1. Product Overview
1.1 Application background
The handheld vital signs monitor integrates blood oxygen measurement, end-expiratory
carbon dioxide monitoring, body temperature monitoring and other functions. It uses a color
display to display blood oxygen saturation, pulse rate, EtCO2, respiration rate, body
temperature, and system information. , And error messages (prompts such as falling off of
each parameter measuring probe) and alarm messages.
a Principle of pulse oximetry
Firstly, the difference between the absorption of red light and infrared light by
oxyhemoglobin and reduced hemoglobin (as measured by spectroscopic measurement);
secondly, the flow of arterial blood in the tissue is determined by the pulse (as recorded by
hematogram). ) Change when pulsating. The pulse oximeter adds red light and infrared
light to the arteries and measures the changes in light absorbed during the pulse cycle to
determine SpO2. Low-pressure red and infrared light-emitting diodes (LEDs) in the blood
oxygen probe are used as light sources, and photodiodes are used as light detectors.
Oxyhemoglobin and reduced hemoglobin absorb different light. The amount of red light and
infrared light absorbed by blood is related to the oxygen saturation of hemoglobin. In order
to identify the oxygen saturation of arterial hemoglobin, the oximeter uses the pulsating
characteristics of arterial blood flow. During systole, new arterial blood enters the ventricle,
blood volume and light absorption increase; during diastole, blood volume and light
absorption reach their lowest point. The SpO2 measurement of the oximeter depends on
the difference between the maximum and minimum absorption (eg, measured during
systole and diastole). In this way, the light absorbed by the arterial blood pulsation is the
focus of the problem. It is necessary to eliminate non-pulsatile absorption such as the
absorption effect of tissues, bones and venous blood. The vital signs monitor uses a
photodetector to measure SpO2 and pulse rate through two wavelengths of red light and
infrared light through human tissue. During the measurement, the color and thickness of
the human tissue, the position of the probe, the brightness of the light source, and the
absorption of blood in the arteries and veins of the human tissue affect the result of the
signal strength.

b End-breathing carbon dioxide concentration (EtCO2)
Human tissue cells produce CO2 through metabolism, which is then transported to the
lungs through capillaries and veins through the body, and is excreted from the body during
exhalation. In this process, the inhaled oxygen is transported by hemoglobin in the blood,
and the CO2 produced in the human body is dissolved in the blood and brought out by
ventilation. According to the law of gas diffusion, CO2 diffuses from high-concentration
areas to low-concentration areas. Therefore, CO2 diffuses from pulmonary blood vessels
(high-concentration areas) to alveoli (low-concentration areas), and then is discharged from
the lungs.
The carbon dioxide monitor adopts infrared monitoring technology. This method is based
on the principle that the absorption rate of infrared light is related to the concentration of
carbon dioxide when the infrared light passes through the gas sample to be tested: CO2
mainly absorbs infrared light with a wavelength of 426nm, which attenuates the infrared
beam, and its attenuation degree It is proportional to the concentration of CO2. When
infrared rays pass through the gas, the CO2 in the gas will absorb part of the infrared rays
and weaken the remaining infrared signal strength. By measuring the initial infrared
intensity and the infrared intensity after the exhalation passes, the CO2 component exhaled
by the patient is calculated, that is, the end-tidal carbon dioxide (EtCO2). details as follows:
The invisible infrared light emitted by the passed infrared light source passes through the
airway adapter, and the respiratory airflow flows in the airway adapter. When the light beam
passes through the airway adapter, some of the light is absorbed by the gas mixture. The
absorbed light beam reaches the infrared detector fixed at the other end. The infrared
detector converts the light beam into an electrical signal. The electrical signal is converted
into a digital value by the ADC and sent to the microprocessor. The microprocessor will

calculate the carbon dioxide concentration in the breathing gas mixture based on the ratio
of the light of the two measurement channels.

Reasons for the
increase in EtCO2
The depth of anesthesia is not enough, and the patient
has pain and tremor;
Insufficient ventilation
Upper respiratory tract obstruction;
Repeat breathing
The mechanical void increases.
Reasons for the
decrease of EtCO2
value
Pulmonary embolism;
Hyperventilation
The ventilation system is leaking.
4.3.5. If the patient exercises, the following measures can be used to remedy:
Check whether the probe position is correct;
