  1. Respiratory machine is very important for COVID-19 patients   In the treatment of COVID-19 patients, the medical respiratory equipment  is a crucial step. Whether it is severe or mild COVID-19, the respiratory machine will be used to prevent them from having breathing difficulties.   We can learn from the news that the number of COVID-19 diagnosed every day in the world is on the rise, and the number of confirmed COVID-19 worldwide has exceeded 30 million, among which the number of existing COVID-19 patients in the United States, India, Brazil and other countries has exceeded a million.   2. The COVID-19 affects the price of the respiratory machine   Every patient with COVID-19 should be matched with a respiratory machine , but because the respiratory machine is now in short supply of medical equipment. There is simply no way to meet the standard of one respiratory machine per person, and even patients with severe pneumonia may not have a respiratory machine in some places.   The

  With the development of medicine and the continuous updating of medical equipment, more and more clinical treatment items and operations that are beneficial to patients have emerged. This requires us to continuously learn and enrich ourselves. In recent years, HFNC machine has been widely used in the intensive care unit, and what follows is the issue whether our usage is reasonable, and the evaluation of the effect after use.   Is the HFNC machine really used correctly? The following is the relevant knowledge of HFNC machine  sorted out   1. The air-oxygen mixing part of the HFNC machine's gas   Its function is to mix air and oxygen in front of the turbine according to a preset oxygen concentration. There are two methods for oxygen concentration control. One is to control the oxygen concentration by adjusting the oxygen flow through a buoy-type oxygen flow meter. This method cannot preset the oxygen concentration, and can only generate actual FiO2 by adjusting the oxygen flow; th

  Nowadays, due to the gradual improvement of the level of social and economic development, relatively, medical technology also has a certain development trend in order to solve various difficulties in medicine, treat various diseases with high difficulty coefficients, and many new treatments. The methods have been scientifically researched and applied to the clinical medicine profession. HFNC machine is one of them. The following content is a practical introduction of the characteristics of HFNC machine.   Ⅰ. The HFNC machine can heat up, humidify and feed oxygen with a high total flow rate   The HFNC machine can administer CO2 with a higher concentration of heating and humidification through the nasal cannula. The total air flow can reach 60L/min, because the total air flow can be set to exceed the total respiratory peak flow level of most patients with inspiratory decline, thereby ensuring the stability of the oxygen concentration.   The warming and humidifying effect of HFNC machin

  Ⅰ. What diseases is HFNC machine suitable for?   1. It can be applied to acute hypoxic respiratory failure type I respiratory failure;   2. Patients with respiratory failure without tracheal intubation;   3. Before and after tracheal intubation or tracheotomy and extubation;   4. Painless bronchoscopy auxiliary treatment ( HFNC machine  is used in painless fiber bronchoscopy, which makes anesthesia effect good, greatly improves patient's comfort, and provides the operator with a good working condition);   5. Patients after surgery;   6. Patients with cardiac insufficiency after cardiac surgery, etc.   Ⅱ. What are the advantages of HFNC machine?   1. HFNC machine can reduce respiratory dead space, improve alveolar ventilation, generate a certain positive airway pressure, reduce respiratory work, and effectively improve oxygenation;   2. Improve upper airway resistance and respiratory function;   3. High-flow heating, humidification and oxygen supply, good humidification improves t

  In 2014, the HFNC machine began to be used in China, and it has been rapidly popularized in clinical practice within a few years, and its clinical efficacy has been widely recognized by doctors in the top three hospitals. It also played an important role in COVID-19. However, the general public does not know much about the HFNC machine, so it has not been widely popularized in secondary hospitals, community hospitals, rehabilitation hospitals and nursing homes.   Ⅰ. What is HFNC machine? The  HFNC machine  refers to a high-flow nasal congestion that continuously provides patients with a treatment equipment with relatively constant and controlled oxygen concentration (21%-100%), temperature (31-37 ℃) and high humidity (8 -80 L/min). The equipment mainly includes an air-oxygen mixing device, a humidification treatment instrument, a high-flow nasal obstruction and connecting breathing tubes.   Ⅱ. Who is suitable to use the HFNC machine? The High Flow Nasal Cannula  machine can be used f

  Adults often have complications such as hypoxemia, pulmonary infection, and atelectasis after cardiac surgery. Oxygen therapy is often required after tracheal intubation is removed to maintain adequate alveolar ventilation and oxygenation.   1. Case of using HFNC  machine A 64-year-old bypass patient in the Department of Cardiac Surgery was immediately transferred to the ICU for treatment because he did not dare to cough, had thick sputum, and hypoxemia caused by respiratory distress. According to the previous routine, after sucking the sputum, the patient needs to be given non-invasive ventilator assisted ventilation to improve hypoxemia, but this time the ICU used a very effective  HFNC machine . After the patient inhaled high-flow oxygen through the nose for half an hour, The breathing is stable, the symptoms of hypoxia have been significantly improved, and the comfort level has also been greatly improved.   This starts from its source: common oxygen therapy equipment such as ordi
