pulse oximeter production affected by lack of mainboard and chips 
in last one week, our production of pulse oximeter has been affected obviously by the lack of mainboard and chips, at same time, market request of pulse oximeter from India keeps increasing.
May.01-05 is public Labor day holiday here in China, all these are causing the current market pulse oximeter price high.
same pulse oximeter costing around usd3 now price rises to almost usd6 today,  it's already doubled.

per dicussion with our board mills, this situaion may be improved around mid of May.
