instruction: is the systemicsystolic of patient 018-95228 second measured on the first icu visit less than its value first measured on the first icu visit?
response: SELECT (SELECT vitalperiodic.systemicsystolic FROM vitalperiodic WHERE vitalperiodic.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '018-95228') AND NOT patient.unitdischargetime IS NULL ORDER BY patient.unitadmittime LIMIT 1) AND NOT vitalperiodic.systemicsystolic IS NULL ORDER BY vitalperiodic.observationtime LIMIT 1 OFFSET 1) < (SELECT vitalperiodic.systemicsystolic FROM vitalperiodic WHERE vitalperiodic.patientunitstayid IN (SELECT patient.patientunitstayid FROM patient WHERE patient.patienthealthsystemstayid IN (SELECT patient.patienthealthsystemstayid FROM patient WHERE patient.uniquepid = '018-95228') AND NOT patient.unitdischargetime IS NULL ORDER BY patient.unitadmittime LIMIT 1) AND NOT vitalperiodic.systemicsystolic IS NULL ORDER BY vitalperiodic.observationtime LIMIT 1)
