The CMO holds the probe, as in RMP-GI-001: "Contact with the crewmember: not allowed". result_language: use: - non-diagnostic - images acquired, for human review - image not obtained - reading as displayed - sent to flight surgeon - as stated by the crewmember never: - normal - no problem found - all clear - negative - any diagnosis or cause - looks fine - nothing seen - verified - no abnormality - clear - pneumothorax - no pneumothorax - collapsed lung - lung sliding - B-lines - fluid - no fluid - pneumonia - lungs clear - safe - mild - minor - lung point - A-lines - consolidation - effusion - no B-lines - sliding present - sliding absent - good images - adequate scope: summary: >- When the flight surgeon or CMO wants a lung ultrasound (for example for shortness of breath, chest pain after an injury, or a low oxygen reading), the robot alerts the flight surgeon at once, brings the ultrasound kit by a checked kit fetch, holds the display and the probe reference card where the CMO can see them, relays live images and voice to the ground imaging expert when the link allows, and labels and stores each clip with the chest zone the CMO names and the clock time. The CMO holds the probe. Every image is "non-diagnostic, for human review": the robot never reads an image or says what it shows. why: >- Point-of-care lung ultrasound is used in emergency and critical care on Earth, with 73 international consensus statements covering, for example, a collapsed lung (pneumothorax), fluid around the lung and lung consolidation (Volpicelli 2012). In an animal model on parabolic flights, ultrasound detected small amounts of air and fluid in the chest (Hamilton 2004), and on the ISS a minimally trained crewmember, guided from Mission Control, completed a remote-guided ultrasound examination (Sargsyan 2005). NASA's in-flight medical conditions evidence report describes the ADUM (Advanced Diagnostic Ultrasound in Microgravity) project, which guides "minimally trained crewmembers" by remote guidance and just-in-time instruction. Here ultrasound is diagnostic only: it never delays oxygen, the call to the flight surgeon or emergency care, and an onboard CMO is not an experienced operator, so images are for remote expert review only and never rule anything out. Which chest zones are scanned is set by the onboard checklist or the ground expert (design judgment). The shared value SPO2_ALERT_PCT only raises an alert; it never gates a crew action (the crew act without waiting for a reading), and the clinical lead sets it per mission with the flight surgeon, because the cabin atmosphere can differ by mission. covers: - >- Lung ultrasound with a crew-held probe, in flight or on a planetary surface, with ground remote guidance or store-and-forward - 'Shortness of breath and oxygen: RMP-RESP-001; chest pain: RMP-CARD-002; injury: RMP-MSK-001' - Probe cleaning under RMP-INF-002 locked_out: - Diagnosis or naming a cause - Any medicine, fluid or oxygen advice; starting, stopping or adjusting oxygen - Touching the crewmember - >- Handing over any medicine outside RMP-PHARM-001, or after a MISMATCH or CANNOT VERIFY (the item stays quarantined; only the CMO can ask for it, through the RMP-PHARM-001 logged two-step override) - Holding, moving or pressing the probe, or touching the chest - Reading or measuring an image, or saying what an image shows or does not show - Starting, stopping or adjusting oxygen - Any procedure on the chest (for example needle or tube placement) - >- Scanning over an open wound or broken skin, unless the flight surgeon directs it with a sterile cover related: - RMP-RESP-001 - RMP-CARD-002 - RMP-MSK-001 - RMP-GI-001 - RMP-INF-002 - RMP-CARD-001 - RMP-PHARM-001 roles: medical_authority: Flight surgeon (ground).

If no trained responder is aboard, this protocol is not used. (NASA-STD-3001 requires two CMOs per vehicle for NASA programs [V1 3006]; FAA rules set no medical standards for spaceflight participants.) preconditions: - id: PRE-1 text: The CMO or the flight surgeon asked for a lung ultrasound by command. check: human_start == true refs: - V2 10174 - id: PRE-2 text: Robot self-test passed; kit stowage locations known. refs: - V2 10161 - V2 7059 - id: PRE-3 text: Robot and supplies restrained when not moving. refs: - V2 7046 - id: PRE-4 text: Link status known.

