Prior to connecting to the patient airway, verify that there are no leaks in the

sample line, water trap, and gas analyzer filter by sealing the end of the sample

line with your thumb. After approximately 15-seconds, the Occlusion LED lights

and an occlusion message appears on the monitor. If this does not occur within

30-seconds, check for an air leak by removing and carefully reinstalling the water

trap, the gas analyzer filter, and/or the sample line. Repeat the test.

Closed Circuit Tracheal Suction Systems

Closed circuit tracheal suction systems (such as those provided by Ballard)

extend the life of the endotracheal tube and associated tubing by allowing the

endotracheal tube to be periodically suctioned without detaching it from the

ventilator circuit. Spacelabs Medical recommends use of Ballard Model #221

elbow closed tracheal suction systems, or similar systems, with Spacelabs

Medical capnography units. Such a system allows the Spacelabs Medical airway

adapter to be placed outside the tube through which fluids are being suctioned,

reducing the chance of occluding the airway.

Spacelabs Medical does not recommend use of traditional setups that require the

airway adapter to be in line with the endotracheal tube. However, if you prefer a

traditional setup such as the Ballard Model 2205 style, using the Ballard Model

112 adapter moves the airway adapter away from the suction catheter.

Figure 22-5 shows examples of setups using the Ballard Model #221 and Model

2205 style (with Model 112 adapter). Similar closed systems, such as the Concord

Portex (not shown), must be placed in the ventilator circuit in the same positions

as shown in Figure 22-5.

WARNING:

• Always test the sampling line adapter for a tight

connection and proper operation before attaching to a

patient.
