Transvascular diaphragm pacing systems (TDPS) and methods are disclosed for providing respiratory therapy to a patient. The TDPS can provide rapid insertion and deployment of endovascular pacing electrodes in critically ill patients who require intubation and invasive PPMV in order to support the physiological requirements of the human ventilatory system. The systems and methods make best use of the contractile properties of the diaphragm muscle and prevent muscle disuse and muscle atrophy. This can be carried out by engaging the phrenic nerves using patterned functional electrical stimulation applied to endovascular electrodes that are temporarily and reversibly inserted in central veins of the patient, such as the left subclavian vein and the superior vena cava. The TDPS can be designed to seamlessly interface with any commercially available positive-pressure ventilatory assistance/support equipment such as is commonly in use in hospital intensive care units (ICU) for treating critically ill patients with breathing insufficiencies, pain, trauma, sepsis or neurological diseases or deficits.

Cough is a common experience and the most frequent reason why an individual seeks a visit to a physician. The prevalence of cough is about 10+% of the population. Cough is a manifestation of many aerodigestive tract disorders and especially consequential for serious lower airway diseases such as respiratory infections, chronic obstructive pulmonary disease (COPD) and asthma because increased coughing leads to emergency room visits and hospitalization. There is a need for methods to oversee coughing frequency in certain patients. Traditionally, all automated cough monitors have used cough sound as the signal for the measurement of cough. In the present invention movements of the diaphragm muscle, recorded by a motion sensor placed above the xiphoid process, are used for counting coughs. A device for such recordings is described and data were collected. This method is validated by using citric acid spray to trigger cough sounds and to show that the provoked acoustic signal is matched by the electronic signals from the movement sensors. The xiphoid process is a unique anatomical landmark for the non-acoustic detection of cough.
