DOI: 10.1093/sleep/zsad077.0427
Abstract: Obstructive sleep apnea (OSA) is characterized by repetitive episodes of pharyngeal obstruction at one or more collapse sites. Multilevel collapse is a negative predictive factor for PAP-alternative surgical treatments. Pharyngeal manometry during drug-induced sleep endoscopy… read more here.

DOI: 10.1093/sleep/zsw005
Abstract: Objectives Pharyngeal critical closing pressure (Pcrit) or collapsibility is a major determinant of obstructive sleep apnea (OSA) and may be used to predict the success/failure of non-continuous positive airway pressure (CPAP) therapies. Since its assessment… read more here.

DOI: 10.1098/rsbl.2022.0342
Abstract: The critical oxygen tension of whole-animal oxygen uptake rate, or Pcrit, has historically been defined as the oxygen partial pressure (PO2) at which aerobic scope falls to zero and further declines in PO2 require substrate-level… read more here.

DOI: 10.1242/jeb.163717
Abstract: ABSTRACT Pcrit – generally defined as the PO2 below which the animal can no longer maintain a stable rate of O2 consumption (ṀO2), such that ṀO2 becomes dependent upon PO2 – provides a single number… read more here.

DOI: 10.1242/jeb.228098
Abstract: ABSTRACT Standard metabolic rate (SMR), maximum metabolic rate (MMR), absolute aerobic scope (AAS) and critical oxygen tension (Pcrit) were determined for the Gulf killifish, Fundulus grandis, an ecologically dominant estuarine fish, acclimated to lowered salinity,… read more here.
