An exaggerated reaction by our immune system is refered as Allergy. The reaction happens in response to bodily contact with certain foreign substances. These substances are usually seen by the body as harmless. However no response occurs in non- allergic people.
Asthma is refers as the swelling and narrowing of the airways in our body. In technical terms it is called a chronic inflammation of the bronchial tubes. This results in breathing problems.
An inflammation of the sinuses and nasal passages is refered as Sinus infection or sinusitis. The infection may causes a headache or pressure in the eyes, nose, cheek area, or on one side of the head. The sinus infection may also cause a cough, a fever, bad breath, and nasal congestion with thick nasal secretions.

Customer Reviews

Appears like a very good item5
This looks and feels exactly like what they use at the doctor's office. The display is very convenient and very clear. It is very easy to use. Put your finger in (after cleaning with an alcohol pad, otherwise results could be wrong) and press the button.

It shows the pulse and the oxygen simultaneously. If you make movements that should increase or decrease either oxygen or pulse, it reflects it in real time and seems to make sense.

The only problem is that once you start using it, unless you have other means to test your pulse and oxygen, you wont know if its accurate. I recommend you take it to the doctor and when they do the checkup compare this to what the nurse uses to make sure numbers are the same.
Disappointed.1
After reading the reviews, I believed that this was a good choice for home use. I was sorely disappointed. The oxygen saturation reading was 9-10 points lower than the one at the clinic...so we were never above 91, and the heart rate reading was all over the map. We thought perhaps we moved our finger, our finger was cold, the pulse oximeter was cold....every reason/excuse we could think of. After taking it to the clinic, we realized it was just totally inaccurate.
Generally pleased with Oximeter.4
I bought this device because I have bouts of atrial fibrillation (the heart beats fast, irregularly -- and inefficiently). In the past I have occasionally had a feeling of insufficient oxygen when sleeping above 8000 ft, and in flight in airplane cabins. Since I am aware that conscious monitoring on one's breathing can interfere with the automatic process, I wanted to be able to get a measurement to confirm or deny a physical cause for my distress.

I have not yet had a chance to take the device to altitude, but I have used it to monitor at sea level, both while experiencing regular heartbeat and atrial fibrillation (afib). It has performed well. In particular, the graphical display of the blood pulse is very useful in getting a decent reading in adverse conditions. When in afib or when hands are chilled, there is little blood circulation through the fingertips, and the graph helps in getting a good "signal". It also helps in assessing the reliability of the pulse reading -- some devices have major problems in deciding on a pulse rate for an irregular heartbeat. One can eyeball the number of blood flow peaks in the display and get a rough idea of what pulse rate should be showing.

My principal disappointment is that it cannot make measurements while moving about. This is not the fault of the device, but is just due to its inability to distinguish blood pulses due to heartbeat from blood pulses due to muscle motion. It can take 10-15 seconds after motion stops for the device to hone in on the underlying pulse signal.

Another nit-pick is that the graphical display is only right-side-up when the oximeter is on a finger of the right hand. There are other display modes that reorient the digital display to be viewed from any angle, but these modes show the signal as a pulsing ribbon, not a graph.
