How to Average Epochs


How to select Epochs

1. Point the mouse in the place you want the beginning of the epoch press the wright button and from the   contextual menu select Epoch 1 sec.  / Epoch 2 Sec., (this refers to epochs of 1 or 2 seconds).

2. In this point will appear the first line and automatically after 1 or 2 seconds (it depends on the option you have chosen).

3. If you want to process the epoch goes to the Analysis Menu > Select epoch option > from the listed epochs select the epochs that weren’t processed with a click. With the left mouse button, press OK button.

.


How to average the epochs

A- First you must select the epochs (as we explained before).

B- Select Analysis Menu > Select Epoch > A dialogue box will be displayed with the epochs listed processed or not.

Select with the mouse the first epoch, press the select button and then select the other, press again the select button.

The epochs you want to average were selected and they have an arrow over the left side. Finally press the OK button and a box will appear with the option to add a name to the new average.

This average will be shown later in the Epochs lists with the name you add.

The difference between 1 and 2 seconds is the Discrimination

That is the inverse of an epoch:

1/1 second = 1 Hertz

1/2 second = 0,5 Hertz

When you discriminate with epochs of 1 second

When you discriminate with epochs of 2 second

From the Select epoch box you will see:

NP: Not processed

FFT: Processed

AVG: Averaged epochs.

In the box you will find this information for each one:

Type

File

Duration

Second

Pixel (Position)

If you want to obtain the average of 4 epochs you must select as we explain before

The program will calculate the FFT (Fast Fourier Transformer) of each one and then will ask you a name of the average, for example

 “AWAKE 1”, normally physicians makes the average in patient condition.

If you see the epoch list, you will see that all selected epochs are named FFT (they are processed with FFT) but you will have too the list of the averaged epochs.

Polysomnography Analysis Explanation


Polysomnography analysis

For the wright use of this menu, it is necessary to know how the software prepares and makes the necessary function to obtain the results in the register analysis.

Tables are generated taking the specific data from the study of the parameters involved. For example the oximetry table is the recollection of this information second to second.

The table is the result of the obtained register and it’s unique for each study, but it can be process with different procedures. For example if a patient has an oximetry value of 40% if the procedure asks to reject this value, in the result of this procedure the value will not appear, but in the table this value will always exist.

Anyway it is possible to edit the tables that has been generated in case you detect a sensor disconnection, etc.

Tables are automatic or manual, the majorities of them are just data collection from the register such as oximetry, cardiac frequency, muscle activity, and are generated automatically.

Tables as Sleep stages or apnea determination can be made manually.

Once you have obtained the tables, results will be process with different procedures.

Procedures are specific for each parameter because a cardiac frequency that could be normal for a newborn could not be for an adult. For this reason the physician will be able to use different procedures to each particular data.

Summary: tables will be shown in a general graphic where all the variables are shown


Procedures

Procedures are different ways to make the analysis of the register, the physician must set up them previously. Procedures are made once and can be modified later to obtain accuracy in the results.

The operator may use different procedures to process a study that matches to the patient characteristics. For example the sleep procedure will be selected according to the patient age.

Different possible procedures exists for each parameters:

1 – Sleep Stages

2 – Apneas/hipopneas

3 – Respiratory Events

4 – Oximetry

5 – Cardiac Events

6 – Microphone

7 – Legs

8 – CPAP

9 – pH

You will be able to create different procedures

The software admits the changes and immediately modifies the existing procedures or generates a new one.

We suggest to asign a name easy to identify for each procedure, for example: apnea procedure for “Adults”, “Newborn” etc.


Automatic Tables

As we explain before, the automatic table is a fast and sure way to join patient data for their analysis using a procedure and obtaining a result or summary.

Tables have collection information and are unique for each patient independent of the procedure later used or done.

You may modify it manually if some periods of the data are not accurate (sensor disconnection, etc.)

It is essential to obtain the tables previously to data processing. To generate the tables it is necessary to point out from which channel the information must be taken. For example, if the EXT1 channel made the oximetry, when you generate the table you must be sure the data of the input channel is the correct.

Available Automatic Tables:

1 – Sleep Stages

You must specify the EEG channel it will be processed automatically trough the FFT and other parameters of spectral power and amplitude, husos, etc.

2 – Nasal Air Flow Nasal

3 – Thorax Frequency

4 – Abdominal Frequency

5 – Oximetry

6 –EKG

7 – Microphone

8 – Legs activity

9 – CPAP

10 – pH

All the tables are generated in one step, using the Swap option.


