Interpretation of Blood Gas Measurements

Angiostrongylosis-related restrictive pneumopathy assessed by arterial blood gas analysis in a dog

“…7). From the arterial blood gas levels the restrictive character of the pathological process was concluded, which is presumably caused by the affected pulmonary parenchyma (Haskins, 2004). The lowest paO 2 level could be explained by the local inflammatory process triggered by the dying/dead lungworms in the pulmonary tissue.…”

“…Arterial blood gas analysis contributes to determining the type and severity of different respiratory disorders and helps monitor the course of pneumopathies (Haskins, 2004;Ford and Mazzaferro, 2006). Arterial hypoxaemia is diagnosed if the arterial pO 2 is less than 90 mmHg (Haskins, 2004).…”

“…Diffusion impairment is usually accompanied by low arterial pO 2 level and physiologic arterial pCO 2 level. These laboratory alterations reveal the restrictive nature of pulmonary disease (Haskins, 2004). When Beagle dogs were infected experimentally with A. vasorum, moderate hypoxaemia (median paO 2 Acta Veterinaria Hungarica 63, 2015 level of 73 mmHg and 74 mmHg, respectively) was detected 8 and 13 weeks after the inoculation (Kranjc et al, 2010).…”

“…Arterial hypoxaemia is diagnosed if the arterial pO 2 is less than 90 mmHg (Haskins, 2004). Diffusion impairment develops due to the thickening of the alveolar-capillary membrane in diffuse pulmonary interstitial disease or due to the loss of alveolar or capillary surface area when pulmonary interstitial oedema, fibrosis, vasculitis or emphysema develops.…”

Assessment of a point‐of‐care cardiac troponin I test to differentiate cardiac from noncardiac causes of respiratory distress in dogs

“…A second limitation in this study is that very few dogs had quantification of hypoxemia using an arterial blood gas sampling or by pulse oximetry. Arterial blood gas sampling may require additional restraint or sedation, either of which may exacerbate respiratory distress 34,35 . Pulse oximetry was not used for a number of reasons; first being its inherent insensitivity compared with arterial blood gas, second there is variation in its accuracy which may be dependant upon many factors including lighting, ease of probe placement, pigmented skin, hypotension, and dyshemoglobinemias 36 .…”
