Spirometry: don't blow it!

Area of Science:

• Pulmonary Medicine
• Diagnostic Testing

Background:

• Spirometry is a widely used pulmonary function test.
• Ensuring spirometry accuracy involves overcoming variability in performance and interpretation.

Purpose of the Study:

• To outline the critical steps for performing and interpreting spirometry.
• To highlight factors influencing spirometry validity and clinical utility.

Main Methods:

• Review of spirometry performance techniques.
• Analysis of criteria for test validity.
• Examination of interpretation methodologies.

Main Results:

• Spirometry maneuver technique is straightforward but prone to variability.
• Specific criteria are necessary for test validity.
• Accurate interpretation depends on technical soundness, reference population comparison, and clinical context.

Conclusions:

• Proper spirometry performance, patient coaching, and maximal effort are crucial.
• Accurate interpretation requires adherence to established schemes and clinical correlation.
• Errors in spirometry can lead to misdiagnosis and negatively affect patient care.
• Understanding coding and billing is vital for provider reimbursement.
