A
30 L bag or 20 L ventilator capacity!
4
Q

maintenance (rebreathing systems)
A
50-100 mL/kg/min
20-50 mL/kg/min
6
Q
LA (>50kg) O2 flow rate for induction/recovery
maintenance
A
20-50 mL/kg/min
10-20 mL/kg/min
7
Q

8
Q
How to calc remaining O2 in tank
A
(660 L/2200 psi) = (x L/psi left on E tank)
* if H tank then 6600 L/2200 psi
