How is Respiration Rate Monitored?
GE HealthCare bedside patient monitors provide capability to monitor respiration rate during ECG monitoring. Impedance respiration is measured across the thorax and upper abdomen between ECG electrodes. The respiration signal is made by supplying current between the electrodes and by measuring the differential current from the electrodes. The signal measured is the impedance change caused by breathing
Lead Placement options
There are three lead placement options available in GE HealthCare bedside patient monitors. These are Lead I, Lead II and Vector RL-LL .
Lead I
Provides good thoracic (upper chest) breath detection. However, lead I is more susceptible to cardiogenic artifact than the RL-LL vector.
Lead II
Provides good thoracic breath detection and upper abdominal (lower chest) breath detection. However, lead II is more susceptible to both cardiogenic and motion (head, neck, or arm) artifact than the RL-LL vector.
Vector RL-LL
Provides good abdominal breath detection and is not as susceptible to cardiogenic artifact or motion artifact. However, RL-LL is not available with 3-lead placement and with 5-,6- and 10-leadwire electrode placement, the RL electrode should be placed on the fifth intercoastal space on the right side of the chest.
Optimal Sensitivity
Choosing a vector that expands over the abdomen is beneficial for achieving good signal amplitude and high signal to noise ratio with neonates.1 Hence selecting vector RL-LL is preferred for neonates for reaching the highest sensitivity for the respiration rate monitoring.
