CATDOLL : CATDOLL: How many types of fish suffer from hypoxia? What are the symptoms of hypoxia in the blood?

1. How many types of oxygen-deficient fish are there?

There are many fish that are not afraid of lack of oxygen, such as guppies, mollies, moonfish, goldfish, and bettas. Most of these fish can live in an environment with low dissolved oxygen due to their small size, and some have special auxiliary respiratory organs, so they can breathe on the water surface, and low dissolved oxygen will not affect their lives. However, in order to make the fish grow better, it is best to use an oxygen pump to oxygenate it.

2. What are the symptoms of hypoxia?

After blood hypoxia occurs, the patient may experience symptoms of central nervous system hypoxia such as dizziness, headache, tinnitus, blurred vision, insomnia, forgetfulness, etc. He may also experience shortness of breath, chest tightness, palpitations, which can easily induce angina pectoris and chest pain. It may also reduce the oxygen supply to the muscles of the limbs, causing soreness and weakness in the limbs, difficulty walking, and even hemiplegia.

3. What are the symptoms of brain hypoxia?

After brain hypoxia, patients will experience headache, dizziness, confusion, nausea, vomiting and other symptoms, and the severity varies depending on the duration of hypoxia. The brain has the most complex structure and the most important function. 20% of the human blood is supplied to the brain, so the brain is very intolerant of hypoxia. Usually, obvious brain edema will appear after 4 to 5 minutes of hypoxia.

4. What are the symptoms of hypoxia in the fish tank?

If the fish tank is lacking in oxygen, the fish will frequently surface and swim slowly. If the lack of oxygen is severe, they may even turn belly up.

5. What are the symptoms of hypoxia during mid-pregnancy?

If a pregnant woman suffers from hypoxia during pregnancy, she may experience chest tightness, shortness of breath, or abnormal increase or decrease in fetal movement, abnormal fetal heart rate, etc. Once symptoms of hypoxia appear, she should go to the hospital in time to check the cause and treat the symptoms. At the same time, she can use appropriate oxygen under the guidance of a doctor to relieve the symptoms and avoid excessive fatigue.

6. What are the symptoms of severe brain hypoxia?

Symptoms of severe brain hypoxia include dizziness, headache, tinnitus, blurred vision, and sometimes nausea and vomiting. There may also be slow thinking, slow reactions, drowsiness, feeling tired without much physical exertion, mood swings, and changes in temperament. As the degree of hypoxia increases, the symptoms will gradually worsen, such as rapid pulse, headache, nausea, general weakness, pale complexion, vomiting, blue skin, and in the most severe cases, even drowsiness and even respiratory arrest.

7. What are the symptoms of fetal hypoxia during pregnancy?

Fetal hypoxia during pregnancy is divided into acute hypoxia and chronic hypoxia. Acute hypoxia often occurs during delivery, and is mostly caused by factors such as umbilical cord prolapse, placental abruption, and excessive uterine contractions. In the early stages of hypoxia, pregnant women often feel frequent fetal movements. As the hypoxia worsens, the fetal movements weaken or even disappear. Frequent fetal movements alone are not a manifestation of hypoxia. Chronic hypoxia is mostly caused by pregnant women with gestational hypertension, chronic nephritis, or gestational diabetes. Pregnant women often feel weakened or reduced fetal movements. In this case, they should go to the hospital for examination in time to avoid serious consequences.

8. What are the symptoms of intrauterine hypoxia in babies?

If the baby's fetal movement becomes noticeably faster, the fetal heart rate increases, or the opposite symptoms occur, it is very likely that the baby is suffering from intrauterine hypoxia. It is recommended that if there are any abnormalities, the fetal movement should be detected in time and the fetus' condition should be closely observed, because if the fetus suffers from hypoxia, it is very dangerous. At this time, it is best to go to the hospital for relevant treatment in time.

9. How to domesticate the oxygen-deficient Cooper fish?

1. For the convenience of feeding, it is necessary to choose the edge of the pond; 2. For the convenience of fish feeding, this point should be the relative midpoint of the pond; 3. There should be no weeds or trees nearby and it should be sunny, and 1 to 2 feeding tables should be set up near the feeding point. At the beginning, feed along the four sides of the pond, feed more at the feeding table and its vicinity, and then gradually narrow the feeding range every day and move towards the feeding table. Generally, after 5 to 7 days of domestication, the fish can be led to the feeding point to eat. At the same time, during the domestication period, before or during each feeding, use methods such as knocking objects or whistling to make specific sounds, so that the fish will have a conditioned reflex to the specific sounds. When the fish hear the specific sounds in the future, they will gather at the feeding point to eat.

10. What are the symptoms of cerebral ischemia and hypoxia?

Cerebral ischemia and hypoxia can cause dizziness, headache, tinnitus, blurred vision, limb weakness, nausea, vomiting, shallow breathing, and a rapid and weak heartbeat. Because oxygen can only flow after combining with hemoglobin in the blood, but hypoxia does not necessarily cause ischemia. Sometimes the blood flows normally and the hemoglobin content is also normal. Severe hypoxia can cause cessation of breathing and asphyxiation.
