Initial Assessment
Something's wrong
with Marcus
On day 3, Marcus cut his hand on a crampon. Cleaned, dressed, seemed fine. But today he's confused, shivering despite the warmth, and breathing fast. The medic opens FieldMedic and starts the symptom checker — no diagnosis needed to begin. Anyone on the team can drive it.

Patient Record
His records are
already here
Before departure Marcus completed FieldMedic's pre-expedition screening. His full record — blood type, conditions, medications, allergies — is on the medic's phone. Two things are instantly clear: he's diabetic (which explains the rapid deterioration), and there's no penicillin allergy. The right treatment decision is made in seconds, with confidence.

Clinical note: Diabetes increases infection risk and impairs wound healing. Sepsis onset may be faster and presentation atypical. Metformin should be withheld immediately — risk of lactic acidosis in acute systemic illness.

Pre-departure
Kit List
Built before
they left
Before departure the medic entered the trip details and FieldMedic generated a clinically prioritised kit list — ranking every item by medical urgency, flagging exclusions with clear rationale, and keeping everything inside the weight limit. The antibiotics that are keeping Marcus alive were on that list. The IV cannula wasn't — and the handover note will explain why.

Clinical Protocol
One tap to
the full protocol
The medic taps "Open Protocol" from the diagnosis screen. Every management step is numbered and right there — drug doses highlighted, the Metformin warning pulled automatically from Marcus's patient record. The evacuation criteria are clear from the moment the protocol opens: any suspicion of sepsis in a remote setting means evacuate urgently. Treatment begins immediately and evacuation is called — both happen in parallel.

Medical Emergencies
1
Assess using ABCDE. Shout for help — sepsis is time-critical, do not manage alone.
2
CO-AMOXICLAV 625mg oral — broad-spectrum antibiotic. Give immediately as bridging therapy. Do not wait for evacuation — IV antibiotics will be required at hospital.
3
Encourage oral fluids only if ACVPU A and able to swallow safely. Aim 200–300ml per hour — do not give oral fluids with any reduction in consciousness.
4
Monitor temperature, HR, RR, systolic BP, and consciousness (ACVPU) every 15–30 minutes.
5
PARACETAMOL 1g oral — fever and pain control. Avoid NSAIDs in sepsis: risk of renal impairment.
6
Withhold Metformin — patient record shows Metformin 500mg BD. Risk of lactic acidosis during acute systemic illness. Document time of last dose for handover.
7
Keep patient warm and supine if hypotensive. Reassess ACVPU every 30 minutes.
EVACUATION CRITERIA: Any suspicion of sepsis in a remote setting — evacuate urgently. Do not wait for confirmation or improvement. Begin evacuation while treating. IV antibiotics and fluids require hospital-level care.
Evacuation called — 14:31
Helicopter requested the moment sepsis was confirmed. Not after the vitals crashed. Treatment and evacuation run in parallel from here.

Kit Check
Co-amoxiclav
is running low
The medic reaches for co-amoxiclav and the kit shows one course left — already allocated to another patient. FieldMedic instantly suggests doxycycline as the available alternative and opens the pre-administration checklist. Tap the checklist items below — this is exactly how a medic works through it before giving any drug in the field.

Confirm allergy status
No tetracycline or doxycycline allergy documented — safe to administer. Not a penicillin-class drug.

Give with food or milk — patient must remain upright
Reduces gastric irritation and prevents oesophageal ulceration. Patient must remain upright for 30 minutes — do not administer if unable to sit up due to hypotension or reduced consciousness.
Document time and dose given
Record precisely — critical for handover to receiving medical team.
Reassess in 30 minutes
Monitor for response. If consciousness deteriorates further, escalate evacuation immediately.

Vital Signs
Monitoring while
awaiting evacuation
The helicopter was called at 14:31 — 44 minutes ago — the moment sepsis was confirmed on the protocol screen. These vitals don't trigger the evacuation. The evacuation was already happening. What they do is document the deterioration trend for the receiving team and confirm the decision was right the first time.

Septic shock developing
HR 126, RR 26, and temperature 38.9°C meet three of four SIRS criteria confirming sepsis. SBP 84 mmHg and new confusion (ACVPU C) are indicators of septic shock — distinct from SIRS. Oral antibiotic absorption is substantially impaired at this blood pressure. IV fluids and vasopressors are needed — beyond field capability. Evacuate immediately.

Receiving Team Notes
Known T2DM — impaired wound healing, atypical sepsis presentation expected. Metformin withheld 14:40 (last dose estimated 07:00 Day 6); do not restart until haemodynamically stable and oral intake established. Antibiotic cover: doxycycline 100mg BD started 14:35 (first dose given orally — absorption uncertain at SBP 84). Escalate to IV co-amoxiclav or piperacillin-tazobactam on arrival per local protocol. Blood cultures not obtained in field — take on arrival before escalating antibiotics. IV access unavailable in field — oral fluids only. Baseline vitals on file for reference.
