<xs:documentation>Reflex Tests

The acoustic reflex is a contraction of two middle ear muscles, named the stapedius and tensor tympani muscles. The muscle contraction is a normal bilateral response to acoustic or other eliciting stimuli, (which is not necessarily bilateral). The amount of contraction and subsequent acoustic reflex decay are measured by immitance audiometry.

The reflex is commonly described as ipsilateral or contralateral depending on which side the response is observed relative to the stimulus.

Usually manual inspection of the recorded response is required to verify that a reflex response has been recorded as normal breathing can cause artefact on the test recordings.
Generally there are 3 tests undertaken using the acoustic reflex response, which are:
1) Normal reflex test
2) Reflex decay test
3) Reflex latency test


1) Normal reflex test
Changes in the immitance of the ear are monitored as a tonal or noise stimuli is presented which elicits an acoustic reflex. The test establishes the lowest sound level that elicits a reliable acoustic reflex response which is seen as a measurable change in acoustic immitance.

As the acoustic reflex is a bilateral response we can stimulate either ear and record a response from the same or opposite ear.

The stimulus can be presented in the same ear as the immitance recording and this is called an ipsilateral reflex. Alternatively the immitance can be recorded in the opposite ear to the stimulus and this is called a contralateral reflex. Ipsilateral and contralateral reflexes test different neural pathways.

For clarity the definitions used are detailed below.

Contra Reflex Measurement (Right):
+ Probe in: Right ear
+ Stimuli in: Left ear
+Reflex result are saved for: Right ear

Contra Reflex Measurement (Left):
+Probe in: Left ear
+Stimuli in: Right ear

+Reflex result are saved for: Right ear

IPSI Reflex Measurement (Left):
+Probe in: Left ear
+Stimuli in: Left ear
+Reflex result are saved for: Left ear

Ref: Pg 207 Katz


2) Reflex Decay test
Acoustic reflex decay or adaptation, is the reduction in the magnitude of the acoustic reflex response during the presentation of a sustained stimulus. (pg 220 Katz)

Test frequencies tend to be 500Hz and 1000Hz as the reflex tends to naturally rapidly decay at high frequencies.

A reflex is said to decay if it falls to 50% or less of its original value in the 10 or 30 second stimulus time.

Abnormally rapid reflex decay is associated with retrocochlear hearing loss.


This curve illustrates the normal situation where the decay value is negative. The formula used for calculating the decay is

Y2 - Y1
_______
Decay = Y1 . 100 percent. Range [0..100] percent.


3) Reflex Latency test
Acoustic reflex latency refers to how long it takes for the acoustic reflex to occur after the stimulus is presented. The delay is measured from the onset of the stimulus until the beginning of the reflex response. (pg 223 Katz). Generally taken as the time it takes after the stimulus is presented for the immitance change to rise to 10% of it’s eventual value.

The latency period tends to be substantially increased in retrocochlear hearing losses.

The number of reflex tests were capped at 16 prior to format 501.  In order to provide backwards compatibility, the following logic will be followed
Convert all results, not exceeding more than 16, any ReflexTests over this number will be dropped.  Convert with the following preferred order
Group 1

<xs:documentation>Eustachian Tube Test (Intact ear drum)

The principle of this test is to record a maximum admittance point and if it is recorded at a significantly negative pressure to continue the test. The patient is then asked to try to force open the Eustachian tube by yawning, swallowing or holding the nose and blowing. A second maximum admittance is then recorded. A normal outcome would be for the second maximum admittance to be recorded closer to 0daPa. Only peak admittance volume is stored for each test. Ref Katz pg. 183

The result of the test  / The movement of the max point from one sweep to another indicates the
pressure change in the middle ear. Maximum admittance is assumed to happen when the applied pressure equals the internal pressure in the middle ear.  Overview and principles of Acoustic.  Ref Katz pg. 176

<xs:documentation>Supplementary data is data supplied by a Noah compatible application that does not follow a HIMSA published standard.  The Supplementary data is included in conjunction with the HIMSA defined data standard – the data will be alongside the well-established HIMSA standards.  For readers that are knowledgeable with the past “Public Extension” concept that Noah originally used with C header file based standards, this idea is similar in nature.

What is the need for supplementary data?

This general idea was originally suggested by a current HIMSA measurement equipment member company. 

