Dr Trust USA Pulse Oximeter 218 is a compact fingertip monitoring device designed for non-invasive measurement of blood oxygen saturation (SpO₂), pulse rate and perfusion index (PI).
The oximeter uses a fingertip photoelectric sensor and displays results on a bright multidirectional OLED screen with adjustable brightness. In addition to SpO₂ and pulse rate, the display can show perfusion index, pulse waveform, pulse-rate bar graph and battery status.
Its lightweight design, simple fingertip operation, automatic power-off and included AAA batteries make Model 218 suitable for routine home monitoring and portable use.
Brand: Dr Trust USA
Model: 218
Product Type: Fingertip Pulse Oximeter
The Dr Trust 218 displays three useful monitoring parameters:
SpO₂ represents the percentage of haemoglobin in arterial blood estimated to be carrying oxygen.
Pulse rate indicates the number of heart beats detected per minute.
Perfusion Index reflects the strength of the pulse signal detected at the measurement site.
PI can help the user understand whether the fingertip signal is relatively strong or weak during a measurement.
Model 218 uses a large, bright OLED display designed to make readings easy to view.
The screen can display:
The multidirectional display allows results to be viewed more conveniently by either the user or caregiver.
The OLED screen includes adjustable brightness to help improve visibility under different lighting conditions.
This may be useful when measuring in:
The Dr Trust 218 is designed for straightforward use.
Insert a finger fully into the sensor clip and remain still while the device obtains the reading.
For more consistent results:
The oximeter automatically powers off when not in use, helping conserve battery life.
This feature is useful for a portable device that may be used intermittently throughout the day.
Model 218 is powered by 2 AAA batteries.
The official Dr Trust listing states that batteries are included with the product.
A battery-level indicator on the OLED screen helps users monitor remaining power.
The Dr Trust 218 is described as IP22 water resistant.
This means it is designed to tolerate limited accidental splashing during normal use.
It is not waterproof.
Do not:
The lightweight fingertip format makes the Dr Trust 218 convenient for:
A pulse oximeter should not replace professional clinical assessment when symptoms are significant or worsening.

Pulse oximeter readings can be affected by measurement conditions.
For better consistency:
Factors that may influence SpO₂ readings include:
If a reading appears inconsistent with the person's condition, repeat the measurement carefully and seek appropriate medical evaluation when needed.
A fingertip pulse oximeter can be used to monitor oxygen saturation and pulse rate conveniently at home.
It may be useful for users who have been advised by a healthcare professional to monitor oxygen levels or pulse trends.
A single oximeter reading should not be interpreted without considering:
| Feature | Dr Trust 218 | Basic Oximeter |
|---|---|---|
| SpO₂ | Yes | Usually yes |
| Pulse Rate | Yes | Usually yes |
| Perfusion Index | Yes | Model dependent |
| Pulse Waveform | Yes | Not always available |

The current official Dr Trust Model 218 product page contains two different warranty statements.
The product-description section refers to an extended warranty of up to 6 months when registered on the manufacturer's website within 15 days, while another warranty section on the same page currently states 1 year.
Because these statements are inconsistent, Microsidd recommends checking the current warranty card, sealed product packaging and Dr Trust / Nureca warranty-registration terms applicable to the unit supplied.
Manufacturer warranty generally applies to eligible manufacturing defects and is subject to exclusions such as accidental damage, drops, water damage, misuse, wear and tear and unauthorised repair.
Pulse oximeters can appear similar while differing in brand, model, PI display, screen quality, waveform display, water resistance and warranty support.
