The Mean Airway Pressure (MAP) Calculator is a vital tool for clinicians managing patients on mechanical ventilation. It helps determine the average pressure applied to the airways and alveoli during a breath cycle, a key indicator for assessing respiratory mechanics and potential risks like barotrauma or hyperinflation. Use this calculator to quickly derive MAP from peak inspiratory pressure, PEEP, inspiratory time, and respiratory rate.
Formula:
The Mean Airway Pressure (MAP) is calculated using the following formula:
MAP = ((PIP - PEEP) * (Ti / Ttot)) + PEEP
Where:
- PIP = Peak Inspiratory Pressure (cmH₂O)
- PEEP = Positive End-Expiratory Pressure (cmH₂O)
- Ti = Inspiratory Time (seconds)
- Ttot = Total Cycle Time (seconds)
- Ttot = 60 / RR (where RR is Respiratory Rate in breaths/min)
