From the use of portable bedside monitors and anesthesia monitors

The portable bedside monitor must monitor the patient's physiological parameters 24 hours a day to reflect the changing trend and indicate the specific conditions for the doctors to treat. Its presence greatly reduces the incidence of complications and achieves the goal of alleviating and eliminating the disease. His custody of physiological parameters include the following aspects: First, the custody of ECG, ECG monitoring equipment is one of the most basic care items, it is through the electrode to obtain ECG signals; Second, the monitoring of the respiratory , Which monitors the patient's respiratory rate by means of a thermal or impedance method; and thirdly, custody of the cardiac output, which in some way injects a quantity of indicator into the bloodstream, after which diffusion Indicator changes in the calculation of cardiac output; Fourth, the guardian of the pulse, which uses photoplethysmography measurement method to reflect changes in the volume of arterial blood vessels, that is, pulse changes. In addition, it also on heart rate, body temperature, blood gas, invasive blood pressure, noninvasive blood pressure and other aspects of custody. It's such a full range of custody, allowing patients to recover faster and better health.

The anesthesia monitor accurately determines whether the patient is in a state of awake, shallow anesthesia, sedation, deep anesthesia and disappearance of electroencephalogram after the patient performs anesthesia, and can also reflect the whole process from awake to deep anesthesia. It has higher controllability. It can clearly indicate the patient's anesthesia depth when the anesthesia operation is not yet started, and can predict the change of the anesthesia state of the patient well and handle it promptly and effectively. It can well solve the problem of deep and shallow general anesthesia, and the numerical fluctuation is small, the data processing is rapid, the testing cost is lower, and can resist the interference of the high-frequency electric knife and the ultrasonic electric knife.
