7-2 Physiological Signal
9. Display effect of respiratory curve depends on the patient
breathing status. While a very slow or smooth breathing may
lead to an inapparent respiratory curve, breathing in a large
amplitude may cause an incomplete display of the respiratory
curve.
10. Display effect is linked to the connected parts of the body.
Generally, signals by connecting to limbs are stronger than by
connecting to the chest.
When abnormality is detected in physio trace, please check if ECG leads are
properly connected with the system.
