Impedance respiration
In addition to true breaths, patient motion can also change the impedance of the
chest, and is thus visible in the impedance waveform. Motion artifact can be several
times larger in amplitude than normal breathing.
The following graphic illustrates how motion artifact is reflected in the respiration
waveform:
In this example:
●
1–11 = room-bed identification
●
Smith, Peter = patient’s last name, first name
●
RR/min ( RR/min ) = respiration rate label and unit of
measure
The top row below the RR value 20 shows the waveform
during breathing. At the end of the top row, and during
the entire second row, the waveform shows large artifacts
caused by a moving patient. Patient motion reduces the
RR value reliability, which is indicated by the SQI indicator
having only one filled circle.
Waveform scale is indicated on the top row (in this
example: 2x).
Respiration measurement practicalities
Instruct the patient regarding the following issues. Always consider your hospital
guidelines as well.
●
The respiration sensor should be detached before having a shower. The respiration
patch can be left attached.
￭
After the shower:
♦
Check that the electrodes are properly attached to the skin and that there is
no skin irritation. If the electrodes are no longer properly attached or the
adhesive no longer holds, replace the respiration patch.
♦
Make sure that the respiration patch connector is completely dry before
reconnecting the sensor.
Respiration points to note
●
This equipment is suitable for use in the presence of electrosurgery, as tested
according to IEC 80601-2-49 clause 202.8.102 Electrosurgery interference.
●
Defibrillator discharge may affect the respiration measurement. Defibrillation
recovery time after discharge is ≤15 seconds.
●
Materials used in accessories are not toxic. Accessories do not contain natural
rubber latex.
●
Preferably use the measurement sites as indicated in the instructions delivered
with the respiration patch to ensure reliable and accurate measurement.
