Background: Body plethysmography is a non-invasive method used to determine static lung volumes and measure air-way resistance in the lungs. It provides valuable information about respiratory function that cannot be determined by spirometry alone. In Nigeria, where respiratory conditions are a significant health concern, the use of body plethysmography can play a crucial role in improving the quality of care for patients with respiratory issues. However, despite its importance, there is a lack of readily available body plethysmography in Nigeria. This research also describes the current equipment available, the principle, patient preparation, the procedure, the interpretation of results and helps to identify barriers and challenges in implementing body plethysmography in the country. Main text: Body plethysmography determines the total volume of gas in the lungs at the end of tidal expiration known as the Functional Residual Capacity (FRCpleth). Total Lung Capacity (TLC) and Residual Volume (RV) are then determined by a linked or unlinked Slow Vital Capacity (SVC) manoeuvre. Plethysmographic measurements are based on Boyle's law. The test usually takes about 15 - 20 minutes to complete. Current guidelines recommend that three or more technically acceptable FRC measurements be made. They must have a repeatability within 5% of each other. Their associated spirometry manoeuvres (SVC) should also meet the acceptability and repeatability criteria. Conclusion: Body plethysmography is a highly informative, non-invasive method for obtaining information about lung volumes not determinable by spirometry as well as airway resistance. This test is often used to diagnose conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. The lack of lung body plethysmography in Nigeria has serious consequences for the health and well-being of the population. To address this issue, increased funding for healthcare infrastructure and equipment, training programs for respiratory technicians, and collaboration with international organizations are crucial steps that must be taken.
