  • Apparatus and method for determining and displaying functional residual capacity data and related parameters of ventilated patients
    Patent number: 7530353
    Abstract: A ventilator for ventilating a patient has means integrated therewith for carrying out a determination of the functional residual capacity of the patient using an inert gas wash in/wash out technique. To this end, the ventilator operates to alter the inert gas content of breathing gases provided to the patient. The amount of inert gas expired by the patient is obtained and used to determine functional residual capacity on a breath-by-breath basis. A graph of the functional residual capacities for a given number of breaths is produced. Thereafter, the inert gas levels in the breathing gases are returned to the original levels and further functional residual capacity determinations and a graph of same provided. The functional residual capacity information may also be provided in tabular form. A log of functional residual capacity determinations and ventilator settings or patient treatments affecting same may also be provided.
