Inside Everest's Only ER: No X-Ray, 500 Patients a Season, and a Cough That Could Kill You
At 5,364 metres, a canvas tent has been the only emergency room between Everest Base Camp and Kathmandu since 2003 — staffed entirely by volunteer doctors who tell a harmless cough from a killer one with nothing but a stethoscope.

There is no X-ray machine. There is no CT scanner, no on-call surgeon, no ambulance bay. What there is: a canvas tent pitched directly on the Khumbu Glacier at 5,364 metres, a stethoscope, a pulse oximeter, and a small rotating team of volunteer doctors who, for the length of each spring climbing season, run the only emergency room between Everest Base Camp and the nearest hospital — a day's drive and flight away in Kathmandu.
It's called Everest ER, and this month a US physician associate, Jill Nelson, spent two weeks trekking to Base Camp specifically to see it, according to a report published by the American Academy of Physician Associates. What she found is what every visiting clinician finds: a facility that, for all its improvisation, treats hundreds of real emergencies a season with almost none of the equipment a Western ER would consider non-negotiable.
Key facts
- Everest ER was founded in 2003 by Dr. Luanne Freer, run under the Himalayan Rescue Association (HRA), a Nepali non-profit operating since 1973.
- It sits at 5,364 metres — roughly half the oxygen available at sea level.
- The clinic treats 450 to 650 patients every season; in its first nine years it logged more than 2,500 patient visits.
- In the 2018 season, about 60% of patients were Nepali — mostly Sherpa staff and porters, not foreign climbers — and proceeds from paying patients help subsidise their free or low-cost care.
The clinic's hardest daily judgment call, Nelson learned, is a cough. Nearly 40% of everything Everest ER treats is respiratory — upper respiratory infections and "Khumbu cough," the harsh, hacking cough almost everyone develops from breathing cold, bone-dry air at altitude. It's usually harmless. But the same symptom can also be the first sign of high-altitude pulmonary edema (HAPE), a rapid, life-threatening fluid build-up in the lungs and one of the clinic's leading causes of emergency evacuation. Without imaging, telling the two apart comes down to a stethoscope, an oxygen-saturation reading, and a doctor's experience.

What this means for trekkers
What this means for you
Everest ER is a peak-season clinic for climbers and the local Khumbu community, not a facility built for trekkers passing through — but its lessons apply to anyone walking to Base Camp. A cough that develops above 3,500 metres is common and usually nothing. A cough paired with breathlessness at rest, a rattling sound in the chest, or blue-tinged lips is not something to sleep on: it's exactly the HAPE pattern the clinic's doctors are trained to catch early, because by the time it's obvious, descent can no longer wait. Trek with a guide trained in altitude recognition, carry travel insurance that explicitly covers high-altitude helicopter evacuation, and treat any worsening cough above Namche the way Everest ER's doctors do — as the one symptom you don't wait out.
Nelson's trip was run through the Wilderness Medicine Society, which sends US clinicians to Everest ER most years for continuing medical education credit — a small but steady pipeline of foreign doctors who spend two weeks trekking in to volunteer, then work a glacier ER with fewer resources than a rural US ambulance. It's one of the more unusual postings in emergency medicine, and it has been quietly running in a tent above the tree line for more than two decades. Source: AAPA.
