What is the main purpose of a drip chamber in IV therapy?

The main purpose of a drip chamber in IV therapy is to allow for visualization of the flow rate and to trap air bubbles. The drip chamber is a transparent container that holds a small amount of intravenous fluid and is designed to enable healthcare providers to monitor the rate at which the fluid is infusing. This visualization is crucial for ensuring that the patient receives the correct amount of fluid over the appropriate timeframe.

Additionally, the drip chamber plays an essential role in capturing any air bubbles that might enter the IV line. If air bubbles were to reach the bloodstream in significant quantities, they could lead to complications such as air embolism. Therefore, the design of the drip chamber helps to maintain the integrity of the IV fluid delivery system and contributes to patient safety by preventing such occurrences.

The other options do not capture the primary function of the drip chamber. While increasing fluid pressure, providing medication administration, or decreasing fluid volume may be associated with different aspects of IV therapy, they do not relate to the specific role of the drip chamber in flow monitoring and air bubble prevention.
