🗑
|

| pH | represents a measurement of the overall acid-base balance and is used to assess the overall [H+] status of the blood
🗑
|
||||
| PaCO2 | represents the arterial CO2 level and is used to assess ventilatory status
🗑
|
||||
| PaO2 | represents the O2 tension level in the arterial blood and is used to evaluate the oxygenation status
🗑
|
||||
| HCO3 | Represents bicarbonate level, an important buffer in the blood, and is used to evaluate the metabolic aspect of acid-base balance
🗑
|
||||
| BE/BD | Represents the base excess (or deficit) level of the blood, and is used to indicate the metabolic aspect of acid-base balance
🗑
|
||||
| SaO2 | Represents the level of saturation of hemoglobin (Hb) with O2 and also provides a measure of arterial oxygenation
🗑
|
||||
| 7.35 – 7.45 | pH
🗑
|

| +/-2meq/L | BE/BD
🗑
|
||||
| acidic | High levels of CO2, Low pH (High H+ concentration, Low levels of HCO3
🗑
|
||||
| alkalotic | Low levels of CO2, High pH (Low H+ concentration), High levels of HCO3
🗑
|
||||
| pH and PaCO2 | are inversely related
🗑
|
||||
| pH and HCO3 | are directly related
🗑
|
||||
| What is COMPENSATION? | The altering of function of the respiratory or renal (metabolic) system in an attempt to correct for an acid-base disorder.
🗑
|
||||
| Hypoxemia | low levels of oxygen in the blood
🗑
|
||||
| 60-80mmHg | mild hypoxemia
🗑
|
||||
| 40-60mmHg | moderate hypoxemia
🗑
|
||||
| <40mmHg | severe hypoxemia
🗑
|
||||
| pH < 7.35 | acidic
🗑
|
||||
| pH >7.45 | alkalotic
🗑
|
||||
| PaCO2 < 35mmHg | alkalotic
🗑
|
||||
| PaCO2 > 45mmHg | acidic
🗑
|
||||
| HCO3 < 22meq/L | acidic
🗑
|

| Relationship between Minute Ventilation and ABG interpretation | As Minute Ventilation increases, PaCO2 will decrease and pH will increase (Alkalosis)
As Minute Ventilation decreases, PaCO2 will increase and pH will decrease (Acidosis)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
