CaO2SaO2 x 134 x Hb. Alveolar Gas Equation The alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus PAO2PAO2PBPH2OFiO2PaCO2Rwhere PB is the barometric pressure PH2O is the water vapor pressure usually 47mmHg FiO2 is the fractional concentration of inspired oxygen and R is the gas exchange ratio.
Each scenario is broken down using a structured approach to ABG interpretation.
Abg equations. Interpretation of Arterial Blood Gases answers are found in the Pocket ICU Management powered by Unbound Medicine. Thank you for everything you do. If HCO3 is above 26 it is alkalosis.
In order to easily solve arterial blood gas problems the Tic Tac Toe or ROME. A detailed explanation of the alveolar gas equation occurs elsewhere. The normal range for HCO3 is from 22 to 26.
We take a range of 75-100. A collection of 10 arterial blood gas ABG interpretation scenarios to put your knowledge to the test. Arterial Blood Gas ABG values.
Available for iPhone iPad Android and Web. If the observed compensation is not the expected compensation it is likely that more than one acid-base disorder is present. 736 – 744 Sodium Na.

MEqL 22 – 26 mEqL Chloride Cl-. It is the dedication of healthcare workers that will lead us through this crisis. So a normal person should have a PaO 2 of around 99 mmHg.
ABG worked examples Weve included two worked ABG examples below. Obviously other equations besides those in Table 1 can be important in assessing disordered physiology. The point is not to belabor equations but to emphasize a few key relationships often overlooked or misapplied in the daily practice of medicine.
ABG also helps in differentiating between lung injury vs. Once youve worked through them head over to our ABG quiz for some more scenarios to put your newfound ABG interpretation skills to the test. Properly obtaining ABG sample Values.
This application can also distinguish between either causes of A-a gradient disturbances from the ABG parameters you will. An ABG Calculator like the one above is a piece of software that can be used to quickly calculate the interpretation of a sample set of ABG results. DEFINITION It is a diagnostic procedure in which a blood is obtained from an artery directly by an arterial puncture or 3.
The Arterial Blood Gas ABG Analyzer interprets ABG findings and values. 10 arterial blood gas problems worked using the tic-tac-toe method. Met acidosis or chronic resp alkosis ABG 730308015 appropriate resp compensation.
Mm Hg 36 – 44 mm Hg Bicarbonate HCO 3-. Calculate the anion gap if a metabolic acidosis exists. This is an unprecedented time.
MEqL P CO 2. In this post weve listed out some of our premium ABG Practice Questions for the TMC Exam. The topic of Arterial Blood Gases is one of the most important sections of the TMC Exam.
PAO2 FiO2 760 – 47 – PaCO2 125 PAO2 149 – PaCO2 x 125 Thus the patient with a relatively normal PaCO 2 say 40. ARDS by equations also included in this app. Method is the best way for doing this.
Based on the given ABG values HCO3 is above. Its designed to help students master ABG Interpretation. 1011 Henderson Hasselbal ch equation pH is the acidity in the blood pK a H2CO3 is the.
Expected HCO 3 24 Actual pCO 2 – 40 10 CommentThe increase in CO 2 shifts the equilibrium between CO 2 and HCO 3 to result in an acute increase in HCO 3. AG Na- Cl- HCO 3 – -12 2. The 1 for 10 Rule for Acute Respiratory Acidosis The HCO 3 will increase by 1 mmoll for every 10 mmHg elevation in pCO 2 above 40 mmHg.
If you are unfamiliar with the Tic Tac Toe method for ABGs to read the recommended article to learn how to do it. ABG it is always wise to check for the consistency of the report by the modified Hend erson equation. Based on the given ABG values PaCO2 is above 45 so it is considered ACIDOSIS.
A normal anion gap is approximately 12 meqL. Oxygenation PaO 2 The PaO 2 is low so we know the patient is in respiratory failure however we dont yet know what type.
