- In any routine patient-care situation where an IR tympanic, Oral/Rectal Electronic, or Temporal Artery-swipe thermometer can be employed, the Caregiver should perform well. In very-high acuity settings (such as NICU, ICU, CCU) the patients are almost always constantly monitored and the readings continuously reported and recorded by hardwire or wireless to the nurse’s station and other EHR collection locations. For “spot” temp checking, the Caregiver can certainly provide information in these or any routine medical setting.
