Hi, so ... I'm a mechanic, I work in aviation, and I deal with nitrogen quite a lot. It turns out that nitrogen is useful in tires, the nitrogen molecule is larger so it doesn't leak through the pores in the rubber as easily, so tires lose less pressure over time. Nitrogen in tires causes a lower fluctuation in pressure in regards to temperature. The machines that pull nitrogen from the air also removes condensation and therein prevents corrosion of wheels and tires, no air inside the rubber prevents oxidation of the rubber, When nitrogen is used in car tires the nitrogen is replaced several times to ensure that its up to 95% pure. We use nitrogen in every aircraft tire. Thank you for the video, was just a little bit i thought you might enjoy.

This is definitely facility, unit, and/or state dependent. I’m an ICU nurse here in the US and I’ve been able to stick for my ABGs quite routinely (along w/ RTs, attendings, residents). The consensus seem to be that if you’re a nurse/doc in a critical/emergency role...then it means you can be trained to draw them (I’ve also been trained to use iStat as a point of care gas analysis). 🤷🏽‍♀️

Hi Thank you for your video! I have a question about something that is been confusing me so much and I haven’t found an answer to, when you say PaO2 in blood is that in the gaseous state or liquid state( dissolved)? If dissolved then how come it’s 100 mmHg and the solubility of oxygen is only 0.003? Also I read that the partial pressure of oxygen in plasma is equal to the dissolved and undissolved oxygen does that mean (100mmhg of oxygen + 100mmhg*0.003)? Thank you very much in advance.

@chad1405 3 года назад

As far as I understand, we say SpO2 when we use non-invasive methods of haemoglobin saturation methods (pulse oximetry) and we use SaO2 with invasive methods (I guess, ABG and similar stuff). I would guess that SaO2 is a bit more accurate but I see these things being used interchangeably.

@anushreejagtap6163 3 года назад

SaO2 is the same thing as O2Sat. SaO2 is measured when arterial blood is drawn whereas O2Sat is measured using a pulse oximeter so it's not as accurate. Sp02 is the same thing as O2Sat - they're interchangeable :)

@brandiehenson6809 5 лет назад

To confirm anything you would need more tests . If his oxgen sat 02 is low and his pa 02 is high there could be a few things wrong. It could be a sign of infection, heart condition like a heart mermor,medication reaction allergic, flu ,really many thing there is not a perfect diagnose without more test for a real patient . You would need allergy checklist ,vitals, urine check for high protein ,blood panels for lab anisyise ...

Hello dr. Thanks for the video. I have a question about “the shifters”: so if i were to go to a place known for its high temperature, & i get a pulse oximetry test, will my oxygen content be theoretically less than 97% (since there is an increased ‘giving of o2, so less would be in the blood)??

@johnstewart8849 4 года назад

So, if I use an oxygen concentrator to get to 30% inhaled oxygen, I would be shifting the curve to the right? Are there any risks? I’m thinking more oxygen to brain, heart, lungs is a GOOD thing, no??

I have a doubt, Hb saturation means how much percentage of hb is bound to oxygen. Or How many 02 molecules are bound to one hb. Which one is correct? And if later one, then how 97.5% saturation is possible? Because one hb can bind only 1,2,3,4,5,6,7,8 oxygen atoms

In anemia there is low hb concentration in blood but there is no change in functioning of that hb which means their O2 Saturday will be normal theoretically. So it shows normal spo2. But actual oxygen carrying capacity of blood decreased

Hi... Can anyone explain why hemoglobin concentration is considered in O2 content when already SaO2 is there? (Isn't SaO2 = O2 on Hb??)

@MedicosisPerfectionalis Год назад

To insure that passengers are being transported to their destination, you need to take into consideration: a. the number of taxi cabs available (Hemoglobin concentration or Hb), and b. The occupancy of each taxi cab, meaning whether each car is fully occupied or not (Hemoglobin saturation or SaO2). Having good saturation per car, but less total card available means that less passengers overall will make it to their destination (i.e. anemia).

@unniroshan Год назад

@nathantjenkins93 4 года назад

does hematocrit percentage determine the oxygen carrying capacity? or is it the hemoglobin itself?

@MedicosisPerfectionalis 4 года назад

The hemoglobin itself. But, please remember that when the patient has anemia, RBC count, hemoglobin concentratio, and hematocrit may all be decreased. So, there are many factors at play

@nathantjenkins93 4 года назад

Medicosis Perfectionalis so the amount of RBCs wouldn’t contribute to the capacity of carried oxygen? And I understand, this is just something that has confused me for so long.

@MedicosisPerfectionalis 4 года назад

What contributes to the oxygen carrying capacity is: RBC mass (Hgb, Hct, RBC count) and Hemoglobin saturation. All these things need to be normal for an optimum oxygen carrying capacity.
