How to ask Node
Node 2.0 is the point-of-care mode of Cynaps Chat. It gives short bedside answers from the guidelines, drug information and textbooks in the Cynaps library, and every line it writes points to its source. It is open to verified doctors on the web; the Android and iOS apps are coming soon.
What Node is for
- Quick, specific questions at the bedside or in the OPD: a dose, a first-line choice, a threshold, a criterion, the first steps in an emergency.
- Answers are short on purpose: a few lines, each with a source you can open.
- Our library includes Indian national guidance (for example ICMR and MoHFW documents) alongside international guidelines.
Questions that work well
Be specific. Name the drug or condition, and give the patient factors that change the answer.
What a good answer looks like
Each line shows its source pill; open it to read the passage it comes from.
Real examples, shown for illustration. These answers were written by Node 2.0 and trimmed for length. They are not clinical advice and are not a substitute for your own judgement or your hospital's protocol. Answers can change as the library and Node improve. Always open the source and check the dose or decision against it before you act. The questions are examples, not real patients.
Maximum daily dose of metformin in an adult with eGFR 35?
- For eGFR 35, the maximum daily metformin dose is 1,000 mg. KDIGO
- Monitor renal function every 3 months. RSSDI
- Stop metformin if eGFR falls below 30 mL/min/1.73 m². KDIGO
Ondansetron dose for vomiting in pregnancy?
- Ondansetron: 4 mg orally or IV for severe nausea/vomiting in pregnancy; avoid in the first trimester. FOGSI
- Use is generally reserved for refractory cases. FOGSI
- Avoid IV doses >16 mg/day; consider electrolyte and ECG monitoring with arrhythmia risk factors. FOGSI
As per NTEP, daily isoniazid dose for TB preventive treatment in adults?
- NTEP: isoniazid 5 mg/kg/day for adults aged 10 years and older, with a maximum of 300 mg/day. NTEP (MoHFW)
As per ICMR, first-line treatment for uncomplicated P. vivax malaria in adults?
- ICMR: chloroquine 25 mg/kg over 3 days, plus primaquine 0.25 mg/kg daily for 14 days. ICMR
- Primaquine is contraindicated in pregnancy, infants and people with G6PD deficiency. MoHFW (GoI)
Haemoglobin cut-off for anaemia in pregnancy?
- Anaemia is defined as haemoglobin <11 g/dL in the first and third trimesters and <10.5 g/dL in the second trimester. FOGSI
At what CURB-65 score should an adult with pneumonia be admitted?
- Admit at CURB-65 score 2 or more; current NICE guidance allows alternatives to inpatient care at score 2, while recommending inpatient or critical care at 3 or more. WHO
First-line antibiotic for uncomplicated cystitis in a non-pregnant woman?
- Nitrofurantoin 100 mg q12h for 5 days is a first-line choice for uncomplicated cystitis. NCDC (GoI)
- Fosfomycin 3 gm single dose is another first-line option. AIIMS Rishikesh
- Avoid nitrofurantoin if pyelonephritis or systemic infection is suspected. ICMR
Can clarithromycin be given with simvastatin?
- No—clarithromycin and simvastatin are contraindicated together because of increased risk of myopathy, including rhabdomyolysis. FDA
- If clarithromycin is necessary, suspend simvastatin for the duration of clarithromycin treatment. FDA
Questions to avoid, and what to ask instead
Node is not a substitute for your clinical judgement. Check doses and decisions against the cited source.
Reading the sources
- Each line ends with a source pill: the main issuer, and "+N" when more sources support it.
- Tap or hover the pill to see the exact passage Node used, then "Open source ↗" to read it in full.
- If a source looks wrong or does not support the line, tell us with the thumbs-down on the answer or write to support@cynaps.co.
Emergencies
If your question describes a live emergency, Node shows a short safety line first:
This may be an emergency. Start your emergency protocol now — check airway, breathing and circulation, and start CPR if the patient is not breathing normally — and call for help. Outside a hospital, call 108 or 112, continue CPR until the ambulance arrives, and arrange transfer.
It then gives first bedside steps only, each with its source, or says it cannot if the library has nothing usable. Node does not yet recognise every emergency described only by its signs: always follow your own emergency protocol first.
Privacy
- Never type patient identifiers. Before a typed question is sent to an AI provider, Cynaps removes direct identifiers such as phone numbers and ID numbers; this is not perfect.
- What we store and who processes it: see our Privacy Policy.
Questions doctors ask
Why did Node not answer my question?
Node answers one focused question at a time. When a question asks for several things, an explanation or a whole case, Node says so in one line and suggests how to ask instead. If the library has nothing on a topic, it says that too.
Why is the answer so short?
Node is built for the bedside: the key line first, each with its source.
Which sources does Node use?
Indian and international clinical guidelines, drug information and standard textbooks in the Cynaps library. Every line names its source.
