In order to provide the best possible medical care to patients suffering from Covid-19, hospitals around the world are upgrading. They are procuring additional ventilators and increasing the number of beds in intensive care units. Before the Corona crisis, there were about 22,000 intensive care beds with ventilator capability in Germany nationwide. By December 2020, the number could be increased to over 28,000, the German Hospital Association reported. In addition, there is a reserve of up to 12,000 more beds that can be put into operation if needed. Operating the lung machines, however, is not so easy: for ventilators to work, the air temperature must be measured and constantly monitored. The oxygen-enriched breathing gas must be close to the patient's body temperature and be able to be adjusted if it is too humid or too dry.
An even greater challenge is vaccine procurement. Finally produced and licensed, it is now important that the vaccine reaches doctors and vaccination centers safely. The cold chain must be maintained at all costs - and at extreme temperatures. The vaccine from Moderna, for example, has to be transported at minus 20 degrees, while the vaccine from Biontech and Pfizer even needs sub-zero temperatures of around minus 70 degrees in order to be effective.
