PFT Score Calculation:
From: | To: |
The PFT (Pulmonary Function Test) Score is calculated by summing various test results to assess overall pulmonary function. It provides a comprehensive evaluation of lung capacity and respiratory health.
The calculator uses the PFT equation:
Where:
Explanation: The equation sums individual test results to provide a comprehensive pulmonary function score.
Details: The PFT Score is crucial for diagnosing respiratory conditions, monitoring disease progression, and evaluating treatment effectiveness in pulmonary patients.
Tips: Enter all test results in their respective units. Ensure values are valid (≥0) for accurate calculation.
Q1: What tests are typically included in PFT?
A: Common tests include spirometry, lung volumes, diffusion capacity, and airway resistance measurements.
Q2: What is a normal PFT Score range?
A: Normal ranges vary based on age, gender, height, and ethnicity. Scores are typically compared to predicted normal values.
Q3: When should PFT be performed?
A: PFT is recommended for patients with respiratory symptoms, smokers, pre-operative assessment, and monitoring known lung diseases.
Q4: Are there limitations to PFT scoring?
A: Results can be affected by patient effort, technical factors, and individual variability. Clinical correlation is always necessary.
Q5: How often should PFT be repeated?
A: Frequency depends on the clinical condition, typically ranging from every 3-12 months for chronic disease monitoring.
