How to Size an Emergency Power System or UPS Battery Backup for an Operating Theatre

When sizing the Emergency Power System for critical applications, such as an Operation Theatre, certain factors need to be thoroughly investigated and accurately calculated so the best solution can be provided.

If all the factors are not thoroughly investigated, the Emergency System may end up being an expensive overkill or worse still, unable to perform when called upon in an emergency due to under specifying.

So what are the factors to look into?

In this blog, the Emergency Power experts at Valen look into the critical points that you need to cover to ensure your Emergency Backup System will hold you in good stead in the case of an emergency.

 

New call-to-action

 

Point 1 - Determine the Load

The first point to consider is what equipment needs to be kept running in the operating theatre during a surgical procedure should there be a power failure. If you are a consultant or an electrician, it is best to go over this with the doctor or their accredited consultant. 

Once a complete equipment list has been established, it is a good idea to review this list and highlight the items that are essential to the continuation of the surgical procedures. Generally, these items of equipment are ones that ensure the safety of the patient. 

Factoring in unnecessary equipment can have a significant impact on the calculated size of the Emergency Power system or UPS, unnecessarily pushing up the cost of the Emergency Power system. 

Another point to bear in mind while calculating the load is what items you will require to run simultaneously. For example, an operation table will be used the majority of the time, while other surgical equipment is not required. Therefore, reducing the amount of load on the Emergency Power System during the rest of the time. 

 

Point 2 - Determine run-times per item

Determining run-times per item can have a massive impact on the calculated Emergency Power System or UPS required.

For example, an electro-cautery unit gets momentary usage throughout a surgery. Within a 4-hour long surgery, it might be used only 30 minutes of a 240-minute surgery. 

It is best to calculate a realistic and safe run-time per item for Valen to get an understanding of the size of the Emergency Power System and the battery bank required. 

 

Point 3 - Power Requirements and Conditioning

Another critical factor to check is the voltage your surgical equipment runs at. If there are various voltages, for example, 220VAC loads, additional provisions will need to be made for this in calculations of your Emergency Power System or UPS. 

Bear in mind, that some forms of electronic equipment such as C-Arms and Lasers do not accept modified sine-wave power and can only run on a pure sine-wave form. 

 

In Conclusion...

All these points may seem a bit daunting if you haven't much experience with measuring electrical energy. However, the team at Valen are specialists in critical and Emergency Power Systems and are very familiar with calculating systems like these.
