Discussion on the difference between portable bedside monitor and anesthesia monitor

A monitor is a system or device that controls and measures the patient's physiological parameters and can be compared to known settings if an alarm occurs. It can be on the patient's blood pressure, ECG, body temperature and other parameters of continuous monitoring, health care workers can be comprehensive and timely provision of the patient's condition for medical staff for treatment or emergency treatment. With the advancement of society and the continuous improvement of medical equipment, the monitor will be more quickly spread to become the ward's most common medical equipment. There are many types of monitors, of which the more common are portable bedside monitor and anesthesia monitor, etc., then we take these two monitors, for example, the specific analysis, to discuss their use, the scope of use the difference.

1 conceptually distinguishes portable bedside monitors and anesthesia monitors

The portable bedside monitor is a monitor attached to the bed and connected to the patient. It can detect various physiological parameters such as blood pressure, ECG, body temperature, respiratory and cardiac function. It can be divided into single parameter bedside monitor and multi-parameter bedside monitor. Single-parameter bedside monitor can perform real-time, continuous monitoring of patients and display them. If the patient's heart rate, ECG and other aspects of abnormal, will automatically issue an alarm, which is characterized by the application of micro-computer data processing, and based on the establishment of the mathematical model to make a diagnosis; multi-parameter bedside monitor is basically the use of Plug-in structure, its configuration is relatively independent and very flexible, by changing the settings, either as a bedside monitor, but also as a central monitor. Anesthesia monitor is an instrument for inhalation general anesthesia, which uses semiconductor gas sensor, through the chemical dialysis membrane for gas selection, can quickly and easily detect different anesthetic gas. It is characterized in that the semiconductor gas sensor is welded by a semiconductor gas sensor on a ceramic chip, the ceramic sheet is in close cooperation with the metal cylinder and is sealed with silicone rubber. The other end of the metal cylinder is separated by two layers of chemical dialysis film A layer of glass sand core composition. It is an important tool that must be used for anesthesia, which can provide oxygen to the patient, inhalation of anesthetics, and for breathing management. It has four basic functions: one, must be able to provide the power to transport gas, instead of the work of the human body ventilator; Second, he must meet the needs of respiratory metabolism, to provide the amount of tidal volume or ventilation; The supply of gas to be heated and humidified, instead of nasal function, but also to supply higher than the oxygen in the air; Fourth, he was able to produce a certain breathing rhythm, in place of the body respiratory center of the respiratory rhythm of the function. It mainly consists of gas supply and transportation system, anesthesia gas evaporation tank, respiratory circuit system, ventilator, safety monitoring system and residual gas removal system, anesthesia information system and so on, its existence greatly improved the efficiency of medical institutions.

2 distinctions from the use of portable bedside monitors and anesthesia monitors

Portable bedside monitor must be 24 hours of uninterrupted monitoring of the patient's physiological parameters, reaction trends, indicating the specific circumstances for the treatment of doctors, its existence greatly reduces the incidence of complications, to alleviate and eliminate the purpose of the disease. His monitoring of physiological parameters mainly include the following aspects: First, the ECG monitoring, ECG monitoring equipment is one of the most basic monitoring project, it is through the electrode to obtain ECG signal; Second, the monitoring of breathing , It is through the thermal or impedance method to monitor the patient's respiratory rate; Third, the cardiac output monitoring, it is in some way, a certain amount of indicator injection into the blood, in which the proliferation, The change of the indicator to calculate the cardiac output; Fourth, the pulse of the guard, it uses the photoelectric volume pulse measurement method, reflecting the arterial volume changes, that is, pulse changes. In addition, it also on the heart rate, body temperature, blood gas, invasive blood pressure, noninvasive blood pressure and other aspects of monitoring. It's this all-round care, can make the patient faster and better to restore health.

Anesthesia monitor can be in the patient after anesthesia, the exact judge whether the patient is in a sober, shallow anesthesia, sedation, deep anesthesia and disappearance of EEG status, but also reflect the patient from the sober to the depth of the whole process of anesthesia. It has a high controllability, in the anesthesia surgery has not yet begun, it can be very clear that the patient's anesthesia depth, but also a good prediction of changes in patients with anesthesia, and timely and effective treatment. It can be a good solution to the problem of deep and shallow general anesthesia, and the value of small fluctuations, rapid data processing, testing costs are low, able to resist high-frequency electric knife, ultrasonic interference.
