WebRationale: The rate is set to achieve appropriate minute ventilation, where minute ventilation = VT × respiratory rate. The rate setting depends on how ... Rationale: High- and low-pressure alarms, inspiratory time, and VT limits are always set, and the values are based on the cycling mechanism chosen. Low- Blood carbon dioxide (PaCO2) levels generally vary inversely with minute volume. For example, a person with increased minute volume (e.g. due to hyperventilation) should demonstrate a lower blood carbon dioxide level. The healthy human body will alter minute volume in an attempt to maintain physiologic homeostasis. A normal minute volume while resting is about 5–8 liters per minute in humans. Minute volume generally decreases when at rest, and increases with exercise…
