks:

• Rare and minimal, primarily hyperventilation or dizziness.

Rare Risks:

• In rare cases, forceful exhalation might induce a coughing fit or breathlessness.

Management:

• Usually self-resolving; patient advised to rest and breathe normally if they experience light-headedness.

Benefits

• Provides immediate insight into lung function.
• Helps in making real-time decisions about asthma or COPD management.
• Empowers patients with daily monitoring of their respiratory health.

Recovery

Post-Procedure Care:

• No specific care needed.
• Resume normal activities immediately.

Expected Recovery Time:

• Instantaneous.

Follow-Up:

• Regular tracking of PEFR at the same time each day, as advised by a doctor.
• Follow-up appointments to review PEFR readings and adjust treatment plans.

Alternatives

• Spirometry: More comprehensive but time-intensive test.

  • Pros: Provides a detailed analysis of lung function.
  • Cons: Requires more specialized equipment and trained personnel.

• Pulse Oximetry: Measures oxygen saturation rather than airflow.

  • Pros: Non-invasive and quick.
  • Cons: Does not provide direct insights into airflow obstruction.

Patient Experience

During the Procedure:

• The patient may experience temporary dizziness or light-headedness from forceful exhalation.
• The procedure is generally painless.

After the Procedure:

• No significant discomfort or pain expected.
• Patients can resume their daily activities immediately.

Pain Management:

• Not applicable, as the procedure is non-invasive and not typically painful.
