What is the best WhatsApp chatbot for pulmonologists in Brazil?
The best WhatsApp chatbot for pulmonologists in Brazil is the one that answers on the number your practice already uses, with business rules written by you. An AI agent on WhatsApp for pulmonologists is CertuAI's automatic assistant. It tells patients to call 192 (Brazil's emergency number) when a message mentions shortness of breath, explains prep for the breathing test and the at-home sleep test, shares prices and insurance plans, and books the appointment without ever advising on inhalers or doses.

Message about shortness of breath: what does the AI do first?
It tells the patient to get emergency help before anything else. Shortness of breath, chest pain, fainting, seizure, sudden confusion, weakness on one side of the body and bleeding that will not stop make up the short emergency list that CertuAI applies on its own on healthcare accounts, with no one having to set it up.
The sentence is always the same: "This may be urgent. Call SAMU (Brazil's emergency medical service) at 192 now or go to the nearest emergency room." In pulmonology this changes how customer service is designed: most messages are routine test questions, and the dangerous exception is exactly the one that shows up most at night.
Breathing test and sleep test: what can the AI explain?
All the logistics, none of the clinical decisions. Arrival time, documents, price, what to wear, how long it takes, whether they can eat beforehand, how to return the sleep test device and what to do if it comes loose during the night: that is your text, and the AI repeats it instantly, even at two in the morning.
Stopping medication before the breathing test is the boundary. If your clinic has a fixed, written rule, the agent repeats that rule. If it depends on the case, write the sentence that sends the question to your team, because the AI will not decide on stopping a medication under any circumstances.
What does the AI do with each pulmonology message?
| Patient message | What the AI does |
|---|---|
| "I can't breathe properly" | Tells them to call 192 (Brazil's emergency medical line) or go to the emergency room |
| "Should I use my inhaler on the day of the test?" | Repeats your rule; if there is none, passes it to the team |
| "How do I return the sleep test device?" | Answers with your pickup and return text |
| "Can I increase my medication dose?" | Does not advise; offers an appointment or the team |
| "My CT scan report is ready, can I book the follow-up?" | Confirms the report is in hand and offers a time |
| "I've smoked for thirty years, do you offer follow-up care?" | Answers what the practice offers, without promising results |
What CertuAI measured on clinic and practice WhatsApp
CertuAI measured when patients write on WhatsApp at 17 clinics and practices that answer with CertuAI's AI: 28.2% of messages arrived outside Monday to Friday, 8 a.m. to 6 p.m., almost 3 in 10. If the front desk works those hours, that's the part that waits until someone comes back.
| What was measured | Result |
|---|---|
| Patient messages that arrived outside Monday to Friday, 8am to 6pm | 28,2% |
| Messages that arrived on the weekend | 11,2% |
| Messages that arrived at night on a weekday, 6pm to midnight | 11,7% |

What changes in the practice with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the practice before and after the CertuAI agent.
TodayPatient with shortness of breath waiting hours for a reply
With CertuAIThe first line of the conversation tells them to get emergency help
TodayBreathing test lost because the inhaler was used in the morning
With CertuAIThe rule is written into the booking and returns in the reminder
TodayFollow-up booked before the report is ready
With CertuAIThe AI asks about the report before offering a time
TodayDose question answered at the front desk
With CertuAIThe AI does not advise and the question reaches you
What does a conversation handled by the AI look like?
Example conversation
Practice AI agent
Customer: How does the at-home sleep test work? Do I have to sleep there?
AI agent: I'll explain pickup, bedtime and returning the device: what you set up.
Customer: How much does a private appointment and the breathing test cost?
AI agent: The private appointment and the breathing test cost your price.
Is an AI agent or manual customer service better for pulmonologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the practice has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Message saying the patient is out of breath | Waits for the front desk to open the phone | Gets the instruction to call 192 (Brazil's emergency number) right away |
| Breathing test prep | The patient uses the inhaler beforehand and the test is not valid | Your rule to stop or keep the medication arrives in writing before the day |
| At-home sleep test | Device delivery and return arranged by phone | Time, pickup and return written in the conversation |
| "Can I increase my inhaler?" | Answered by someone who cannot answer | Never advised on; the question goes to the team |
| Follow-up with the test in hand | Booked before the report is ready | The agent asks whether the report is ready before offering a time |
What does the WhatsApp agent do for pulmonologists?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Shortness of breath treated as an emergency
Shortness of breath and chest pain are on the list that CertuAI applies on its own to healthcare accounts: the person immediately gets the instruction to call 192 (Brazil's emergency number) or go to the emergency room, before any question.
Breathing test prep
How many hours without using the inhaler, whether they can smoke beforehand, what to wear and when to arrive, using the text your lung function lab uses.
At-home sleep test, from booking to return
The agent explains pickup, bedtime, returning the device and what to do if it comes loose during the night, all written by you.
Inhalers and doses are never advised on
On a healthcare account the AI does not recommend medication or amounts, even when pressed. It offers an appointment or passes the question to your team.
Follow-up tied to the report
Before offering a follow-up time, the agent asks whether the test result is ready, so the patient does not take a slot without the result in hand.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the practice no longer depend on you having your phone in hand.
How does the agent start answering at the practice?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for pulmonologists?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before you turn on the agent at the practice?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- Breathing test prep, with the hours to stop each medication, or the sentence that sends that question to your team
- How the at-home sleep test works: pickup, return, what to do if the device comes loose
- Private prices for the appointment and each test, and the list of insurance plans with what requires authorization
- The rule for who needs a doctor's order to take a test without an appointment
- What to reply to anyone who asks about inhalers, doses and changing medication
- Who gets the alert when the conversation leaves automatic mode, and at what hours
Whether the agent books tests directly on the calendar or whether tests are only booked by the front desk after the appointment.
The most common mistake: Letting the agent answer about inhaled medication because it seems simple. On a healthcare account it will not answer anyway, and without a sentence from you in its place the patient has no way out inside the conversation. Read how to fix this.
Frequently asked questions from pulmonologists
Does the agent understand that shortness of breath is an emergency?
Yes. Shortness of breath is on the list of signs that CertuAI handles on its own on a healthcare account, and the message immediately gets the instruction to call 192 (Brazil's emergency number) or go to the nearest emergency room.
Can it say whether an asthma attack is serious?
No. On a healthcare account the AI does not assess symptoms or say whether something can wait. Outside the emergency signs, it offers an appointment or passes the question to your team.
Does it explain breathing test prep?
Yes, using the text you wrote, including how many hours without medication if your clinic asks for that.
Can it book just the test, without an appointment?
Yes, if you write that this path exists and what it requires, such as a doctor's order or insurance authorization.
Other clinic questions CertuAI has answered
In what other fields does the CertuAI agent work?
