Portable altitude chambers (PACs), a piece of equipment used to treat altitude sickness, have saved the lives of more than 70 mountain hikers nationwide since 2012, the Taiwan Wilderness Medical Association said.
Mountain hiking brings many health benefits, allowing people to boost their physical strength while enjoying natural scenery and has become a popular leisure activity over the past few years.
However, altitude sickness can occur during mountain hikes and its fatality should not be taken lightly, experts have said.

Wang Shih-hao (王士豪), a doctor specializing in altitude sickness, said that people with high-altitude sickness could experience symptoms such as feeling drunk or having difficulty breathing.
Altitude sickness can be relieved shortly after a person is put inside a PAC, as the air pressure inside a PAC simulates conditions found at a lower altitude.
Wang’s interest in studying altitude sickness arose after he was rescued from a mountaineering incident in his school years.
The Yushan National Park Headquarters in 2012 adopted Wang’s suggestion to install a PAC at the Jiaming Lake Lodge (嘉明湖山屋), which saved the life of a hiker.
The incident inspired Wang to jointly establish the Taiwan Wilderness Medical Association with experts and well-wishers the following year, raising NT$8 million (US$244,312) to purchase 100 PACs.
Association secretary Lin Mei-chun (林美君) said tailor-made storage buckets for the 100 PACs were purchased.
However, the buckets were blue, and commonly mistaken for trash bins, with hikers dumping food waste in them, she said.
Some PACs became moldy and malfunctioned due to the food waste, while the smells attracted black bears to search for food around the sites and damage the equipment, Lin said.
Fortunately, many kind-hearted people over the years have helped the association replace the blue buckets with red ones, which are expected to decrease the likelihood of PACs being damaged, she said.
Association secretary-general Hsu Yan-hui (徐彥輝) said that with the help of the government, as of last year, 38 mountain cabins nationwide are now equipped with PACs.
Data showed that these PACs have saved the lives of more than 70 mountain hikers since 2012, he said, adding that the real number might be more than 100, as not every hiker would have registered their use of the equipment.
A mountain hiker from Keelung, surnamed Tai (戴), had an oxygen saturation level of only 50 percent while on the way to visit Jiaming Lake in 2021.
He was saved after his tour guide put him inside a PAC installed at the mountain cabin they were staying in, Hsu said, adding that Tai, wishing to express gratitude for his life being saved, has donated money to the association every month over the past four years.
Aside from being installed at mountain lodges, some of the 100 PACs were given to mountain rescue-related fire brigades and rescue agencies free of charge to help save lives, the association said, adding that other PACs are being operated by the association to train the public in how to use them.
Although instructions are provided on a poster on the wall behind every installed PAC, operating it could still be challenging, an association worker said.
However, the association has limited resources, volunteers do not frequently go to the mountains to conduct maintenance and it is difficult to install PACs at remote mountain lodges without the use of a helicopter, he said.
Therefore, people are advised to learn about the equipment online or take part in a PAC training course to be able to properly use the equipment in case of an emergency, they said.
Hikers should learn how to use PACs before they hike in the mountains, as the PAC instructions on the posters in the cabins are not guaranteed to be intact and Internet connections are mostly unavailable in the mountains, Hsu said.
WANG RELEASED: A police investigation showed that an organized crime group allegedly taught their clients how to pretend to be sick during medical exams Actor Darren Wang (王大陸) and 11 others were released on bail yesterday, after being questioned for allegedly dodging compulsory military service or forging documents to help others avoid serving. Wang, 33, was catapulted into stardom for his role in the coming-of-age film Our Times (我的少女時代). Lately, he has been focusing on developing his entertainment career in China. The New Taipei District Prosecutors’ Office last month began investigating an organized crime group that is allegedly helping men dodge compulsory military service using falsified documents. Police in New Taipei City Yonghe Precinct at the end of last month arrested the main suspect,
A cat named Mikan (蜜柑) has brought in revenue of more than NT$10 million (US$305,390) for the Kaohsiung MRT last year. Mikan, born on April 4, 2020, was a stray cat before being adopted by personnel of Kaohsiung MRT’s Ciaotou Sugar Refinery Station. Mikan was named after a Japanese term for mandarin orange due to his color and because he looks like an orange when curled up. He was named “station master” of Ciaotou Sugar Refinery Station in September 2020, and has since become famous. With Kaohsiung MRT’s branding, along with the release of a set of cultural and creative products, station master Mikan
LITTORAL REGIMENTS: The US Marine Corps is transitioning to an ‘island hopping’ strategy to counterattack Beijing’s area denial strategy The US Marine Corps (USMC) has introduced new anti-drone systems to bolster air defense in the Pacific island chain amid growing Chinese military influence in the region, The Telegraph reported on Sunday. The new Marine Air Defense Integrated System (MADIS) Mk 1 is being developed to counter “the growing menace of unmanned aerial systems,” it cited the Marine Corps as saying. China has constructed a powerful defense mechanism in the Pacific Ocean west of the first island chain by deploying weapons such as rockets, submarines and anti-ship missiles — which is part of its anti-access/area denial (A2/AD) strategy against adversaries — the
Eleven people, including actor Darren Wang (王大陸), were taken into custody today for questioning regarding the evasion of compulsory military service and document forgery, the New Taipei District Prosecutors’ Office said. Eight of the people, including Wang, are suspected of evading military service, while three are suspected of forging medical documents to assist them, the report said. They are all being questioned by police and would later be transferred to the prosecutors’ office for further investigation. Three men surnamed Lee (李), Chang (張) and Lin (林) are suspected of improperly assisting conscripts in changing their military classification from “stand-by
