volume of breath? 6 litres

our units are approximately 1/5 a litre

|
o2 below 19.5% is considered dangerous
|
|
0.47 pressure at 21% is lowest pressure
|
|
- 5 to 8 psi for 100% is tolerable (1 psi = 0.068046 atm)
|
|
(should be roughly 0.12 atm (minimum at 100%))
|
|
2.5 atm at 21% should be a safe maximum, short periods in excess of 70 atm are tolerable
|
|
|
|
Min Pressure: 0.12 atm with pure oxygen
|
|
Max Pressure with pure oxygen: 0.5 atm

Min Pressure w 19.5-21%: 0.47 atm

Max Pressure with 19.5-21%: 2.5 atm
