The Tokyo Metropolitan Government will use three indicators to consider requesting the issuance of a state of emergency when a certain number is reached.
Either the bed usage rate for critically ill patients, which was calculated based on the new criteria based on the characteristics of the Omicron strain, or the percentage of inpatients who require oxygen administration, is either 30% to 40%, and is new. This is the case when the 7-day average number of positives reaches 24,000.
Of these, the bed usage rate for critically ill patients, which was calculated based on a new standard based on the characteristics of the Omicron strain, was 34.9% on the 20th, a decrease of 0.2 points from the 19th.
The target severely ill patients are those who are using the conventional standard ventilator or ECMO = artificial cardiopulmonary device, as well as those who are undergoing "high flow therapy" that administers a large amount of high-concentration oxygen. It also includes patients who are likely to need these treatments and are in the ICU.
In addition, the percentage of inpatients requiring oxygen administration was 18.9% on the 18th, but there was no announcement on the 20th.
According to the capital, the next announcement is scheduled for the 21st.
The 7-day average number of new positives was 14,8004.9 on the 20th, a decrease of 19.8 from the 19th.
