PULMONARY FUNCTION TEST ARTERIAL BLOOD GAS

Pulmonary Function Test (PFT) with Arterial Blood Gas (ABG) analysis is a comprehensive respiratory assessment used to evaluate lung performance, breathing capacity, oxygen exchange, and blood gas levels. This combined examination provides detailed information about how effectively the lungs deliver oxygen to the bloodstream and remove carbon dioxide from the body.

The Pulmonary Function Test measures lung volumes, airflow, and breathing efficiency, while the Arterial Blood Gas test analyzes oxygen, carbon dioxide, blood pH, and acid-base balance from an arterial blood sample. Together, these tests help diagnose and monitor a wide range of respiratory and pulmonary disorders.

This evaluation is commonly recommended for patients with breathing difficulties, chronic lung disease, asthma, COPD, pulmonary fibrosis, respiratory failure, and other conditions affecting lung function and oxygenation.

Benefits of the Test

• Provides comprehensive assessment of lung function.
• Measures oxygen and carbon dioxide levels in blood.
• Helps diagnose asthma and COPD.
• Evaluates respiratory efficiency and gas exchange.
• Assesses severity of lung diseases.
• Monitors treatment response and disease progression.
• Supports pre-operative respiratory evaluation.
• Assists in managing chronic respiratory conditions.

Why Doctors Recommend This Test

Doctors may recommend PFT with ABG for patients experiencing chronic cough, shortness of breath, wheezing, low oxygen levels, respiratory failure, suspected lung disease, pulmonary fibrosis, COPD, asthma, or unexplained breathing difficulties.

The test helps determine the severity of respiratory conditions and guides appropriate treatment planning.

Preparation Before Test

• Avoid smoking before the test.
• Avoid heavy meals immediately before the examination.
• Wear comfortable clothing.
• Inform your doctor about respiratory medications.
• Follow instructions regarding inhaler use.
• Avoid strenuous physical activity before testing.

Normal Reporting Time

Most Pulmonary Function Test with Arterial Blood Gas reports at Focus Diagnostics are available within 2–3 hours after completion of the examination.

Who Should Take This Test?

This test may be recommended for:

• Individuals with breathing difficulties.
• Patients with asthma or COPD.
• People with chronic lung disease.
• Individuals with low blood oxygen levels.
• Patients with pulmonary fibrosis.
• People requiring respiratory assessment before surgery.
• Individuals with unexplained respiratory symptoms.
• Patients requiring detailed pulmonary evaluation.

Detailed Information

The Pulmonary Function Test evaluates how effectively the lungs move air in and out, while the Arterial Blood Gas analysis measures oxygenation, ventilation, and acid-base status directly from arterial blood. Together, these tests provide a comprehensive picture of respiratory health.

The combined examination is particularly useful in assessing chronic respiratory diseases, monitoring treatment effectiveness, determining oxygen therapy requirements, and evaluating patients with severe pulmonary conditions.

ABG analysis helps identify respiratory failure, oxygen deficiency, carbon dioxide retention, and metabolic imbalances that may affect breathing and overall health. The results are valuable for pulmonologists in diagnosing and managing complex respiratory disorders.

At Focus Diagnostics, Pulmonary Function Testing and Arterial Blood Gas analysis are performed using advanced diagnostic equipment to ensure accurate results and timely reporting.
