Frequently Asked Questions

11 of 11
Can AutoTQ be used multiple times, or is it a single-use device?

AutoTQ has a reusable electronics unit that can be cleaned after each use, and a disposable cuff that must be replaced after each use. If you use AutoTQ to save a life, it is our honor to replace your cuff free of charge- just fill out the form at theautotq.com/report.

Does AutoTQ meet the ANSI/ISEA Z308.1-2021 standard for tourniquets?

Yes, AutoTQ exceeds the intent of the ANSI/ISEA Z308.1-2021 workplace first aid standard for tourniquets.

ANSI/ISEA Z308.1-2021 recognizes tourniquets as appropriate supplemental equipment for controlling life-threatening extremity bleeding in workplaces with foreseeable severe injury risks.

While the standard does not mandate a specific tourniquet design, commonly accepted criteria referenced by manufacturers include a minimum width of 1.5 inches and the ability to occlude blood flow across a wide range of adult limb circumferences within a reasonable time frame.

AutoTQ exceeds these expectations with a 3-inch arm cuff, a nearly 4-inch leg cuff, and automated pressure-controlled inflation that achieves arterial occlusion on adult arms and legs in under 60 seconds.

Common misconception: ANSI/ISEA Z308.1-2021 does not require a windlass mechanism. While windlass tourniquets are cited as examples of devices that can meet hemorrhage control needs, the standard does not exclude pneumatic or automated tourniquets that are demonstrably effective.

What if the battery dies?

AutoTQ is equipped with convenient USB-C charging. Upon receiving your AutoTQ, charge the device for at least 3.5 hours until your indicator light is solid green. If you participate in our Wi-Fi Monitoring Program, we will send you monthly battery updates, and notify you when it is time to charge your AutoTQ. If you opt out of the Monitoring Program, we recommend manually checking your AutoTQ monthly to ensure the light is solid green, just like an AED.

How often do I need to charge it?

Once every two years in optimal storage conditions. Check the battery level monthly and store in accordance with product labeling at theautotq.com/labeling.

What is the advantage of using AutoTQ over a windlass tourniquet?

AutoTQ may offer advantages such as ease of use, faster application, and lower risk of user error compared to a windlass tourniquet. Windlass tourniquets have failure rates over 80% for trained users. AutoTQ solves this problem by simplifying tourniquet application to just one button push.

Are there any specific maintenance or replacement requirements for AutoTQ?

AutoTQ automatically conducts daily maintenance checks. AutoTQ must be checked monthly, but can be automatically checked by participating in our Wi-Fi Monitoring Program. This automatically alerts the user when it is time to plug in your battery. Every five years, we will manually replace your battery as part of our maintenance program.

The inflatable cuff must be disposed of after use and replaced, but it is our honor to replace it free of charge if you use it. Just Report a Life Saved at theautotq.com/report.

Can AutoTQ be used on limbs of varying sizes?

AutoTQ designed to be adjustable and adaptable to various limb sizes, allowing for effective use in different situations. Multiple cuffs are available for small and large sized limbs.

How does AutoTQ ensure sufficient pressure to stop bleeding effectively?

AutoTQ is equipped with interactive training and live instructions that walk the user through the process of tightening to stop a bleed. AutoTQ automatically pressurizes to control bleeding. If the pressure is not adequate, the user can easily increase pressure by pressing “inflate” again.

How can I get AutoTQ for my organization?

AutoTQ is now available for pre-order! Visit theautotq.com/shop to order now. Fill out the form at the bottom of the shop page to inquire about special pricing for your organization.

Why should AutoTQ be part of my organization?

Having user-friendly tourniquets accessible is crucial because it can effectively control severe bleeding and potentially save lives.

How do I minimize the risk of using a tourniquet with AutoTQ?

It is important to follow instructions and guidelines to minimize any potential risks or side effects from tourniquet use, and to obtain medical help as quickly as possible after application.
