To Whomsoever It May Concern We have tested the product O2 optimiser developed by QTrack health systems private limited and find it to reduce our oxygen consumption while maintaining the FIO2 and SPO2%. This will be useful in saving the oxygen for patients on mask and canula. We have also requested them to modify this product to suit HFNC machines.

TO WHOMSOEVER IT MAY CONCERN This is to certify that M/s. QTRACK health systems had come out with an device called Oxygen optimizer. I have used this along with D type cylinder and found it extremely useful. It is a device that reduces the supply of oxygen from the cylinder and doubles the O2 supply at the outlet and hence the patient gets double the supply of 02 that what we keep in the fore flow meter. This device will be helpful in saving the O2 to the hospital and hence it is very useful at this time of oxygen crisis
