First In Room Blood Pressure

Search:

Description

The first non-artifact Mean Arterial Pressure (MAP) associated with the first non-artifact blood pressure containing both systolic and diastolic blood pressure values between Patient In Room and Patient Out of Room. If a blood pressure MAP value is not recorded then it will be computed based on the systolic and diastolic pressure values. Calculate mean arterial pressure (MAP) using this equation: (BaselineBloodPressureSystolic)*1/3 + (BaselineBloodPressureDiastolic)*2/3

Limitation

Dependent on non-missing and valid baseline systolic and diastolic values. There is a small chance that, due to the retrospective nature of the data, not all artifacts were removed.

Data quality is limited to individual site documentation accuracy, completeness, and variable mapping, which is performed by each site, independently. MPOG, as the coordinating center, reviews data quality at each data upload and monthly via Data Diagnostics and Case Validation tools. This review, while thorough, may not contain all data elements relevant to this phenotype and thus should be carefully reviewed by the user.

This phenotype will use BloodPressureObservations to retrieve the first non-artifact blood pressure values between Patient In Room and Patient Out Of Room containing both systolic and diastolic blood pressure values. If Patient In Room Start is not available then Anesthesia Start is used. If Patient Out of Room is not available then Anesthesia End is used.

If a blood pressure mean arterial pressure (MAP) value is not recorded then it will be computed based on the systolic and diastolic pressure values. Calculate MAP using this equation: (BaselineBloodPressureSystolic)*1/3 + (BaselineBloodPressureDiastolic)*2/3

If no valid values are found then NULL will be returned for all values.
