Generation 2 Fingertip Pulse Oximeter with Lanyard

I'm not an expert... but this works a lot better than I expected. The real-time graph of blood flow is a surprisingly useful feature, both for making sure it's attached correctly and for generally seeing what's going on. If I manually measure pulse at my neck, it exactly matches what the display shows me onscreen at my fingertip, with only like a tenth of a second of delay. It's not particularly convenient to use while exercising, but it's also not particularly difficult either... and it works way better than the wristwatch-style heart monitor I tried before I got this. Haven't yet checked the oxygen readings against what the meter at my doctor's office says, but will do so at my next appointment. The pulse readings, however... are detailed, accurate, and quick. The main downsides I've noticed are that the graph mode can't be rotated, and it's difficult (but not impossible) to get a reading from toes.

As a thirty year Cardio Thoracic ICU nurse, I have a lot of experience with hospital grade pulse oximetry monitoring devices. With the crazy COVID cases in which the person has vague viral symptoms and is noted to have profound silent hypoxia, I decided to purchase a pulse ox for my family’s personal use. I found the device easy to use and very accurate when compared with hospital devices. It comes with a lanyard as well as padded case, and includes batteries. As others have mentioned, insert batteries carefully. They have two springs side by side which I think is confusing for insertion/placement . A special feature I really liked is the display of a pleth waveform on one of the views. This waveform helps visualize the intensity of each heartbeat. You can actually see how forcefully or weakly the heart contracts on each beat. This waveform also helps you to discern how accurate your readings are. If the waveform has a repetitive row of hills traveling across, then you are giving good info to the machine and the readings are more accurate. If the waveform is erratic and you have no sat reading or low sats then there may be too much interference from movements or not enough blood flow for device to work. Place device on thumb, index, or middle fingers that are not too cold and have person hold extremity very still while obtaining reading for more accurate results. I highly recommend this device for personal use for its ease of use, accuracy, value, and convenience.

Works accurately

I got this after being exposed to Covid to monitor oxygen levels. I chose this one because it also actually showed your heart rhythm under the oxygen and heart rate readings. It was very easy to install batteries and get my 1st reading. When I used it, it read pretty much what I typically read at the Dr's office. I was very pleased with how it worked and the bright, clear display. However, I gave it only 4 stars because it seems to have a hard time reading my husband's fingers. He has worked construction his whole life and has fairly large fingers. We could only get it to work on his pinky and even that took a while to get a good reading. It seems like a very good product if you don't have large or callused fingers.

easy to use and appears to be accurate.

Ordered this for my wife as I bought one earlier. It's an excellent product

Works as it should

I purchased this product so I could track my arrhythmias, pulse rate and oxygen content in my blood. I find it so easy to use (and that's important because I'm not particularly tech savvy). It offers several choices of how it shows the information . . .I haven't even read the instructions yet and I've been using it successfully for 2 days! It appears to be very sensitive to changes in pulse rate and reveals those changes. It also shows graphically when I am having arrhythmias. it also reveals when my heart beats are strong or weak . . .like when exercising they are more forceful than when resting . . .and I can graphically see the difference. I also enjoy the nice design and color combination, the information is easy to see daytime or night. It comes with a carrying case and lanyard and two AAA batteries. A great choice!!

Great machine, puts my mind at ease with kids croup and asthma. Easy to use. Quick, kids like it

This is an excellent product. It does what it is supposed to do. Highly recommended.

Very simple use and clear display. Easily worth every cent.

GREAT!!!!
