Frequently Asked Questions

What hemodynamic parameters does the LiDCOrapid display?

The LiDCOrapid displays the following parameters:

  • Pressures – MAP, Systolic and Diastolic
  • Heart Rate
  • Stroke Volume and Cardiac Output (Scaled or Actual)
  • Dynamic Preload parameters – Pulse Pressure Variation (PPV) and Stroke Volume Variation (SVV)
  • User selected event response window

Can I configure the display?

The screen is organised in a visually intuitive and informative manner to provide early warning of hemodynamic change, predicted fluid responsiveness and actual response to a therapeutic intervention

iconUsing this icon, you can change which parameters are displayed, the averaging period for numeric values and choose between absolute or indexed values.

How do I get started?

Insert a LiDCOsmart Card, connect a blood pressure monitor, enter patient demographics and press the Rapid button. It takes about 1 minute to setup

How is Pulse Power Analysis different from Pulse Contour?

Pulse Power analysis used by the PulseCO algorithm, uses the entire BP waveform, not just the area under the systolic portion. The waveform is transformed from pressure to volume for analysis since the desired value is Stroke Volume. The use of Autocorrelation then finds the proportional power in the volume waveform independent of the wave shape.

Which patients is it applicable?

The LiDCOrapid can be used in any patient with a continuous blood pressure waveform generated from either an arterial transducer or non-invasive sensor.
The LiDCOrapid is designed to provide fast effective advanced hemodynamic information to assist with stroke volume optimisation, fluid or drug interventions in the peri-operative setting.

Can I use it in pediatrics?

The LiDCOrapid is not approved for use in pediatric patients at this time.

What are the contra-indications?

Peripheral vascular disease
Aortic regurgitation

Can I use it in patients with arrhythmia?

Yes – the PulseCO algorithm will continue to derive HR, SV and CO though there may be an increased frequency of data that cannot be analysed. SV response can still be used effectively for fluid management.

LiDCO recommends that the SV numeric display use increased averaging times of at least 20 or perhaps even 30 seconds SVV/PPV is not useful with arrhythmias that result in heart rate variation >5-10%.

If the arrhythmia is intermittent and/or infrequent then SVV/PPV can be used during times of normal sinus rhythm.
