Apex MD300C19 - Fingertip Pulse Oximeter Manual

Safety information

The SpO₂ device is to be operated by trained personnel only.

Do not use the SpO₂ device in the presence of flammable anaesthetics, to prevent risk of explosion.

Do not use the SpO₂ device close to any Magnetic Resonance Imaging (MRI) device.

The SpO₂ readings and pulse signals can be affected by conditions of the environment, probe, and patient.

Do not open up the SpO₂ device except for the battery cover. The SpO₂ device is without any user-serviceable part inside and only qualified service personnel can perform maintenance service.

Do not expose the SpO₂ device to extreme moisture (such as rain) to ensure accurate performance and device safety.

If the accuracy of measurement by the SpO₂ device is uncertain, check the patient's vital signs by alternate means.

This device is intended only as an aid to patient assessment. It must be used in conjunction with clinical signs and symptoms.

Reposition the probe at least once every 4 hours to allow the patient's skin to breath.

The SpO₂ device is not intended for neonatal use.

Do not use the SpO₂ device with other devices (such as a blood pressure monitor cuff) that may interfere with blood flow and cause inaccurate measurement.

The SpO₂ device will be affected by electromagnetic interference during operation.

Please remove the batteries from the battery compartment if the device is not in use for a long period of time.

Introduction

The Fingertip pulse oximeter is to spot-check oxygen saturation in the blood (SpO₂) and the pulse rate. The pulse oximeter is for use on adults and children in hospitals, clinics, and/or at home.
The probe contains a dual light source (Red LED and Infrared red LED) and a photo detector. Bone, tissue, pigmentation, and venous vessels normally absorb a constant amount of light over time. The arteriolar bed normally pulsates and absorbs variable amounts of light during the pulsations. The ratio of light absorbed is translated into an oxygen saturation measurement (SpO₂). Because a measurement of SpO₂ is dependent on light from the probe, excessive ambient light can interfere with this measurement.
The wavelength of red LED is 660nm and Infrared LED is 905/880nm with a maximum optical output power of 4mW.
There is no visual or audio alarm.

Features

• Measures and displays reliable SpO₂ values and heart rate.
• Single turn-on key for easy operation.
• Bright LED display.
• Light, compact, and portable.
• Battery power is for 30 hours' continuous use.
• Powered by two alkaline AAA batteries.
• Device will turn off automatically after 8 seconds idle.

Product introduction

Operation

Open up battery compartment cover carefully and then install two "AAA" alkaline batteries according to the (+/-) polarity.
Press the "power switch" key for 1 second to activate the device. All icons appear on the LED screen.
The pulse bar with the "-" icon moving up and down on the screen means the measurement result will be ready soon.
The readings of oxygen saturation, pulse rate and pulse strength will appear on the LED screen in approximately 7 seconds after measurement. If the measurement fails, the icon "- -" will appear on the LED screen.
The device will turn itself off automatically after 8 seconds idle.
When the battery power is low, the LED icon will flash twice per second. Please replace the batteries as soon as possible or the device will turn off automatically.
