Definition
High flow: exceeds pt insp flow, delivers 1.00 FIO2 - nonrebreathing mask, high flow cannula.
Low flow: <10 l/m; pt inspiratory flow exceeds delivery. standard nasal cannula, simple O2 mask |

Definition
count big boxes in R-R interval
1 big box between = 60/0.2 = 300 bpm
2 big boxes = 150
3 = 100
4 = 75
5 = 60
>5 boxes in between = bradycardia
<3 boxes in between = tachycardia |
