Anesthesia Time Calculator



Calculating anesthesia time is crucial for medical professionals to ensure accurate dosages and patient safety during procedures. An Anesthesia Time Calculator simplifies this process, providing a user-friendly tool for healthcare practitioners. In this article, we’ll guide you on how to use and implement an Anesthesia Time Calculator using HTML and JavaScript.

How to Use

  1. Input the start time of anesthesia in the provided field.
  2. Enter the end time of anesthesia in the designated box.
  3. Click the “Calculate” button to obtain the precise anesthesia time.


Anesthesia Time = End Time – Start Time
