Dataset description
The ALARM ("A Logical Alarm Reduction Mechanism") is a Bayesian network designed to provide an alarm message system for patient monitoring.
The alarm data set contains the following 37 variables:
CVP (central venous pressure): a three-level factor with levels LOW, NORMAL and HIGH.
PCWP (pulmonary capillary wedge pressure): a three-level factor with levels LOW, NORMAL and HIGH.
HIST (history): a two-level factor with levels TRUE and FALSE.
TPR (total peripheral resistance): a three-level factor with levels LOW, NORMAL and HIGH.
BP (blood pressure): a three-level factor with levels LOW, NORMAL and HIGH.
CO (cardiac output): a three-level factor with levels LOW, NORMAL and HIGH.
HRBP (heart rate / blood pressure): a three-level factor with levels LOW, NORMAL and HIGH.
HREK (heart rate measured by an EKG monitor): a three-level factor with levels LOW, NORMAL and HIGH.
HRSA (heart rate / oxygen saturation): a three-level factor with levels LOW, NORMAL and HIGH.
PAP (pulmonary artery pressure): a three-level factor with levels LOW, NORMAL and HIGH.
SAO2 (arterial oxygen saturation): a three-level factor with levels LOW, NORMAL and HIGH.
FIO2 (fraction of inspired oxygen): a two-level factor with levels LOW and NORMAL.
PRSS (breathing pressure): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
ECO2 (expelled CO2): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
MINV (minimum volume): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
MVS (minimum volume set): a three-level factor with levels LOW, NORMAL and HIGH.
HYP (hypovolemia): a two-level factor with levels TRUE and FALSE.
LVF (left ventricular failure): a two-level factor with levels TRUE and FALSE.
APL (anaphylaxis): a two-level factor with levels TRUE and FALSE.
ANES (insufficient anesthesia/analgesia): a two-level factor with levels TRUE and FALSE.
PMB (pulmonary embolus): a two-level factor with levels TRUE and FALSE.
INT (intubation): a three-level factor with levels NORMAL, ESOPHAGEAL and ONESIDED.
KINK (kinked tube): a two-level factor with levels TRUE and FALSE.
DISC (disconnection): a two-level factor with levels TRUE and FALSE.
LVV (left ventricular end-diastolic volume): a three-level factor with levels LOW, NORMAL and HIGH.
STKV (stroke volume): a three-level factor with levels LOW, NORMAL and HIGH.
CCHL (catecholamine): a two-level factor with levels NORMAL and HIGH.
ERLO (error low output): a two-level factor with levels TRUE and FALSE.
HR (heart rate): a three-level factor with levels LOW, NORMAL and HIGH.
ERCA (electrocauter): a two-level factor with levels TRUE and FALSE.
SHNT (shunt): a two-level factor with levels NORMAL and HIGH.
PVS (pulmonary venous oxygen saturation): a three-level factor with levels LOW, NORMAL and HIGH.
ACO2 (arterial CO2): a three-level factor with levels LOW, NORMAL and HIGH.
VALV (pulmonary alveoli ventilation): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
VLNG (lung ventilation): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
VTUB (ventilation tube): a four-level factor with levels ZERO, LOW, NORMAL and HIGH.
VMCH (ventilation machine): a four-level factor with levels ZERO, LOW, NORMAL and HIGH
