Description
Thitapa Luepiyapanich, Nitipatana Chierakul, Wanchai Dejsomritrutai, and Sutat Pipopsuthipaiboon studied in 2026 a breathing pattern called PRISm in Thai hospital patients, filling a Southeast Asian evidence gap. In PRISm, one breathing measure falls while the ratio between measures stays normal. Their cohort drew 1,300 adults tested at Siriraj Hospital in 2017 and 2018, followed through March 2024, with prevalence calculated under two competing definitions.
Depending on definition, prevalence ranged from a few percent up to about eight percent overall. People with PRISm were older and more often had heart failure, and their death risk ran more than double that of normal testers, staying significant after adjustment. Repeat testing showed the pattern is unstable: many people shifted to normal, obstructive, or restrictive patterns over time.
