Blood Oxygen Saturation level - what is the fatal and normal range? Blood Oxygen Saturation level - what is the fatal and normal range? How long is a sub 85% level sustainable without more than a simple mask? This is about my son. He is on hospice care, and is terminal. He is 1 year old, 9 pounds 8 ounces. This is a good weight for him due to proportion. He has a disease called rhizomelic chondrodysplasia punctata. He almost passed in july and barely beat an rsv infection that weakened him significantly. He is on a nasal cannula @ 1l. His oxygen sat level is now in in the high 80s with the 1l nasal cannula delivery. It drops to low 80s or worse at times when he cries or strains, or even urinates. Before these recent episodes he was in the low 90s with no oxygen. We have also put him on a feeding pump, which works with ng tube, to spread out his feeds and avoid fluid shock to his sytem. We will no hospitalize him. He was on oxygen only supplemental until 4 days ago when he had some respiratory episodes and needed to go back on oxygen permanently. I'm trying to get a realistic picture from someone who is no bias.

What is the normal blood oxygen saturation count in adults?

Blood Oxygen Saturation - Why does it decrease as you age? Assuming healthy diet and non smoker

Name and describe the current technological device that measures oxygen saturation in the blood?

What technologies allow the measurement of oxygen saturation and carbon dioxide concentrations in blood? Describe and explain the conditions in which these technologies are used.

why does the oxygen saturation in the blood only reach 97% and not 100%?

Select the correct statement about oxygen transport in blood:? 1) during normal activity, a molecule of hemoglobin returning to the lungs contains one molecule of O2 2) during conditions of acidosis, hemoglobin is able to carry oxygen more efficiently 3) increased BPG levels in the red blood cells enhance oxygen-carrying capacity 4) a 50% oxygen saturation level of blood returning to the lungs might indicate an activity level higher than normal

Can a low oxygen saturation cause chronic headaches? It is about 94% at 1,049 feet. Also my labs came back with elevated Red Blood Count. I have been a non smoker for over 15 years. I suffer from occasional episodes of atrial fibrillation.

describe how saturation (and rate of oxygen unloading) is affected by blood P02 levels, by blood pH, by temper

What do you cal this medical instrument? I was wondering what do you call the instrument that the nurse uses at the hospital, plastic thing that clamps your finger with a red light inside that checks your level of blood oxygen saturation

I have a question about the respiratory system could you help me? question 1: how does internal respiration differ from external respiration? question 2 outline the path of oxygen from the atmosphere to the bloodstream. question3 differentiate between oxygen transport and carbon dioxide transport in the blood stream. question 4 predict the effect that increasing altitude would have on a blood oxygen saturation. question 5 why does a single celled organism not need a respiratory system?

Asthma, oxygen saturation reading off? Also question about Xopenex (and nebulizer treatments in general).? Hi, I've been having some pretty bad asthma symptoms lately (bad enough where I went into the hospital last night). I was put on Prednisone 40 mg 2X daily. Anyway, my oxygen saturation was fine, and I'm wondering if my over-compensating breathing (i.e. I was trying to make up for my shallow breaths by taking more and taking them as deeply as possible, even though my chest was sore) would have highered it, when, if I had just let myself breathe without physically straining during the attack, it would have let my oxygen levels drop lower? There have also been times when I have a bad attack and my oxygen is close to normal, whereas a mild one is much lower. Could this be caused by my rapid breathing (in a desperate attempt to get more air in)? Lastly, can Xopenex nebulizer treatments cause high blood pressure temporarily (like 120/85)? I'm usually 90/60, but last night my BP was high. Thanks so much!

What is the normal saturation of Oxygen in newnates,and O2 SATURATION? amount of blood in neonates? THANKS

How do you know if doctors are doing enough for your child if there is so much information for them to review? My daughter's lung collapsed at birth and after three weeks was released from the NICU with no medications or machines. She was sounding very congested and her Dr. finally referred her to an ENT. That Dr. found that her adnoids were growing down into her throat which caused apnea. She is too young for surgery but her apnea monitor sounds often. A sleep study has confirmed that her saturation (blood oxygen) dropped below 70 % at times and put her on oxygen at home when she sleeps which is quite the challenge. Since then she has also been diagnosed with PDA and ASD Heart diseases; Anemia (even with iron suppliments); high platelet count; pulmonary hypertension. I'm at my witts end! I feel that I'm seeing all these different doctors and no one is putting the information together. They are all puzzled at how healthy she looks to have all of these things wrong. Is anyone in a simular situation or could shed some light on what could be going on? She is so precious. God bless!

