In manual ventilation you can increase the PaO2 by hyperventilating the patient, by increasing the respiratory rate and/or by increasing the volume of air that you deliver to the patient. If using a BVM for example, compressing the bag faster and/or harder will increase the arterial oxygen pressure, but there is a limit to what you can do with manual ventilation. Perfusion in the lungs has a major impact on PaO2. Also, the blood chenistry (anemia or CO2 poisoning) for example will dramatically decrease the PaO2. Sometimes no matter how much you hyperventilate the person, low PaO2 can't be corrected.

∙ 9y agoTo improve PaO2 with mechanical ventilation, the mean airway pressure must be increased. This can be done by lengthening the inspiratory time, increase PEEP, or increase Peak inspiratory pressure.

What are some reasons for not using mechanical ventilation?
Use of mechanical ventilation will be carefully weighed against benefit and possible risks. Some patients will require sedation to prevent fighting of the ventilator, which can increase the risk of complications.
What is the definition of mechanical ventilation?
Mechanical ventilation is the use of a mechanical device (machine) to inflate and deflate the lungs.
Inboard boats after July 31st 1980 have what type of ventilation?
They have mechanical ventilation.
When is mechanical ventilation ordered?
Mechanical ventilation is ordered for patients in acute respiratory distress, and is often used in an intensive care situation. In some cases, mechanical ventilation is a final attempt to continue the breathing function in a patient.Mechanical ventilation may be required only at night, during limited daytime hours, or around the clock, depending on the patient's condition. Some patients require mechanical ventilation only for a short period,
In COPD the PaCO2 will increase but the ventilation will not increase why?
ecause of air trapping and ineffective alveolar ventilation
What is passive ventillation?
Passive ventilation is a system of ventilation which requires no mechanical parts. for example, one could ventilate a room using a powerful exhaust fan, and that would be mechanical ventilation. Or one could simply open a couple of window's that would be passive ventilation.
What infants could be injured by mechanical ventilation?
Newborns with patent ductus arteriosis, a handicap affecting the pulmonary artery, are more likely to suffer pulmonary hemorrhage from mechanical ventilation.
Inboard gasoline boats build after July 31st 1980 must have what type of ventilation system?
Mechanical Ventilation System
Hypercapnia causes minute ventilation to?
increase as the minute ventilation is the amount of carbon dioxide
Inboard gasoline boats built after 1981 must have what ventilation?
mechanical
What is the formula for AA gradient?
PAO2 - PaO2 ****************************************** PAO2 is the Alveolar Air Equation: PAO2 = FiO2 (Pb- Ph20) - PACO2/R Notes: Pb = 760 mmHg Ph20 = 47 mmHg R = 0.8
