Fondant Cake You Could Make at Home

Some of you might need to monitor the pulse oxygen by some portable devices, so that you could know exactly how it goes wherever you go. For those of you, the cheap finger pulse oximeter would be a great option.

The fingertip pulse oximeter is used in measuring the carbonation rate and pulse oxygen pulse through the finger, and this portable one, OLED Spo2, is fit for family, hospital, oxygen bar, community healthcare, physical care in sports (it can be used before or after doing sports and it is not recommended to use the device during the process of having sport) and etc. Not recommended to be used for monitoring patients for a long time without any rest. Do not use the device in the environment MR/CT, in an exprosive atmosphere, or on infant or neonatal patient.

And of course, there are some cautions that you should better know, so that you could use the pulse oximeter for longer time. Not allowed high temperature or high pressure steam disinfection for the oximeter; and do not have the oximeter immerged in liquid. The operation of this device below the minimum amplitude of 0.4% modulation may cause inaccurate results. The device is designed to measure the percentage of arterial oxygen saturation of functional hemoglobin factors that may degrade the performance of the pulse oximeter or affect measurement accuracy include the following:

Do not apply the pulse oximiter pulse on the same arm as blood pressure cuff, arterial catheter or infusion line (IVs). Excessive light would also make a difference to the device, such as sunlight or direct home lighting. Moisture in the device would do harm to the device, so keep the device dry. Finger is outside recommended size range. Poor quality pulse and venous pulsation. Anemia or low hemoglobin concentrations might affect the accuracy. And surely, the artificial fingernails or fingernail polish will absolutely make a difference.
