Novel coronavirus pneumonia is known to be an acute respiratory infection. Currently, there is no drug or medical regimen for it in clinical practice and oxygen therapy plays an important role in the treatment of COVID-19. With the emergence of a third wave of Neoplastic pneumonia in Myanmar, the widespread procurement of oxygen machines (oxygen therapy) for the treatment of Neoplastic pneumonia is of great importance. Are you using the right oxygen machine? How much blood oxygen level do you need to use an oxygen machine, how much inhaled pure oxygen do you need, and how big an oxygen machine do you need for your home?

It’s no doube that the oxygen is a gas that is essential for the survival of all living things on earth.  Who needs oxygen? Normally, a person's blood oxygen saturation is usually above 95, below 94% indicates an inadequate supply of oxygen. Below 90% is hypoxaemia. Therefore, oxygen therapy is required when blood oxygen is below 94%, especially in patients with poor lung function, and long-term oxygen therapy is recommended, which is very important for the patient's prognosis.

Molecular sieve oxygen generator technology is recommended for home oxygen concentrator. As an average consumer often look at the criteria of flow size and oxygen concentration, as the compressor and molecular sieve are the core of oxygen flow and oxygen concentration. Molecular sieve oxygen generation is a purely physical method of separating oxygen from air by a process of pressurised adsorption, depressurisation and analysis cycles using room temperature air as the raw material and molecular sieves as the adsorbent. Oxygen is separated in this way that

The concentration reaches the national standard of 93% +- 3%. This oxygen generator uses the adsorption properties of molecular sieves to separate nitrogen and oxygen from the air through physical principles, powered by an oil-free compressor, to finally obtain a high concentration of oxygen.

Except to the treatment of Covid-19, home medical oxygen concentrator can be used for patients with cardiovascular disease, coronary heart disease, cerebral thrombosis, hypertension, pneumonia, bronchitis, asthma or pulmonary heart disease, where long-term oxygen intake will have a good therapeutic effect. Alternatively, greater than 5L is a treatment type. When people inhale 5 or 8L the oxygen generator produces a maximum oxygen concentration of up to 93% and an alveolar oxygen concentration of 33-41%. For the patient, being able to give enough oxygen improves the body's general immunity, cleanses the respiratory system and improves the function of internal organs.

A common symptom of Covid-19 patient  is 'decreased blood oxygen levels'. Oxygen saturation levels represent the health of the human body, reflecting the health of the respiratory and cardiovascular systems, and play an important role in the prevention and diagnosis of human disease. Oxygen saturation monitoring is therefore of great physiological importance.

At normal lever of 0, normal arterial oxygen saturation in humans is 95-100%, below 94% is considered abnormal, and if it is below 90%, the level is considered low and is called hypoxaemia. Below 80% may impair organ function (e.g. brain and heart) and should be treated immediately; below 75% may lead to coma and unconsciousness and persistent hypoxia may lead to respiratory or cardiac arrest and subsequent death.

People with severe or critical illnesses, such as significant chest tightness, wheezing or even dyspnoea. Due to the severe inflammatory reaction of the lung tissue, the ventilation and diffusion function of the lungs can be affected. In this case, the patient may suffer from varying degrees of hypoxaemia, or even respiratory failure. Such patients require high concentrations of oxygen and should be taken to hospital promptly, as recommended by their doctor either by nasal cannula, oxygen mask or, in some cases of severe respiratory failure, but also by ventilator-assisted breathing to improve the body's hypoxic state and maintain organ function. Therefore, oxygen is also a treatment option for patients with severe COVID-19.

For COVID-19 patients, oxygen flow and concentration should be adjusted according to the patient's condition and lung function, and protective measures should be taken to avoid cross-infection. For critically ill patients, medical advice should be strictly and, if necessary, tracheal intubation and mechanical ventilation should be used to adjust the oxygen concentration. Promptly disinfect oxygen after inhalation.
