Necessary adjustments were performed according to arterial blood gas analysis. After the patients could spontaneously breathe, the mechanical respiratory rate was reduced by 8 and 4 sequentially.
In addition, blood gas analysis shows proper blood oxygenation as compared to low-flow priapism, which shows ischemic pattern (6, 7).
Respiratory function tests, pulse oximetry readings, arterial blood gas analysis, electrocardiography, non-stress test were normal.
The substitution of venous for arterial sampling during blood gas analysis has been evaluated with cardiac arrest, chronic obstructive pulmonary disease, diabetic ketoacidosis, and miscellaneous forms of acute respiratory failure.
Blood gas analysis is the gold standard for assessment, monitoring, evaluation of acid base status and adequacy of oxygenation and ventilation of patients suffering a wide range of metabolic and respiratory disturbances, both acute and chronic, particularly in patients on mechanical ventilation.
Isosulfan blue stain-induced methemoglobinemia was diagnosed based on knowledge of the use of the stain due to the characteristics of the surgical procedure, the high methemoglobin concentration both in arterial blood gas analysis and in further biochemical blood analysis, and the decrease in Sp[O.sub.2] saturation regardless of normal Pa[O.sub.2].
Blood gas analysis immediately before the start of the extracorporeal lung assistance revealed a [P.sub.a]C[O.sub.2] of 88 mmHg with a pH of 7.30, and Pa[O.sub.2] was 90 mmHg.
Blood gas analysis showed a pH of 7.29, PC[O.sub.2] of 23.2 mmHg, P[O.sub.2] of 64.5 mmHg, HC[O.sup.-.sub.3] of 13.5 mmol/L, base excess of -14.4 mmol/L, and lactate level of 9.6 mmol/L, suggesting lactic acidosis.
