Well, while the Metene Pulse Oximeter from Fingertip cannot be used overnight, its accuracy and reading speed will make it easy for you to check your pulse rate when you wake up in the middle of the night. A soft LED light is also included to match the all-white color scheme, which makes it suitable for nighttime use and prevents you from becoming blinded by the light. In addition, the price is really affordable as well.

Some people avoid using the fingertip oximeter for fear of it falling or being uncomfortable while sleeping. That’s why Garmin presents the Vivosmart 4, which continuously monitors your blood oxygen saturation, heart rate, and sleep as well as your energy and stress levels. Because it is worn on your wrist, you can sleep in various positions without worrying about it falling, or having your fingers hurt from being clipped.

"I LOVE this watch. I love how it stays charged for a week and that’s the only time I have to take it off. I love how it syncs with my iPhone but is small and pretty on my wrist. I love how accurately it tracks my movement and workouts and sleep, and syncs instantly the data to my phone! Even my pulse ox! And it is an incredible price for all that it does."

This one isn’t designed for medical use but it can give you the function you’re looking for. The Apple Watch Series 6 is equipped with motion sensors to measure how you sleep. Recently, Apple adds a pulse oximeter that uses a cluster of four IR LEDs that take a SpO2 measurement in just 15 seconds, and that can monitor the values 24/7. Of course, this smartwatch has many other features that will benefit you a lot if you have no problem with your budget.
