Calculations

Calculations can be performed using automatically-entered values or

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, cmH

O 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 cmH

O before calculating output values.
