1 Maximum static inspiratory and expiratory mouth pressures are the most commonly performed tests of respiratory muscle strength.
2Transdiaphragmatic pressure----Calculated by subtracting endoesophageal pressure from gastric pressure.
3Phrenic nerve stimulation test----Most commonly employed technique ofelectrophrenic stimulation employs a frequency of one pulse per second to measure transdiaphragmatic contraction during
4 Analysis of rib cage and abdomen for paradoxical inward motion.
5Spirometry----A decrease in vital capacity greater than 25 percent on moving from upright to supine posture is a sign of diaphragmatic weakness.
6ABG---Paco2 increases when respiratory muscle strength is less than 50 percent of the predicted value.
7MVV is an index of respiratory muscle strength in presence of normal expiratory flow ratesn
