System and Method for Scheduling Pause Maneuvers Used for Estimating Elastance and/or Resistance During Breathing
First Claim
1. A method of providing breathing assistance, comprising:
- assisting a plurality of breaths for a patient using a breathing assistance system, the plurality of breaths including one or more pause breaths and one or more non-pause breaths, wherein the occurrence of pause breaths during the plurality of breaths is randomized;
during each pause breath, including a pause maneuver during which one or more valves of the breathing assistance system are closed to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system;
taking one or more measurements during or proximate the pause maneuver; and
determining one or more patient characteristic values based at least on the one or more measurements, the one or more patient characteristic values including values for at least one of an elastance and a compliance associated with the patient.

Abstract
A method of providing breathing assistance is provided. A plurality of a patient'"'"'s breaths are assisted using a breathing assistance system. The plurality of breaths may include one or more pause breaths and one or more non-pause breaths, and the occurrence of pause breaths during the plurality of breaths may be randomized. Each pause breath may include a pause maneuver during which one or more valves of the breathing assistance system are closed to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system. One or more measurements may be taken during or proximate the pause maneuver, and one or more patient characteristic values may be determined based at least on the one or more measurements. The one or more patient characteristic values may include values for at least one of an elastance and a compliance associated with the patient.

17. A method of providing breathing assistance, comprising:
-
assisting a plurality of series of breaths for a patient using a breathing assistance system, wherein each series of breaths includes a pause breath and a randomized number of non-pause breaths;
wherein each pause breath includes a pause maneuver during which one or more valves of the breathing assistance system are closed to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system; and
wherein each non-pause breath does not include the pause maneuver. - View Dependent Claims (18, 19, 20, 21, 22)

23. A system for providing breathing assistance, comprising:
-
a breathing assistance controller configured to assist a plurality of breaths for a patient, the plurality of breaths including one or more pause breaths and one or more non-pause breaths;
a scheduling module configured to randomize the occurrence of pause breaths among the plurality of breaths;
a pause maneuver controller configured to include a pause maneuver in each pause breath, the pause maneuver including closing one or more valves of the breathing assistance system to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system;
one or more measurement devices configured to take one or more measurements during or proximate the pause maneuver; and
a patient characteristic calculation module configured to calculate one or more patient characteristic values based at least on the one or more measurements, the one or more patient characteristic values including values for at least one of an elastance and a compliance associated with the patient. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A system for providing breathing assistance, comprising:
-
breathing assistance control means for assisting a plurality of breaths for a patient, the plurality of breaths including one or more pause breaths and one or more non-pause breaths;
pause scheduling means for randomizing the occurrence of pause breaths among the plurality of breaths;
pause controlling means for including a pause maneuver in each pause breath, the pause maneuver including closing one or more valves of the breathing assistance system to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system;
measuring means for taking one or more measurements during or proximate the pause maneuver; and
patient characteristic calculation means for calculating one or more patient characteristic values based at least on the one or more measurements, the one or more patient characteristic values including values for at least one of an elastance and a compliance associated with the patient.

instructions for assisting a plurality of breaths for a patient using a breathing assistance system, the plurality of breaths including one or more pause breaths and one or more non-pause breaths, wherein the occurrence of pause breaths during the plurality of breaths is randomized;
instructions for including a pause maneuver in each pause breath during which one or more valves of the breathing assistance system are closed to create a constant volume defined at least by the patient'"'"'s lungs and one or more components of the breathing assistance system;
instructions for taking or receiving one or more measurements during or proximate the pause maneuver; and
instructions for determining values for at least one of an elastance and a compliance associated with the patient based at least on the one or more measurements. - View Dependent Claims (35)
