According to the AHDI, when the term “millimeters of mercury” is dictated with a blood pressure reading or ocular tension, it should be transcribed as mmHg.
Explanation:
The term ‘millimeters of mercury’ represents the unit for pressure. According to the transcription rules by AHDI, units of measures should be abbreviated when it accompanies a numeral.
So, when it is dictated as 20 millimeters of mercury it should be transcribed or edited as 20 mmHg, where mm is the unit for millimeter and Hg the symbol of mercury.
This term is used by the healthcare professionals to specify the blood pressure of an individual, where both the systolic and diastolic readings are mentioned. For example, the patient’s blood pressure is 120/80 mmHg.
