Other inspections

It is a test to evaluate how it is affected by hypertension and diabetes by taking a picture of the fundus, the only site in the human body where the small aorta can be observed directly.

Please remove your glasses. You can leave your contact lens on it. I don't have to pay particular attention to anything else. There is no pain at all, but I feel a little dazzling because the camera flash shines in front of me.
If you use pupils, it will be quite dazzling, but it will not be used in regular inspections, so it will feel dazzling for a moment when shooting.

ABI (blood pressure ratio between ankle and upper arm) and PWV (pulse wave propagation speed) are collectively called blood pressure pulse wave tests.
ABI (Ankle-Brachial Index) measures the ratio of blood pressure between the ankle and upper arm, and shows the degree of blood vessel clogging by numbers. In the case of healthy people, the blood pressure of the ankle is usually higher than the blood pressure of the upper arm, but if the arteries of the foot are clogged by lipids, the blood flow will be worse, lower than the blood pressure of the upper arm, and the value of ABI will be lower.
PWV (Pulse Wave Velocity) is the velocity of pulse Wave Velocity (Pulse Wave Velocity) is the velocity generated by blood extruded from the heart to reach hands and feet through the heart. The harder the blood vessels, the faster the speed.

ABI is a test to check the condition of blood vessels.
PWV is a test to check the hardness of blood vessels. The normal value varies depending on age, but the harder the value is, the larger the value.
ABI and PWV can be comprehensively evaluated from the waveform obtained at the same time.

Those who are suspected of arteriosclerosis. If you have hyperlipidemia, hypertension, obesity, smoking, cold, numbness, etc., arteriosclerosis may already progress.

The inspection time is only about 5 minutes. The test itself is done in the same way as measuring blood pressure by wrapping a sphygmomanometer around both hands and both ankles.
There is little pain, but in the case of high blood pressure, there is a little feeling of pressure due to strong pressure.
You can inspect thin clothes without taking them off.
Arrhythmia with heart fibrillation may not produce correct results.

CVRR： Coefficient of Variation of R-R range = ECG R-R interval variation coefficient

Heart rate fluctuations are considered to be correct on a regular basis, but even if it is a streak, the heart rate may have fine fluctuations. This "float" is generally due to respiratory arrhythmias (R-R interval: the interval between pulse and pulse decreases to intake and increases during exhalation).
“Swaying” decreases or disappears in a state where autonomic nervous function is impaired. Because the R-R interval at rest is suppressed by atropine and does not change in Propla Nord, it is mainly due to cardiac parasympathetic nerve control, and the CV value (variability coefficient) is considered to reflect the state of parasympathetic nervous system control. The parasympathetic nerve is one of the autonomic nerves. Therefore, it is performed for the purpose of understanding the autonomic nervous function. Adaptation is a disease that is considered to have autonomic nervous system disorders ( orthostatic hypotension, diabetes, Parkinson's disease, cerebrovascular disorder), but cannot be done if there is arrhythmia or if rest cannot be maintained.

Basically, the ECG is recorded to see changes in the R-R interval. An electrocardiogram is amplified and recorded waveforms of the potential generated as the core moves, and electrodes are attached to obtain this potential from the living body. Specifically, large wash scissors-like electrodes are attached to four locations, both wrists and two legs, and suction cup-like electrodes are attached to six locations on the chest wall. Wrap the sleeves of the jacket so that the wrist comes out, the hem so that the ankle comes out, and the jacket (with the underwear) so that the chest comes out. The electrode can be easily attached and can be recorded as soon as it is attached. It is done after a certain period of time in rest. The heart rate is measured by 100 beats at rest and deep breathing to check for changes in R-R intervals. In the test at rest, do not breath deep and do not sigh. Do not sigh in a test during deep breath.

Basically, it is the same as the rest electrocardiogram test.
The wrist, ankle, and chest are exposed and inspected.
It's enough to just roll it up without undressing.
Please come in clothes that are easy to take off or wear, or wear clothes that are easy to roll up. If you are wearing stockings, please take them off.

PSG： Polysomnography

For the purpose of evaluating sleep-related disorders, it is divided into "simple PSG test" and "full PSG test" according to the type of sensor to be attached.

Wear airflow sensors in the nose and percutaneous oxygen saturation (SPO2) on the fingers to see how long you have apnea (stop breathing) and low breathing (light breathing) during night sleep.
The apnea hypopnea index (AHI) is calculated based on a comprehensive assessment of SPO2 decline. Air current stoppage of 10 seconds or more is apnea, and sleep apnea Syndrome (SAS) if apnea is 30 times or more per night or 5 times or more per hour.
SAS is said to be an independent risk factor for ischemic stroke because it causes a decrease in SPO2 and an increase in blood pressure.

