Meet the iProven Oxi-27 Pulse Oximeter

Discover the iProven Oxi-27 Pulse Oximeter

We’re excited to introduce the iProven Oxi-27: a fingertip pulse oximeter designed to be simple to use, easy to read, and helpful for quick wellness spot checks at home or after activity.

Most basic oximeters show oxygen saturation and pulse rate. The Oxi-27 goes a step further by also showing respiratory rate, a pulse waveform, and signal strength support, without making the device feel complicated.

That makes it a practical choice for two very different groups: home users who want simple regular check-ups from the comfort of their own home, and sports enthusiasts who like to check in before or after exercise. It also comes with a lanyard, so you can keep it nearby at home, in a wellness kit, or around your neck after a walk, workout, or breathing exercise when you’re ready to sit still and take a reading. 

A pulse oximeter is a helpful spot-check tool, but it does not replace medical advice. If you feel unwell or your readings concern you, contact a healthcare professional.

What Is a Pulse Oximeter?

A pulse oximeter is a small device that clips onto your fingertip. It uses light to estimate your blood oxygen saturation and pulse rate.

You may also see it called:

• an oximeter

• a finger pulse oximeter

• a fingertip pulse rate oximeter

• an oxygen saturation monitor

• a pulse oximeter for oxygen level checks

The iProven Oxi-27 is made for simple spot checks at home, after walks, or before and after exercise. 

Quick Answer: What Does the iProven Oxi-27 Measure?

Because the Oxi-27 goes beyond the most basic pulse oximeter readings, it gives you a fuller picture in one small fingertip device.

It measures:

• Oxygen saturation (SpO2): the percentage of oxygen in your blood

• Pulse rate: your heartbeats per minute

• Respiratory rate: your breaths per minute

• Pulse waveform: a simple moving graph that shows your pulse signal

• Perfusion index (PI): a signal-strength indicator, often related to finger placement

For most everyday users, the main readings to focus on are SpO2, pulse rate, and respiratory rate. The pulse waveform and PI are helpful extras, but you don’t need to study them every time.

Who the Oxi-27 Is Designed For 

For home wellness checks

The Oxi-27 is designed for people who want a pulse oximeter that feels clear, steady, and easy to use. The bright OLED display makes the numbers easy to see at a glance, and the fingertip design keeps the process simple.

It’s especially helpful for users who want an easy device to keep nearby for quick spot checks, without needing to scroll through confusing settings or read a complicated screen.

For sports and recovery routines

Sports enthusiasts may use the Oxi-27 before or after physical activity to check oxygen saturation, pulse rate, and respiratory rate while sitting still.

The lanyard is especially handy here: you can keep the device close after a walk, gym session, or breathing routine, then take a quick reading once you’ve settled.

The adjustable limits are also useful for people with naturally lower resting pulse rates, which is common among active users. You can adjust your limits so alerts feel more suited to your body.

The Main Readings, Explained Simply

Oxygen Saturation (SpO2)

SpO2 shows how much oxygen your blood is carrying. It appears as a percentage and is often the main number people look for when using a pulse oximeter.

If your oxygen saturation reading seems unusual, sit still, warm your hand, check your finger position, and try again. If the reading still concerns you, or if you feel unwell, contact a healthcare professional.

Pulse Rate

Pulse rate shows how many times your heart beats per minute.

This can be useful for both home users and sports users. For example, you may want to compare your pulse rate at rest versus after movement, or see how it changes during recovery.

Respiratory Rate

Respiratory rate shows how many breaths you take per minute.

This is one of the features that makes the Oxi-27 stand out from more basic oximeters. It gives extra breathing insights in the same small device, which can be helpful during rest, recovery, or breathing routines.

SpO2 and pulse rate appear quickly. Respiratory rate takes longer because the device needs more time to calculate your breathing pattern.

Pulse Waveform

The pulse waveform is the small moving graph on the display.

It may sound technical, but it simply shows that the device is picking up your pulse signal. A steady waveform can help you feel more confident that the device is reading properly.

Perfusion Index (PI)

Perfusion index, or PI, is a signal-strength indicator.

You do not need to focus on this number too much. It is often related to finger placement, finger warmth, and how strong the pulse signal is at the fingertip.

If the reading looks off, reposition your finger, keep still, and try again.

Easy to Read: The Bright OLED Display

A clear display matters, especially when a device is used at home by different people.

The Oxi-27 has a bright OLED display with clear numbers, making it easy to read during a quick spot check.

Practical tip: clip the Oxi-27 on your left index finger with your nail facing up. This naturally places the readings in an easy-to-view position for most users.

Adjustable Limits for More Personal Readings

Not everyone has the same usual pulse range. That’s why adjustable limits can be helpful.

For example, some sports users naturally have a lower resting pulse rate. With the Oxi-27, you can adjust your limits so the alert settings better match your personal range.

If you prefer to keep things simple, you can also use the device with the default settings. You don’t need to adjust every feature to benefit from the Oxi-27.

If you are unsure which limits are right for you, ask a healthcare professional for guidance.

How to Use the iProven Oxi-27 Correctly

For the best pulse oximeter reading, start with a calm hand and a good finger position.

Step-by-step

1. Sit down and relax your hand.

2. Warm your finger if your hands are cold.

3. Avoid nail polish, gel polish, or artificial nails when possible.

4. Place your finger fully inside the device.

5. Use your left index finger with the nail facing up for easy viewing.

6. Keep still while the device measures.

7. Read SpO2 and pulse rate after about 10 seconds.

8. Wait 60+ seconds for the respiratory rate to appear.

What can affect pulse oximeter readings?

A few common things can affect the reading:

• cold fingers

• movement

• poor finger placement

• nail polish, gel polish, or artificial nails

• poor circulation

• very bright surrounding light

If your oximeter reading looks unusual, rest for a moment, warm your hand, reposition your finger, and try again.

A Gentle Note on Readings

Pulse oximeters are helpful, but they should not be the only guide for health decisions.

For better readings:

• sit still

• keep your hand warm

• place your finger correctly

• repeat the reading if something seems unusual

Most importantly, pay attention to how you feel. If you feel short of breath, feel unwell, or your readings concern you, contact a healthcare professional.
