Figure 6-3 • Breathing System Resistance: 1 = Pressure drop (cm H
= Flowrate (L/min)
Pressure required to open inspiratory or expiratory valves: Dry: 0.49 cm H
Moist: 0.91 cm H

4600 mL including bellows
950 mL canister
Auxiliary Common Gas Outlet: ISO 5356 type
connector on the front of the system (Standard 22
mm OD or 15 mm ID conical friction fit connectors)
These values are for continuous pressure and are
higher than those expected during mechanical
ventilation.
≤ 300 mL/min total at 3 kPa (0.4 psi); ≤75 ml/min
for all connectors and two part tubes and ≤ 225 mL/
min for all other breathing system assemblies
Volume of gas lost due to internal compliance (bag
mode only) 1.82 mL/cm H

Y piece or T piece adds ≤0.15 kPa (.02 psi) expiratory
resistance at 1 L/sec.
To maintain compliance with standards, choose a
patient circuit with low resistance to flow.
