Philips Impedance Cardiography (ICG) continuously measures hemodynamic parameters without the associated risks of traditional invasive methods.
The Philips ICG measurement is ideal for hemodynamic evaluation of adult patients in:
- Emergency departments
- Step-down units
- Special procedure areas
Impedance cardiography is designed for assessment and management of congestive heart failure, hypertension, and pacemaker patients. It is also appropriate for select ICU patients.
Designed for non-invasive, safe, and timely measurements
- Portable, weighing only 2.2 kg (4.9 lbs)
- Sharp 12 cm (4.96") color display
- Advanced patient-specific algorithm accounts for gender, age, and body surface area in calculating hemodynamic values
- Two-hour battery for emergency and transport support
- Navigation wheel operates much like a mouse
- Built-in recorder/printer for recording waveforms and documenting trends
- Signal Quality Indicator for validation of ICG waveforms at a glance
- 12 hemodynamic parameters for comprehensive assessment including:
- Thoracic Fluid Content (TFC)
- Accelerated Cardiac Index (ACI)
- Stroke Volume (SV)
- Cardiac Output (CO)
- Systemic Vascular Resistance (SVR)
- VueLink connection to Philips IntelliVue, CMS, and V24 and V26 patient monitors
The technology behind ICG
Impedance cardiography (ICG) is a safe, non-invasive method to measure a patient's hemodynamic status. The ICG waveform is generated by thoracic electrical bioimpedance (TEB) technology, which measures the level of change in impedance in the thoracic fluid. Four small sensors send and receive a low amplitude electrical current through the thorax to detect the level of change in resistance in the thoracic fluid. With each cardiac cycle, fluid levels change, which affects the impedance to the electrical signal transmitted by the sensors.
Using ICG for the appropriate patient population
The ICG measurement is designed for assessment of most adult patients – height 122-229 cm (4´-7´6˝) and weight 30-159 kg (67-350 lb) – but may demonstrate reduced accuracy when patients present with the following conditions or anomalies:
- Aortic valve regurgitation
- Minute ventilation sensor function pacemakers
- Connection to a cardiopulmonary bypass machine
- Sustained arrhythmias
- Connection to an intra-aortic balloon pump or chest tubes
Connection to a respiratory ventilator - Congenital heart defects
- Pericardial effusion
- Severe hypertension (MAP > 130 mm Hg)
- Septic shock
- Severe anemia
