minute ventilation

Exhalation is usually silent, except at high minute ventilation rates.

Second, physicians selected minute ventilation too low to allow for adequate rest of the respiratory muscles.

Hyperventilation is the term for having a minute ventilation higher than physiologically appropriate.

Advice to use air conditioners, to remain indoors, and to avoid increasing minute ventilation are appropriate.

Minute ventilation during moderate exercise may be between 40 and 60 litres per minute.

This is not to be confused with the term hyperpnea which pertains to an increased minute ventilation.

For each patient, tidal volume and respiratory rate were adjusted to maintain constant minute ventilation throughout the study.

Driving a bicycle increases minute ventilation by a factor of 2 to 4 depending on the level of exercise involved.

Normal minute ventilation is generally 5-8 liters of air per minute at rest for a 70 kg man.

Specifically, patients increase the minute ventilation by spontaneous breathing, rather than patient-initiated ventilator breaths.

Because children are outdoors more and have higher minute ventilation they are more susceptible to the dangers of air pollution.

Progesterone has noticeable effects on respiratory physiology, increasing minute ventilation by 40% in the first trimester.

Its performance depends on the minute volume of the patient: its output drops with increasing minute ventilation.

A low Pa indicates that at the patient's current minute ventilation (whether high or normal) is not enough to allow adequate oxygen diffusion into the blood.

Inadequate pulmonary minute ventilation (e.g., respiratory arrest or by drugs such as opiates)

Minute ventilation is equivalent to tidal volume multiplied by respiratory rate and is used to assess metabolic activity.

Thus, V T and minute ventilation delivered to the patients were kept constant for all concentrations of inhaled NO.

However, IMV differs from continuous mandatory ventilation in the way that the minute ventilation is increased.

If the calculation suggests the volume target will not be met, supplemental breaths are delivered at the targeted volume to achieve the desired minute ventilation.

V denotes the Minute ventilation of the lungs (the volume of air expired by the lungs in one minute).

Mandatory minute ventilation (MMV)

Transient improvement in oxygenation may have occurred because of increased minute ventilation secondary to alteration in tidal breathing pattern following aerosol administration without bronchodi-lation.

Mandatory minute ventilation is a volume control mode of ventilation and a derivative of intermittent mandatory ventilation.

The deficit will vary at constant depth with the ratio of respiratory minute ventilation to rate of oxygen consumption, as will occur in hyper- or hypoventilation.

The PaO2 is a function of the FiO2, the PEEP level, the mean airway pressure and the minute ventilation.
