Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels. It can be measured with devices such as a ...
Mandatory minute ventilation (MMV) (also called minimum minute ventilation) is a mode of mechanical ventilation which requires the operator to determine what the appropriate minute ventilation for the patient should be and the ventilator then monitors the patient's ability to generate this volume. If the calculation suggests the volume target ...
As our sleep deepens, our minute ventilation continues to decrease, reducing by 13% in the second NREM stage and by 15% in the third. For example, a study of 19 healthy adults revealed that the minute ventilation in NREM sleep was 7.18 liters/minute compared to 7.66 liters/minute when awake. [1]
Tidal volume increases by 30–40%, from 0.5 to 0.7 litres, [9] and minute ventilation by 30–40% [9] [10] giving an increase in pulmonary ventilation. This is necessary to meet the increased oxygen requirement of the body, which reaches 50 ml/min, 20 ml of which goes to reproductive tissues.
Mandatory minute ventilation is a mode which requires the operator to determine what the appropriate minute ventilation for the patient should be, and the ventilator then monitors the patient's ability to generate this volume every 7.5 seconds.