Oxygen saturation levels drop while sleeping, what is this called? I do not have any interruptions in my breathing. No pauses, no snoring. However, my oxygen sat levels drop down to 80 soon as I fall asleep. This sounds similar to Sleep Apnea, but as I have no interruptions in breathing (no stops), it is not that. Anyone have an idea what the name of this might be? I am 24, Never smoked in my life. p.s. I am going back for second sleep study and all, but my doctor didn't give me any sort of name or idea of WHAT this could be, the cause of the lessened saturation during sleep, and wanted to have help to find more information before the second study so I am not as freaked out about this. Thank you all for the help. ~Also have type two diabetes, hypothyroidism, high blood pressure, year round allergies, and yes I am obese. (I have been trying to lose weight my whole life, please don't harp on it.) Thank you everyone again! I have been overweight my whole life, but the sleep issue is NEW. So it is not directly related to my weight. Thank you all.

Lack of Oxygen at birth, what is the likely outcome? (symptoms below)? My son was born by crash c-section 2 days ago. When he was born he had no heartbeat but had an apgar of 1 after 5mins then 6 after 10mins. When he left the theatre his heart rate was normal at 140bpm. He is on intensive care, but has been breathing for himself since day one, and all other obs (blood pressure, oxygen saturation etc are all normal) He has had two fits involving limb shaking and mouth movements as well as desat. They have mentioned cerebral irritation, and has had a 3rd dose of phenobarb today after the 2nd fit. After this he has slept peacefully most of the day. Can anyone suggest the likelyhood of a full recovery and possible future problems (I'm guessing his life is now safe) the doctors are very cautious and refuse to look past the day ahead. We live in the UK.

how does a FINGER OXIMETER work? i already went to howstuffworks.com but i need more detail, i already know that it takes blood-oxygen saturation (SpO2) level and pulse-rate, what i need is how the SENSORS inside work. thanks!

I have a very low oxygen saturation level. Lows around 70% to high of 88%. What are some possible causes? In the last four months, I've had a Ct scan, Hide-a-Scan, two heart studies, three halter monitors, sleep study,Sonogram, full body bone scan, endoscopy and complete blood work up. My cholesterol was slightly above normal. The sleep study showed I have sleep apnea. ( I now wear a C-Pap @ 17 psi w/ 5 lpm o2). The endoscopy showed some signs of mild damage due to aspirin and tylenol taken for the pain. The CT scan showed mild degeneration of L1 & L2 but otherwise nothing significant. (History of prostate cancer. Dr thought maybe the cancer had metastasized into the spine but bone scan showed no evidence of cancer) Moderate to severe pain in RUQ was diagnosed as costal condritis. Symptoms of this are improving. Bone chilling fatigue haunts me. I'm fairly certain that this is a direct result of the low o2 sats. Any ideas? So far, the doctors have not found out the problem. Thanks!

Please Help needed fast..? 1. predict the effect that increasing altitude would have on blood oxygen saturation 2. Arterial blood is about 98 percent saturated with oxygen. What are two conditions that could result in lower oxygen saturation? Please help.. Thank you so much

Do I have lung cancer? I do not have insurance and medicaid dropped me. A year ago they found a nodule in my lung. I had a few more scans and to my surprise it had grown. It is very small at 7 cm a year ago. At the last appt. they also said there were lymphnodes that were apparent. Now today I go to the ER for vomiting and they run blood work. Doc comes back and tells me I have low white blood count around 3. I am guessing 3,000. I also have a low oxygen/blood saturation. It was suppose to be in the high 90's and mine was between 70-85. I remember when I was in the hospital for surgery if it had dropped the gave me oxygen. I just do not know whats wrong. I am at a loss. I should mention I am only 28 yrs old

How do you find the amount of oxygen released to muscles in physiology? Assume that at rest the avg blood flow to the skeletal muscle is 100 ml/min with about 20 ml of oxygen per 100 ml of arterial blood (at sea level). What about at maximum exercise or at high elevation? How to calculate this isn't making any sense to me and I've found no help anywhere else. I know you need to use a hemoglobin oxygen saturation curve, but I'm not sure how to read it. Only helpful suggestions--no criticism, please!

Can someone help me with these bilogy questions? Describe 3 real life of any situations where the parameters like Hb-Oxygen saturation, carbon dioxide levels, pH, and myoglobin levels in blood are measured Will hyperventilation raise or lower blood pO2? blood pCO2? blood pH? Why? Will emphysema raise or lower blood pO2? blood pCO2? blood pH? Why?

