the ratio of the duration of inspiration to the duration of expiration. A range of 1:1.5 to 1:2 for an adult is considered acceptable for mechanical ventilation. Ratios of 1:1 or higher may cause hemodynamic complications, whereas ratios lower than 1:2 indicate lower mean airway pressure and fewer associated hazards.
In respiratory therapy or mechanical ventilation, the ratio of a patient's inspiratory to expiratory time.
Patient discussion about I:E ratio
Q. Q. I want to know about urine protein creatine ratio in diagnosing nephrotic syndrome. Please explain interms of unit such as mg/mg or mmol/mg. Normal range, nephrotic range with good referrence.
A. Nephrotic syndrome is defines as a damage to the kidneys, in which there is a leak of large amounts of protein (over 3.5 grams of protein / 24 hours urine output) from the blood to the urine. Protein loss causes low protein count in the blood (hypoalbuminemia) and edemas (excess fluid in the interstitial cavity which is between the cells, causes leg swelling most often, and also in the adbomen and around the eyes).More discussions about I:E ratio
