What is a common delivery method for oxygen therapy in long-term patients?

Nasal cannula is often the delivery method of choice for long-term oxygen therapy in patients due to several practical advantages it offers. It allows for a low-flow, continuous supply of oxygen that can be comfortably worn for extended periods. Patients can easily eat, drink, and talk while using a nasal cannula, which makes it more convenient and less intrusive compared to other methods. The low-profile design of the nasal cannula also reduces feelings of claustrophobia for some individuals, allowing for better patient compliance with long-term therapy.

In contrast, other oxygen delivery devices mentioned tend to be more suitable for short-term use or specific medical situations. Non-rebreather masks, for example, provide a high concentration of oxygen but are not comfortable for long durations and can impede normal activities. Simple face masks offer a moderate flow of oxygen but still restrict movement and comfort for long-term use. Venturi masks, while excellent for delivering precise oxygen concentrations, are primarily used in acute settings or for patients who require controlled oxygen delivery and are less practical for daily, long-term use.
