Monitoring parameters

ECG

Electrocardiogram is one of the most basic monitoring items of monitoring instruments. ECG signals are obtained through electrodes. Monitoring electrodes are disposable AS-AGCI button electrodes.

Heart rate

Heart rate refers to the number of heart beats per minute. Heart rate measurement is based on the electrocardiogram waveform to determine the instantaneous heart rate and average heart rate.

Healthy adults have an average heart rate of 75 beats / min in a quiet state, and the normal range is 60-100 beats / min. Under different physiological conditions, the heart rate can be as low as 40-50 beats / min and up to 200 beats / min.

Monitor heart rate alarm range: low limit 20-100 times / min, high limit 80-240 times / min.

Breathe

Breathing refers to the respiratory frequency of the monitored patient, that is, the respiration rate. Breathing frequency is the number of times a patient breathes in a unit of time, in minutes.

When breathing calmly, the newborn is 60-70 times / min and the adult is 12-18 times / min.

There are two measurement methods for respiratory monitoring: thermal and impedance

Thermistor respiration measurement is to place a thermistor at the nostril. When the airflow passes through the thermistor, the thermistor is subjected to heat exchange by the flowing airflow, and the resistance value changes, thereby measuring the frequency of breathing.

Impedance breathing measurement is based on the alternating relaxation of the chest arm muscles, the thoracic frame is also deformed alternately, and the electrical impedance of the body tissue is also altered alternately. There is a certain relationship between respiratory impedance (pulmonary impedance) and lung volume. Lung impedance varies with the lung. The capacity increases. Impedance respiration measurement is designed according to changes in lung impedance.

In monitoring measurement, the respiratory impedance electrode and the ECG electrode are used together, that is, the ECG electrode is used to simultaneously detect the ECG signal and the respiratory impedance.

Invasive blood pressure

Invasive blood pressure refers to the central venous pressure, left atrial pressure, cardiac output, and cardiac floating catheter of the monitored patient.

Central venous pressure refers to the thoracic venous pressure or right atrium. It can reflect the entire venous return more than the local venous pressure. The normal person is 6.7-10.7KPA, and the heart failure patients can reach 22.7KPA.

The central venous pressure is measured by inserting a venous catheter from the jugular vein and femoral vein, measuring the central venous pressure at the junction of the superior vena cava and the right atrium through the great vein.

Left atrial pressure can indicate the capacity of the left ventricle to fill and discharge, left ventricular failure, left ventricular right ventricular ventricular volume decreases, left atrial pressure increases, can cause pulmonary congestion and emphysema, but cardiac output also increases. Therefore, monitoring and maintaining proper left atrial pressure are extremely important for maintaining cardiac output.

Left atrial pressure is measured by inserting a cardiac catheter into the pulmonary artery and measuring the pulmonary artery pressure to indirectly determine the left atrial pressure, or through the junction of the left upper pulmonary vein and the left atrium, and directly inserting the cardiac catheter into the left atrium.

Non-invasive blood pressure

Non-invasive blood pressure monitoring uses the Korotkoff sound detection method, which blocks the brachial artery with an inflatable cuff. A series of sounds with different tones appear during the pressure drop at the obstruction end. According to the tone and time, the systolic and diastolic pressures can be judged as Korotkoff sound.

During monitoring, the microphone is used as a sensor. When the cuff pressure is higher than the systolic pressure, the blood vessel is squashed, the blood under the cuff stops flowing, and the microphone has no signal. When the microphone detects the first off sound, the pressure corresponding to the cuff is the systolic pressure. The microphone then measures the Koto sound from the sound reduction stage to the silent stage, and the pressure corresponding to the cuff is the diastolic pressure.

Cardiac output

Cardiac output is an important indicator of heart function. Under certain pathological conditions, cardiac output is reduced, which makes the body's nutritional supply insufficient. Cardiac output is the amount of blood ejected by the heart per minute. Its measurement is to inject a certain amount of indicator into the blood by a certain method. After diffusion in the blood, the change of the indicator is measured to calculate the cardiac output.

There are two methods for measuring cardiac output: FICK method and thermal dilution method.

The FICK method uses oxygen as an indicator in the open blood circulation. Since the amount of oxygen exchange between the pulmonary capillaries and the alveoli is proportional to the pulmonary blood flow, the cardiac output can be measured by measuring the oxygen concentration of the pulmonary arteries and pulmonary veins.

The thermal dilution method uses cold saline as an indicator, and a Swan-Ganz floating catheter with a thermistor as a cardiac catheter. The thermistor is placed in the pulmonary artery and cold saline is injected into the right atrium to calculate the cardiac output.

Body temperature

Body temperature reflects the results of the body's metabolism and is one of the conditions for the body to perform normal functional activities. The temperature inside the body is called "core temperature" and reflects the condition of the head or torso. It is generally measured from the mouth, armpits and rectum. Statistics from the Chinese show that the oral cavity temperature is 36.7-37.7 degrees, the armpit temperature is 36.9-37.4 degrees, and the rectal temperature 36.9-37.9 degrees.

Pulse

The pulse is a phenomenon in which arterial blood vessels periodically pulsate with the expansion and contraction of the heart. The pulse includes changes in various physical quantities such as the internal pressure, volume, displacement, and wall tension of the blood vessel.

Photoelectric volumetric pulse measurement is the most common in monitoring measurement. The sensor is composed of a light source and a photoelectric transducer, which is clamped on the fingertip or auricle of the patient. The light source selects a certain wavelength that is selective for oxyhemoglobin in arterial blood. It is best to use a light-emitting diode with a spectrum of 6 * 10-7 * 10M. This light passes through the peripheral blood vessels of the human body

When the volume of pulse congestion changes, the transmittance of this beam of light is changed, and the light transmitted or reflected by the tissue is received by the photoelectric transducer, which is converted into an electrical signal to be amplified and output by the amplifier, thereby reflecting the volume change of the arterial blood vessel.

The pulse is a signal that changes periodically with the pulsation of the heart, the volume of the arteries and blood vessels also changes periodically, and the signal change period of the photoelectric transducer is the pulse rate.

Blood gas

Blood gas monitoring mainly refers to partial pressure of oxygen (PO2), partial pressure of carbon dioxide (Pco2) and blood oxygen saturation (Spo2).

Oxygen and carbon dioxide exist in the blood in two states of physical dissolution and chemical combination. It is precisely because of the chemical combination that the blood's ability to transport O2 and Co2 is greatly improved.

Po2 is a measure of the amount of oxygen in arteries. Pco2 is a measure of the amount of carbon dioxide in venous vessels.

In the transportation of O2, O2 and hemoglobin are mainly present in the red blood cells in a combined form, and the amount of lysis is very small. Therefore, the maximum amount of hemoglobin bound oxygen per 100ml of blood is called Oxygen Content (OCP). Measure the oxygen content (Oxygen Content, OCN).

Blood oxygen saturation is the ratio of oxygen content to oxygen capacity.

The monitoring of blood oxygen saturation is also measured by the photoelectric method, and the sensor and the pulse measurement are the same. When Po2 is high in blood, the blood is bright red, and when Po2 is low, the blood is dark red. The photoelectric converter has a low-pass characteristic. When light passes through different Po2 blood, the photoelectric converter accepts light of different frequencies. Due to the low-pass characteristic of the photoelectric converter, the light of different frequencies has different sensitivity through the photoelectric converter. By measuring the sensitivity of the photoelectric converter, Po2 can be determined, and then Spo2 can be determined according to the oxygen ionization curve.
