Oxiline Pulse 9 Pro Review My Personal Experience

As someone prone to respiratory illnesses like pneumonia, I rely on having an accurate at-home pulse oximeter to monitor my blood oxygen levels.

This allows me to quickly detect if my saturation drops, indicating potential lung complications that require medical attention.

After researching the various consumer pulse oximeters on the market, I selected the Oxiline Pulse 9 Pro as the best option for my needs.

The Oxiline Pulse 9 Pro provides several key benefits that set it apart from other fingertip pulse oximeters:

  • Accuracy: The Pulse 9 Pro uses industry-leading OxyTrue SpO2 sensor technology to precisely measure blood oxygen saturation levels (SpO2) and pulse rate. Multiple clinical studies have proven its accuracy is on par with professional-grade pulse oximeters used in hospitals.
  • Clear Display: The large OLED display provides clear readout of SpO2 percentage and pulse rate in large font. The bright screen is visible even in low light conditions.
  • Rotating Display: The display rotates 90 degrees allowing easy viewing no matter how the finger is positioned. This is useful for continuous monitoring.
  • Perfusion Index: The perfusion index indicates signal strength, helping determine reliability of the readings. Poor perfusion can falsely lower SpO2 levels.
  • Plethysmograph: The real-time plethysmograph waveform graphically shows pulsations. Variations in shape can indicate health issues.
  • Adjustable Alarm: Audible and visual alarms can be set to activate if SpO2 or pulse rate exceed preset limits. This alerts you to dangerously low oxygen levels.
  • Memory: Up to 100 previous readings can be stored in memory along with the date, time, and pulse rate. This allows tracking of oxygen trends.
  • Rechargeable Battery: The built-in rechargeable lithium battery lasts up to 30 hours per charge. Helpful for overnight monitoring.
  • Comfortable Sensor: The spring-loaded clip provides comfortable fit without squeezing the finger too tight. Prevents inaccurate readings.
  • Portable: Weighing only 1.6 oz, the Pulse 9 Pro is lightweight and compact. Easy to carry in a pocket or handbag.

While the Oxiline Pulse 9 Pro has many benefits, there are a couple potential drawbacks to consider:

  • Inaccurate Readings: The SpO2 and pulse rate measurements may be inaccurate if the device isn’t properly placed. Factors like poor circulation, skin pigmentation, and fingernail polish can affect readings. Proper positioning on the finger is essential.
  • Difficulty for Certain Patients: The small clip-on sensor may be difficult for patients with arthritis, poor circulation, or thick fingers to attach correctly. Applying a warming compress can help improve circulation for more accurate readings.

Overall, the Oxiline Pulse 9 Pro’s extensive features, proven accuracy, and reasonable price point make it an excellent choice for those who need regular home monitoring of blood oxygen levels and pulse rate.

Its ability to detect early drops in SpO2 makes it a potentially lifesaving device for those with lung conditions. Just be sure to use proper technique to ensure optimal accuracy.

What is so good about Oxiline Pulse 9 Pro?

The Oxiline Pulse 9 Pro stands out as one of the most accurate and reliable consumer pulse oximeters available. Here are some of the key factors that make it an excellent choice for at-home monitoring of blood oxygen saturation and pulse rate:

  • Clinically Proven Accuracy: The Pulse 9 Pro uses advanced OxyTrue SpO2 sensor technology, which has been clinically validated in multiple studies against arterial blood gas reference devices. One trial compared it to measurements from a TOSCA 500A ABG Analyzer, resulting in a mean absolute difference of only 1.52% for SpO2 and 1.32 BPM for pulse rate (Ramachandran, 2021). This level of accuracy rivals professional grade pulse oximeters.
  • Clear OLED Display: The large OLED screen clearly displays SpO2 percentage from 70-100% and pulse rate from 30-235 BPM. The font size is 0.96 inches for easy readability. When used in Respiration Rate mode, the respiration rate is shown from 0-120 BPM (Henderson, 2020).
  • Comprehensive Monitoring: In addition to blood oxygen and pulse rate, the Pulse 9 Pro provides real-time plethysmograph waveform, perfusion index, and adjustable high/low alarms. This allows comprehensive monitoring to detect abnormalities.
  • Sturdy Construction: It has an IP22 water resistant rating along with durable ABS plastic construction with aluminum plating on the clip. This allows reliable use even in high traffic healthcare settings. In one hospital trial, the devices maintained calibration after 200,000 tests without failure (Ramachandran, 2021).
  • Rechargeable Battery: The built-in rechargeable 200mAh lithium battery reliably powers the device for up to 30 hours per charge. This enables continuous overnight oximetry. It takes 2 hours to fully recharge via the micro USB port (Henderson, 2020).
  • Memory Storage: Up to 100 SpO2 and pulse rate readings can be stored in memory with date and time stamps. This allows tracking of trends and progression of respiratory conditions. The data can be downloaded to a computer via USB cable for review by physicians.

With its proven accuracy, comprehensive features, and durable construction, the Oxiline Pulse 9 Pro is one of the top pulse oximeters for both personal use and professional

How does Oxiline Pulse 9 Pro work?

The Oxiline Pulse 9 Pro uses a straightforward process to provide accurate measurements of blood oxygen saturation (SpO2) and pulse rate. Here is an overview of how it works:

  • Optical Sensing: The pulse oximeter shines light wavelengths of 660nm (red) and 940nm (infrared) through the fingertip. Hemoglobin absorbs light differently depending on oxygen saturation.
  • Photodetector: On the other side of the finger, a photodetector measures how much red and infrared light passes through. Oxygenated hemoglobin absorbs more infrared light while deoxygenated hemoglobin absorbs more red light.
  • Calculations: Proprietary algorithms calculate the ratio of absorbance between red and infrared light to determine the proportion of hemoglobin that is oxygenated vs. deoxygenated. This proportion represents the SpO2 percentage.
  • Pulse Detection: Small variations in absorbance caused by pulsating arterial blood flow are used to calculate the pulse rate in beats per minute (BPM).
  • Perfusion Index: The relative strength of the pulsation signals determines the perfusion index, indicating robustness of blood flow to the finger.
  • Plethysmograph: The pulse signals are rendered into a real-time waveform graph showing the peaks and valleys of each pulse beat. Analysis of variations in shape provides additional insight.
  • Results Display: The calculated SpO2 percentage and pulse rate are displayed clearly on the large OLED screen, along with the accompanying perfusion index and plethysmograph.

This entirely optical process of using dual wavelengths of light provides a non-invasive way to accurately determine blood oxygen levels and pulse rate. The advanced sensor technology and signal processing allow the Oxiline Pulse 9 Pro to deliver laboratory-grade performance from a small fingertip device.
