Measure CO2
Before you begin, read the Microstream CO2 sampling line's directions for use.
WARNING Loose or damaged connections can compromise ventilation or
cause an inaccurate measurement of respiratory gases. Securely connect
all components and check connections for leaks according to standard
clinical procedures.
WARNING When using a sampling line for intubated patients with a
closed suction system, do not place the airway adapter between the
suction catheter and endotracheal tube. This is to ensure that the airway
adapter does not interfere with the functioning of the suction catheter.
WARNING Do not cut or remove any part of the sampling line. Cutting the
sampling line could lead to erroneous readings.
WARNING Inaccurate measurement or equipment malfunction risk. If too
much moisture enters the sampling line (e.g., from ambient humidity or
breathing unusually humid air), the message "Purging filter line" will appear
in the Device Status area. If the sampling line cannot be cleared, the
message "Occlusion in gas line" will appear. Replace the sampling line
when this message appears.
WARNING The sampling line might ignite in the presence of O2 when
directly exposed to lasers or high heat. When performing head and neck
procedures involving lasers or high heat, use with caution to prevent
combustion of the sampling line or surrounding surgical drapes.
CAUTION Only use Welch Allyn-approved CO2 sampling lines to ensure
the monitor functions properly.
CAUTION Microstream CO2 sampling lines are designed for single patient
use and are not to be reprocessed. To prevent damage to the monitor, do
not attempt to clean, disinfect, or blow out the sampling line.
CAUTION Dispose of Microstream CO2 sampling lines according to
standard operating procedures or local regulations.
