Exertional Myopathy in a Juvenile Green Sea Turtle (Chelonia mydas) Entangled in a Large Mesh Gillnet

Table 1

Blood gas results from a large mesh gillnet entangled green sea turtle (Chelonia mydas). Values marked with “—” were not obtained. Initial sample was obtained at presentation and the recheck sample was performed approximately 4 hours later. Blood gas analysis performed using iSTAT CG4+ and CG8+ cartridges. Range values based on published iSTAT results of free-ranging juvenile green sea turtles [18, 19]. Temperature correction (TC) was performed at the turtle’s cloacal temperature (20.0°C) for pH, pCO₂, pO₂, and ionized calcium based on formulas presented in Anderson et al. 2011 [18].
