instruction: how many people received a electrolyte administration procedure in the same hospital encounter after having received a non-invasive ventilation procedure in 2104?
response: SELECT COUNT(DISTINCT t1.uniquepid) FROM (SELECT patient.uniquepid, treatment.treatmenttime, patient.patienthealthsystemstayid FROM treatment JOIN patient ON treatment.patientunitstayid = patient.patientunitstayid WHERE treatment.treatmentname = 'non-invasive ventilation' AND STRFTIME('%y', treatment.treatmenttime) = '2104') AS t1 JOIN (SELECT patient.uniquepid, treatment.treatmenttime, patient.patienthealthsystemstayid FROM treatment JOIN patient ON treatment.patientunitstayid = patient.patientunitstayid WHERE treatment.treatmentname = 'electrolyte administration' AND STRFTIME('%y', treatment.treatmenttime) = '2104') AS t2 WHERE t1.treatmenttime < t2.treatmenttime AND t1.patienthealthsystemstayid = t2.patienthealthsystemstayid
