What oxygen level is required for normal breathing in a child?

What oxygen level is required for normal breathing in a child?

Depends on age...: Pulse oximetry is a standard mechanism to determine fairly accurately (most of the time) the oxygen saturation of the blood. The desirable saturation level varies based on infant/child age and multiple other considerations such as chronic lung disease, heart defects, body temperature, etc. However, for most children most of the time, we prefer seeing the level in the mid to upper 90's. ...Read more

Oxygen (Definition)

Oxygen is a gas that the cells in your body need to work properly. The air we breathe normally has 21% oxygen. A maximum of 100% oxygen can be given. Babies with heart or lung problems may need ...Read more

My neighbor says nattokinase and serrapeptase makes him feel like not enough oxygen reaches his brain. Normal breathing, though. Why is this?

My neighbor says nattokinase and serrapeptase makes him feel like not enough oxygen reaches his brain. Normal breathing, though. Why is this?

Enzymes: Nattokinase, derived from fermented soybean paste (natto), is eaten in japan. It has anti-coagulant effects and is said to be effective in amyloid forming tissues, but unproven for human disease. Serrapeptase is from serratia sp e-15 and said to have anti-inflammatory effects. Why is your neighbor taking either of these unproven substances. Have no idea why they would produce the effect he claims. ...Read more

Sudden onset of bony hard bulge between shoulder blades, at level T1, with pain radiating towards chest upon pressing only. Normal breathing. Dx?

Doubt cancer but...: If you have a new mass on the spine then you would need an MRI because it's likely something that could be cancer. However, cancers don't commonly arise there and nor are they painful so I would say it's less likely that and more likely some sort of spasm. ...Read more

What are the best breathing exercises for chronic hyperventilation syndrome? I need to restore normal co2 and o2 levels in my lungs. It's very hard.

What are the best breathing exercises for chronic hyperventilation syndrome? I need to restore normal co2 and o2 levels in my lungs. It's very hard.

Earlier answer: Treat the anxiety problem to decrease hyperventilation and do frequent rebreathing in a paper bag like a lunch bag to increase co2. The only other way would be to increase the precursor of co2 which is bicarbonate (sodium bicarbonate) by taking calcium carbonate (tums) or acetate. ...Read more

I get a airy, flutter feeling in my chest & when I do my oxygen level drops to 85 or lower and have hard time breathing. Can happen awake or wake me up?

O2 drop: If you are really getting a read of 85 I recommend you see an MD to confirm this and begin a workup of cardiac and pulmonary status. ...Read more

I'm pregnant and I'm having trouble breathing/getting enough oxygen. Is this normal? I there anything I can do?

I'm pregnant and I'm having trouble breathing/getting enough oxygen. Is this normal? I there anything I can do?

Sustained shortness of breath requires medical attantion: In normal pregnancy, accumulation of co2 stimulates the over-sensitive respiratory center in medulla oblogata resulting in episodic feeling of shortness of breath. Sustained sob however, may be related to a pathology in lungs, heart, or brain. ...Read more

Is it normal for oxygen saturation to sharply drop when deep breathing/hyperventilation stops? Patient's SPO2 can drop into 80% region

Is it normal for oxygen saturation to sharply drop when deep breathing/hyperventilation stops? Patient's SPO2 can drop into 80% region

YES: Hyperventilation raises PO-2 in normla lungs and afterwards the patient will UNDERBREATHE since the stimulation for breathing (Co2) has DROPPED due to the reapid breathing! To drop to 80% is completely normal (In my opinion)

Hope this helps!

My blood pressure is 111 over 59 and my pulse is 92. I have laboured breathing and my oxygen level last week was 85 - should I be concerned?

Yes: The blood pressure is good. The pulse is rather fast. The oxygen level if acurrate is quite low. You probably have some condition already that you are aware of since most people have no idea what their oxygen level is. Please get rechcecked by your doctor. ...Read more

Reason for follow up: The abdomen expands, pressing on the diaphram and giving feeling of not being able to take a full breath. If someone's got lung disease this can be bad; mostly just feels bad.
Pregnancy increases strain on the heart.
And, a huge number of (generally OBVIOUS) serious conditions can cause symptoms of strain on the heart and lungs. These are what are (always) screened for in (every) obstetrical visit ...Read more

Hi why when checking my blood pressure breathing from nose its. Normal but breathing from mouth its much higher. Oxygen 98 overweight 50 pounds?

Hi why when checking my blood pressure breathing from nose its. Normal but breathing from mouth its much higher. Oxygen 98 overweight 50 pounds?

Discrepancy: Breathing from the mouth shouldn't elevate the blood pressure unless you're straining while taking it. Nose breathing is more natural, also. You should regard your baseline BP as the one taken while you are relaxed in a sitting position with your arm in a neutral position roughly at the level of your heart. The BP should be just about equal in both arms. You can lower your baseline BP by losing wt. ...Read more

Arterial blood gas showed my pO2 was HIGH at 103. How is this possible? I'm not on oxygen therapy or anything like that. I was breathing normally.

Arterial blood gas showed my pO2 was HIGH at 103. How is this possible? I'm not on oxygen therapy or anything like that. I was breathing normally.

High PO2 level: It is important to know the rest of the blood gas test results. PH? pCO2? Bicarbonate? Your doctor can put it all in perspective for you. What was the O2 sat? If low, it might point to a methemoglobinemia, perhaps from some meds you take. Best to discuss the entire blood gas study with your provider. Normal PO2 shouldn't be above 102.. ...Read more

What is normal breathing rate after walking about 10 min and also after running?

NO such list: Your question is so ambiguous and out of context that it is impossible. There are dozens of variables and any breathing rate will vary from day to day within a range of normal. If you are not able to speak in a full sentence then you are working too hard at whatever activity you are doing. ...Read more

Is asthma curable? I am having light asthma since 22 years. Now I take forcart 100 mg daily which helps to keep normal breathing. How to reduce it?

Is asthma curable? I am having light asthma since 22 years. Now I take forcart 100 mg daily which helps to keep normal breathing. How to reduce it?

No: In general, asthma after age 7 years will likely be a life-long problem although the symptoms may fluctuate from time to time. I presume forcart is a drug purchased outside of the us and that it is an inhaled steroid. You should only reduce it under a physician's supervision guided by your history, the physical exam findings, and lung function test. ...Read more

After being diagnosed with a large saddle embolism I think IV now caught a cold & just my normal breathing seems restricted cud this be serious?

Pulmonary embolus: Your lung function may be compromised from your pulmonary embolus. The added insult of a pulmonary infection on top of your pulmonary embolus may be further impairing your respiratory status. I'd call your doctor right away. ...Read more

For 4 days I have had a dry cough with a heavy feeling in my chest and a constant need to cough feels like my chest is full of mucus. Normal breathing?

Dry cough: This may be a viral upper respiratory tract infection involving the trachea (windpipe). If your home is too dry, get a humidifier, drink liquids, and try an expectorant cough syrup to try to loosen secretions. See a physician if symptoms persist, or if fever, breathlessness, chest pain, wheezing develop. ...Read more

When I FULLY exhale the VERY last bit of breath sounds wheezy and I feel the urge to cough. Normal breathing ok?

No: Since asthmatic wheezing is the air getting caught in the airways at the end of expiration, it sounds as you are having air trapping in the bronchioles. See your doctor, to do an exam, pulmonary function testing and possb=ibly treat. ...Read more
