Measure air pressure on the bag, air flow inside tracheal tube

Blood pressure cuff around the bag

partially inflated this provides pressure on bag,squeeze the blood pressure cuff rather than the bag directly.

Attach a manometer to facemask to get confirmatory mouth air pressure

from https://old.reddit.com/r/pics/comments/foo7qm/italian_guy_designed_a_3d_printable_valve_to_turn/ [–] Vandimal88 184 points 14 hours ago   It looks like it would essentially work as non-invasive positive airway pressure similar to CPAP or BIPAP. That still uses positive pressure to force air into the lungs but without a tube that goes down the trachea past the vocal cords. There are many limitations on this kind of ventilation compared to intubation. With intubated patients you can control parameters such as positive end expiratory pressure (PEEP) which helps stent open the alveoli when they fill with fluid (acute respiratory distress syndrome) which is a common complication from COVID-19. You can’t reliably control all of these parameters with non-invasive positive airway pressure because it relies on the patient to be able to take their own breaths. They can tire out or if their mental status deteriorates and they are not able to maintain their airway ...
