Standards of a BVM

Question 1

list the 12 standards of design for a BVM

Answer 1

1. deliver at least 85% o2 with flow of 15LPM
2. operate at extreme temps (-180 to 600dgC and RH of 40-96%)
3. adult: must at least deliver Vt 600ml; Cs of 0.02 L/cmh2o and R of 20 cmh2o/L/sec
4. neonates: must at least deliver Vt 200-300mls

pediatric: must at least deliver Vt 400-500mls

5. flows 0-30LPM without jamming non-rebreathing valve
6. malfunctioning valve d/t foreign obstruction must be restored w/in 20sec
7. 15:22mm connector
8. no pressure limiting system on adult BVM
9. pressure release valve at 40 cmh2o (+/- 10) for paediatric BVM
10. pressure release valve at 40 cmh2o (+/- 5) for neonatal BVM
11. override capability & audible signal if pressure limiting/venting system in place
12. operate properly after being dropped from height of 1m onto concrete
