What is a capnography monitor?
A capnography monitor is a device that measures carbon
dioxide. The capnography monitor is attached to tubing near
the end of the breathing or tracheostomy tube. Carbon
dioxide measurement is an important part of monitoring lung
function. The carbon dioxide values from the capnography
monitor are often displayed on the bedside monitor.
When is a capnography monitor used?
A capnography monitor is used when the patient's condition
may effect the carbon dioxide levels in the blood. The
capnography monitor is also used to confirm that a breathing
tube is in the pateint's airway.
Does use of a capnography monitor
hurt?
The use of a capnography monitor does not hurt.
How long is a capnography monitor
used?
The capnography monitor is used as long as the patient
requires close monitoring of the carbon dioxide level.
Are there any complications
associated with use of a capnography monitor?
Several factors may cause false readings of the carbon
dioxide level. The capnography monitor has an alarm system
that will signal the nurse or doctor if this happens.