Images go only to the flight surgeon and the ground imaging expert the flight surgeon names. emergency: If the crewmember cannot agree, the robot proceeds on the CMO's command; the scan never delays care. withdrawal: The crewmember can stop the scan, images or video at any time; the alert and the record stand. inputs: - id: IN-1 name: The reason for the scan and the chest zones to scan, as the CMO or ground expert names them source: CMO / ground imaging expert required: true if_missing: The robot shows the onboard scan checklist; the CMO decides. - id: IN-2 name: Breathing symptoms in the crewmember's words source: Crewmember required: false if_missing: Log "no response"; D3 applies. - id: IN-3 name: Oxygen saturation and heart rate as displayed source: Crew-placed pulse oximeter required: false if_missing: Log "saturation not obtained" (never a value); see RF4. - id: IN-4 name: Ultrasound clips, each with the zone the CMO names source: Ultrasound unit required: false if_missing: Log "image not obtained" (never a reassuring value) and continue. - id: IN-5 name: Link status and delay source: Communications system required: true if_missing: Treat as link down; store and forward. steps: - id: S1 actor: robot rung: 2 action: >- Send a "lung ultrasound requested" notice to the flight surgeon and the CMO at once (URGENT if a red flag is already stated). Every URGENT alert goes to the CMO and the flight surgeon at the same time (queued for the flight surgeon if the link is down). If the CMO is the patient, is busy treating, or does not answer, the alert goes to the second trained CMO, or the crewmember named before flight [V1 3006]. An URGENT alert that is not acknowledged within seconds is repeated and sent to the next named crewmember. success: Notice acknowledged, or escalated. refs: - V2 10174 - V1 6003 - V1 3006 - id: S2 actor: robot rung: 2 action: >- On the CMO's command, run a checked kit fetch of the ultrasound medical kit (unit, sealed gel and probe-cover pack): check the kit ID and seal before hand-over, and quarantine a kit whose ID or seal does not match (no hand-over; the CMO is told). Any medicine goes only through RMP-PHARM-001. If an URGENT red flag has fired or a human states an emergency, bring it instead as an emergency fetch: This is an emergency fetch on a human command (CMO): no barcode check runs before hand-over and nothing waits for one. The robot reads the kit's own label and seal status only if that adds no delay, says "EMERGENCY FETCH – NOT VERIFIED (CMO command)", and "seal not intact" if so, and hands the kit over anyway. The fetch is logged as an override: time, who asked, the reason as stated, kit ID and seal status. It never says "verified". success: Kit within reach after a matched ID and seal, or quarantined, or emergency fetch logged. limit: refs: - V2 7046 - V2 7059 - id: S3 actor: crew action: >- The CMO checks breathing and oxygen first under the onboard checklist (RMP-RESP-001); the crewmember and the CMO are restrained for scanning.

The probe and gel are never placed on an open wound or broken skin unless the flight surgeon directs it with a sterile cover. success: Scan done, stopped, or not possible. refs: - V1 3004 - id: S6 actor: robot rung: 2 action: >- Label and store each clip with the zone the CMO names and the clock time, mark every clip "non-diagnostic, for human review", record oxygen saturation as displayed, and log stated answers word for word. A device image-quality prompt is passed on to the CMO as displayed; the robot never judges an image. success: Clips labelled; gaps logged as "image not obtained". refs: - V1 7001 - id: S7 actor: crew action: >- After the scan, the crew clean the probe and any shared surface under RMP-INF-002; a probe on intact skin is noncritical equipment, and a probe cover never allows a lower level of cleaning. A probe that touched broken skin is semicritical equipment: the crew tag it "not for use" under RMP-INF-002 until it has had high-level disinfection. success: Cleaning recorded as stated under RMP-INF-002. refs: - V2 7046 - id: S8 actor: robot rung: 2 action: >- After any URGENT alert: After an URGENT alert the robot does not leave on its own: it stays at its rest position in the module, with its screen and voice link available, until a human has taken over or tells it to go. It never follows, blocks or touches anyone. It keeps time-stamping what humans say they did, and repeats the alert if it is not acknowledged. success: Robot at rest in the module until a human releases it; alert acknowledged or escalated. refs: - V2 10173 - V1 3006 - id: S9 actor: ground action: >- The flight surgeon with the ground imaging expert (or the CMO under the onboard checklist when there is no link) reviews the images and decides on care, repeat scans and any evacuation [V1 3007]; evacuation preparation follows RMP-EGR-001. success: Decision logged. refs: - V1 3007 - id: S10 actor: robot rung: 2 action: >- Only after the CMO or flight surgeon has placed an order, run RMP-PHARM-001 for the ordered item (fetch, barcode match to every order field, recipient check). This protocol adds nothing to that check, never suggests an order, and never hands anything over outside RMP-PHARM-001. success: RMP-PHARM-001 run logged with its result, or none ordered. refs: - V2 