The document discusses a study that assessed the effectiveness of an "on the job" training program for noninvasive ventilation (NIV) provided to 66 nurses working in 3 COVID-19 wards. The training program, provided by expert ICU nurses, consisted of 3 hour sessions covering management of helmet-CPAP and NIV with masks. Nurses completed an 11-item self-assessment survey before and after the program to evaluate their skill levels. The results showed significant improvements in self-reported skills for managing helmet-CPAP and mask NIV after completing the training program. The study concludes that "on the job" training by expert ICU nurses can effectively implement new NIV skills for non-ICU nurses during times of high
