Abstract: A method of determining respiratory rate from a photoplethysmograph signal includes filtering the photoplethysmograph signal to create a filtered photoplethysmograph signal. The method also includes detecting peaks and valleys in the filtered photoplethysmograph signal to extract predetermined features from the filtered photoplethysmograph signal. The method also includes obtaining variation waveforms from the predetermined features. The method also includes removing outliers from each of variation waveforms. The method also includes interpolating for the outliers removed from each of the variation waveforms to acquire a frequency estimation of each of the variation waveforms. The method also includes determining a respiratory rate based on the frequency estimation of each of the variation waveforms. The method also includes determining a weighted average of the respiratory rate the variation waveforms to determine an estimated respiratory rate.

Abstract: A patient support apparatus includes a frame and a mattress positioned on the frame. A respiratory therapy device is coupled to the frame. The respiratory therapy device includes a blower having an inlet and an outlet, a patient interface, and a valve including a valve member that is rotatable through a first angular displacement in a first direction from a first position to a second position. The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position.

Abstract: A respiratory acoustic analysis system for sensing and analyzing respiratory sounds of a patient may include a High Frequency Chest Wall Oscillation (HFCWO) vest, at least one sensor coupled with the HFCWO vest, and an algorithm stored in a processor for processing sensed data from the at least one acoustic sensor to provide processed data describing the respiratory sounds of the patient, in a form that can be used by a physician or other user.
