Hang time for tube feeding in open versus closed systems is limited to how long?

Explanation:
Hang time depends on how protected the formula is from contamination. Open systems expose the formula to air and handling, so the safest practice is to discard after 8 hours to minimize infection risk in older adults. Closed systems are prefilled and sterile, which dramatically lowers contamination risk and allows a longer window—up to 48 hours when stored and handled properly. The other time frames would either increase contamination risk for open systems or exceed typical safe use for closed systems.
