Improve the efficiency of rescue breathing machine intelligence testing implementation strategy (1)

1. the importance of Intelligent detection

Ventilator in the major hospital clinical first aid is one of the most critical devices, in a modern hospital equipment in occupies an important position.

But because of respiratory equipment, jishu rescue has its own special factors, is often the easiest to clinical problems, use one of the difficult equipment, respiratory machine maintenance becomes especially important. In the absence of the appropriate detection device, giving full play to the ventilator's own intelligence test (post) becomes especially important to first determine whether the ventilator is in a normal working condition, the timely detection of problems, to ensure that the ventilator is always in the best performance.

2. Intelligent detection of difference

My home is now common respiratory machine series has the following four types: Puritan United States — Bennett (PB), New York State (New Port), Germany Siemens (SIEMENS), Draeger (Drager).

That several models of different degrees of intelligence, setting up, testing, measurement allows error size is different, thus in Intelligent detection (post) performance testing will also vary. There are very simple, as long as observation Panel indicators are lit when powered on, a few minutes without any human action that can be adopted (such as New York State, Draeger, etc.), but some are more complex, more complex, more time-consuming, need to go through a certain operation to complete (such as PB, Siemens, etc.).

3. Intelligent detection steps

Different types and grades of ventilator its self-test procedure all different, more easy, some are more complex and time-consuming to PB840 ventilator's post as an example on its operational processes and considerations.

PB840 ventilator for post primary are 3: POST (Power On Self Test) — post, SST (Short Self Test) — quick post, EST (Extended Self Test) — complete post.

3.1 POST (Power On Self Test) — a post:

Mainly used for ventilator circuit hardware integrity and non-operational due to system failure, when the power on or restart the machine will run automatically, normally POST available 7.25 seconds.

3.2 SST (Short Self Test) — quick post:

Mainly used for testing patients pipe leaks, pipe and measurement calibration patients breathe out side the resistance of bacterial filter.

In patients with ventilator-connection, use before 15 days later, replacement patients after maintenance machines pipes, as well as replace the wet cell, water glass and so affect airway resistance and compliance of attachment and the implementation of the SST.

The implementation of the SST: ① connect the power supply and air source and breathing circuits, open the ventilator power, then the screen select the menu appears, touch quick self-test SST, select, and then 5 seconds down on the left of the ventilator host TEST key, then enter the ventilators of rapid testing mode.

② into self-test mode, the screen will appear a SST's settings menu, and select the good ventilator circuit and humidifier type. ③ Choosing good ventilator circuit and humidifier type after press the Accept (enter) to confirm, respiratory machine will automatically start self-test procedure:

Flow Sensor 1) SST Test flow sensor test: first screen prompts respiratory pipe without humidification device directly received on suction side filter (filter circuit Connect with and without humidifier insp), confirmed after execution, the screen will prompt you to block Y estuary (Block wye), after the implementation of the instruments will be recognized for flow sensor detection, detection of bi on-screen: If you use a humidifier, please connect the humidifier (Connect humidifier if applicable), to perform that breathe the opportunity to automatically move to the next step;

2) Circuit Pressure Test pipe stress testing;

3) Circuit Leak pipeline leak tests;

4) Expiratory Filter Test outbound side filter test: screen prompts you to even in the outbound side filter pipeline disengage (Disconnect PATIENT at FROM port), after confirming that the executed tests pass automatically to the next step in the action;

5) Circuit Resistance pipe resistance test: the first screen will prompt release Y estuary (Block wye), after confirmation, respiratory performed automatically move to the next step;

6) Compliance calibration compliance test: screen prompts release Y, after confirmation, the instrument will be detected, and then the screen prompts to block the execution of Y, confirmed that the instruments for testing.

Detect all SST detection after project completion. Finally select EXIT to exit the quick post SST.

3.3 EST (Extended Self Test) — complete with:

Mainly used to check the respirator all gas and some circuits (including gas mechanics, compressors, sensors, power supplies, parts, and so on), EST contains POST and SST some steps.

When breathing machine running 6 months later, when the repair, replacement or maintenance of the machine to run EST, EST can effectively help us find the faulty part.

The implementation steps: EST ① machines most pioneers preheating for 10 minutes.

② Connect power, and even the good air and oxygen gas (air compressor can be used as air), remove the suction side filterThe gold standard test circuit (gold line) direct connection of the suction side ventilators and exhale side. ③ the power switch on the machine, when you see the aspirated unit lamp, in 1 seconds press the ventilator to the left of the Test key, the machine enters the system of maintenance mode. ④ enters the system maintenance mode after touching moment EST key and press the Accept (enter) to confirm that the ventilator is automatically entered EST process:
