# Dr Trust USA Pulse Oximeter 218 | SpO₂, Pulse Rate & PI Monitor

## Dr Trust USA Pulse Oximeter 218 | SpO₂, Pulse Rate & Perfusion Index Monitor

**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.

## What Does Dr Trust Oximeter 218 Measure?

The Dr Trust 218 displays three useful monitoring parameters:

### SpO₂ – Blood Oxygen Saturation

SpO₂ represents the percentage of haemoglobin in arterial blood estimated to be carrying oxygen.

### Pulse Rate

Pulse rate indicates the number of heart beats detected per minute.

### Perfusion Index – PI

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.

* * *

## Bright Multidirectional OLED Display

Model 218 uses a large, bright **OLED display** designed to make readings easy to view.

The screen can display:

-   SpO₂
-   Pulse rate
-   Perfusion Index
-   Pulse waveform
-   Pulse bar graph
-   Battery status

The multidirectional display allows results to be viewed more conveniently by either the user or caregiver.

* * *

## Adjustable Display Brightness

The OLED screen includes adjustable brightness to help improve visibility under different lighting conditions.

This may be useful when measuring in:

-   Bright daylight
-   Indoor lighting
-   Lower-light environments
-   Home-care settings

* * *

## Easy Fingertip Operation

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:

-   Keep the hand relaxed
-   Remain still during measurement
-   Keep the finger warm
-   Avoid excessive movement
-   Make sure the finger is inserted correctly

* * *

## Automatic Power-Off

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.

* * *

## Powered by 2 AAA Batteries

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.

* * *

## IP22 Water-Resistant Design

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:

-   Immerse the oximeter in water
-   Wash it under running water
-   Use it while wet
-   Store it in excessively damp conditions

* * *

## Compact & Portable

The lightweight fingertip format makes the Dr Trust 218 convenient for:

-   Home monitoring
-   Travel
-   Caregiving
-   Sports and fitness monitoring
-   High-altitude activities
-   Routine pulse and oxygen checks

A pulse oximeter should not replace professional clinical assessment when symptoms are significant or worsening.

* * *

## Tips for More Reliable Oximeter Readings

Pulse oximeter readings can be affected by measurement conditions.

For better consistency:

-   Keep the finger warm
-   Remain still during measurement
-   Avoid measuring immediately after vigorous exercise
-   Ensure correct fingertip placement
-   Avoid excessive external light on the sensor
-   Remove nail polish or artificial nails if they interfere with detection
-   Wait for the displayed values to stabilise

* * *

## What Can Affect a Pulse Oximeter Reading?

Factors that may influence SpO₂ readings include:

-   Cold fingers
-   Poor peripheral circulation
-   Movement
-   Incorrect finger placement
-   Nail polish
-   Artificial nails
-   Very strong ambient light
-   Weak pulse signal

If a reading appears inconsistent with the person's condition, repeat the measurement carefully and seek appropriate medical evaluation when needed.

* * *

## SpO₂ & Pulse Rate Monitoring at Home

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:

-   Symptoms
-   Medical history
-   Altitude
-   Measurement quality
-   Professional medical advice

## Warranty – Important Clarification

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.
