Vpod Instruction Manual

Chapter 1 Introduction
1.1 Brief Introduction
Thank you for purchasing the handheld pulse oximeter. The device is designed to measure SpO
2
and
PR, delivering visual and audio alarm, sensor off alarm. Please read this manual carefully before using
it.
Notice: The illustrations used in this manual may differ slightly from the appearance of the actual
product.
Measurement principle
The principle of pulse oximetry is based on the red and infrared (IR) light absorption of oxygenated
and deoxygenated hemoglobin present in the circulating blood. Oxygenated hemoglobin absorbs
more IR and allows more red light to pass through. Deoxygenated hemoglobin conversely absorbs
more red light and allows IR light to pass through. The detector probe is placed on the finger. The
probe contains two light emitting diodes (LED’s), one in the visible red spectrum. The beams of light
from this probe pass through the tissues and some light is absorbed by the blood and soft tissues
depending on hemoglobin concentration. The amount of light absorption at each light frequency is
dependent on the degree of oxygenation of hemoglobin within the tissues.
The microprocessor can select out the absorbance of the pulsatile fraction of blood, i.e. that due to
arterial blood, from constant absorbance due to non-pulsatile venous or capillary blood and other
tissue pigments
Basis of Operation
1. Red and Infrared-ray Emitter Diode
2. Red and Infrared-ray Receptor Diode
1.2 Safety Information
Conception of Warning, Precaution and Notice
Warning - Indicates a potential hazard or unsafe practice that, if not avoided, will result in
death or serious injury.
Precaution - Reminds the user to pay close attention to device operation, failure of which
may cause abnormal function of the instrument.
Notice - Informs the user of other important information by suggestion, requirement and
supplement.
Warnings
Please read this manual carefully before using this device. The user must check that the equipment
functions safely and ensure that it is in proper working condition before being used.
To avoid explosion hazard, do not use the oximeter in the presence of flammable anesthetics,
vapors or liquids.
Do not open the equipment housings; electric shock hazard may exist. All servicing and future
upgrades must be carried out by the personnel trained and authorized by our company only.
Do not use the pulse oximeter in an MRI or CT environment.
The pulse oximeter is specified for use by medical professionals only.
Prolonged use of the probe/sensor or the patient’s condition may require changing the sensor site
periodically. Change the sensor site and check skin integrity, circulatory status, and correct
alignment at least every 4 hours. Prolonged use may cause blisters, skin deterioration, and
discomfort.
Sensor malfunction may cause inaccurate data, possibly resulting in patient injury or death. Pay
close attention to the sensor and inspect it often.