Despite HIMSA’s best intentions it is unrealistic that the HIMSA defined data standards can be updated as quickly as desired by another member company.  HIMSA is actively trying to create a system where data standards can be updated in a more flexible manner but there will still be times where HIMSA cannot publish an updated version quickly enough due to technical issues or it could be that there is not good consensus with other member companies on a particular topic.

If data is stored as supplementary data then there is an easier to use option for the member to include the data so that other HIMSA member companies may make use of the data until it may be possible that the data structure be placed in the official HIMSA standard.

At first it may seem that HIMSA is suggesting a step backwards in data standardization but this is not the case.  HIMSA believes that it will only make Noah easier to work with for member companies and in the long run provide HIMSA with more data information that could be candidates for standardization.

What will HIMSA have for requirements?

+The intention for saving the data in this area is to share it to other members that may wish to use it.  If the data is proprietary or is secret in some way, do not store the data here.

+Supplementary data must be stored in an XML format.

+The data must include a version number, if the member creating the data changes the format then the version of the format must change as well

+If a new version is created the member company is required to notify HIMSA of the changes

+The member company creating supplementary data recognizes that HIMSA will most likely review the supplementary data format for possible inclusion in a future HIMSA standard.

What will HIMSA ask for but not have as a requirement?

+Supplementary will be defined by a schema (.XSD) file, if not then documentation must be available to HIMSA member companies requesting it. 

+If a HIMSA standard is eventually updated to include the data that used to be stored in supplementary data HIMSA will strongly encourage member companies to move towards utilizing the updated public data standard.


What can the member companies (creators of data) expect?

+If a Noah runtime data converter is translating data from one format to another it will not perform any conversion on supplementary data, it will simply pass it along in the existing format.  Please note that this will only function on data standards 502 and newer.  This means that software trying to utilize older format (e.g. format 200) will not be able to receive this data.

As the acoustic reflex is a bilateral response we can stimulate either ear and record a response from the same or opposite ear.

The stimulus can be presented in the same ear as the immitance recording and this is called an ipsilateral reflex. Alternatively the immitance can be recorded in the opposite ear to the stimulus and this is called a contralateral reflex. Ipsilateral and contralateral reflexes test different neural pathways.

For clarity the definitions used are detailed below.

2) Reflex Decay test
Acoustic reflex decay or adaptation, is the reduction in the magnitude of the acoustic reflex response during the presentation of a sustained stimulus. (pg 220 Katz)

Test frequencies tend to be 500Hz and 1000Hz as the reflex tends to naturally rapidly decay at high frequencies.

A reflex is said to decay if it falls to 50% or less of its original value in the 10 or 30 second stimulus time.

Abnormally rapid reflex decay is associated with retrocochlear hearing loss.


This curve illustrates the normal situation where the decay value is negative. The formula used for calculating the decay is

Y2 - Y1
_______
Decay = Y1 . 100 percent. Range [0..100] percent.


3) Reflex Latency test
Acoustic reflex latency refers to how long it takes for the acoustic reflex to occur after the stimulus is presented. The delay is measured from the onset of the stimulus until the beginning of the reflex response. (pg 223 Katz). Generally taken as the time it takes after the stimulus is presented for the immitance change to rise to 10% of it’s eventual value.

The latency period tends to be substantially increased in retrocochlear hearing losses.

<xs:documentation>Reflex Tests

The acoustic reflex is a contraction of two middle ear muscles, named the stapedius and tensor tympani muscles. The muscle contraction is a normal bilateral response to acoustic or other eliciting stimuli, (which is not necessarily bilateral). The amount of contraction and subsequent acoustic reflex decay are measured by immitance audiometry.

The reflex is commonly described as ipsilateral or contralateral depending on which side the response is observed relative to the stimulus.

Usually manual inspection of the recorded response is required to verify that a reflex response has been recorded as normal breathing can cause artefact on the test recordings.
Generally there are 3 tests undertaken using the acoustic reflex response, which are:
1) Normal reflex test
2) Reflex decay test
3) Reflex latency test


1) Normal reflex test
Changes in the immitance of the ear are monitored as a tonal or noise stimuli is presented which elicits an acoustic reflex. The test establishes the lowest sound level that elicits a reliable acoustic reflex response which is seen as a measurable change in acoustic immitance.

