Many papers in the AJRCMB make efforts to translate basic cell and molecular insights to
the effects on airways in the whole animal. However, these efforts are often ffawed by an
overinterpretation of the functional measurements that rely on the empiric
variable,“enhanced pause” or Penh, which has been shown to be primarily related to
ventilatory timing and unrelated to airway resistance (1–3). We are quite concerned about

Many papers in the AJRCMB make efforts to translate basic cell and molecular insights to the effects on airways in the whole animal. However, these efforts are often ffawed by an overinterpretation of the functional measurements that rely on the empiric variable,“enhanced pause” or Penh, which has been shown to be primarily related to ventilatory timing and unrelated to airway resistance (1–3). We are quite concerned about the increasingly widespread (over 30 articles) and often uncritical applications of the Penh method that have appeared in recent years in the AJRCMB and its sister journal, the AJRCCM. This uncritical application of Penh has also spread to some of the world’s most prestigious scientific journals, including PNAS, Nature Medicine,
