Once activated, they send action potentials through large myelinated fibers of the vagus nerve to the inspiratory area in the medulla and apneustic center of the pons.
42.
Identifying the steadiest portion of the inspiratory flow ( F ) waveform fit the corresponding portion of the airway pressure ( Paw ) waveform in the following power equation:
43.
The apneustic center of pons sends signals to the medulla to delay the'switch off'signal of the inspiratory ramp provided by the pneumotaxic center of pons.
44.
"' Catathrenia "'is a rapid eye movement sleep parasomnia consisting of end-inspiratory apnea ( breath holding ) and expiratory groaning during sleep.
45.
Inspiratory muscle training has also decreased severe fatigue perception in subjects with early stages of sarcoidosis, as well as improving functional and maximal exercise capacity and respiratory muscle strength.
46.
Altering the % inspiratory time ( T % i ) changes the proportion of the time in which the vibration or sound wave is above the baseline versus below it.
47.
Josef Breuer and Ewald Hering reported in 1868 that a maintained distention of the lungs of anesthetized animals decreased the frequency of the inspiratory effort or caused a transient apnea.
48.
PIP is the Peak Inspiratory Pressure ( the pressure difference between the ventilator and the lungs results in inflation until the peak pressure is attained, and passive exhalation follows)
49.
For forced expirations inspiratory manoeuvres correlation coefficients for peak flow were r?0.84, FEV1 0.95, FEF75 0.76 and FEF50 0.69.
50.
The performance of a regulator is measured by the and work of breathing, and the capacity to deliver sufficient breathing gas at peak inspiratory flow rate at high ambient pressures.
