WebDuring exercise, tidal volume increases as the depth and rate of breathing increase. This has the effect of taking more oxygen into the body and removing more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 liters of air) when you are resting up to about 40-60 times a minute (100 liters of air) … WebLarge tidal volumes of 10-15 ml/kg may produce alveolar injury. Preferred tidal volume = 7-8 ml/kg; Remember that some volume is lost (due to compression) in the circuit (2-3 ml/cm H20). Ventilator Rate. On bedside chart, record both the rate set on the ventilator and the patient's total respiratory rate. IMV

Minute ventilation - Wikipedia

WebPreclinical studies indicate that isoflurane increases respiratory drive [7,8,9].Specifically, tidal volume and, thus, minute ventilation are better maintained with isoflurane than with propofol [].Consistently, patients sedated with isoflurane are more likely to breathe spontaneously than patients sedated with propofol despite moderate to deep sedation [].
