Demand and Non-Demand Pacing

 

Demand and Non-Demand Pacing

 

  • The LIFEPAK - 15 monitor/defibrillator can be used for either demand or non-demand (asynchronous or "fixed rate") pacing.
  • Demand mode is used for most patients. In demand mode, the LIFEPAK 15 pacemaker inhibits pacing output when it “senses” the patient’s own beats (intrinsic QRSs).
  • In demand mode, if the ECG SIZE is set too low to detect the patient’s beats, or if an ECG lead becomes detached so that the ECG rhythm is not present, the pacemaker generates pacing pulses asynchronously.
  • This means that the pacemaker generates pacing pulses at the selected rate regardless of the patient’s ECG rhythm.
  • Non-demand mode can be selected if noise or artifact interferes with proper sensing of QRS complexes.
  • Press OPTIONS to access non-demand mode.
  • Non-invasive Pacing Procedure
  • ECG monitoring during pacing is performed with the ECG electrodes and patient ECG cable.
  • Therapy electrodes are not capable of monitoring ECG and delivering pacing current at the same time.
  • Be sure to place the QUIK-COMBO therapy electrodes in the proper locations. Improper placement of the electrodes may make a difference in the capture threshold. For example, if the electrode placement is reversed, more pacing current may be needed to achieve capture.
  • WARNING POSSIBLE INTERRUPTION OF THERAPY
  • Observe the patient continuously while the pacemaker is in use. Patient response to pacing therapy (for example, capture threshold) may change over time.
