Arterial Blood Gases (ABG)

Definition

An arterial blood gases (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. This test is used to check how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood.

Arterial Blood Gases

pH	7.35 - 7.45
HCO3 (mEq/L)	22 - 26 (mEq/L)

Disease Severity Indicators

Acute Respiratory Distress Syndrome (ARDS) Severity

Definition

The Acute Respiratory Distress Syndrom (ARDS) severity levels are calculated using the Berlin Definition as follows:

• ARDS

- Mild ARDS: 200mmHg < PaO2/FiO2 ≤ 300 mmHg && (PEEP or CPAP ≥ 5 cmH2O) or non-ventilated.

- Moderate ARDS: 100mmHg < PaO2/FiO2 ≤ 200 mmHg && PEEP ≥ 5 cmH2O or non-ventilated.

- Severe ARDS: PaO2/FiO2 ≤ 100 mmHg && PEEP ≥ 5 cmH2O or non-ventilated.

• ARDS when PaO2 not available.

- SpO2/FiO2 ≤ 315 suggests ARDS (including non-ventilated patients)

Berlin Definition of ARDS
ARDS Severity		PaO2/FiO2
Mild		>200-300
Moderate		>100 - 200
Severe		≤100
*on positive end expiratory pressure (PEEP) ≥ 5 cm H2O

Modified Early Waring System (MEWS) Score

Definition

To calculate the Modified Early Warning System (Mews) score, we rank each one of values of the entries listed in the first column of Table Mews Calculation, based on where they fall in pre-defined ranges and then we sum-up all the ranks.

MEWS Score Range	Frequency of monitoring	Clinical Response
0-4	Minimum 12 hours	Continue to monitor and review MEWS every 12 hours
5-6	Minimum 4 hours	Consider notifying physician of MEWS score Notify charge nurse Consider placing a consult to Rapid Response Nurses Increase MEWS assessment every 4 hours with increased frequency in assessments
7+	Maximum per 2 hours	Consider calling Physician with current assessment data Consider calling a Rapid Response Call RRT Consult nurse Consider transferring to step-down or ICU

Modified Early Warning System (MEWS)
Feature	Value Range	Score
Respiratory Rate (bpm)	≤8	2
	9 - 14	0
	15 - 20	1
	21 - 29	2

	111 - 129	2

Systolic BP (mmHg)	≤ 70	3
	71 - 80	2
	81 - 100	1
	101 - 199	0
	≥ 200	2
Urine Output (ml/kg/h)	Nil	3
	< 0.5	2
Temperature (ºC)	≤ 35	2
	35.1 - 36	1
	36.1 - 38	0
	38.1 - 38.5	1
	≥ 38.6	2
Total:

Important Assumptions:  
1. When Urine Output is not inserted (i.e., NULL value), then the MEWS score is still computed assigning zero (0) points to Urine Output. 
2. To compute the Urine Output per hour we calculate the time difference between the present Urine Output entry and the last non-NULL entry.

Hscore

Definition

The Hscore generates a probability for the presence of secondary haemophagocytic lymphohistiocytosis (HLH)¹.

• Hscores greater that 169 are 93% sensitive and 86% specific for HLH.

• Hscores can be calculated using the online calculator.

Note that bone marrow haemophagocytosis is not mandatory for a diagnosis of HLH.²
