How to use max30102 with other sensors?and calculate spo2?

[UfkuAcik]

Hello; I am planning to use this library with bme280 sensor,which has some delay functions in superloop.

But as I can see; This library needs to check max30102 interrupt flag continually inside superloop.

How can I use both sensors together?(Without RTOS preferably) //////////////////////////////////////////////////////////////////////////////////////// Also how can I calculate spo2 using this library?

Is just using someting like below is ok?

Or usage of an algorithm is needed,like below:
