What are the signs of patient-ventilator dyssynchrony?
What will be an ideal response?
When signs of patient-ventilator dyssynchrony occur, decisions about ventilator management require a competent physical assessment. The first physical sign of increased WOB is tachypnea (f>20/min) and a general appearance of agitation. Other physical signs of respiratory muscle stress include use of accessory respiratory muscles, intercostal retractions, and active expiration (use of abdominal muscles). In time, depending on a patient's pulmonary reserve and nutritional status, signs of respiratory muscle weakness or fatigue can develop.
