Pulmonary ventilation is the volume air that is breathed in or out in a single minute. It is the sum of the tidal volume (volume of air per breath) and the ventilation rate (the number of breaths per minute). For an individual's pulmonary ventilation to increase, there must be an increase in at least one of these two values. The individual can begin breathing deeper at the same rate (increasing tidal volume) or the individual can begin breathing faster at the same volume (increase ventilation rate) or both.

Minute ventilation represents the sum ofexhaled tidal volumes over a period of one minute. VE = VT x f; where VE is minute ventilation (the V should have a dot over it), VT is tidal volume, and f is frequency (respiratory rate).On Google Books check out "Pulmonary Function Testing and Cardiopulmonary Stress Testing," by Vincent C. Madama, page 86, 196, and 300-301: http://books.google.com/books?id=WDSVGYUc7FIC&printsec=frontcover&dq=Pulmonary+Function+Testing+and+Cardiopulmonary+Stress+Testing#v=onepage&q=&f=false
Treatment includes: placing the patient in a sitting position, oxygen, assisted or mechanical ventilation (in some cases), and drug therapy.
Chronic pulmonary diseases (most likely restrictive, but could also be constrictive), inadequate surefactant production, pulmonary edema, thoracic trauma (think fractured ribs). The list goes on.

Pulmonary ventilation.
Pulmonary ventilation ( breathing) is the physical movement of air into & out of the rspiratory tract.breathing
Pulmonary Ventilation consists of inspiration/inhaling, and expiration/exhaling
Pulmonary Ventilation(dmcubed/min) = Tidal Volume (dmcubed) X Ventilation Rate (min)
how does asthma effect pulmonary ventilation

Pulmonary Ventilation = Tidal volume X ventilation rate Simply rearrange the equation to find tidal volume Tidal volume = Pulmonary ventilation / ventilation rate Pulmonary ventilation is the volume of air moved into the lungs in one minute Tidal volume is the volume of air breathed in in one breath whilst at rest Ventilation rate is the number of breaths taken in one minute

Newborns with patent ductus arteriosis, a handicap affecting the pulmonary artery, are more likely to suffer pulmonary hemorrhage from mechanical ventilation.
Pulmonary ventilation occurs as a person inhales and exhales air and air is exchanged between the atmosphere and the alveoli of the lungs. During this, the pulmonary capillary blood gains oxygen and loses carbon dioxide.