Manual Tables

There are two manual tables, and it is an easy procedure:

1 – Sleep Stages Tables

2 – Apneas, Hipopneas

In both tables appears a menu join to the register, this menu allows you to select the results of each page. To accelerate the process you may review the register using 12, 16, 20 or more seconds / screen (according to your monitor resolution).

It is interesting to explain the sleep results table.

If you have made an automatic analysis indicating the channel from which you want to make the analysis you will obtain the percents of the different rhythms found in the page for the selected channel.

The results shown are:

-	The selected channel to made the FFT

-	Delta waves percent

-	Theta waves percent

-	Alpha waves percent

-	Beta waves percent

-	Husos in the Sleep

-	Eyes Movements

-	Chin tone in the channel 1

These percents are the results for the selected channel. It does not mean that under the Suggested item the software is giving us a true stage: it depends on the way you set the procedure. This procedure is not simple to configure, it requires time and experience because the different percentages are difficult to determinate.


Video EEG/PSG

Enable Video x Page
Complete Video

You have two options to present the video:

1 – Video per pages

2 – Complete Video

1 – Video per pages.

This Video option is useful when you want to make in synchrony the electroencephalograph events with it; a cursor will show you exactly where the frame is located in the register.

The register review it is possible to be done in a  manual or automatic way, with events velocity when you select the quantity of frames per second to be shown.

The video in the screen in conjunction with the EEG/PSG data in long-time tests makes easier the reviewing.

When you go page Up or page Down in the study pages, the first image of this page is shown automatically, if you want to have a view of the video of the selected page you must follow this steps.

There are different options:

1-1	Run automatically the video

1-2	Stop the video

1-3	Start again

1-4	Select the frames per seconds to be shown

(not the frames/seconds the test was acquiered)

1-5	Go forward or backward with the cursor: to correlate the image with the Eeg data.

1-6	With the slider command you can view the pages in fast way.

1-7	 If you locate the video cursor you get the video image that belong to the selected register position.

1-8	The video image could be reduced to have a better view of the register in complete way.

1-9	Full Screen Video View

2	-  Complete Video:

This is only a video image (non-synchronized) very useful in some pathologies where it is not important to correlate the Eeg with the video, just to observe patient movements, attitudes, etc.

In this video option you may:

-	Run automatically the video

-	Stop the video

-	Start again

-	Select the velocity

Impedance Test

Each channel is tested in reference to the Ground, if an impedance is shown in all electrodes, check the ground electrode.

The impedance is displayed in Kohms.

Impedance higher than 12K is not acceptable to obtain a good register.

When impedance is higher than 12 Kohms, check the electrode r its contact with the patient. If there is no contact with the skin a line will appear instead of a number.

During the impedance test, all the electrodes where tested approximately each 2 seconds.

It is necessary a few seconds to stabilize the test (6-10 seconds), when the system is stable the impedance lectures have minimum variations.

.

Calibration Test

Once you put the electrodes to the patient, it is advisable to do a calibration test before to let the patient go home and to have for sure an optimum register. Plug in the recorder to the computer > select the Tools Menu > and the Calibration Test option.

It is possible to make this Test when the patient return with the Recorder on to test the status of the electrodes and the recorder.

See the explanation on the printing manual to have a more detailed explanation about the connection and the Test..

Collection Test

Has the same procedure of the Calibration Test.

Read Holter

Once the patient returned to the clinic, you must plug in the recorder to the computer.

Select the file >New > fill all the information about the patient > Enter

Here it will appear a window with the information of the electrode inputs of the 8 channels >

Then select the start hour of the register >

Press OK key

Select the Tolls Menu> Read Holter Option >

One window will be display on the screen to select the time of the study.

You can do an ambulatory study between 1 up to 20 hours.

When you pass the information from the Recorder to the computer you can select the time of the information to be pass to the computer, 1, 2, 3, 5 , 8, up to 20 hours.

This could be useful to pass exactly the time you recorded on the recorder and not to lose time passing more time than the necessary.

Delete Holter

Once you pass the information of the recorder to the computer and make the information of the study (be sure before to do this option) you can delete the holter to let it free of information to be able to record another study.

To delete the information select the Tools Menu > Delete Holter option > DELETE button.

If you don’t want to delete in this moment select the Cancel option.
