    The index focuses less on how likely a disease will spread worldwide – that is, become a pandemic – and more upon how severe the epidemic actually is. [8] The main criterion used to measure pandemic severity will be case-fatality rate (CFR), the percentage of deaths out of the total reported cases of the disease. [ 3 ]

    en.wikipedia.org/wiki/Integrated_Pulmonary_Index

    Integrated pulmonary index (IPI) is a patient pulmonary index which uses information from capnography and pulse oximetry to provide a single value that describes the patient's respiratory status. IPI is used by clinicians to quickly assess the patient's respiratory status to determine the need for additional clinical assessment or intervention.
