ERV = volume of air that can be forcefully expired after a normal tidal expiration\n\nIRV = volume that can be forcefully inspired after a normal tidal inspiration\n\nVC = ERV + tidal volume + IRV = Total lung capacity minus residual volume, so D (vital capacity) is your correct answer

The answer is D. oxygen\n\n"Oxygen is given with a small amount of continuous positive airway pressure ("CPAP"), and intravenous fluids are administered to stabilize the blood sugar, blood salts, and blood pressure. If the baby's condition worsens, an endotracheal tube (breathing tube) is inserted into the trachea and intermittent breaths are given by a mechanical device."

Ventilation - the physical act of moving air in and out of the lungs.\n\na)  Passage way resistent would reduce the volume of air that could be inspired - either by hyperinflating the lungs thereby not allowing new air to fill the lungs with breathing OR by the simple resistence itself, no allowing air in (but its usually the former).\n\nb) Decrease lung compliance would reduce the inspiratory volume and therefore decrease ventilation.\n\nc)  If the lungs did not secrete surfactant, the surface tension of alveoli would be much higher and it would not be able to inflate normally.  Therefore ventilation would be reduced again.\n\nSo after I help you with your homework, are you going to buy me lunch?

asthma\n\nAddendum: in light of the second answer, I'll elaborate a little more.  Asthma is an obstructive pulmonary disorder.  The airway narrowing results--somewhat counterintuitively--in the patient having trouble getting air *out* of the lungs, resulting in air-trapping in the alveoli.  Clinically, patients have a prolonged expiratory phase.  The standard pulmonary function test is to measure how much air patients are able to exhale with a forced effort.  On X-ray, patients having an acute asthma attack will have hyperinflated lungs from the air-trapping.\n\nObviously, if you can't get the air out of the lungs, you won't have much capacity to inhale....

Vital capacity is the total amount of air that we can exhale forcefully. To calculate vital capacity, first you add your tidal volume and the extra amount of air beyond the tidal volume that your lungs can hold (the IRV). So, so far:\n\nVC = TV + IRV\n\nWhen you take the deepest breath you can and then exhale, you exhale first your IRV, and then your TV, but then you have even more air in your lungs that you can exhale if you need to. This is called the ERV. When you are measuring how much your lungs can exhale when they are FORCED to, ERV is part of the equation. So now:\n\nVC = TV + IRV + ERV\n\nThe reason you include ERV is because normally you don't exhale that amount of air (normally you will only exhale your tidal volume and, if you take a slight deep breath, some of your IRV). However, if you attempt to completely get all the air out of your lungs, you will also exhale your ERV. Since the definition, in general, of vital capacity is the total amount of air you can forcefully exhale, ERV must be a part of the equation.\n\nSide note: what is NEVER a part of the equation is residual capacity, RC. This is the amount of air in the lungs that you can't force out, no matter how hard you try. It is about 1 L.

I agree; c) is the right choice.  The other units are used to measure:\n\na)  power ratio\nb)  pressure\nd)  pressure (again)

The amount of air is the difference in volumes.\nA = V(r+1) - V(r) = (4/3)pi (r+1)^3 - (4/3)pi r^3\nA = (4/3)pi((r+1)^3 - r^3)

there is no such absolute number.\n\nDepends on the person, body size, lung capacity, and lung contractility
