Cânula Nasal

Nasal Cannula or Glasses-Type Catheter 1L of oxygen in the nasal cannula corresponds to 4%. Ambient air corresponds to 21%, so the first liter of oxygen in the catheter will correspond to 24%. 1L = 24% 2L = 28% 3L = 32% 4L = 36% 5L = 40% 6L = 44% It is interesting to think about another device, if this one keeps the O2 Sat below 90%.
