AED in the HOF practice: is it worth having one?

The automated external defibrillator (AED) is one of those devices everyone recognizes from airports and shopping malls, but few orofacial harmonization (HOF) practices have one. The question professionals usually ask is practical: is it worth having one, given that cardiac arrest in an HOF practice is rare?

This page helps you think through that decision, at the level of practice organization. It is not a resuscitation protocol and does not replace in-person basic life support training, which must be given by a qualified instructor and kept up to date with current guidelines.

What is an AED and how does it work?

An AED is a portable device with adhesive pads that stick to the person's chest. It analyzes the heart rhythm and, if it identifies a rhythm that may respond to a shock, guides delivery through voice and light prompts. In general, it will not allow a shock when one is not indicated.

Points that help explain its role:

• it is part of the response to cardiac arrest, together with high-quality chest compressions and the call to SAMU 192 (Brazil's mobile emergency service);
• the benefit depends on speed: the sooner the device reaches the patient, the greater the chance it will be useful;
• it is not meant for someone who is conscious, nor does it work for every arrest rhythm.

For the general context of cardiac arrest in the practice, see cardiac arrest in the practice.

Why does the question come up in HOF?

HOF generally treats healthy people in procedures of low clinical complexity. Even so, a few factors make the question relevant:

1. Patients with underlying conditions that do not always show up in the medical history, or that go unnoticed.
2. Use of anesthetics and sedatives, which carry rare but known risks.
3. Serious reactions, such as anaphylaxis and systemic local anesthetic toxicity (see anaphylaxis in the HOF practice and systemic local anesthetic toxicity).
4. Companions and staff, who can also fall ill in the practice.
5. Distance to help: in places with difficult traffic, SAMU may take a long time.

The rarity of the event does not eliminate the risk. It changes the type of decision: the cost of being prepared is fixed and small, and the cost of not having it, when it happens, is irreparable.

When does it make sense to have an AED?

There is no universal rule, and the decision should consider the context. Weigh:

The conclusion may be "yes," "not for now" or "we have access to a shared AED in the building, and the plan includes going to get it." What matters is that the decision is conscious, documented and consistent with the rest of the emergency plan.

Does the device alone solve it?

No. An AED without training and maintenance gives false comfort. What actually saves lives is the whole package:

Also confirm the equipment's regulatory status with the health authority and follow the manufacturer's instructions. See how to check an injectable's ANVISA registration for the verification logic, which applies similarly to other health products.

Who should be trained?

Everyone on the team present during appointments, including reception and support staff, should know the essentials: recognize arrest, call SAMU, start high-quality compressions and fetch the AED. Formal training is given by a qualified instructor and should be refreshed according to current guidelines. See reception training in HOF and team emergency drill.

And what about integration with the emergency plan?

The AED is one piece of the plan. No device replaces prevention, which starts with the HOF medical history, recognizing risk and declining or postponing when the picture is not safe. Nor does it replace the HOF practice emergency kit, which covers other frequent scenarios, or knowing when to call SAMU.

For documentation, record the decision about the AED (whether you have one, why, with what routine) in the clinic's safety manual. If it is ever actually used, document everything in the patient record and the incident report (see emergency documentation in the practice).

Cost and maintenance: what to weigh?

Without citing figures, the cost of an AED involves purchasing or leasing the device, replacement pads and battery, team training and periodic maintenance. Compare buying with a lease that includes maintenance, and ask the supplier about technical support, response time and replacement of consumables. Also consider the possibility that the building already has one, and include the route to it in the plan.
