Why are pipeline inlet connections designed to be perpendicular to the floor?

Pipeline inlet connections are designed to be perpendicular to the floor primarily to prevent kinking and wear from gravity. When connections are positioned perpendicular, it allows the gas supply lines to hang freely without unnecessary bends or loops that could create stress points. This orientation ensures that there is a smooth and unobstructed path for gases to flow, minimizing the risk of wear on the tubing, which might lead to leaks or failures over time. Gravity can pull down on hoses that are not positioned correctly, leading to potential kinks that obstruct flow or compromise the integrity of the connection. Therefore, this design choice enhances the safety and longevity of the anesthesia delivery system by maintaining optimal gas delivery conditions.
