Disposable sterile infusion sets are categorized by function into standard, precision filtration, fine-tuning, burette, drip, and light-protected types. Precision filtration infusion sets utilize nuclear pore membranes to filter 5μm particles and are suitable for children and critically ill patients.
When administering intravenous fluids with a syringe, healthcare professionals typically remove all air. If small air bubbles are present, they will rise as the fluid is injected, generally preventing them from being pushed into the body.
Very small amounts of air entering the body generally pose no danger.
However, if a large amount of air enters the body, it can cause pulmonary artery blockage, preventing blood from reaching the lungs for gas exchange and endangering life.
Generally, air entering the body will trigger an immediate reaction, such as chest tightness and shortness of breath, indicating severe hypoxia.
