Nosebleeds are usually caused by an external force, such as a blow to the nose. And the climate is excessive: dryness (cracking the nasal membranes), sudden changes in air pressure, picking the nostrils with fingernails, or blowing the nose too violently, may also cause the nasal mucosa to be injured and bleed, and some ** nosebleeds will drip blood on the mouth, chin and clothes, which looks quite scary.

There are two types of nosebleeds: anterior and posterior. The posterior type mainly affects older people, especially those with high blood pressure.

In this type, blood flows from the back of the nose and down the back of the mouth and into the throat, regardless of the position the person is in. In severe cases, the direction of blood flow may be both anterior and posterior. This nosebleed requires hospital care.

The common nosebleed is anterior, which occurs from the front of the nose. When standing or sitting, blood comes out of one or both nostrils. When lying down, blood flow may go to the throat. This nosebleed can be scary, but it's not serious.

Whether it's due to dry weather, high blood pressure or hardening of the arteries***, or nosebleeds caused by accidentally breaking the nasal passages, the tips below are helpful for all kinds of nosebleeds.

Blow out the blood clot.

Before stopping the bleeding, try to blow out the blood clot. Because the blood clot that is blocked in the blood vessel prevents the blood vessel from closing. There are elastic fibers in the blood vessels, and when you remove the blood clot, these elastic fibers have a way to contract, so that the bleeding opening closes.

Sometimes, blowing your nose and pinching your nose a little with your hand will stop the bleeding.

Stuff gauze or damp cotton.

Stuff a small piece of sterilized wet gauze in each nostril, and you can also use Neo-synephrine decongestant or Afrin nasal spray to wet the cotton to cool the nostrils and help stop bleeding. But there are also experts who prefer to wet the cotton with white vinegar. The acetic acid in the vinegar burns slightly.

But decongestants only provide a temporary stop to the bleeding, and if you abuse them, they can damage your nasal membranes.

After pinching Yuezi After blowing the nosebleed (to remove blood clots) and stuffing cotton, pinch the nostrils together with your thumb and forefinger and continue to press for 5-7 minutes. If the bleeding does not stop, repeat the cotton stuffing and nose pinching, still pressing for 5-7 minutes. This should have a hemostatic effect.

Sit up straight If you lie down or tilt your head, it will allow blood to flow down your throat. You can sit in a chair and lean forward (don't put your head back).

Use cold compresses Cold can cause blood vessels to constrict and decrease.

Bacterial necrosis of the pith, the lower part of the stem is diseased, and the surface of the diseased part produces brown to black-brown lesions at the initial stage, which gradually expands upward, and the pith becomes black-brown when the diseased stem is dissected.

The original Jianfan plan produced a total of 1.44 million hailstones.

The first workshop originally planned to produce x thousands, (108-x) x = 20%, and obtained x = 900,000, and because the first workshop was originally planned to account for 5 8, the disadvantages were so.

90 divided by 5 8 = 1.44 million. Hope it helps.

This is an elementary school question!! For the first question, divide 1000000 by 1000! It is equal to one thousand, and one thousand times 10 centimeters is equal to ten thousand centimeters! 10,000 centimeters divided by 100 equals 100 meters!

(1) 1000000 divided by 1000 = 1000 1000x10 = 10000 10000 divided by 100 = 100 meters.

2) 10000-400=9600 9600 divided by 150=64.
