New Coronavirus Pneumonia (Name as COVID-19)
Its main pathogenesis is that inflammatory secretions or exudates are abundantly filled within the lung interstitium and alveoli, thus it blocks fresh air from entering the alveoli and exchanging CO2 within the body, leading to the body's hypoxia and even multiple organ failure to death. at the present, there are not any special drugs against the new coronavirus. More symptomatic supportive therapy is employed, Oxygen inhalation may be a vital symptomatic treatment measure throughout the treatment of latest coronary pneumonia.
The firstly, why wouldn't it be hypoxic?
The main function of the lung: complete the gas exchange of oxygen and CO2.
The lungs are the primary gateway for fresh oxygen from the surface to enter the body. Oxygen enters the lungs with breathing, and exchanges with CO2 through the capillary network of the alveolar wall, this exchange may be a physical diffusion process under the effect of oxygen or CO2 partial pressure difference, from the vena pulmonalis (pulmonary circulation) into the guts then from the aorta (systemic circulation) transport oxygen-rich blood to varied organs and tissues of the body. A healthy adult's breathing capacity is 450-500ml at a time, about 9 liters of air per minute, about 12960 liters of air per day, like 16.8 kg, the aim of inhaling such a lot air is to ingest about 3.5 kg of oxygen. the standard of lung function directly determines the quantity of gas exchange. The greater the capacity, the more oxygen is inhaled, the stronger the alveolar diffusion function, and therefore the healthier the person.
The secondly, Hypoxia monitoring
1. Oxyhemoglobin saturation（SaO2）
Refers to the proportion of oxygen and hemoglobin, it's the foremost widely used and most easily obtained data, it reflects the combined amount of oxygen, the advantage is that it are often continuously monitored, but it's easily interfered by external factors, in theory, it can never reach 100% saturation. Normal people are generally 95%-100%, but 94% are often considered hypoxia, SaO2<80%, can basically be diagnosed as hypoxemia, SaO2: 60%-80%, suggesting obvious hypoxemia, SaO2<60%, suggesting severe hypoxemia. The finger oximeter most commonly used in general medical clinic, it has the characteristics of easy operation, non-invasiveness, precision and portability.
2. Blood gas analysis
Arterial oxygen partial pressure (PaO2) refers to the quantity of physically dissolved oxygen within the blood, after combining oxygen into the body, it must first dissociate into dissolved oxygen before it is often employed by tissue cells, it can objectively reflect the body's hypoxic state at the time, but it can't be continuously and dynamically observed and wish to draw blood to finish. the traditional value is 80-100mmHg, usually PaO2 < 60mmHg are often diagnosed as hypoxemia, PaO2< 50mmHg indicates the presence of respiratory failure, PaO2< 40mmHg indicates severe hypoxia, PaO2< 30mmHg indicates life-threatening. PaO2 will decrease with age, and it are often considered as hypoxemia when it's below the lower limit of an equivalent age.
The last, Advice for inhaling oxygen
1.The purpose of inhaling oxygen
It includes five aspects:
1) Maintain normal physiological indexes of blood oxygen saturation
2) Protect organ function
3) Repair organ damage thanks to hypoxia
4) Reduce inflammatory exudation
5) Enhance human immunity
2. The way to inhale oxygen
Inhaling oxygen by nebulizer：Germany reported that the nebulization method was wont to cure 4 patients with new coronary pneumonia during a short time, if nebulized oxygen therapy is employed, it's going to bring more benefits to the patients. Drugs are often delivered on to the tract and alveoli by nebulization. JoRadiant oxygen generator is provided with nebulizer function, supplying oxygen+nebulizer, One machine for 2 purposes
Inhaling oxygen by high flow：It is suitable for severely ill patients with weak breathing, and has achieved ideal leads to the treatment of latest coronary pneumonia. it's better to rest for five minutes after inhaling oxygen every 1 to 2 hours. the ten-lift flow medical oxygen generator developed by JoRadiant company is widely utilized in high-flow oxygen therapy.
3. Patients that infect coronavirus must still enforce oxygen therapy after recovery
Most patients think that everything is going to be fine after rehabilitation, in fact, the patients have already suffered damage to their body organs during treatment, especially after lung injury, which can indirectly affect the shortage of oxygen in other organs, if oxygen isn't supplied in time, it'll cause reduced organ function, and even worse, there'll be inflammation or failure. Therefore, after discharge from the hospital, we should always enforce the recovery of oxygen therapy, the house oxygen generator has become an important medical device for family health.
