LPOW A340 Fingertip Pulse Oximeter Manual

How to use

This device is intended for noninvasive spot-checking your blood oxygen saturation levels and pulse rate.

The device will automatically shut down for longer than 16 seconds after finger is removed from the chamber.
* Please refer to the manual for detailed operation of the Display Switching & Parameter Setting.

Safety

Instructions for the Safe Operation and Use of the Fingertip Pulse Oximeter

• Do not attempt to service the Fingertip Pulse Oximeter. Only qualified service personnel should attempt any needed internal servicing.
• Prolonged use or the user's condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status and correct alignment at least every 2 hours.
• SpO2 measurements may be adversely affected in the presence of high ambient light. Shield the sensor area with a surgical towel, or direct sunlight, for example) if necessary.
• The following reason will cause interference to the testing accuracy of the Fingertip Pulse Oximeter.
• High-frequency electrosurgical equipment.
• Placement of a sensor on an extremity with a blood pressure cuff arterial catheter, or intravascular line
• The user has hypotension severe vasoconstriction severe anemia or hypothermia.
• The user is in cardiac arrest or is in shock.
• Fingernail polish or false fingernails may cause inaccurate SpO2 readings.

Introduction

General

This chapter provides a general description of the Fingertip Pulse Oximeter including:

• Brief device description
• Product features

Indication for use/ intended use

The Pulse Oximeter is a non-invasive device intended for spot checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). This portable device is indicated for sport and aviation use, not in clinical institution.

Brief Device Description

The Fingertip Pulse Oximeter, based on all digital technology, is intended for noninvasive spot-check measurement of functional oxygen saturation of arterial hemoglobin (SpO2). Advanced DSP algorithm* can minimize the influence of motion artifact and improve measurement accuracy of low perfusion*. The Oximeter can be used to measure human Hemoglobin Saturation and heart rate through finger. The product is suitable for family, sport, aviation and etc.

Product Features

• Lightweight for carrying and Easy-To-Use.
• Color OLED display, simultaneous display for testing value and plethysmogram*.
• Low Perfusion: 0.3%. (Advanced DSP algorithm can improve measurement accuracy, under the condition of low perfusion.)
• Visual & Sound reminder function. Real-time spot-checks.
• Low Battery voltage indicator.
• Automatically switch off.
• Standard two AAA 1.5V Alkaline Bаttеrу support more than 20 hours continuous work.

*DSP algorithm: Digital signal processor algorithm.
*Low Perfusion: In physiology, perfusion is the process of a body delivering blood to a capillary bed in its biological tissue. Under the condition of low perfusion, the measurement of non-invasive saturation of pulse-blood oxygen is low-accurate.
*Plethysmograph: is an instrument for measuring changes in volume within an organ or whole body (usually resulting from fluctuations in the amount of blood or air it contains).
PI (Perfusion Index )is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a body's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site.

Installation, Setup, and Operation

Description of the Front Panel

(as figure 3.1.1)

Table 3.1.1 Part Definition and Description

Display

After switch on, the OLED display of the Fingertip Pulse Oximeter is as follows:

Parameter setting

When the device is under measuring interface, press the select button for 1 second in order to enter into menu page (figure 3.3.1 and figure 3.3.2 ). There are two submenus for choice:

Remind Setup

Press the select button for 1 second and enter into the Remind Setup menu. User can adjust the setting through moving the "*" symbol to the back of the Sound Reminder, Beep, Restore or Brightness.

• Sound Reminder
  Press the select button to move the "*" symbol to the back of Sound Reminder, long press the select button to turn it on/off.
  (Note: If the measured value exceeds the maximum or minimum value of SPO2 or PR, there will give off sound when sound reminder is turned on.)
• Beep
  Press the select button to move the "*" symbol to the back of Beep, long press the select button to turn it on/off.
  (Note: When Beep is turned on, the sound emitted during the test indicates the pulse rate sound)
• Restore
  When the "*" symbol show behind "Restore", long press the select button can be changed to "OK", which causes the device to restore factory data setting.
• Demo
  Press the select button to move the "*" symbol to the back of Demo, long press the select button to turn it on/off.
• Brightness
  When the "*" symbol show on "Brightness", long press the select button to change the Brightness value from 1 to 5.

Limit Value Setting

When the * symbol show on the Reminder Setup, long press the select button until enter into the Remind Limit setup menu (figure 3.3.2). User can press the select button to select the items. And press the select button for 1 second to change the data you need.
On the Reminder Limit setup menu page (figure 3.3.2), when the * symbol show behind the "+/-". Press select button for 1 second to change the "+" to "-" or change the "-" to "+".
When "+" shows on the right side, move the "*" after the Spo2 Hi or PR Hi setting and long press the select button for 1 second can increase the value to a higher value (until it reaches to the highest.)
When "-" shows on the right side, move the "*" after the Spo2 Lo or PR Lo value setting and long press the select button for 1second can reduce the value to a lower value (untill it reaches to the lowest).

Note:

1. The sound reminder have 1 second delay after the incorrect result being detected.
2. The customer can preset the limit value to the 98 or 99 to check whether it is normal for sound reminder setting.

Operation

Install battery

Installing two AAA batteries into battery cassette in correct polarities and cover it.

Turn the Fingertip Pulse Oximeter on

Put one of fingers into rubber hole of the Oximeter (it is best to put the finger thoroughly) with nail surface upward, then releasing the clamp.
Press power button to turn the Fingertip Pulse Oximeter on.

Read correspondent data from display screen.

Display Description of OLED

It is shown as below:

Note:

1. when battery power is at lowest level, the battery capacity indicates symbol of "" in OLED, remind users of replacement of battery.
2. The plethymogram can been regarded as correct if the wave is fluctuated regularly.

Cleaning and Disinfection

Cleaning

Switch off the power and take out the batteries before cleaning, Keep the exterior surface of the device clean and free of dust and dirt. Cleaning exterior surface (OLED display screen included) of the unit with a dry and soft cloth. Use 75% density of medical alcohol to clean the surface and use dry fabric with little alcohol to avoid alcohol permeates into the device.

Disinfection

Disinfecting the machine after using by mutiple users.
Use 75% density of medical alcohol to clean the surface that contacting with the users.

Maintenance

• Replace the batteries timely when battery indication is low. Clean surface of thе Pulse Oximeter before it is used in diagnosis for user.
• Remove the batteries inside the battery cassette if the Oximeter will not be operated for a long time.
• It is better to preserve the product in a place where ambient temperature is –25°C to 55°C (-13℉-131℉) and humidity is 15%-93%.
• Regular inspection to make sure that no obvious damage existed to affect the safety and performance of device.
• No flammable substance, overtop or lower temperature and humidity existed in operation conditions.
