How does surfactant facilitates alveolar ventilation?


is it caused by the attraction of water to the alveolar surface

how does a pneumothorax affect lung volume and alveolar pressure when inspiratory muscles contract?


the ventilatory rate is abnormally high.. (tachypnea or hyperventillation) breath sounds are diminished of the affecte side, and they appear to be deprived of oxygen (agitated, hungry for air, disoreinted, poor skin color/ cyanosis) the lung volume will decrease, and the alveolar pressure will increase..  (+ info)

What is pulmonary alveolar proteinosis and lymphangioleiomyomatosis?


Pulmonary alveolar proteinosis is a rare condition and patients with this disease usually present with insidious dyspnoea that has progressed over months, sometimes with mild systemic symptoms such as low grade fever and weight loss.Usually, it has a benign course with eventual resolution. Rarely, rapid progression to respiratory failure is seen.
Death occurs due to progressive filling of alveoli or superimposed infection.

In the rare condition of lymphangioleiomyomatosis (LAM) a bizarre proliferation of smooth muscle cells (LAM cells) in the lung involves the smooth muscle of lymphatics, arteries, veins, bronchioles, and alveolar walls.
Dyspnea is the usual presenting symptom.The condition is characterized clinically by slowly progressive breathlessness and basal shadowing, and three distinctive complications: multiple pneumothoraces, haemoptyses and chylous effusions.Oophorectomy has produced good results. Treatment is by oestrogen antagonists or progestogens but the response is unpredictable and does not always correlate with the presence of oestrogen receptors.

What is the effect of emphysema on dead space in the lungs and what will this do to the alveolar ventilation?

What is the relationship of alveolar ventilation to PaO2 and PaCO2?


explain
----------

With a question at that level i would think you would know how to Google. :)

Can anyone tell me the best hospital and doctor to treat RHABDOMYOSARCOMA it is a cancer disease please help?


THANKS!! Any info would help?
----------

Not sure where you are located. In my opinion, Memorial Sloan Kettering Cancer Center is the best.

Why alveolar surface tension is reduced in emphysema?


Are you trying to cheat or just study for a test?  (+ info)

My newborn is infected "alveolar rupture complication"." pneumopericardium",the doctor said. How to treat it?


Please help me, urgent!!!
This complication arises when Respiratory Distress Syndrome treatment with surfactant
----------

Talk to your baby's doctor about treatment, or get another opinion from another doctor.  (+ info)

what is the relationship between Paco2 and alveolar ventilation?


An increase in aleveoolar ventilation can cause an decrease in Paco2 and a decrease in alveolar ventilation can cause an increase Paco2. An increase in Paco2 can cause an increase in alveolar ventilation and a decrease in PaCo2 can cause a decrease in alveolar ventilation. Anything such as a lung disease can cause alveolar ventilation to be not as adequate thus resulting in an increase in Paco2.  (+ info)

Where are the "intra-alveolar" and "intrapleural" spaces?


Where are the "intra-alveolar" and "intrapleural" spaces? Describe the pressure changes in these spaces during one respiratory cycle. Why does the lung collapse if intrapleural pressure is not maintained?
----------

Open your text book and read it. You will not learn if you don't have to do the work.  (+ info)
