One aspect in the
measurement of ventricular volume using the conductance catheter
technique is the assessment of parallel electrical conductivity of
structures extrinsic to the ventricular blood pool. Because it is
sometimes necessary to make volume measurements during ventilation or
spontaneous respiration, the extent to which parallel conductance may
vary with lung insufflation was investigated. Anesthetized pigs
(11-15 kg) were ventilated and instrumented with both left (LV)
and right ventricular (RV) conductance and pressure-tip catheters and
end-hole catheters for injection of hypertonic saline into the inferior
vena cava and pulmonary artery. Data were recorded during ventilation
with tidal volumes of 10 and 20 ml/kg, and the associated fluctuations
to LV and RV end-diastolic (EDV) and stroke (SV) volumes were measured.
With the use of a saline dilution technique, parallel conductance
(V c ) was determined for each
ventricle with the ventilator off and lungs insufflated to 0, 10, and
20 ml/kg. Whereas ventilation caused marked oscillations in LV and RV
EDV and SV, these variations could not be attributed to
V c , which remained statistically
unchanged from their baseline values of 34.1 ± 3.1 in the LV and
31.1 ± 4.4 in the RV. These results indicate that the fluctuations
that occur in conductance catheter-derived LV and RV volume signals
with ventilation are not caused by any significant changes to parallel
conductance.
