my mom is in S.I.C.U. On the ventilater machine the O2 reads?

Question:

40 percent. On the machine that records your pulse and blood pressure says 100 percent oxygen. do you know how long she will be the trach ventilater?is this a good reading? RESPIRATORY THERAPIST please help

Answers:
The 40 you are referring to is the percent of supplemental oxygen she is receiving. The 100 is the oxygen saturation of her blood. 100 is obviously very good. Most doctors want this number at 92 or above. Sounds like her oxygen could be titrated down a bit. However, that is only one of many parameters that should be met before someone can be taken off of the vent. Have they performed a NIF on her? This is done by having a patient breathe through a small mouthpiece, and when instructed, they take in the biggest, deepest breath they possibly can, as fast as they can, while a small hole in the mouthpiece is covered so that they cannot inhale any air(it's kind of hard to explain in writing). This measures their respiratory muscle strength. Sometimes when people are on a vent, their muscles get lazy and it makes it harder for them to be taken off. It is very hard to answer your question with so little information. If you knew the set volumes, and your mom's spontaneous volumes it may be helpful. You can IM me if you have any additional information.

the decsion to wean her of ventilator is decded by the doctor himself & it involves many factors including the patients ability to breath on her own.
if the pulse oximeter read 40 & the pther read 100, then the 40 must be a wrong reading due to inproper attachment of the pulse oximeter & the finger nail.
i wish your mother quick recovery

As I told you before, we can not get much information from the blood gas reading you are telling us. As she is recieving supplemental oxygen from the vent. the reading will always be 100%. The point is: Can she breath on her own? If she can, how much Pa O2 she can reach without the machine oxygen. When she breath on her own and can get more than 60% Pa O2, she will be weaned off the vent. When this will happen, no one knows. Pray for her.
