Fingertip Pulse Oximeter
USER MANUAL
Ver1.0 – iP900AP
General Description
SpO2 stands for peripheral capillary oxygen saturation. Oxygen saturation is defined as the ratio of oxyhemoglobin (HbO2) to the total concentration of hemoglobin (i.e. Oxyhemoglobin + reduced hemoglobin) present in the blood. It is an important physiological parameter involved in respiration and circulation. The Pulse Oximeter feature herein is small, portable, non-invasive and easy to use. The user only needs to insert a finger into the chamber to measure his/her SpO2 level and pulse rate. It has also been proven to be highly precise and reliable in clinical tests.
Measurement Principle
Oxygenated blood absorbs light preferentially at 905nm (near infrared light), whereas deoxygenated blood absorbs light preferentially at 660nm (red light). A pulse oximeter works by passing a beam of red and infrared light through a pulsating capillary bed and then measure the amount of red and infrared light emerging from the tissues via a sensor. To improve accuracy, the iP900AP uses a proprietary algorithm to collect data from pulsatile arterial blood and excludes noise from the tissues. The relative absorption of light by oxyhemoglobin (HbO) and deoxyhemoglobin is then calculated according to the Beer-Lambert’s law and a quantitative measurement of the users’ oxyhemoglobin status i.e. Oxygen saturation level (SpO2) is derived.

- Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.
- This equipment complies with IEC 60601-1-2:2007 for electromagnetic compatibility for medical electrical equipment and/or systems. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise in healthcare and other environments, it is possible that high levels of such interference due to close proximity or strength of a source might disrupt the performance of this device.
- Portable and mobile RF communications equipment can affect medical electrical equipment.
- Do not disassemble, repair or modify the equipment.
- It may be unsafe to
–use accessories, detachable parts and materials not described in the instructions for use

Intended Use
The iP900AP Fingertip pulse oximeter is a portable non-invasive device intended for spot-checking of oxygen saturation of arterial hemoglobin (SpO2) and pulse rate of children (>12 years old) and adult. The device is for sports and/or aviation use.
Operation Instructions
- Install two AAA batteries according to the Battery Installation instructions.
- Place one of your fingers into the finger chamber of the pulse oximeter.
- Press the power button on the front panel to turn the pulse oximeter on.
- Keep your hand and finger still for the reading. It is recommended that you do not move your body while taking a reading.
- Read the data from the display screen.
- Press (<1 sec) the button again to toggle between six display modes (see below).
After turning the oximeter on, each time you press the power button, the oximeter will switch to another display mode. There are 6 display modes shown as follows:
Tips to getting a good reading
- Make sure that your finger is inserted deep into the chamber so that the fingertip is placed directly in between the LED sensor and the LED light source.
- Avoid making any body movement, especially your finger while taking measurement.
- Long fingernails may obstruct the light sensor and prevent accurate measurement. Please keep the fingernails short while using the device.
- Excessive ambient infra-red light, especially in an overly bright lit room, can interfere with the sensor, preventing an accurate measurement.
- Poor blood circulation can affect oximeter readings. Warm your hands and fingers before taking your measurements. Note that the pulse oximeter is measuring your SpO2 and PR based on your blood flow. If the blood flow in your finger drops below a perfusion index of 0.3, the pulse oximeter will not be able to get a reading.
- Some people with medical conditions such as anemia, hypotension and hypothermia may experience an inaccurate reading during use. In such case, we suggest that you consult a physician.
Front Panel
The pulse bar graph, plethysmograph and perfusion index (PI) are useful features that can be used to determine the reliability of a reading. If the height of the pulse bar is less than 30%, this indicates signal inadequacy and the displayed SpO2 or pulse rate value is potentially incorrect. Adjust your finger so that it is directly between the LED lights and sensor.
The plethysmograph indicates the amount of blood flow detected by the pulse oximeter and the perfusion index indicates the strength of your pulse. Each wave in the plethysmograph corresponds to a heartbeat and the wave amplitude corresponds to the amount of blood detected by the pulse oximeter. The pulse oximeter is optimized when the height of the wave amplitude is consistent throughout as shown in the figure above. That is when you should take the reading. The pulse oximeter can function with a PI reading as low as 0.3%. If your PI is below 0.3%, this means that your blood perfusion is too low for a reliable read. Warm your hands to increase blood flow and retake your measurement. In general, a higher PI will give you a more reliable reading.
