Which oxygen delivery system is best suited for patients needing mobility?

The reservoir cannula is particularly well-suited for patients needing mobility because it allows for the delivery of supplemental oxygen while enabling patients to engage in activities without being tethered to bulky equipment. This system features a reservoir that holds a small amount of oxygen for use during inhalation, which alleviates the need for continuous oxygen flow. As a result, patients can enjoy greater freedom of movement compared to other oxygen delivery systems that might be less portable or more cumbersome.

In contrast, a simple mask can be restrictive and tends to limit mobility, as it needs to remain in place and may require a different setup. The transtracheal catheter, while allowing for more discreet oxygen delivery, may not always be comfortable or practical for all patients, especially for those who are very active. The nasal catheter can also provide mobility, but it typically doesn’t offer the same level of efficient oxygen conservation as the reservoir cannula, which can better meet patients' needs while they are moving about. Therefore, the reservoir cannula stands out for those requiring both effective oxygen delivery and mobility.
