The Dr Trust USA Fingertip Pulse Oximeter 218 is a compact digital health-monitoring device designed to measure blood oxygen saturation (SpO₂) and pulse rate through a fingertip. Its large OLED display provides an easy-to-read view of measurements, making it suitable for home monitoring and everyday health tracking.
The multidirectional OLED screen can display SpO₂, pulse rate, perfusion index, pulse waveform and battery status. The display can be viewed from different directions, which can be particularly convenient when the device is being used by another person or monitored by a caregiver.
The pulse oximeter operates using 2 AAA batteries and features automatic power-off to help conserve battery life. Its compact construction and included lanyard make it convenient to carry for travel, outdoor activities or routine monitoring at home. It also has an IP22 water-resistance rating, meaning it can tolerate limited exposure to water splashes but should not be submerged.

Frequently Asked Questions
1. What does the Dr Trust Pulse Oximeter 218 measure?
It is designed to measure SpO₂ (blood oxygen saturation) and pulse rate through a fingertip sensor. It also displays parameters such as perfusion index and pulse waveform.
2. Is the Dr Trust 218 suitable for home use?
Yes. Its compact fingertip design and simple operation make it suitable for routine home health monitoring.
3. Does the pulse oximeter require charging?
No. The device operates using 2 AAA batteries, which are included with the product.
4. Does it show the pulse waveform?
Yes. The OLED display provides a pulse waveform along with SpO₂, pulse rate, perfusion index and battery information.
5. Can the display be viewed from different directions?
Yes. The device features a multidirectional OLED display designed to make readings easier to view from different angles.
6. Is the Dr Trust 218 waterproof?
No. It has an IP22 water-resistance rating, but it should not be submerged or exposed to significant amounts of water.
7. Can children use this pulse oximeter?
The manufacturer describes the device as accommodating a wide range of finger sizes, but this model should not automatically be treated as a dedicated pediatric oximeter. For children, select a device appropriate for the child's age and finger size and follow medical advice where required.
8. Can I use this pulse oximeter while exercising?
The manufacturer lists activities such as biking, skiing, mountain climbing and aviation among its application areas. However, movement can affect pulse-oximeter readings, so measurements are generally more useful when the finger and hand are kept still.
9. Does the pulse oximeter diagnose health conditions?
No. A pulse oximeter provides measurements that can support health monitoring but should not be used as a standalone diagnostic device. Abnormal readings should be considered alongside symptoms and professional medical advice.
10. What warranty is provided?
The manufacturer's current page states warranty coverage subject to its terms and conditions. It also specifies registration requirements for the extended warranty and exclusions for issues such as accidental damage, water damage, misuse and unauthorised repairs. Customers should verify the warranty terms applicable to their invoice at the time of purchase.
