What material is a typical reservoir bag made from?

A typical reservoir bag is made from rubber or a similarly elastic material that allows the bag to expand and contract as oxygen is delivered to the patient. Rubber is particularly effective because it provides the necessary flexibility and resilience to hold gas under pressure while also being durable enough to withstand repeated use.

While plastic and silicone can also be used in various veterinary applications, they typically do not provide the same level of stretchability needed for a reservoir bag compared to rubber. Metal is not a practical option for a reservoir bag due to its rigidity and inability to form a flexible seal, which is crucial for the functioning of the anesthesia machine. Therefore, rubber stands out as the most appropriate material for reservoir bags used in veterinary anesthesia.
