Ventilator self-test program does not include man-machine confrontation.
The ventilator is a vital medical device that can play a role in preventing and treating respiratory failure, reducing complications, and saving and prolonging patients' lives. In modern clinical medicine, it as an effective means to artificially replace the function of autonomous ventilation, has been widely used in various causes of respiratory failure, anesthesia and respiratory management during major surgery, respiratory support therapy and emergency resuscitation, in the field of modern medicine occupies a very important position.
Principles of purchasing a ventilator The ventilator is a useful tool for respiratory support, and is a commonly used treatment for today's critically ill patients. Respiratory support is directly related to the level of rescue of critically ill patients.
Ventilator development and application:
Ventilator micro-computerization degree Ventilator micro-computerization degree determines the grade of the ventilator, manifested in:?
(1) There is a self-test function after power on.?
(2) There are screen prompts in case of malfunction, which is convenient for maintenance.
(3)Perfect alarm function, such as oxygen supply, gas supply, minute ventilation, upper pressure limit, lower pressure limit, respiratory rate, tidal volume, asphyxiation ventilation, background ventilation setting, machine disconnection, air leakage and leakage volume, flow sensor, working status, oxygen flow rate, etc. Many links to ensure that the process of mechanical ventilation is safe, and the clinician can adjust the alarm range of the parameter setting according to the patient's status.?
(4) Other special functions, including sputum suction function, nebulization function, breath-holding function (including inhalation and exhalation breath-holding, to meet the need for chest radiographs), and locking function (to prevent the ventilation parameters from being arbitrarily altered).
