Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G4; Focused research depth Automated method-quality band: Comprehensive Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context This lesson teaches the supervised altitude-acquisition method: define the itinerary, obtain travel-health review, plan staged ascent and sleep altitude, learn acute mountain sickness and emergency signs, track symptoms rather than fitness alone, preserve descent and communication routes, and reassess every upward move. It gives no medication or hypoxia-simulation advice. Target outcome: The learner and qualified travel-health provider produce a day-by-day altitude plan with sleep elevations, ascent decisions, symptom checks, descent triggers and emergency contacts. ### Authority and setup conditions - Tell the provider the route, previous altitude response, health conditions, pregnancy, medicines, recent illness and remoteness. - Mark where slower ascent, rest, descent, transport and medical help are realistically available. - Agree the symptoms that prevent ascent and those that require immediate descent and emergency care. ### Required or supplied materials - A map or itinerary with starting, daily maximum and sleeping altitudes. - Current official travel-health guidance and the traveller’s provider-approved plan. - Daily symptom sheet, companion check, communication/descent map and emergency contacts. ## 1. Map the ascent profile List altitude reached and sleeping altitude for every day, plus transport and effort. Why: Risk relates strongly to ascent and sleeping profile, not only the destination. Success check: No day has an unknown sleep altitude or hidden rapid gain. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No day has an unknown sleep altitude or hidden rapid gain.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Complete travel-health review Review personal risk, previous illness, route and contingency with a qualified provider; record advice without sharing private details unnecessarily. Why: Individual advice can change the itinerary or no-go decision. Success check: The plan is cleared, modified or declined by the appropriate provider. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The plan is cleared, modified or declined by the appropriate provider.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Learn symptom groups Distinguish common altitude headache with associated symptoms from severe confusion, inability to walk straight, breathlessness at rest or chest signs. Why: Correct recognition drives the next action. Success check: The learner and companion can match each symptom card to hold, descend or emergency. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner and companion can match each symptom card to hold, descend or emergency.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Preserve descent and help Name the lower location, transport, communications, companion roles and what happens if weather or night blocks the preferred route. Why: “Descend” is not a plan unless it can be executed. Success check: A realistic primary and alternate help route are recorded. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “A realistic primary and alternate help route are recorded.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Establish a low-altitude baseline Before ascent, record normal sleep, headache, nausea, dizziness, fatigue, coordination and any provider-selected measures. Why: Symptoms and devices have personal baselines and measurement limits. Success check: The baseline is dated and does not create a health score. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The baseline is dated and does not create a health score.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Follow the planned stage Use the provider-agreed ascent and rest pattern; do not add rapid gains or strenuous efforts to make up time. Why: Schedule pressure is a common reason plans drift. Success check: Actual sleep altitude and exertion match the plan or upward progress stops. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Actual sleep altitude and exertion match the plan or upward progress stops.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Run the symptom decision check At each planned point, the traveller and companion separately check symptoms, walking/coordination and function, then reconcile differences. Why: Illness can distort effort ratings and make altitude symptoms harder to interpret. Success check: The decision is ascend, stay/no higher, descend or emergency—not “push and see.” Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The decision is ascend, stay/no higher, descend or emergency—not “push and see.”” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Use devices as context only If the provider included pulse oximetry, record device, conditions and trend but let symptoms and clinical guidance control. Why: A single number can be inaccurate or falsely reassuring. Success check: No upward decision rests on one reading. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No upward decision rests on one reading.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 9. Reassess before every higher sleep Check that symptoms are absent or improving under the plan, descent remains possible and the next stage is still authorised. Why: Acclimatisation is an ongoing decision, not a one-time clearance. Success check: Every ascent has a signed or shared go/no-go entry. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Every ascent has a signed or shared go/no-go entry.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 10. Review return and future routes Record any symptoms, actions and recovery; treat a future route or long break as a new plan. Why: Prior success does not guarantee another trip. Success check: The next itinerary begins with new review rather than inherited confidence. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The next itinerary begins with new review rather than inherited confidence.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt.
