Introducing my Friend Nina to Masks - SHORT Version (see profile for extended version) My friend Nina was curious about my collection of medical masks and breathing gear. She was keen to try them and together we filmed this video to capture her initial reactions. In this video she first tries on a mask (a laerdal masks - which I always mispronounce, sorry!), then we pair it with a AMBU bag. First I squeeze the bag for her, then she uses it herself. She takes deep breaths from the AMBU bag, filling her lungs. The whole while we are lightheartedly discussing the look, feel and our impressions.
