Is potassium accurate on VBG?
Sodium and potassium Sodium levels across all pH states were marginally over-estimated by the VBG. Despite the over-estimation, there was high correlation (r=0.84–0.85) between the VBG and LBM. Table 1: VBG parameters. Potassium levels were marginally underestimated across all pH states.
Does ABG show potassium?
Conclusion: The agreement between ABG and venous potassium measurement are confirmed Clinicians can use ABG’s potassium level as a guideline for treatment instead of using the conventional venous potassium level.
Does VBG have potassium?
As such, we recommend that sodium, potassium and creatinine measurements can be used interchangeably between the VBG and LBM, with the exception of potassium levels in acidaemia. Potassium levels in acidaemia should be used with caution due to lower correlation.
How accurate is potassium on ABG?
By contrast, the ABG-measured potassium levels were on average 0.43 mmol/L lower than the laboratory measurement. While this was within the USCLIA cut-off of ±0.5 mmol/l, the 95% limits of agreement were −0.29 and 1.16. Thus, the ABG measurements of potassium were less accurate than the ABG hemoglobin measurements.
What is a normal potassium reading?
Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L ) can be life-threatening and requires urgent medical attention.
How accurate are electrolytes on VBG?
Conclusions: The VBG electrolytes were 97.8% sensitive and 100% specific for the diagnosis of DKA in hyperglycemic patients. These preliminary findings support the use of VBG electrolytes in lieu of VBG along with serum chemistry analysis to rule in or rule out DKA.
What are the normal ranges for arterial blood gases?
According to the National Institute of Health, typical normal values are:
- pH: 7.35-7.45.
- Partial pressure of oxygen (PaO2): 75 to 100 mmHg.
- Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg.
- Bicarbonate (HCO3): 22-26 mEq/L.
- Oxygen saturation (O2 Sat): 94-100%
Does VBG give electrolytes?
Is 139 sodium level high?
Normal sodium levels are usually between 136 and 145 millimoles per liter (mmol/L). Blood sodium levels below 136 mmol/L may mean you have low blood sodium (hyponatremia). Blood sodium levels greater than 145 mmol/L may mean you have blood sodium levels that are too high (hypernatremia).
What does a potassium level of 5.7 mean?
This is called hyperkalemia, or high potassium. According to the Mayo Clinic, a normal range of potassium is between 3.6 and 5.2 millimoles per liter (mmol/L) of blood. A potassium level higher than 5.5 mmol/L is critically high, and a potassium level over 6 mmol/L can be life-threatening.
