In medicine, mechanical ventilation is a method to mechanically assist or replace spontaneous breathing of a patient using a machine called a ventilator. Mechanical ventilation is often a life-saving intervention, but carries many potential complications including pneumothorax, airway injury, alveolar damage, and/or ventilator-associated pneumonia, thereby requiring that a respiratory care practitioner operate the ventilator.
The delivery of a “gold standard” of care in mechanical ventilation to a patient population relies on having a sufficient number of acute care ventilators on hand as well as a requisite number of respiratory care practitioners to properly operate them. Recognizing that in a severe pandemic like the 1918 Spanish Flu pandemic, or a mass casualty event, such as a major earthquake, hurricane, or terrorist incident, the very real possibility exists that patient loads generated by such events will initially exceed the number of stockpiled ventilators and/or the requisite number of respiratory care practitioners on hand to provide even a modified gold standard treatment to a large number of patients requiring mechanical ventilation. Even if a sufficient number of mechanical ventilators are stockpiled in a particular area, the large number of immediate casualties in such a catastrophic event could overwhelm the limited number of respiratory care practitioners available to provide the necessary expertise to operate all of the ventilators required to treat a large number of patients, especially those patients not being treated by emergency personnel or at a healthcare facility, such as a hospital. Accordingly, there is a need for a ventilation system that may be operated by a non-expert with no or little experience in the operation of a ventilator as well as a ventilator adapted for seamless adjustment of ventilator functions and parameters by a respiratory care practitioner. There is also a need for a ventilation system having various modes of operation that can be utilized to mechanically ventilate patients outside a hospital setting without an AC power source.