Eustachian Tube Test (Intact ear drum)

The principle of this test is to record a maximum admittance point and if it is recorded at a significantly negative pressure to continue the test. The patient is then asked to try to force open the Eustachian tube by yawning, swallowing or holding the nose and blowing. A second maximum admittance is then recorded. A normal outcome would be for the second maximum admittance to be recorded closer to 0daPa. Only peak admittance volume is stored for each test. Ref Katz pg. 183

The result of the test  / The movement of the max point from one sweep to another indicates the
pressure change in the middle ear. Maximum admittance is assumed to happen when the applied pressure equals the internal pressure in the middle ear.  Overview and principles of Acoustic.  Ref Katz pg. 176

Supplementary data is data supplied by a Noah compatible application that does not follow a HIMSA published standard.  The Supplementary data is included in conjunction with the HIMSA defined data standard – the data will be alongside the well-established HIMSA standards.  For readers that are knowledgeable with the past “Public Extension” concept that Noah originally used with C header file based standards, this idea is similar in nature.

What is the need for supplementary data?

This general idea was originally suggested by a current HIMSA measurement equipment member company. 

Despite HIMSA’s best intentions it is unrealistic that the HIMSA defined data standards can be updated as quickly as desired by another member company.  HIMSA is actively trying to create a system where data standards can be updated in a more flexible manner but there will still be times where HIMSA cannot publish an updated version quickly enough due to technical issues or it could be that there is not good consensus with other member companies on a particular topic.

If data is stored as supplementary data then there is an easier to use option for the member to include the data so that other HIMSA member companies may make use of the data until it may be possible that the data structure be placed in the official HIMSA standard.

At first it may seem that HIMSA is suggesting a step backwards in data standardization but this is not the case.  HIMSA believes that it will only make Noah easier to work with for member companies and in the long run provide HIMSA with more data information that could be candidates for standardization.

What will HIMSA have for requirements?

+The intention for saving the data in this area is to share it to other members that may wish to use it.  If the data is proprietary or is secret in some way, do not store the data here.

+Supplementary data must be stored in an XML format.

+The data must include a version number, if the member creating the data changes the format then the version of the format must change as well

+If a new version is created the member company is required to notify HIMSA of the changes

+The member company creating supplementary data recognizes that HIMSA will most likely review the supplementary data format for possible inclusion in a future HIMSA standard.

What will HIMSA ask for but not have as a requirement?

+Supplementary will be defined by a schema (.XSD) file, if not then documentation must be available to HIMSA member companies requesting it. 

+If a HIMSA standard is eventually updated to include the data that used to be stored in supplementary data HIMSA will strongly encourage member companies to move towards utilizing the updated public data standard.


What can the member companies (creators of data) expect?

+If a Noah runtime data converter is translating data from one format to another it will not perform any conversion on supplementary data, it will simply pass it along in the existing format.  Please note that this will only function on data standards 502 and newer.  This means that software trying to utilize older format (e.g. format 200) will not be able to receive this data.

<xs:documentation>canalVolume / The admittance equivalent to the Ear canal volume is conventionally subtracted from measures of total aural admittance to yield an estimate of the middle ear admittance. This is referred to as compensated admittance. Ear canal volumes are in the range of [0.30 .. 1.00] ccm in children and
[0.65 .. 1.75] ccm in adults. Refer [HOCA4] Chapter 20. The volume is given by the formula

Vc = γ . ps . Ca = ρ . c2 . Ca where

+Vc / is the equivalent volume in m3
+γ / is the ratio of specific heat for air at constant pressure to that at constant volume, approximately 1.40.
+ps / is the barometric pressure in Pa, normal pressure 0.1013 MPa.
+ρ / is the ambient density of air in kg/m3, at the temperature and pressure of the measurement
+c / is the speed of sound in m/s at the temperature and pressure of the measurement
+Ca / is the acoustic admittance in m3/Pa
+Note 1 / The ear canal volume equivalent is valid at the probe tone frequency 226 Hz.
+Note 2 / The equivalent volume of air is equal to its physical value for values not exceeding 5 ccm.

canalVolume / The admittance equivalent to the Ear canal volume is conventionally subtracted from measures of total aural admittance to yield an estimate of the middle ear admittance. This is referred to as compensated admittance. Ear canal volumes are in the range of [0.30 .. 1.00] ccm in children and
[0.65 .. 1.75] ccm in adults. Refer [HOCA4] Chapter 20. The volume is given by the formula

Vc = γ . ps . Ca = ρ . c2 . Ca where

+Vc / is the equivalent volume in m3
+γ / is the ratio of specific heat for air at constant pressure to that at constant volume, approximately 1.40.
+ps / is the barometric pressure in Pa, normal pressure 0.1013 MPa.
+ρ / is the ambient density of air in kg/m3, at the temperature and pressure of the measurement
+c / is the speed of sound in m/s at the temperature and pressure of the measurement
+Ca / is the acoustic admittance in m3/Pa
+Note 1 / The ear canal volume equivalent is valid at the probe tone frequency 226 Hz.

