How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does positive pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
Why the boiling point of a pure liquid is usually reported along with the pressure at which the boiling point was measured?
Because the pressure could affect the temperature at which the water boils

How does alternating current and direct current affect heating ventilation and airconditioning?
how dose alternating current and direct current affect heating, ventilation, and air conditioning
What are the factors that influence your vital capacity?
Factors which may affect tidal volume and therefore overall minute ventilation during invasive ventilation include: lung compliance and resistance, Correct ETT/ tracheostomy positioning, adequate cuff pressure, ventilator settings ( eg. Is the pt in a controlled or spontaneous mode of ventilation, the level of pressure support dialed up etc), the patients conscious state and the patency of the ETT/tracheostomy tube.
Are there any shortcomings with volume as a measurement?
You should also include the temperature and pressure when the measurement is taken because these affect the sample measured.
Does temperature affect ventilation rate?
if its humid you cant breathe
Does hyperventilation affect spo2 readings?
It shouldn't. It is helpful to think of ventilation and oxygenation as separate processes. Ventilation (affected by respiratory rate and tidal volume) primarily affects carbon dioxide exchange, so hyperventilation will cause you to blow off more CO2 and therefore drop your partial pressure of carbon dioxide in the blood, resulting in a respiratory alkalosis. Oxygenation, on the other hand, is affected primarily by oxygen concerntration in the inspired air and pressure in the airways. Hyperventilation should not affect either, and so it should not affect your oxygen level.
How does increased ventilation rate affect arterial blood?
It will induce a respiratory alkalosis, as carbon dioxide is washed out of the blood by the increased ventilation rate.
How does ventilation affect plant growth?
Plants normally breathe in oxygen at night and carbon dioxide during the day. Without proper ventilation, plants will not get the right amount of both gases and this may affect their growth.
How does the temperature affect pressure measured in inch's of water?
Only by virtue of the change in density of water. As water expands with temperature rising its density falls slightly so the height of water for a given pressure will increase slightly.
