Types and use of portable hyperbaric chambers Gamow bags
Jet stream influence
Portable hyperbaric chambers, commonly referred to as Gamow bags, are a crucial component of high-altitude medicine and rescue. Named after Dr. Igor Gamow, these innovative devices have revolutionized the way mountaineers and adventurers combat the dangers associated with acute mountain sickness (AMS), high altitude cerebral edema (HACE), and high altitude pulmonary edema (HAPE).
Essentially, a Gamow bag is an inflatable pressure vessel designed to simulate descent by increasing the atmospheric pressure around an individual. When someone suffers from altitude sickness due to rapid ascent without proper acclimatization, their body experiences significant stress because of reduced oxygen levels in the air. The symptoms can range from mild discomfort to life-threatening conditions.
The primary use of a Gamow bag is in emergency situations at high altitudes where immediate descent is not possible or practical.
Physiological effects
For example, if a climber develops severe AMS and cannot physically descend due to exhaustion or terrain constraints, they can be placed inside this portable chamber. Once zipped inside, the bag is inflated with a foot pump—increasing the internal pressure effectively simulates being at a lower altitude.
By mimicking conditions found at lower elevations, the Gamow bag allows for more oxygen to be available to tissues that are starved under hypoxic conditions prevalent at higher altitudes.
Altitude training
This provides temporary relief from symptoms of AMS and can be lifesaving by buying time until a safer descent can be undertaken or further medical treatment can be provided.
Jet stream influence
It's important to note that while using a Gamow bag requires some training—it's relatively straightforward. The process involves placing the patient in the bag up to their neck and sealing it before inflating it with air until reaching the desired pressure level indicated on a built-in gauge.
In addition to emergency uses on mountain expeditions, these portable chambers also find usefulness in remote locations where access to medical facilities is limited or nonexistent. They provide an essential intermediate solution for treating serious altitude-related illnesses until definitive care can be accessed.
However, despite their benefits in emergency scenarios, reliance on Gamow bags does not replace proper acclimatization strategies which remain paramount for safe high-altitude travel. Moreover, they should not encourage individuals who are unwell or unfit for high-altitude environments simply because they believe there’s an easy fix available.
In conclusion, while no one hopes to encounter circumstances warranting its use, having access to a portable hyperbaric chamber like the Gamow bag offers peace of mind when venturing into thin-air territories above sea level.

Frequently Asked Questions
What is a portable hyperbaric chamber, also known as a Gamow bag, and how does it work in the context of mountain climbing?
A portable hyperbaric chamber or Gamow bag is an inflatable pressure vessel designed to simulate a descent to lower altitude for individuals suffering from altitude sickness. It works by increasing the air pressure around the patient, which increases the oxygen saturation in their blood, helping alleviate symptoms associated with low atmospheric pressure at high altitudes.
When should a Gamow bag be used during a mountain climbing expedition?
A Gamow bag should be used when a climber exhibits severe symptoms of altitude sickness that do not improve with standard treatments such as rest, hydration, and descending to a lower altitude. Symptoms can include disorientation, loss of coordination (ataxia), severe headache, vomiting, fatigue, and shortness of breath.
How is the Gamow bag set up and operated properly on a mountainside?
To set up the Gamow bag, you spread out the chamber flat on the ground away from sharp objects. Then place the person inside and seal it shut. Inflate it using either a foot pump or hand pump until it reaches the recommended pressure indicated by an included gauge. This creates an environment equivalent to descending several thousand feet where air pressure is higher.
Can climbers use Gamow bags without special training?
No, proper training is required to use a Gamow bag safely and effectively. Users must understand how to recognize altitude sickness symptoms accurately, operate the inflation mechanism correctly without overinflating it, monitor patients while they are inside, and know when medical evacuation is necessary despite temporary relief provided by the device.
Are there any limitations or risks associated with using a Gamow bag for treating altitude sickness?
Yes, there are limitations and risks involved with using a Gamow bag. The treatment provides only temporary relief from symptoms; therefore its not a substitute for descending to lower altitudes or seeking professional medical care when available. Over-reliance on it may delay necessary descent or evacuation. Additionally improper use could lead to complications like claustrophobia or exacerbation of certain medical conditions due to increased pressure inside the chamber.
