Performing and Reviewing Calculations

Performing Calculations can be performed using automatically-entered values or Calculations manually-entered values. If a parameter is being continuously monitored,

its value is automatically entered. Values which are not monitored must be entered manually. You can also change any of these values if needed.

In hemodynamic calculations, if the systolic and diastolic pressures are manually entered via the cursor keys or the handheld keypad, the mean pressure is calculated, marked with an asterisk, and stored automatically. The following formula will be used to estimate the mean pressure:

systolic + (diastolic x 2) / 3

Both indexed and non-indexed values are calculated. Calculated and input values are first presented with their associated units. If desired, the units column for calculated values may be replaced with normal ranges, and the input units column may be replaced with the times at which the values were stored in the database.

Parameters that are sourced in kPa, cmH2O or mbar are automatically converted into mmHg to provide consistent indexed and non-indexed calculation units. Ventilation calculations convert input pressures from mmHg, kPa, and mbar into cmH2O before calculating output values.
