High-altitude solutions

At high altitude, low oxygen strains the body, causing acute altitude sickness and worsening sleep or heart issues. Symptoms often mimic other emergencies, complicating triage. For hospitals in Xizang, this means unique care challenges.

One of Zhang's priorities has been addressing how altitude-related illnesses were handled. Previously, patients suffering from altitude sickness were treated alongside general emergency cases, often leading to delays and confusion.

In 2025, the hospital launched the High-altitude Sickness Treatment Center, separating altitude-related cases from the emergency department. According to Zhang, the center treated more than 10,000 cases in its first six months, providing affordable and effective care to locals and visitors.

Emergency department director Liu Mingsen said the change was transformative. With clearer triage and dedicated staff, patients with altitude-related symptoms could receive timely treatment. For tourists, he added, the center has made their travels worry-free.

The hospital also established a High-altitude Sleep Medicine Center to address sleep-related issues exacerbated by Xizang's thin air. The center has treated over 600 patients and filled a critical gap in regional healthcare.

Infrastructure practice

Zhang has overseen several landmark initiatives designed to address structural gaps in Xizang's healthcare. The High-Altitude Health Management Center, for example, received more than 106,000 patients from July to the end of December in 2025, many seeking treatment for altitude sickness. According to Liu Mingsen, a onehour oxygen inhalation session is just 6 yuan, with the overall cost of a visit around 40 to 50 yuan.

The hospital also opened a Day Surgery Center, where visiting ophthalmologists from Beijing Tongren Hospital performed 97 cataract surgeries within six months. Zhang said day surgeries, with shorter recovery times, are well-suited to the demands of high altitude environments.

Other practical additions include a 24-hour Animal Bite Clinic, which consolidated wound treatment and vaccination services. The clinic has handled over 2,000 cases, about half of Lhasa's annual total.

For patients like Li Yueyun, a migrant worker from Sichuan province who often experiences altitude sickness, the specialized treatment center has eased the challenges of living and working in Lhasa. She said the availability of affordable, round the clock oxygen and treatment has been a significant help.

Measurable progress

Under Zhang's leadership, Lhasa People's Hospital has developed into a more capable tertiary hospital, with improved medical services, management, and facilities. For locals, this has reduced the need to travel far for advanced care.

These changes reflect the broader trends linked to China's medical aid initiative in Xizang. Regional health commission data from November 2025 shows that more than 2,400 medical professionals have supported Xizang's healthcare development since 2015. In that time, maternal mortality rates in the region have fallen from 108.86 per 100,000 live births to 48, while infant mortality declined from 16.81 per 1,000 live births to 7.6. Average life expectancy has risen to over 72.

Tan Xiangdong, deputy director of the regional health commission, noted that paired assistance among 184 hospitals nationwide has strengthened talent training and hospital management through mentorship programs. He cited thousands of development plans, research projects, practice integrations, and academic exchanges as evidence of growing institutional capacity.

He added that these efforts have produced even more development plans, research projects, advanced practices, and academic exchanges, greatly elevating local medical capacity.

Within that larger effort, Zhang's work at Lhasa People's Hospital offers a case study in how national policy is translated into local practice.
