Final answer:
Sterile coolants or irrigants are typically delivered using a pressurized system, which helps maintain the sterility of the substance and provides an even and effective application.
Step-by-step explanation:
Sterile coolants or irrigants must be delivered using a pressurized delivery system to ensure that they are applied evenly and effectively while maintaining their sterility.
This is vital in medical procedures to prevent infections and ensure the safety and health of the patient. The delivery system uses high pressure to dispense the sterile fluid to the desired area without the risk of contamination that may occur with systems that are less controlled.
