An Oxygen Concentrator is a type of medical device used for delivering
oxygen to individuals with breathing-related disorders. Individuals
whose oxygen concentration in their blood is lower than normal often
require an oxygen concentrator to replace that oxygen.
It`s
also equipped with special filters and sieve beds which help remove
Nitrogen from the air to ensure delivery of completely purified oxygen
to the patient. These devices also come with an electronic user
interface so you can adjust the levels of oxygen concentration and
delivery settings. You then inhale the oxygen through the nasal cannula
or special mask.

1. Early: To invest in concentrate feed. Because the wintering and transportation of the fish species makes them weak, they must choose high-quality feed, such as fresh green and yellow sturgeon, in order to make the fish return to constitution as soon as possible. In the early stage, due to water temperature below 28°C, it is more suitable for the growth of large yellow croaker. It is necessary to feed enough feed to make it grow rapidly. This will lay the foundation for the large yellow croaker to reach the commodity specifications in the year.
2. Mid-term: Control the amount of feeding. Because mid-breeding coincides with the high temperature period from July 10 to August 31. Although the fish are looking for food, if the fish eats too much, they can easily cause diseases such as enteritis and excessive feeding will cause pond water quality. deterioration.
3. Late: Put enough feed. The quality of the feed in the later period can be appropriately reduced, and some fresh fish can be thrown. Due to the large number of fish in the pond after September, and all of them entering the peak of growth and foraging, they competed with the large yellow croaker. If the fodder concentrates, it will increase the breeding cost. If the amount of bait is insufficient, it will affect the growth of large yellow croaker.
4. Types of Feed The feeds for large yellow croaker are generally capable of three types of feed. Biological feed, fresh feed and artificial feed. However, in adult fish farming in ponds, it is difficult to meet the growth requirements of large yellow croaker. Fresh feed is currently dominated by blue and yellow snapper. However, large yellow croaker uses a single green and yellow snapper to make the quality of large yellow croaker landing. It is manifested in large fish belly, pale color, high fat content, poor taste, etc., and because The use of large quantities of green and yellow squid will cause the prices of green and yellow squid to rise significantly, raising the cost of breeding and lowering the benefits. Due to the long history of artificial ration feeds for large yellow croaker breeding, the nutrient requirements for the fish have not yet been fully understood, and companies are not yet able to produce full-scale mixed feed for large yellow croakers. According to our practical experiment, the total growth of large yellow croaker is obviously lower than that of fresh feed. At the same time, the prices of high-protein, high-nutritive compound feeds produced by various companies are too high, making it difficult for farmers to receive them. In order to deal with these problems, we used the method of dry-fresh mix of feed in the cultivation, and disposed of the above problems better. After adopting the method of fresh and dry feed, the fresh feeds used do not necessarily need to be green and yellow catfish, and ordinary fresh fish can be used, which is beneficial to the cost of landing. After using the dry-fresh mix method for feed, it can use the dry feed to add sugar, plant protein, inorganic salt, minerals, vitamins, trace elements, nutrients, etc. necessary for the growth of large yellow croaker, which will help balance the nutrition structure of the feed. Strengthen the fish's physique and improve resistance to disease. The results we have used show that the use of fresh and dried fodder not only reduces the cost, but also significantly improves the fish's body shape, body color, taste, etc., even when it is used in cage culture. The survival rate of aquaculture has obviously improved.
5. Feeding times and time: Daily feeding is generally twice. Separation is given before and after sunrise and before and after sunset. It is best to choose the feeding point near the drain gate in order to discharge the sewage.
6. Feeding amount: According to the different stages of the growth of large yellow croaker, the theoretical feeding amount is 10% in the previous period, 8% in the middle period, and 5% in the later period. However, when we actually use it, we feed the bait based on the previous period and control the medium term feeding. Feeding guidelines, separation by 10%, 6%, 7% feeding. The amount of bait also needs to be adjusted according to the innovation of the climate, especially in the later period when the cold air or the northwest wind is less than 5th level, it will be less or not bait.
7. If fish breeding is to be carried out, first consider the small larvae of large yellow croaker and need feeds with higher nutritional value, and use the feed of self-made grain size of 0 to 2 mm of black seedlings to feed them, supplemented by labor at night. Illumination utilizes the phototaxis characteristics of food organisms to guide biofeeds for the consumption of large yellow croakers. As with adult fish farming, feeding should be controlled in the medium term and bait should be added later.
8. Feeding observation: Pond culture of large yellow croaker is not easy to see when feeding time, when feeding, large yellow croaker will appear in a fixed location, so take advantage of this opportunity to carefully observe the large yellow croaker: 1) Observe the size and growth status of the fish; (2) Observe the movement status of the fish with or without diseased seedlings; (3) Observe the amount of the miscellaneous fish, etc. According to the observation results, the variety, structure, and feeding amount of the feed should be timely adjusted to prevent and treat the possible diseases.
(II) Water quality Controlling ponds Culture of large yellow croakers can cause large changes in water quality. In high temperature periods, the ponds may experience “red tides†in some areas. Therefore, the conditional pond should insist on changing the water every day, and the high temperature period can be considered twice a day. Change the water during the high temperature period as much as possible between 6 pm to 10 am the next day. Changing the water on the one hand can drop the water temperature, on the other hand, it can improve dissolved oxygen. Every 15 days, the water is poured with calcined water to improve the water quality and sediment quality.
(3) The patrol pond insists on daily morning, evening and evening patrols, especially when the water temperature is high and the tide is difficult to change. Special attention should be paid to the work of patrolling the pond at night and in the early morning.
(4) The natural enemies of fish breeding against the enemy are the most damaged in the middle and late breeding period of large yellow croakers. Therefore, birds must be deported to access the ponds. However, large-scale methods such as firecrackers cannot be used. This will make the big yellow croaker jump startled and not conducive to its growth.
Generally,
you can`t buy an oxygen concentrator over the counter. A doctor must
prescribe it after they`ve completed a thorough medical evaluation. The
doctors will also typically show the patients how to effectively use
these concentrators while traveling and in their home.
Oxygen
concentrators filter surrounding air, compressing it to the required
density and then delivering purified medical grade oxygen into a
pulse-dose delivery system or continuous stream system to the patient.

(I) Feeding management Feeding and feeding is an important part of aquaculture management. The variety, quality, amount of feed, number of feedings, and feeding time all affect the life and growth of large yellow croaker. According to our years of breeding experience, the pond culture of large yellow croaker should be done first and then thick, specifically:
