Trishul Peak Expedition AMS Risk Calculator

A mandatory acclimatization day is scheduled at Trishul Base Camp (14750ft). Climatization rotations (load ferry to Camp 1 (Trishul Glacier)) are strictly enforced.

The primary risks on Trishul Peak Expedition are: Crevasse falls on glacier approach, Acute Mountain Sickness (AMS) / HACE / HAPE, Exposed ridge slips, Extreme sub-zero temperatures and high winds. Your operator should brief you on each of these before departure.

Diamox (Acetazolamide) is worth discussing with your doctor if you plan to attempt Trishul Peak Expedition (23,360ft). It is not routinely required for healthy trekkers but is recommended if you have had AMS symptoms on a previous high-altitude trip. Never start Diamox without medical advice — it has side effects including tingling fingers and increased urination.

At 7,120m, a resting SpO2 below 80% is a medical emergency and requires immediate descent. Between 80–85% — monitor closely and do not ascend further. Most acclimatized trekkers maintain 85–92% at this altitude. Carry a pulse oximeter and check readings morning and night.

Strictly prohibited. All high-altitude peaks require IMF permits and certified mountain guide supervision.
