Which adjustment would help a patient experiencing claustrophobia while using a Venti mask?

A nasal cannula at 6 L/min is an effective adjustment for a patient experiencing claustrophobia while using a Venturi mask because it provides a less restrictive and more comfortable delivery system. Patients with claustrophobia often feel anxious or panicked in situations where they feel confined or have a mask covering their face. The nasal cannula, which sits comfortably in the nostrils, allows for greater freedom and ease of movement and does not obscure the patient's face, thereby reducing feelings of anxiety.

Additionally, delivering oxygen through the nasal cannula at 6 L/min can still ensure sufficient oxygenation for patients requiring supplemental oxygen, particularly if they are stable and do not necessitate the precise oxygen concentration provided by a Venturi mask. This flow rate allows for a mild degree of oxygen enrichment while still maintaining patient comfort, making the nasal cannula a good choice in cases where anxiety affects compliance with other oxygen delivery methods.

In contrast, using a simple mask or a partial rebreather mask would still involve some level of facial coverage that could exacerbate feelings of claustrophobia. Therefore, by opting for the nasal cannula, the patient can be more relaxed and may be more likely to adhere to their oxygen therapy.
