What are the normal ranges for blood bicarbonate?

Results are given in milliequivalents per liter (mEq/L) or millimoles per L (mmol/L). Normal bicarbonate levels are: 23 to 30 mEq/L in adults.

What are the normal values of ABGS?

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%

What is the normal acidosis?

The pH of your blood should be around 7.4. According to the American Association for Clinical Chemistry (AACC), acidosis is characterized by a pH of 7.35 or lower. Alkalosis is characterized by a pH level of 7.45 or higher.

What are the levels for respiratory acidosis?

Respiratory acidosis occurs when an increase in PaCO2 develops secondary to impairments in breathing that result in a pH of less than 7.35, as measured in blood taken from an artery. In chronic respiratory acidosis, the PaC02 may be elevated with a normal blood pH (in the range of 7.35 to 7.45).

Is 20 a low CO2 level?

A normal result is between 23 and 29 mmol/L. A low CO2 level can be a sign of several conditions, including: Kidney disease. Diabetic ketoacidosis, which happens when your body’s blood acid level goes up because it doesn’t have enough insulin to digest sugars.

How do you evaluate ABG values?

Analysis and interpretation of basic ABG values can be determined by the following steps.

  1. Examine the pH level. If pH falls below normal (less than 7.35) the patient is acidotic; if it rises above normal (more than 7.45) the patient is alkalotic.
  2. Examine the PaCO2 level.
  3. Examine the HCO3 and PaO2 levels.

How do you manage respiratory acidosis?

Treatment is aimed at the underlying disease, and may include:

  1. Bronchodilator medicines and corticosteroids to reverse some types of airway obstruction.
  2. Noninvasive positive-pressure ventilation (sometimes called CPAP or BiPAP) or a breathing machine, if needed.
  3. Oxygen if the blood oxygen level is low.
