WebApr 23, 2024 · Diaphragm dysfunction is defined by a value of twitch tracheal pressure in response to magnetic phrenic stimulation (twitch pressure) amounting to less than 11 cmH2O. This study assessed whether this threshold or a lower one would predict accurately weaning failure from mechanical ventilation. Twitch pressure was compared to … WebAlternatively, some investigators advocate twitch stimulation of the phrenic nerve, measuring change in airway pressure in response to a standardized brief stimulation. This provides a measure of diaphragm strength, although the stimulation is not sufficient for maximal activation and therefore is not directly measuring PiMax ( 23 , 29 ).
WebAirway pressure is more conveniently measured than alveolar pressure. Peak inspiratory pressure (PIP) is displayed on most ventilators. A maximum acceptable PIP of <35 cmH20 is widely used. Alveolar … WebJun 13, 2024 · A noninvasive estimate of P di,tw can be obtained by measuring pressure changes in the upper airway or the mouth (P mo,tw) although oesophageal twitch pressure (P oes,tw) and thus P mo,tw are more influenced by lung volume than P di,tw. Resting values of P ga,tw have a slightly higher variability (CV 9–10%) than P di,tw (6%).
