What is the typical flowrate for the Oxygen pressure reducer in the BG4 system?

The typical flowrate for the Oxygen pressure reducer in the BG4 system is 1.5 - 1.9 liters per minute. This range is designed to ensure that the user receives a consistent and adequate supply of oxygen while ensuring safety and efficiency during rescue situations. The flowrate is crucial for maintaining proper oxygen levels in the breathing apparatus, helping to prevent hypoxia and ensuring that the rescue personnel can function effectively in environments where breathable air may be compromised.

Options outside this range either provide significantly less oxygen, which could be inadequate in emergencies, or more oxygen than necessary, which might lead to safety risks associated with oxygen toxicity or wastage. Thus, the selected range ensures a balance between sufficient oxygen delivery and maintaining system integrity during use.