7059 - id: S11 actor: robot rung: 2 action: >- When the CMO says the event is over, run RMP-PHARM-001 reconciliation on each kit fetched: record the items the CMO or crew state were used, the remaining contents against the kit list, seal status and expiry, labelled "inventory reconciliation after emergency use – not a check before use". Flag the override to the flight surgeon and the pharmacy lead, and show each kit as "opened – not restocked" until a human restocks and reseals it. success: Reconciliation recorded; kit shown as opened – not restocked until resealed. refs: - V2 7059 - id: S12 actor: robot rung: 2 action: >- Send the flight surgeon one package: stated answers, saturation as displayed, labelled clips, times and decisions; images go only to the people the flight surgeon names. success: Package delivered or queued. refs: - V1 6003 - V1 7001 - V1 7003 decisions: - id: D1 after: S2 decided_by: robot question: Which kit fetch was it, and what did the checked kit fetch show? branches: - if: EMERGENCY FETCH (an URGENT red flag had fired, or a crewmember or the CMO stated an emergency) then: >- Hand-over already done as an emergency fetch, logged as an override; reconciled afterwards (not a check before use). - if: KIT ID AND SEAL MATCH then: >- Hand the kit over closed; log "KIT ID AND SEAL MATCH. Not a check of the contents." and the clock time. - if: MISMATCH, seal not intact or CANNOT VERIFY then: >- Shown with the reason. No hand-over under this protocol: the kit stays sealed in quarantine (the RMP-PHARM-001 default), and the robot never hands it over unprompted or to anyone but the CMO. The robot does not offer or suggest an override. Only if the CMO explicitly makes the two-step override request inside RMP-PHARM-001 can the kit go to the CMO, logged there as an override with the reason, and flagged to the flight surgeon. If the need becomes an emergency, a crewmember or the CMO states it and the emergency fetch applies. handoff: none - id: D2 after: S6 decided_by: robot question: >- Checked after every answer and at any point in the run (even mid-question or mid-step): does any answer, reading or observation meet a red flag? branches: - if: 'Yes' then: >- Stop the current question or step at once and apply the action listed for each matching red flag (URGENT alert, flag, or stop), with the answer or reading itself, never a cause. Every URGENT alert goes to the CMO and the flight surgeon at the same time (queued for the flight surgeon if the link is down). If the CMO is the patient, is busy treating, or does not answer, the alert goes to the second trained CMO, or the crewmember named before flight [V1 3006]. An URGENT alert that is not acknowledged within seconds is repeated and sent to the next named crewmember. - if: 'No' then: Continue. - id: D3 after: S6 decided_by: robot question: Did the crewmember answer the last question? branches: - if: 'Yes' then: Continue. - if: Declined explicitly (the crewmember says no to a question) then: Log "declined" for that question only; the alert already sent stands. - if: No response, or the answer does not make sense then: >- URGENT: log "no response" (never "declined"); the CMO, or the second trained CMO if the CMO is the patient, checks the crewmember in person at once. - id: D4 after: S9 decided_by: ground question: What is the plan (care, repeat scan, evacuation)? branches: - if: Link live then: Flight surgeon decides; robot logs. - if: Link down or delay too long then: >- The CMO decides under the pre-approved onboard checklist; the flight surgeon reviews the log at the next contact. - id: D5 after: S10 decided_by: robot question: What did RMP-PHARM-001 show for the ordered item? branches: - if: MATCH TO ORDER then: >- RMP-PHARM-001 completes its own recipient check and hand-over; this protocol only logs "MATCH TO ORDER. Not a dose, interaction or allergy review." and the clock time. - if: MISMATCH or CANNOT VERIFY on any field, or a failed scan or recipient check then: >- MISMATCH or CANNOT VERIFY shown with the fields named. No hand-over under this protocol: the item stays sealed in the NOT VERIFIED bag in quarantine (the RMP-PHARM-001 default), and the robot never hands it over unprompted or to anyone but the CMO. The robot does not offer or suggest an override. Only if the CMO explicitly makes the two-step override request inside RMP-PHARM-001 can the item go to the CMO, logged there as an override with the reason and the mismatched fields, and flagged to the flight surgeon. handoff: none stop_rules: - id: X1 trigger: The patient (or the crewmember being examined) says stop, or withdraws consent action: >- Robot stops all motion at once, backs away to its rest position and tells the CMO.

This pauses robot movement only: crew oxygen, breathing care and all crew care continue under the onboard checklist and never wait for the link or the robot. The CMO decides whether the robot continues offline under the pre-approved onboard checklist; it resumes only on the CMO's confirmation. level: pause refs: - V2 10172 - V2 10173 - id: X6 trigger: An URGENT alert is not acknowledged within the set time action: >- Robot repeats the alert and sends it to the next named crewmember (the second trained CMO first if the CMO is the patient), and keeps repeating at the set interval.
