positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.
Hi, you can update IFSC code in Bank Key using T.code FI02--->Control data--->Bank number and save.
I would love to know this answer too. Supposedly vertically positioned means 100% FiO2. But I can not find better info anywhere. This question is from Kettering home study workbook and their tutor service is terrible. So there is no one to help me out. I'm guessing if vertical is 100, then maybe horizontal is 21?