Biology essay on red blood cell graph? I'm supposed to answer the following questions on this graph/subject, (I typed out everything it says.) and I dont understand it.. I'm homeschooled so I just cant ask a teacher and no one I know knows anything about it.. and I'm just so confused and stressed out (I get easily stressed, and then never shut up..) Red blood cells are able to transport oxygen throughout the body because oxygen binds to hemoglobin molecules within the blood cells. To learn how the concentration of oxygen in tissues affects the binding of oxygen to the hemoglobin molecule, researchers devised the following study. Samples of human blood were taken from various tissues. In each sample, the researchers measured the amount of dissolved oxygen in the tissue and isolated the hemoglobin. The amount of isolated hemoglobin was measured and then separated to determine how much of the hemoglobin had all of its binding sites filled with oxygen. The amount of saturate hemoglobin was compared with the total amount of hemoglobin to yield the percentage of hemoglobin saturation. Some results of the study are shown in the graph. Use the graph to answer the questions that follow. a. If the concentration of oxygen in the lung tissues is about 9%, what is the hemoglobin saturation of the red blood cells in the lungs? b. If the concentration of oxygen in a sample of body tissue is 4%, what is the hemoglobin saturation of the red blood cells in the sample? c. What happens to the hemoglobin saturation of the red blood cells as the cells move to tissues that have lower oxygen concentrations? d. What must happen to the oxygen bound to the hemoglobin as the red blood cells move to tissues with lower oxygen concentration?

Academic question part 2!!!!!!? BACKGROUND A 41-year-old man presents with fever, malaise, and a 20-lb weight loss over the past 3 months. The patient also has intermittent headaches, coughing with occasional hemoptysis, and multiple chronic skin lesions. The lesions initially appeared as hyperpigmented scaly plaques on his lower back (see Image 1). They have enlarged over the last year, spreading to his arms, nose (see Images 2-3), and penis (see Image 4). The lesions are not itchy or painful. Over the last few weeks, the lesions on the patient’s nose and penis have begun to ulcerate and produce a bloody, purulent discharge. The patient was diagnosed with HIV infection 13 years ago. He denies having any chest discomfort, shortness of breath, nausea, or diarrhea. He has not traveled recently and has not had any contact with people who were sick. He has not spent any time in environments where the risk of tuberculosis is high (eg, prison, shelters). On physical examination, the patient is afebrile with a blood pressure of 116/58 mm Hg and a heart rate of 92 bpm. His respiratory rate is 14 breaths/min, and his oxygen saturation while breathing room air is 96%. On his nose is a crusted, indurated plaque with irregular borders and central ulceration that produces thick, blood-tinged, suppurative discharge (see Image 3). A nontender oval-shaped crusted plaque with superficial ulceration is located on his penis at the base of the glans (see Image 4). Numerous skin-colored umbilicated papules, of about 3-6 mm and with central hemorrhagic crusts, are scattered irregularly on his arms and face (see Image 2). A diffuse, hyperpigmented lichenification of the skin is noted on his back, with many small areas of superficial ulceration (see Image 1). No retinal lesions are noted on funduscopic examination. No frank nuchal rigidity is present; however, the patient expresses moderate discomfort with neck flexion. The lungs are clear to auscultation with no rales, rhonchi, or wheezing; the cardiac examination is normal. The remainder of the physical examination yields unremarkable results. The patient is transferred to the adjoining emergency department (ED) and, because infectious meningitis is suspected, is placed in respiratory isolation. A lumbar puncture reveals an opening pressure of 22 cm H2O. A cerebrospinal fluid (CSF) sample is sent for laboratory evaluation and shows a WBC count of 450/mm33 (0.450 X 109/L) with a mononuclear predominance, a mildly elevated protein level, and a slightly decreased glucose concentration. India ink staining reveals the presence of fungi. What is the etiology of the patient’s symptoms? Are all of the lesions from the same disease process?

Can anyone advise me about best practice treatment options for a post operative pulmonary embolism? My husband is 48. He is a healthy, normal weight range, very fit non smoker . He had an arthroscopy with some unexpected other repair work done to his femur and knee cap on 22nd Dec.It was done under general anaesthetic which lasted less than four hours. It was a day stay procedure. He was given no asprin, no compression stockings and had no follow up appointment scheduled until 15th January. There was no referral letter to his GP. He was given codeine 60 mg every 6 hours as a pain reliever. He began coughing blood at 9 am 29th Dec and had spent a night with severe pain in his left side...which he didn't tell me about at the time!! He is being treated with Clexane and Warfarin subcutaneously. His oxygen saturation is being monitored. He will be in hospital for a minimum of 3 days. Is this the best course of action?
