How can we measure accurate and stable SpO2 with less stress to patient?

Even though CO2 is important and recommended by ASA/APSM Guidelines, we have a lot of difficulties as below;

1. No portable CO2 monitor
2. Delicate and easy to break, and short lifetime
3. Long CO2 calibration and long warm-up
4. Condensation or water trapped in sampling line
5. Slow response, or long time to get results
6. Difficult calibration 
7. Not available for child because of bulky size, dead space
