ABOUT PULSE OXIMETERS

A pulse oximeter is a non-invasive electronic device that estimates peripheral blood oxygen saturation (SpO₂) and measures pulse rate.

Most consumer pulse oximeters use a small sensor that clips onto a fingertip.

The device emits light through the finger and measures how different wavelengths are absorbed by oxygenated and deoxygenated blood.

Using this information, the device estimates the percentage of oxygen-saturated hemoglobin in the blood and displays a pulse rate.

At Coal Harbour Pharmacy, our Pulse Oximeters collection brings together selected digital monitoring devices for individuals seeking convenient oxygen saturation and pulse measurements.

Explore portable fingertip monitors, digital display models, and devices with additional monitoring features.

Pulse oximeters may be used as part of a healthcare professional’s monitoring plan for certain respiratory or cardiovascular conditions.

However, these devices have limitations and should not be relied upon to diagnose medical conditions or determine whether emergency care is necessary.

Important: Pulse oximeter readings are estimates. Accuracy can be affected by circulation, movement, nail polish, skin pigmentation, device quality, and other factors. Symptoms and clinical assessment remain essential.

CAUSES & APPROACHES TO OXYGEN MONITORING NEEDS

Respiratory Conditions

Certain lung conditions can affect the body’s ability to maintain adequate oxygen levels.

Monitoring Approach: Use pulse oximetry when recommended by a healthcare professional and follow an individualized action plan.

Chronic Obstructive Pulmonary Disease (COPD)

Some individuals with COPD require oxygen monitoring as part of ongoing care.

Monitoring Approach: Follow clinician-provided oxygen saturation targets rather than assuming standard values apply to everyone.

Respiratory Illness Recovery

Some respiratory illnesses may affect oxygen saturation.

Monitoring Approach: Use home monitoring only as directed and seek medical attention for concerning symptoms, even when readings appear normal.

High-Altitude Exposure

Oxygen saturation generally decreases as altitude increases.

Monitoring Approach: Consider measurements as supplementary information while remaining alert to symptoms of altitude illness.

Exercise & Physical Activity

Pulse rate and oxygen saturation may change during and after exercise.

Monitoring Approach: Use appropriate devices and measurement techniques. Consumer fingertip oximeters are not necessarily validated for accurate readings during movement.

Home Care Monitoring

Caregivers may assist individuals who have been advised to monitor oxygen saturation.

Monitoring Approach: Follow professional guidance for measurement frequency, interpretation, and escalation.

HOW TO READ PULSE OXIMETER RESULTS

A pulse oximeter typically displays two primary measurements.

SpO₂ – Blood Oxygen Saturation

SpO₂ estimates the percentage of hemoglobin carrying oxygen.

For many healthy adults at sea level, typical readings are approximately 95–100%.

However, expected values vary with altitude, health conditions, and individual circumstances.

Some people with chronic respiratory conditions have different prescribed oxygen saturation targets.

PR – Pulse Rate

Pulse rate is generally displayed in beats per minute (BPM).

A typical resting heart rate for many healthy adults is approximately 60–100 BPM, although athletes and other individuals may have lower resting rates.

Important Accuracy Considerations

Pulse oximeter measurements can be affected by:

• Poor Peripheral Circulation
• Cold Fingers
• Movement
• Nail Polish or Artificial Nails
• Skin Pigmentation
• Device Positioning
• Ambient Light
• Device Quality
• Certain Abnormal Hemoglobin Conditions

Important: Pulse oximeters may overestimate oxygen saturation in some individuals, including people with darker skin pigmentation. A normal-looking reading does not rule out low blood oxygen or serious illness.

COMMON PULSE OXIMETER CONCERNS

How Accurate Are Fingertip Pulse Oximeters?

Accuracy varies by device and operating conditions.

What May Help: Choose a device with appropriate regulatory authorization and published measurement specifications.

Is 95% a Normal Oxygen Level?

For many healthy adults at sea level, 95% may fall within the typical range.

What May Help: Interpret readings according to individual health circumstances and professional guidance.

Can a Pulse Oximeter Detect Breathing Problems?

It can estimate oxygen saturation but cannot identify every breathing problem.

What May Help: Pay attention to symptoms and seek medical assessment when appropriate.

Can a Pulse Oximeter Diagnose Sleep Apnea?

No. A standard fingertip pulse oximeter cannot independently diagnose sleep apnea.

What May Help: Seek an appropriate sleep evaluation if sleep apnea is suspected.

Why Do My Readings Change?

Readings may vary due to movement, circulation, finger temperature, device positioning, or physiological changes.

What May Help: Follow proper measurement techniques and assess repeated readings in context.

Can I Use a Pulse Oximeter During Exercise?

Some devices can provide measurements around physical activity, but movement may reduce accuracy.

What May Help: Review whether the specific device is intended for exercise-related monitoring.

HOW TO USE A FINGERTIP PULSE OXIMETER

Step 1: Read the Device Instructions

Follow the manufacturer’s directions for the specific model.

Step 2: Prepare Your Hands

Ensure your hands are warm and relaxed.

Remove nail polish or artificial nails if they interfere with measurement.

Step 3: Sit Comfortably

Rest quietly before taking a measurement when appropriate.

Step 4: Position the Device

Place the pulse oximeter on the recommended finger according to the manufacturer’s instructions.

Step 5: Remain Still

Avoid unnecessary movement while the device calculates the reading.

Step 6: Wait for a Stable Measurement

Allow the display to settle before recording the result.

Step 7: Record Results When Recommended

If following a monitoring plan, record SpO₂, pulse rate, time, and relevant symptoms.

Step 8: Follow Your Healthcare Action Plan

Use the thresholds and instructions provided by your healthcare professional.

Important: Seek emergency medical assistance for severe shortness of breath, blue or grey lips, chest pain, confusion, fainting, or other serious symptoms, regardless of the pulse oximeter reading.

For individuals without a personalized monitoring plan, a persistent reading of 92% or lower at sea level generally warrants urgent medical assessment. Readings around 88% or lower may indicate a medical emergency. These are not universal thresholds, particularly for people with certain chronic lung conditions or those at high altitude. Do not delay care while repeatedly checking the device.
