Product Overview

This **hyperbaric chamber**, manufactured by MROZY, is specifically engineered for reliability and is **suitable for repeated use on demanding expeditions**. It's your vital tool for simulating altitude descent during acute mountain sickness.

Key Technical Specifications

• Dimensions: Generous space at 225 cm (L) × 75 cm (W) × 55 cm (H).
• Weight: Remarkably light at only **1000 g** (chamber only) for easy transport.
• Internal Volume: Ample air supply with approx. **600 L** of internal volume.
• Fabric: Constructed from high-tenacity nylon coated with durable **Thermoplastic Polyurethane (TPU)**.
• Closure System: Secured with a heavy-duty, **airtight zipper** to maintain pressure integrity.
• Attachment Loops: 10 mm wide non-fraying polyamide webbing straps for secure placement.
• Window: Equipped with a clear **TPU film window** allowing for visibility and communication.

Usage & Performance Metrics

The Alti Equipment chamber is designed for rapid deployment and effective pressure treatment, providing the equivalent of a quick descent.

• **Pump Compatibility:** Fully compatible with standard air pumps (recommended: **Flextail Max 3** or a reliable standard foot pump).
• **Tested Pressure:** Tested up to **15 kPa**, simulating a significant ~2000m altitude descent.
• **Recommended Operational Pressure:** Maintain at **10 kPa**, which effectively simulates a **1500m descent**.
• **Inflation Times:**
  • Electric inflation to 5 kPa (~750m descent simulation): takes only **~1:30 mins**.
  • Manual inflation from 5 kPa → 10 kPa (to reach max recommended pressure): takes approx. **~2:00 mins**.
  • *Note: Manual pumping is required to exceed 5 kPa.*
• **Air Management:** The chamber is both internally and zipper purgeable for air refreshing.
• **Air Refresh Cycle:** Essential for oxygen management: release the zipper slightly for **~1:30 mins every 30 minutes maximum**.
• **User Convenience:** The clear window allows for easy monitoring and permits **touchscreen use** of devices inside.
• **Securing:** Features a clip attachment point (for securing the chamber only, **not for suspension or lifting**).

Step-by-Step Instructions

1. **Preparation:** Find a **flat, safe area** free from sharp objects and fully unroll the chamber.
2. **Padding:** Place padding underneath if available (e.g., a sleeping mat) for insulation and comfort.
3. **Setup:** Lay the chamber on top of the padding and attach your pump to the valve.
4. **Security:** Secure the chamber using the loops to prevent it from sliding or falling during use.
5. **Essentials:** Place recommended items inside: pee bottle, phone, altimeter watch, water, warm clothing, and emergency tools.
6. **Inflation:** Place the person and all items inside, zip up the airtight closure, and begin steady pumping.
7. **Monitoring:** Use a measuring device (altimeter or pressure gauge) to continuously monitor the pressure inside.
8. **Maintenance:** Maintain a maximum pressure of **10 kPa**. Continuous pumping is allowed for **30 minutes maximum** before an air purge is required.
9. **Purging/Air Refresh:** To refresh oxygen levels, slightly open the zipper for approximately **~1:30 minutes**, then immediately reseal it.
10. **Deflation:** To end use, slowly reduce pressure by using the relief valve or gradually opening the zipper.
11. **Safety:** **Ensure clear communication and monitor the person inside at all times.**
12. **Post-Use Care:** After use, remove all contents, turn the bag inside out, and hang it to thoroughly dry.
