1, the market some intelligent oximeter built-in correction function, with its finger blood can be measured with biochemistry measuring venous blood similar results. Some manufacturers of products with quality control fluid, test card, specifically to test the accuracy of oximetry as well as testing oximetry is working properly, in the purchase of attention to ask.
2, the size and clarity of the display, the battery replacement is convenient or not, whether the appearance is beautiful, how the size of the accuracy of the first should be clear that the accuracy of the current home oximeter is not up to the diagnostic standards. But its measured blood oxygen content value, should be similar to the biochemistry instrument to measure the test value of venous blood, can not be too different.
3, look at the warranty program and other after-sales service, service should understand the warranty period of oximeter.
4, look at the brand and price. When selecting an oximeter, not only should look at the price of the instrument, but also consider the overhead of consumables. In addition, choose the brand oximeter product quality is guaranteed, the measurement results are more accurate. Which brand of oximeter is good? I recommend the top ten brands of oximeter.

The following small introduction for you on the market has been the advantages and disadvantages of portable oximeter (product form including: nail oximeter, palm oximeter, wrist oximeter, health watch type oximeter), to help you pick.
One, fingernail oximeter
Advantages:
1, the product is small, no cable, easy to carry.
2, easy to operate: just one step - finger inserted into the machine, intelligent automatic power-on monitoring, finger out of the machine, automatic power-off power saving.
3, a wealth of monitoring functions: oxygen saturation, pulse rate, perfusion index (reflecting the measurement site of blood perfusion, the greater the pulsating blood flow, the more pulsatile component, the greater the PI value, the greater the accuracy of the measurement of oxygen saturation).
4, Bluetooth data transmission: through Bluetooth transmission, to realize the synchronous display and mass storage of data on the cell phone.
5, Shade design: Shade design, effectively shield the interference of ambient light on the measurement.
6, energy saving and environmental protection: with power management function, 8 seconds no signal automatic shutdown, and battery power management.
7, medical grade products, with medical device registration certificate.
Disadvantages:
1, non-rechargeable: using two 7 dry batteries, two dry batteries can be measured continuously for about 30 hours.
2, easy to fall off: oximeter plus two No. 7 batteries clamped on the finger, the weight is relatively large, the finger to withstand the force, sleep monitoring is easy to fall off.
3, comfort is not high: a long time to wear, clip clip on the finger, it hurts, comfort is not high.
Second, palm oximeter
Advantages:
1, medical-grade products, with medical device registration certificate.
2, can monitor parameters: oxygen saturation, pulse rate, perfusion index.
Disadvantages:
1, the cable is too long, not convenient to carry, non-wearable device.
2, not rechargeable: dry battery is used.
Three, wrist oximeter
Advantages:
1, compact design, the host is worn on the patient's wrist, the oxygen probe is worn on the fingers, the fingers bear the strength of the small, high comfort.
2, low power consumption, with rechargeable 3.7V lithium battery, can be recharged and used.
3, small size, light weight, easy to carry.
4, the product will automatically shut down when no signal is generated.
5, Sleep monitoring system, data can be displayed on PC or cell phone via Bluetooth.
6, Medical grade product with medical device registration certificate.
Disadvantages: external blood oxygen probe, if you need to choose the right blood oxygen probe.
Four, health watch type oximeter
Pros:
1, a set of blood oxygen, pulse rate, ECG, pedometer in one health watch, easy to carry.
2, display parameters: blood oxygen saturation value display, pulse rate value display, heart rate value and ECG waveform display, pedometer steps, calories display.
3, data storage function, stored data can be wirelessly uploaded to the mobile terminal.
4, with clock function.
5, rechargeable function.
6, the side to provide reflective blood oxygen, also provides sleep monitoring blood oxygen level probe. Easy to measure.
Disadvantages: health-grade products, no medical device registration certificate.
In short, the use of intelligent oximeters has brought great convenience to middle-aged and elderly patients, but of course, patients must regularly go to the hospital for review, combined with medical equipment and home oximeter measurements, and listen to the doctor's guidance for the most reasonable and effective treatment of the condition.
