What is a normal oxygen saturation levels in incubated patients with pectus excavatum?

What is a normal oxygen saturation levels in incubated patients with pectus excavatum?

Normal: I believe you are talking about newborns with a pectus who is on the ventilator. If this is the case, the saturation should be normal 99%, unless there is something else affecting the oxygenation level. ...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

I'm an oxygen dependent patient. I have o2 stats of 83 but all my tests are always normal. What can cause this?

I'm an oxygen dependent patient. I have o2 stats of 83 but all my tests are always normal. What can cause this?

Good morning . . .: I would presume that since you are on Oxygen, at such a young age, you must be seeing a specialist already. This sounds to me, to be a more complicated issue than what we can answer through this type of venue. Also, if you are checking your O2 sats at home, please be certain that it is working properly--maybe use it on family or friends who are not oxygen dependent. ...Read more

What are the minimum oxygen requirements for COPD patients?

What are the minimum oxygen requirements for COPD patients?

No minimum: There is no minimum. Ambient air is 21%, if it is not enough, you go up from there. Oxygen delivered by a nasal cannula starts with 0.5 lpm and goes up from there by half liter increments. Common starting rates are 1 – 1.5 lpm. ...Read more

Can they ever give the patient more oxygen than the lungs can hold?

Can they ever give the patient more oxygen than the lungs can hold?

Sort of: There are some patients with severe emphysema that have a drive to breathe based on oxygen rather than carbon dioxide. In these patients, giving too much oxygen can cause the person to stop breathing.

But, the lung will hold as much oxygen as it can physically hold. You can't really give it "too much.". ...Read more

Why is it so dangerous to give large amounts of oxygen to a patient with emphysema?

Why is it so dangerous to give large amounts of oxygen to a patient with emphysema?

Not usually: In the late stages of emphysema or copd, patients do not respond normally to stimuli that make normal patients breathe. They only keep breathing in response to low oxygen in their bloodstreams. If they are given too much oxygen, their systems think that they don't need to breathe and they can actually breathe less or stop breathing. This is a rare problem. Oxygen helps most emphysema patients. ...Read more

Will increasing a COPD patient's oxygen when taken to 5, 000 ft altitude injure her?

Will increasing a COPD patient's oxygen when taken to 5, 000 ft altitude injure her?

Usually not: Check with the doctor to make sure the patient does not have a tendency to retain carbon dioxide. Also, it is best to have an oximeter, a device that measures oxygen levels, with you. It will allow you to use just enough, not more not less. ...Read more

Drugs that inhibit cellular respiration? how do cells utilize oxygen and how do you counteract this side effect so patient doesn't die of hypoxia?

Drugs that inhibit cellular respiration? how do cells utilize oxygen and how do you counteract this side effect so patient doesn't die of hypoxia?

It is complex: Your questions are only relevant if you tell us why you are asking about such questions? Please tell us which drug/s you are taking or wanting to understand?. We can not deal with theoretical considerations such as you have posed. Life's physiology is quite complex. I had to study for 10+ years before I could understand questions like this! ...Read more

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low blood oxygen: At the advanced stages of copd, the lungs do not perform their function well, oxygen has a harder time crossing into the blood stream. At this point, the body is not getting enough energy, the blood oxygen level is low. Raising the amount of inhaled oxygen offsets the problem, and prolongs life. Oxygen is used at the lowest amount that would achieve the goal. ...Read more

Considering the heart need for oxygen, can exercise be helpful to both stable and unstable angina patient?

Considering the heart need for oxygen, can exercise be helpful to both stable and unstable angina patient?

exercise is medicine: The heart extracts the same amount of oxygen at rest or exercise. What the heart needs is more flow which is why blocked up arteries cause chest pain/heart attacks. One way to increase flow is to exercise to build up the bodies ability to recruit blood flow when needed. You should not exercise while you have unstable angina until it is controlled though. In stable angina exercise it great. ...Read more

Can oxygen therapy be used to prevent cough in bronchiectasis patients?

Can oxygen therapy be used to prevent cough in bronchiectasis patients?

No: Oxygen therapy is only used in patients with advanced bronchiectasis who have difficulty maintaining normal oxygen saturations. To prevent cough in patients with bronchiectasis, it is important to remove the excess mucus from the airways by use of mucolytic therapies (inhaled hypertonic saline) & physical techniques to mobilize the mucus (chest vest, acapella, flutter etc.). Talk to a lung doc. ...Read more

For what reason should patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

For what reason should patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low oxygen...: People with COPD can develop low oxygen levels due to their lung disease. Oxygen therapy is then administered in the lowest amount needed to treat their hypoxia. Too much oxygen can actually cause lung toxicity which worsens lung function. ...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!

How would oxygen therapy help a patient who is having an asthma attack? What effect will it have on the patient?

Prevention: The respiratory system has an important roll in both providing oxygen to tissues & helping acutely regulate the delicate acid base balance in the body. Bronchospasm reduces the easy transfer of oxygen in & co2 out of the body. Without adequate o2, the body reverts to a metabolism that creates more acid causing deterioration, supplemental o2 helps avoid the acid buildup & nourishes tissues. ...Read more

What changes can you expect in the levels of blood oxygen and carbon dioxide in a patient who breathes rapidly and deeply for a prolonged time?

What changes can you expect in the levels of blood oxygen and carbon dioxide in a patient who breathes rapidly and deeply for a prolonged time?

Hyperventilation: Many athletes may "oxygen-load" their blood just prior to a race by doing this. Breathing rapidly will draw in more oxygen and "load up" the red blood cells' hemoglobin, and at the same time empty out more carbon dioxide than usually would be. You have to be careful doing this, because it will throw off your body's acid/base balance and make you dizzy or pass out! ...Read more

Does increasing oxygen work if patient is in respiratory distress and if they have low hemoglobin?

It does. : It will help if the patient o2 saturation is low. You would like to see it between %96-100 by adjusting o2 flow of 1-2 lit per min. But the main goal should be raising the hemoglobin to normal level. ...Read more

What is the percentage of oxygen is needed by a congenital heart disease patient? This patient is 3 month old.

Above 80: If a cyanotic heart lesion cannot be repaired yet, saturations are acceptable over 80. Sometimes if there are no good options for surgery due to size or other risk factors, upper 70s are tolerated. In the usa most will have sats in the mid 80s before complete repair. ...Read more

Why does pure oxygen stop breathing when patient is in respiratory distress?

Why does pure oxygen stop breathing when patient is in respiratory distress?

Depends on situation: Part of the bodies mechanism for deciding when to breathe is controlled by co2 sensors in the main blood vessels. In some medical conditions (like copd), when excess oxygen is given to patients & drops the co2 level, their sensors stop the automatic breathing cycle until it builds back up. ...Read more
