Our approach to describing ventilator design has thus changed from a focus on individual components to a more generalized model of a ventilator as a “black box,” that is, a device for which we supply an input and expect a certain output and whose internal operations are largely unknowable, indeed, irrelevant, to most clinical operators. The green blocks in Figure 3 correspond to the “Inspiratory Flow Delivery System” in Figure 1. Ventilation Block. During expiration, the ventilator opens the “Expiration Valve” and closes the “Inspiration Valve”. This dynamic resistance partially occludes the path of the exhaled air so that the airway pressure remains at the desired level. But most of all a simple solution (although a good ventilator for anaesthesia for example) will not help Covid 19 patients, these individuals have complex changes to their respiratory mechanics which a non-complex machine can not match (in the days of simple ventilators in ICU, when the ventilator couldn’t cope the patient died), it is a testament to the medical engineers that produce these complex machines that have improved ICU outcomes. The example waveforms depicted in the above figure correspond to a relatively simple mode of operation where the ventilator operates independently from the patient’s respiratory reaction. 25 blocks per meter square.
