A ventilator, as a kind of emergency life support equipment, is commonly used in respiratory failure and emergency resuscitation due for various reasons, and it is widely used. The operational status of the ventilator is related to the health and safety of the patient and the ability of the hospital to save the patient. Next, let's take a look at the maintenance and performance testing of the Ventilator.
Here is the content:
l Routine maintenance
l Preventive maintenance
l Performance testing
The routine maintenance of the Ventilator is called primary maintenance, which is carried out by the clinical use department. During the daily use of the Ventilator, the user department must do routine maintenance, including appearance inspection, cleaning and disinfection, and pre-use inspection. The user department is equipped with a record book for each Ventilator, which contains basic information such as surface cleaning, surface disinfection, pre-use inspection, operator, and patient. The user department designates dedicated personnel to clean, disinfect, test and daily calibrate the Ventilator, regularly wipe the ventilator shell with a damp cloth and neutral cleaning solution, clean and disinfect the ventilator pipeline after use, test and calibrate the Ventilator according to the characteristics of the ventilator and the manufacturer's instructions before use, and set and adjust the Ventilator parameters. The Ventilator should be tested and calibrated according to the characteristics of the Ventilator and the manufacturer's instructions before use.
Preventive maintenance (PM) of the Ventilator is secondary maintenance and is performed by a clinical engineer. The clinical engineer should regularly inspect the Ventilator, including whether the ventilator can be turned on normally, and whether the ventilator's audio and visual alarms and ventilation are normal. Regular preventive maintenance of the Ventilator includes but is not limited to, internal cleaning of the ventilator, replacement of consumable parts, performance testing of the ventilator, and repair of Ventilator failures. For example, the flow sensor and pressure sensor of the ventilator should be replaced regularly; the dust filter of the ventilator should be cleaned regularly every month and replaced regularly every year; the air compressor should be overhauled every 5000 hours, and the oxygen battery should be replaced once a year because its life span is generally 1 year. After the failure of the ventilator, clinical engineers should analyze and repair the common failures of the Ventilator according to the working principle and structure of the ventilator, combined with the maintenance manual and fault codes. Through the three-level maintenance program, we can improve the start-up rate of ventilators and ensure the safety of Ventilator use by "prevention-oriented and maintenance combination".
Ventilator performance testing is a three-stage maintenance program, which is performed by clinical engineers or manufacturer engineers. The Ventilator performance test is performed with the aid of a special Ventilator airflow testing device and includes tidal volume, respiratory ratio, ventilation frequency, positive end-expiratory pressure PEEP, time parameters, pressure parameters, and oxygen concentration. Alarm function the main testing items are a power failure alarm, air source alarm, pressure alarm, oxygen concentration alarm, ventilation volume alarm, positive end-expiratory pressure PEEP alarm, and ventilation frequency alarm.
The above is the maintenance and performance testing of the Ventilator. If you are interested in the anti-pandemic Covid-19, Ventilator, you can contact us. Our website is www.medtrue.com.
