Advice 1: How to determine high or low pressure

Broken blood vessel tone and the impact of adverse external and internal factors often cause "jumps" pressure. And, despite the similarity of some symptoms of the human condition at elevated and reduced pressure have a number of significant differences. It is important to know about them to be able to provide first aid or the time to go to the doctor for the recovery of the cardiovascular system.
Instruction
1
For hypotension characterized by lowering the pressure of 100/65 mm Hg. Depending on the age, these numbers can fluctuate. However, if no tonometer to determine the pressure, pay attention to other symptoms. Although the physiological hypotension may years to flow without any deterioration or changes in health.
2
If every morning starts with poor health, weakness, lethargy, irritability, and during tilting of the bed, dark eyes, most likely, the pressure is lowered. And if in addition to these symptoms I feel that hands and feet are constantly cold, periodically muscle and joint pain, and unpleasant sensations in the heart and shortness of breath, better confirm his suspicions the doctor with the help of tonometer. Do not wait for the manifestations of the pathological hypotension, which can occur suddenly. And it starts with noise in the ears, headache, weakness, nausea, and in some cases ends up fainting and shock.
3
Low blood pressure is more typical for young people, primarily female, thin, gipodinamiya prone to dieting. However, hypotension may be a leading symptom of certain diseases.
4
High pressure is considered, the indicators of which range from 130/90 mm Hg and above. Physiological pressure increase during physical and mental stress does not cause any changes in the health and quickly recovering. More or less its long-term preservation can be in some diseases of the kidneys, endocrine glands, and brain. In this case, hypertension is only a symptom of these diseases.
5
As an independent disease, hypertension appears abruptly and prolonged increase in pressure. So if you suddenly felt unwell, throbbing, oppressive headache in the occipital region, and thus the feeling of nausea, and in front of my eyes floaters, then most likely, the pressure increased. This condition usually persists up to several days and often associated with exposure to adverse factors. In addition to these signs can cause palpitations and heart pain. The disease progresses gradually numbness of the fingers and toes, hot flashes to the head and dizziness, sleep disturbance, fatigue.
6
Despite all the sensations and presumably abnormal pressure, if you feel unwell go to a more accurate examination. It will help to take further the right direction of treatment.

Advice 2: How to define high blood pressure

The power supply system of diesel engines Common Rail is divided into two stages: low and high pressure. And if the first is intended for uninterrupted supply of diesel to the injection pump from the second operation start up and operation of the motor.
You will need
  • - voltmeter,
  • adapter with the scanner
  • - pressure gauge at 1450 ATM.
Instruction
1
The end point starts low line high pressure, comprising:
- the fuel high-pressure pump (injection pump) with safety valve,
- the fuel high-pressure accumulator (TAVDA) with gauge and valve regulator;
- motor-injectors, plug-in electronic control unit (ECU);
- connecting tubes.
2
Diesel engine, unlike gasoline, is very sensitive to fuel injection. From the correctness of the set ignition timing depend on the main parameters of the motor (power, consumption of diesel fuel, resource). Change the crankshaft position at which the closure of the valve timing and the fuel injection into the cylinder, at least one risk to the "+" or "-", significantly changes the behavior of the power plant.
3
Specialists, fuel equipment, always with special responsibility came to installing fuel pump (fuel pump high pressure), meticulously comparing the torque of the drive clutch in accordance with the angle of start of injection. The Common Rail system has nullified all the efforts of the mechanics, with a mandate to monitor the specified parameters to the electronic control unit of the power plant.
4
Now the only problem when installing the injection pump to the engine is the articulation of the elements of the drive coupling. But the electronics tracks not only the time of the injection, she keeps an eye on the formation of high pressure in the fuel accumulator, on the left side of which is fixed a suitable sensor, sending signals to the ECU.
5
To verify that the system power and measure how high pressure it is necessary to conduct diagnosis. But what about those drivers who have motor refused to run, and the electrician we still have some way to get. To buy a scanner that costs ten thousand roubles and above, and carry it with you? Or buy a manometer and a half thousand atmospheres, the price of which is not below the adapter, turn the adapter to measure high pressure?
6
If you study carefully the documentation on the Common Rail, the output still there. To determine the parameters in TAVDA just attach a voltmeter to the red wire of high pressure sensor, turn ignition on and rotate the engine with the starter.At the time of turning the key to position "II" with the red wire must be removed voltage from 0.00 to 0.07 volts, when the starter this figure should be above 0.5 volts, which indicates the presence of pressures greater than 250 ATM. It is so much required for a successful motor start.
7
If the readings exceed 4.5 volts, which is equal to the pressure in TAVDA 1450 ATM. and above, the ECU instructs the valve controller, and it resets the fuel in the return line.
