Do you always know if you were having a pulmonary embolism?

No. Sometimes you have very small emboli that you may not notice or can be very subtle .
No. The smaller the clot(s) in number and/or size the less likely symptoms will be present. This has to do with how many and how large are the lung arteries blocked by the clots, which in turn determines the likelihood and type of symptoms.

How will having a pulmonary embolism affect my baby?

No direct effect. Pulmonary embolism (pe) is a potentially life threatening event that can occur as a result of a deep vein thrombosis (DVT) and DVT risk is increased by a factor of about 30 during pregnancy. Having a pe would not have a direct effect on your fetus, but fetal survival is dependent on maternal survival. Having a DVT and/or a pe will require anticoagulation, which can be done safely during pregnancy. Read more...
Hypoxia. If a pregnant mother has a pulmonary embolism it could lower her blood oxygen levels and then lower oxygen levels in the fetus. It is important to avoid/treat any hypoxia in a pregnant mom if it indeed is present. Read more...
Who has it. If you had pulmonary embolism (pe) while pregnant it could affect your baby development. The higher oxygen level is and shorter time of low oxygen in your blood is - it is less likely to affect your baby. Make sure you are on blood thinner ( heparin) and if necessary also on oxygen.

Hypoxia. If you are pregnant and developed pe( pulmonary embolism) then you can develop low oxygen(hypoxia) which can cause fetal damage in early stages for organ development or fetal death if severe hypoxia. Also you should be taking heparin/lovenox injections because they are safer than Coumadin (warfarin) on fetal effect. Read more...

Depends. The size and severity of the pe determine the long term effects. Small pes can be "relatively" well tolerated in that the child survives and does not develop long term problems. But large pes can be life threatening and lead to abnormal heart and lung function. Read more...

Marihuana embolism. Cannabis may increase the risk of bleeding in a the case of a 15-year-old with a cerebellar infarct that involved multiple arterial territories by martin et al 2000 causing a stroke.

After having a pulmonary embolism, is being short of breath normal when your INR is low?

Not really. You may be short of breath after pulmonary embolism (pe) due to residual clot in the pulmonary arteries if you get recurrent episodes of shortness of breath you may be having recurrent pe. This may occur especially if your inr is not maintained in the therapeutic range. This is not normal and requires further evaluation. Tell your physician! Read more...
Abnormal. But common due to, lung damage or heart impact inr is a test of anticoagulant - Coumadin (warfarin) and not specific to any breathing issue. Read more...

After having a pulmonary embolism, is it normal to be short of breath if your INR is low?

No. The concern would be that 1) shortness of breath is a common symptom of a pulmonary embolism and 2) a low inr means that the blood is not thin enough to protect against the formation of pulmonary embolisms so 3) the symptoms of shortness of breath might be a recurrence of a pulmonary embolus. Read more...
Depends. If you have had a large pe, it is normal to be short of breath for a few weeks or months as you recover, no matter what your INR is. If you have been ok with a therapeutic INR but now you are short of breath with a low inr, have yourself checked, or get some Lovenox or Arixtra shots while you are adjusting your Coumadin (warfarin) to a desired inr.

No. A low inr is dangerous if you have pulmonary emboli. You can develop new pe on top of the old pe's. So, i would try to keep the inr at a therapeutic level. Read more...
