Why Would A Pulse Oximeter Provide Just Me A Fake Reduced Reading Just A Few Of The Time?

[gillian59]

Nail polish wasn't utilised by me and my hands are comfy. The components appear to come when I am going gradually and exhausted. My oximeter is approximately 7 years old...have not used it in six years(it was my Father's). It always gave me good components, 6 years back. When I visited my GP's workplace, his device also created an(assumably false) lowered reading...a excellent reading following I lay for awhile. His oximeter was fairly old, as well. Following I visited my pulmonary doctor's office, her oximeter and mine both gave precisely the same great reading oneday, then your the following month, mine gave me a low reading whilst hers gave me a very good reading(was with them simultaneously to try to calm my be worried about the low components). My oximeter gives absolutely everyone wonderful components continuously. What may well it be about me that tosses these devices down?

A handful of factors come to mind. There are several things that can alter biox readings. You described your warm fingers and lack of fingernail polish, which can alter the readings, but there are numerous other issues that can trigger low or false readings. Poor circulation, level of activity prior to the reading, low blood pressure, poor sensor placement, patient movement, smoking, low hemoglobin level, thickness of skin, bone, and fingernails? just to name a few.   Are you sure that the low readings you are receiving are really false? If your readings are lower at house when you are tired, possibly your heart price and blood pressure are decrease at these instances. Also, it does take the biox at least 10 seconds or a lot more give an accurate reading so wait a bit until the numbers quit jumping around to read your level.   A handful of issues come to thoughts that may result in a distinction in the two readings completed simultaneously in your physicians workplace. Bright lights can interfere with readings. They compete with the sensor light and can lead to larger readings. Was your medical doctors probe in brighter light than yours? Also, have you cleaned your probe lately? You don?t mention what kind you use? I assume it?s a finger probe. You may possibly want to clean yours with some alcohol. Skin oils, dirt, blood etc. can lead to an inaccurate reading.  I just cleaned a actually dirty a single this morning and it created a huge difference.   You described that in in your GP?s workplace, the reading began low and right after you sat for awhile it got larger. Have been you brief of breath at the time? Maybe after you sat and rested for awhile, slowed your breathing down, and took deeper breaths, your biox level improved.   Be careful not to check your oxygen saturation as well significantly. That can be like a dieter standing on the scale 20 times a day. You can drive yourself crazy with worry and that isn?t good for you. You may just want to verify it a specific occasions of the day, like when you initial wake up, following strenuous activity, and also if you are getting difficulty breathing.

I've worked with pulse oximeters in the past. I've never known them to give false readings.   You reading should be in the 90% range. Some people who have breathing problems have their readings fall while they are sleeping because they don't get enough air.   There are a few of things you can do: 1. Wipe the finger clip clean. It works with light so a dirty clip may affect the reading. 2. You can use another person as a sanity check. Check another persons reading and make sure theirs is consistent. When you think your is not reading right check theirs. 3. It is unlikely but something may have happened to the electronics. You can always contact the company who made it and ask them if they can check it?   I'm wondering, Why do you have a pulse oximeter anyway? Do you have a known health problem? That may be your problem.

as a respiratory therapist,based on the scenario. i'd venture to guess your sensor is too old and the physicians is over-used and needs more frequent replacing. not knowing which brand you have,it could also be the unit needs calibrating.  also the "false low" is it oxygen saturation only ? does the heart rate corolate with your pulse ?

There are many things that can alter biox readings. You mentioned your warm fingers and lack of fingernail polish, which can alter the readings, but there are many other things that can cause low or false readings. Poor circulation, level of activity prior to the reading, low blood pressure, poor sensor placement, patient movement, smoking, low hemoglobin level, thickness of skin, bone, and fingernails? just to name a few.   Are you sure that the low readings you are getting are truly false? If your readings are lower at home when you are tired, perhaps your heart rate and blood pressure are lower at these times. Also, it does take the biox at least 10 seconds or more give an accurate reading so wait a bit until the numbers stop jumping around to read your level.   A few things come to mind that might cause a difference in the 2 readings done simultaneously in your doctors office. Bright lights can interfere with readings. They compete with the sensor light and can lead to higher readings. Was your doctors probe in brighter light than yours?

Were you short of breath at the time? Maybe after you sat and rested for awhile, slowed your breathing down, and took deeper breaths, your biox level increased.   Be careful not to check your oxygen saturation too much. That can be like a dieter standing on the scale 20 times a day. You can drive yourself crazy with worry and that isn?t good for you. You might just want to check it a certain times of the day, like when you first wake up, after strenuous activity, and also if you are having difficulty breathing.

replace the oximeter finger sensor as a respiratory therapist,based on the scenario. i'd venture to guess your sensor is too old and the physicians is over-used and needs more frequent replacing. not knowing which brand you have,it could also be the unit needs calibrating.  also the "false low" is it oxygen saturation only ? does the heart rate corolate with your pulse ?