There are no special precautions before the test, but when sleeping at night, the sensors attached to the body often come off due to the movement of the body. Ensure that the sensor is attached and fixed as much as possible so that the sensor does not come off. Simple PSG is basically a test only for inpatients at our hospital.

Basically, after performing a simple PSG, many AHI is performed for those who are judged to be mild to moderate, and more sensors are installed and inspected than simple PSG. It is intended to detect respiratory disorders during night sleep, sleep-related disorders, and sleep-related motor disorders. More detailed evaluation is possible than simple PSG.

EEG is attached to the head, an electrocardiogram sensor, a chest breathing sensor, an abdominal breathing sensor, an electrocardiogram sensor is attached to the feet, and a percutaneous oxygen saturation sensor is attached to the fingers. In that state, they go to bed at night and evaluate respiratory disorders during sleep.

As with the simple PSG, care must be taken to ensure that the sensors worn during sleep do not come off.
You need to be hospitalized for at least one night because you are sleeping at night.
The test is finished when you wake up in the morning and wake up.
There are no restrictions on behavior on the day before or on the day of the inspection.

It measures the amount and momentum of breath by inhaling, exhaling, and exhaling vigorously to check the function of the lungs.
"Lung activity" measures the capacity of the lungs that can be absorbed and vomit.
"Effortal pulmonary activity" Measure how vigorously you breathe up to the maximum.
The inspection time is about 15 minutes.

Isn't the capacity of the lungs low? → Pneumonia, aeropulmonary, pulmonary edema
Is the passage of breath (airway) narrow? → Bronchial asthma, bronchitis
Isn't your lungs hard? → Interstitial pneumonia, pneumonary, pulmonary fibrosis, etc.
Are there any weakness in the muscles that breathe or abnormal nerves? → Severe muscle amorphous, amyotrophic lateral sclerosis
Tests are performed when respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD), or emphysema are suspected.

You may have a meal, but please avoid the meal immediately before, as it may be difficult at the time of the test if you eat or are full.
Please come in clothes that are not tightened, as you will breathe and exhale greatly.
The results of lung function tests vary depending on the efforts of the person being tested. It's hard to tell if it's the maximum effort just by one result, so do the same several times and choose the best result.

The function of the autonomic nervous system allows the human body to send blood to the whole body against gravity even when standing or sitting. If an abnormal regulation of the autonomic nervous system occurs, blood pressure is not adjusted when it rises, and blood flow to the brain temporarily decreases and faints may occur.
A head-up tilt test is a test in which the body is passively raised and the accompanying changes in pulse and blood pressure and the appearance of symptoms are confirmed.

It is mainly for those who have symptoms of fainting. In addition, neurological diseases such as Parkinson's disease may have abnormal nerve regulation, so tests may be performed.

You will be placed on your back on a dedicated bed, and you will be tested while measuring your electrocardiogram and blood pressure. During the inspection, the bed may be moved so that it is standing or horizontal, but please leave it to the movement of the bed.
One of the objectives of this test is to check for symptoms during the test. If you experience symptoms such as mood discomfort or nausea during the test, do not endure it and immediately inform your doctor or laboratory staff. In addition, for safety, the body will be fixed with a belt during the test.
Do not eat for 2 hours before the test. Test results may be affected. In addition, please check with family doctor about oral medicine before examination.

The balance of the body is unconsciously maintained by multiple factors, such as sight, front yard, seminormal system, and reflection system of the spinal cord. However, the body's balance may be lost due to impaired parts related to those balance functions or psychological loads.
The purpose of the test is to measure the shaking of the body (the fluctuation of the center of gravity) and evaluate it objectively.

Tests are conducted mainly on patients who complain about dizziness and flickerness.
It measures how the body shakes while standing, and estimates the location of the disorder that causes the flicker from the way it shakes.

The inspection is performed upright on the measuring device (plate). The measurement is performed for 1 minute (or 30 seconds), respectively, in the open and closed conditions. You may also place a cushion on the plate and stand on it to measure it. In addition, moving the position of the foot on the plate will affect the test results, so be careful not to move the position of the foot during the test.
Even if you are worried about standing, an inspector always accompanies you during the measurement so that you can support your body if it is likely to fall down.
