Conclusion: This study demonstrates that MANIV successfully enabled consistent 30sec MANIV-BH after just a single coaching session thanks to optimised ventilation settings defined by an experienced physiotherapist. A significant reduction in treatment session times was observed, indicating improved efficiency across the sessions. By observing the median parameters, we can adapt patient-accepted parameters, thereby enhancing the process. Further studies should include a larger patient cohort to refine these parameters based on specific patient profiles. This would allow precise control of ventilation parameters for the successful implementation of MANIV, while ensuring patient comfort and treatment efficiency. Better defining MANIV parameters remains crucial to enhance its broader and easier application in radiotherapy. References: 1.

Approximately one-third of patients with cancer who receive radiotherapy experience clinically significant psychosocial distress (2). Radiation therapists (RTTs)/therapeutic radiographers (TRs) are typically the only healthcare professionals in direct contact with patients each day during their treatment. RTTs/TRs can help reduce patient anxiety and distress and their impact on supporting patients should not be underestimated. This study aimed to target clinically practicing RTTs in Ireland and TRs in the United Kingdom (UK) to investigate their perceptions of providing support to psychosocially distressed cancer patients undergoing radiotherapy. Material/Methods: Ethical approval was granted. An online anonymous cross-sectional survey was posted on social media platforms and sent via professional networks. The target demographic was clinically practicing RTTs/TRs. RTTs/TRs were asked about their comfort levels regarding anxiety and depression symptom management, how often they provide specific education/management options for symptoms, and if they felt they would benefit from further education in this area. A two sample t-test examined differences in RTT/TR comfort levels in providing treatment and support to patients suffering from anxiety and depression. Results: One hundred and twenty-six responses were received; 114 (90.5%) completed all questions. RTTs/TRs felt more comfortable recognising, asking about, and making recommendations for anxiety than depression (p<0.001). RTTs/TRs with >10 years’ experience felt more comfortable managing depression than those with ≤ 10 years’ 2771
