cooling of the blood. As the cold/cooled fluid is recirculated the
thermodilution curve does not return to its baseline value. The Tail fitting
range allows the user to define a portion of the downslope of the
recorded thermodilution curve from which an exponential curve is
calculated and extrapolated to a baseline. The portion of the downslope
used in this calculation is specified as a percentage of the curve full
height.
The Cardiac Output Module should be used with the latest version of
Chart. Click here for the latest Chart Update for Windows.
The module calculates:
• cardiac output in mL/min
• baseline temperature
• area under the thermodilution curve
• baseline slope correction
The baseline temperature is important in calculating CO and is calculated
for each thermodilution curve created and analyzed. The user in selecting
the curve is also required to define a period of time prior to the
thermodilution curve for the module to determine baseline temperature.
Two parameters are required from the user:
It also adds values to the Data Pad from which data can be exported to
other applications.
1. The Onset time defines the period of time there is beginning to be a
temperature change (the data in this period will not be used for the
Contact baseline calculation).

The module includes three main dialog windows:
1. Cardiac Output Window
2. Cardiac Output Settings
3. Set Baseline Correction
1. Cardiac Output Window
2. The user sets the time interval for baseline temperature determination
in the Calculate baseline from text box. The module will calculate the
baseline over this time interval, with the period selected ending at the
start of the onset period (see Cardiac Output window above).
3. Set Baseline Correction
Any baseline drift can also be corrected by selecting baseline data and
choosing Set Baseline Correction from the Cardiac Output menu.
Selecting OK will automatically insert the correction factor in the CO
calculation, or it can be turned on or off in the Settings dialog box by
checking or unchecking the Baseline slope correction text box.
The capture option in the Setting dialog box allows the user to mark the
selected thermodilution curve with the CO values as well as automatically
adding the calculated values for each thermodilution curve to the
Data Pad.

PowerLab
DMT Normalization Module for Chart
DMT Normalization Module
The MLS065 DMT Normalization Module provides an easy method for the
calculation of optimal pretension conditions for microvascular or any
small tubular tissue research. The DMT Normalization Module is for use
with PowerLab, Chart and DMT Wire Myographs.
The DMT Normalization Module should be used with the latest version of
Chart. Click here for the latest Chart Update for Windows.
The module:
• Automatically calculates tissue length
• Provides online and offline determination of effective pressure
• Calculates the pre-tension (micrometer setting)
for normalization
A graph of internal circumference
versus resting wall tension is
created with each stepwise
distension, with the module
ending once the effective pressure
exceeds 100 mmHg (13.3 kPa). An
exponential curve is then fitted to
the internal circumference
pressure data and, using Laplace's
equation, the point on the curve corresponding to 100 mmHg is
determined and denoted IC100. From the IC100 a value IC1 is calculated
(0.9 x IC100) which the module then uses to calculate the micrometer
setting which sets the internal circumference to this pressure. The
module has been set with a default of 0.9 (rat mesenteric vessels) this
ratio (IC1/IC100) should be determined for different tissue types.
The rationale and theory behind normalizing elastic tissues such as
microvessels has been extensively investigated by Professor Michael

pre-tension conditions for the tissue being studied.
It is therefore important to define the experimental conditions prior to
conducting investigations into the properties of elastic tissues.
The normalization procedure is performed by distending the vessel
stepwise and measuring sets of micrometer readings whilst recording the
developed force using PowerLab and Chart. The DMT Normalization
Module calculates the internal circumference from the measured distance
between the wires, known diameter of the wire and length of tissue used.
The length of the tissue is determined using a calibrated eyepiece and
microscope. Wall tension is the measured force divided by the wall length
from which effective pressure is calculated. Effective pressure is an
estimate of the pressure which would be necessary to extend the vessel
to the measured internal circumference.

Operation
The 75 Hz oscillator supplies a near square wave, low-impedance, lowvoltage (22 mVrms) signal to an electrode on one finger of the subject. If
the skin has a measurable conductance, current flows from the electrode
on the other finger back into the very low impedance input of the
transimpedance amplifier. The current is then converted to a voltage
signal. The current will change as the autonomic reflexes change the
skin’s conductivity.
• Do not use recording gel with the electrodes. This will tend to give
higher basal readings as skin resistance is lowered by gel.
• Avoid measuring skin conductance if the subject is perspiring
excessively at rest.
The ML116 GSR Amp is supplied completed with the following:

Theory of Operation
The Bridge Pod provides excitation and signal amplification for straingauge transducers in a single device. An excitation voltage of 2.5 V is
applied to the transducer with the transducer output signal being
differentially amplified and then low pass filtered to remove high

ML312 T Type Pod
Theory of Operation
EC1 77-0040 ML312 T Type Pod
The thermocouple voltage signal is amplified to produce 10 mV/°C @
25°C. Ice Point Reference compensation is provided by the direct
measurement of the input connector temperature. The equivalent voltage
is subtracted from the thermocouple voltage to compensate for the
changes in the ambient temperature. Temperature changes are typically
slow and filtering is provided by a 2 pole 10 Hz Butterworth filter. This
will provide adequate filtering from mains power supply and allow fast
temperature transients to be monitored.
Note: The output of the Pod is not linearized.
Stacking and Unstacking Pods
Pods stack by clicking into place on top of each other. To separate stacked
Pods, push the top Pod towards the back and then pull them apart from
the back. See picture on right.
