Description

Currently, blood_gas_first_day.sql in MIMIC-III doesn't use the following items in D_LABITEMS table that looks to be related to blood gases.
Is it intentional or should we add these items?

 	row_id 	itemid 	label 			fluid 			category 	loinc_code
156 	30 	50829 	Fluid Type 		Other Body Fluid 	Blood Gas 	14725-6
157 	31 	50830 	pCO2, Body Fluid 	Other Body Fluid 	Blood Gas 	2023-0
158 	32 	50831 	pH 			Other Body Fluid 	Blood Gas 	2748-2
159 	33 	50832 	pO2, Body Fluid 	Other Body Fluid 	Blood Gas 	2706-0
160 	34 	50833 	Potassium 		Other Body Fluid 	Blood Gas 	2821-7
161 	35 	50834 	Sodium, Body Fluid 	Other Body Fluid 	Blood Gas 	2950-4
741 	742 	51544 	VOIDED SPECIMEN 	OTHER BODY FLUID 	BLOOD GAS 	NaN

Start with mimic-iii/concepts/firstday/blood_gas_first_day.sql and inspect how it selects blood-gas item IDs from D_LABITEMS. Compare that logic with the listed item IDs and labels, then verify that the resulting scope matches the intended first-day blood-gas concept and that the issue’s inclusion question is resolved.