Please note that this element will not be converted down to format 100 if requested by another Noah compatible software program.  This is due to the fact that two different versions of format 100 Impedance exist and the safest action is to not pass this element back to a module wishing to read in format 100.  Additionally, another software program reading this test should not find this data missing as critical.

The admittance Curve depicts the modulus recording of the admittance, i.e. the length of a complex value, calculated by using Pythagoras´ sentence. In this
structure, both the real and the imaginary part of the value or the value is saved, but for practical purposes, the admittance can be considered 90 degrees out of
phase (real part approximately zero) at the Max. admittance point. This rule applies only for probe frequencies near 220 Hz e.g. 226 Hz.

The application saving the data which comes from an automated solution (gathering all data from the device) is assumed to save data via the Measured choice and provide the G and B values.  Y can later be caluculated by any applicaiton reading the data.

In format 500 this value is formatted depending on the unit_type.  Format 500 defined this element as an integer with a multiplier (a carryover from the C header format 100).  Format 501 defines this field as a decimal value so the converter will follow the below formula when the runtime converter is called.

+ If MilliLiter is the unit then round up the value so that it has 2 decimal values, multiply by 100

+ If Degree is the unit then round up the value so that it has 1 decimal value, multiply by 10

<xs:documentation>canalVolume /  Ear canal volumes are in the range of [0.30 .. 1.00] ccm in children and
[0.65 .. 1.75] ccm in adults. Katz pg 180.

The admittance equivalent to the Ear canal volume is conventionally subtracted from measures of total aural admittance to yield an estimate of the middle ear admittance. This is referred to as compensated admittance.

The volume is given by the formula

Ve = γ . ps . Ca = ρ . c2 . Ca = γ . ps . Ya/(2 . pi . f)

+Ve / is the equivalent volume in m3
+γ / is the ratio of specific heat for air at constant pressure to that at constant volume, approximately 1.40.
+ps / is the barometric pressure in Pa, normal pressure 0.1013 MPa.
+ρ / is the ambient density of air in kg/m3, at the temperature and pressure of the measurement
+c / is the speed of sound in m/s at the temperature and pressure of the measurement
+Ca / is the acoustic compliance in m3/Pa
+ Ya / is the magnitude of the acoustic admittance in m3/(Pa⋅s)
+ f / is the probetone frequency in Hz

In normal used units (Ve in ml, Ya in mmho and f in Hz) this can be approximated as:
Ve [ml] =  Ya . f / 226

+Note 1 / The ear canal volume equivalent is valid at the probe tone frequency 226 Hz.

canalVolume /  Ear canal volumes are in the range of [0.30 .. 1.00] ccm in children and
[0.65 .. 1.75] ccm in adults. Katz pg 180.

The admittance equivalent to the Ear canal volume is conventionally subtracted from measures of total aural admittance to yield an estimate of the middle ear admittance. This is referred to as compensated admittance.

The volume is given by the formula

Ve = γ . ps . Ca = ρ . c2 . Ca = γ . ps . Ya/(2 . pi . f)

+Ve / is the equivalent volume in m3
+γ / is the ratio of specific heat for air at constant pressure to that at constant volume, approximately 1.40.
+ps / is the barometric pressure in Pa, normal pressure 0.1013 MPa.
+ρ / is the ambient density of air in kg/m3, at the temperature and pressure of the measurement
+c / is the speed of sound in m/s at the temperature and pressure of the measurement
+Ca / is the acoustic compliance in m3/Pa
+ Ya / is the magnitude of the acoustic admittance in m3/(Pa⋅s)
+ f / is the probetone frequency in Hz

In normal used units (Ve in ml, Ya in mmho and f in Hz) this can be approximated as:
Ve [ml] =  Ya . f / 226

+Note 1 / The ear canal volume equivalent is valid at the probe tone frequency 226 Hz.
+Note 2 / The equivalent volume of air is equal to its physical value for values not exceeding 5 ccm.
