Question 1

with an av canal defect what is the normal?oxygen saturation levels in an infant?

Accepted Answer

Depends: Av canal defects are a cluster of seperate defects.  The oxygen saturation would depend on which defect is present and to what degree.

Question 2

what the level of oxygen can harm infant?

Accepted Answer

Depends: When giving oxygen therapy to an infant, the lowest level should be given to maintain saturation above 92%. Studies show that giving 50% oxygen for several days casues toxicity and using 100% for even several hours can have deleterious effects.

Question 3

if an infant's o2 levels get too low from something smothering - but re obtain oxygen again before going into arrest (needing cpr)- can they have permanent consequences? or would the infant not be able to come back after damaging state starts?

Accepted Answer

No uniform answer: Infants have a better ability than older kids or adults in tolerating such events. They are also variable in consequence by age of kid/duration of event/other co-morbidities. It is certainly something you want to avoid, but I have seen kids go through such events that seemed very bleek at the time grow into successful adults.

Question 4

explain the blindness from levels of high oxygen when given to a premature infant?

Accepted Answer

Oxygen free radicals: Oxygen in high concentrations cause oxygen to breakdown and form oxygen free radicals which can damage cells in the body.  In premature infants, this can lead to what is called retinopathy of prematurity.

Question 5

could sepsis cause oxygen saturation levels to fall?

Accepted Answer

Yes: Sepsis can cause acute lung injury (ali) and adult respiratory distress syndrome (ARDS) which are both reactions of the lung to the toxins and cytokines in the body and cause the alveoli to fill with inflammatory exudate thus preventing the exchange of gases and causing the oxygen saturations to fall.

Question 6

what finger are you actually supposed to check your oxygen level on? anytime i go to the dr theyre using the left i googled it and it says the right hand so wich hand and finger are correct?

Accepted Answer

: Any finger on either hand should have the same blood oxygen content. We occasionally look for different numbers in newborns as a sign of a heart defect. (Different flow to different sides with defect) That is not an issue for regular adults or older kids.

Question 7

my arterial blood gas says p02 is 72 and the oxygen saturation is 95 and calcium (ionised) 1.12 . are these normal numbers?

Accepted Answer

: Such numbers suggest the "ABG" was actually obtained from a vein, not the artery. A saturation of 95% would  correlate with an arterial blood gas above pAo2 94.

Question 8

currently on apap for mild sleep apnea. oxygen saturation 94%-98% most of the night with some dips to 90%. is 90% oxygen saturation considered hypoxic or normal during sleep? not sure if my treatment is adequate?

Accepted Answer

: The duration of the low oxygen saturation readings less than 92% may be assessed by a sleep study or overnight oxygen saturation study. if there are brief desaturations, usually there is no sequelae.
Watch for signs of excessive sleepiness during the day.

Question 9

is 5 minutes of oxygen level below 90% while sleeping every night bad for you? i suffer from sleep apnea? i wear continuous pulse oximeter every night?

Accepted Answer

: If it is 5 continuous minutes, that is more of an issue than if it is one minute at a time and it adds up to 5 minutes over the course of the night. If you are using CPAP or BiPAP, perhaps it needs to be adjusted if you are still having a pulse ox of less than 90% for 5 minutes at a time. Let your doctor know so that adjustments can be made if needed. Good luck!

Question 10

i have covid (3rd day) the weirdest thing happened to me... i was taking my decaf coffee now and suddenly i felt very weak, sweating profusely, dizzy, i went to my room where the a/c is and in 3 minutes it was gone. oxygen level 95 what was that?

Accepted Answer

: All these symptoms suggest one should revisit the PCP or go to Urgent Care or ER for appropriate evaluation and management.
