Minister inaugurates distribution of pulse oximeters All teachers should work as front-line warriors in the battle against COVID-19, Minister for General Education V. Sivankutty has said He was speaking after inaugurating here on Friday the State-level distribution of pulse oximeters purchased by the Kerala School Teachers’ Association (KSTA) through a pulse oximeter challenge. The Minister praised the social responsibility displayed by the KSTA during the pandemic. The pulse oximeter challenge was launched to address the shortage of pulse oximeters in the second wave of COVID-19 transmission in the State. Exceeds target Though the KSTA had targeted to hand over pulse oximeters to the tune of ₹1 crore in the first phase, the response had been so positive that it exceeded the target, a KSTA office-bearer said.
