Abstract
A respiratory therapy apparatus includes components operable to simultaneously provide a High Frequency Chest Wall Oscillation (HFCWO) therapy and a Mechanical Insufflation/Exsufflation (MIE) therapy to a patient. The respiratory therapy apparatus includes a controller that controls a synchronization of the HFCWO therapy and the MIE therapy to provide respiratory therapy to the patient to effectively clear mucous or induce deep sputum from the lungs of patient.
Claims22
A respiratory therapy apparatus comprising
- a housing;
- a high frequency chest wall oscillator (HFCWO) supported in the housing and operationally coupled to a garment worn on a torso of a patient to deliver a HFCWO therapy to the patient, the HFCWO therapy comprising application to the garment of a first baseline positive pressure and pressure oscillations relative to the first baseline positive pressure;
- a mechanical insufflator/exsufflator (MIE) supported in the housing and coupled to the patient's airway via a patient interface to deliver MIE therapy to the patient, the MIE therapy comprising cycles of a positive insufflation pressure and a negative exsufflation pressure applied to the patient's airway via the patient interface;
- and
- a controller situated in the housing and operable to control the HFCWO therapy and the MIE therapy, wherein during application of the negative exsufflation pressure to the patient's airway, the controller signals the HFCWO to apply a second baseline positive pressure to the garment thereby to provide an extra squeeze to the patient's torso during application of the negative exsufflation pressure to the patient's airway, wherein the pressure oscillations of the HFCWO therapy are turned off by the controller during the extra squeeze.
A respiratory therapy apparatus comprising
- a housing;
- a first therapy delivery apparatus situated in the housing and operable to provide a first respiratory therapy to a patient;
- a second therapy delivery apparatus situated in the housing and operable to provide a second respiratory therapy to the patient;
- and
- a controller operable to control the first therapy delivery apparatus and the second therapy delivery apparatus to deliver a respiratory therapy to the patient, wherein during the first and second respiratory therapy, an oscillatory positive pressure having a first baseline pressure is provided to the patient's torso as part of the first respiratory therapy while a positive pressure is applied to the patient's airway as part of the second respiratory therapy and a nonoscillatory positive pressure squeeze at a second baseline pressure is provided to the patient's torso as part of the first respiratory therapy while a negative pressure is applied to the patient's airway as part of the second respiratory therapy, the second baseline pressure being greater than the first baseline pressure.
