One hour later, the infant showed severe dyspnea with oxygen saturation decreased, ABG (pH = 7.24, PaO2 = 72mmHg, PaCO2 = 44mmHg, BE = -8.33, FiO2 = 50%, Hb = 106.9g/L) suggested acidosis. Following intubation, a bedside CXR was performed, which showed an...
ABG Not required If performed, negative for acidemia Findings of hypercapnia and/or hypoxemia No respiratory acidosis, i.e., pH≥ 7.35 Respiratory acidosis, i.e.: PaCO2 > 45 mm HgAND pH < 7.35 Research to validate the thresholds of clinical variables is ongoing. Use clinical judgment ...

Alternatively venous blood gases have shown a good correlation with arterial blood gases in many clinical situations and specifically in diabetic ketoacidosis, exacerbation of chronic respiratory failure, uremic acidosis, or multiple trauma. Furthermore, in some clinical scenarios with severe circulatory ...

When evaluating a child with respiratory failure, one should be aware that a child with prominent respiratory symptoms may have non-respiratory disease (i.e. metabolic acidosis, DKA) and conversely, advanced respiratory failure may be present in a child with no respiratory distress (central ...
Acuteliverfailure (ALF) is a severe condition characterized by rapidly progressiveliverinjury, hepatic encephalopathy , and impaired synthetic function, which results in coagulopathy . The most common causes are infections (e.g., viral hepatitis ...
gradient for oxygen, respiratory alkalosis, and hypocapnia are common findings on arterial blood gas (ABG) as a pathophysiological response to PE. Notably, respiratory or lactic acidosis is uncommon but can be present in patients with massive PE associated with obstructive shock and respiratory arrest...
Ventilation was initiated using a tidal volume of 10 mL/kg, a respiratory rate of 12 to 16 breaths/minute, a positive end-expiratory pressure of 5 cmH2O, and an FiO2 of 0.40. Systemic arterial blood gases (ABG) and lung compliance were measured every hour for the duration of the ...
