What is arterial gas embolism in simple terms?

What is arterial gas embolism in simple terms?

Air Blockage: I'm assuming you mean an "air embolism." it's when air gets into an artery and the air bubble gets jammed up further down the line. At that point, blood can't get past the air; serious consequences or no consequences at all can result depending on where the blood flow blockage occurred. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Why coarctation of aorta in infants, causing blood flow from pulmonary artery to aorta?

Why coarctation of aorta in infants, causing blood flow from pulmonary artery to aorta?

PDA : It would only do that if the coarctation was severe and there was a patent ductus arteriosus (pda) which is a connecting artery between the aorta and pulmonary artery, leading to blood flow from pa to the descending aorta. ...Read more

What causes mesenteric arterial thrombosis?

What causes mesenteric arterial thrombosis?

3 major factors: Condition of the artery (caliber, plaque, injury, inflammation...) viscosity of the blood (hydration, tobacco, blood element derangement...) and the force of the blood flow (stasis, poor heart functions...) are the main factors leading to mesentary arterial thrombosis. It can happen in association to an embolic event. ...Read more

Which has higher co2, cord arterial blood gas or venous?

Which has higher co2, cord arterial blood gas or venous?

The non-red blood: in the cord I forget which one has the oxygen, but that has the good air and not the bad air. I'm pretty sure it works reasonably with arterial going IN with oxygen and nutrients and coming back out with wastes and CO2. ...Read more

Is it possible to develop a pulmonary embolism from a blood gas arterial draw?

Is it possible to develop a pulmonary embolism from a blood gas arterial draw?

No: A clot formed in the radial artery, the usual site of blood draw for arterial blood gases, does not have a way to reach the lungs. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Drink enough water daily so that your urine is mostly colorless. Practice safe sex. ...Read more

Could pulmonary embolisms return?

Could pulmonary embolisms return?

Yes: Newer guidelines from accp recommend long term blood thinning. Also the primary cause may be determined and this will increase your risk for them to return. Some patients require filter to be placed in the lower veins to prevent clot from reaching the lungs. Again risk factors must be determined. ...Read more

Why would keto-acidosis lead to decreased pco2 in arterial blood gases?

Why would keto-acidosis lead to decreased pco2 in arterial blood gases?

Compensation: In response to the low ph caused by the ketoacidosis, the brainstem triggers a dramatic increase in the respiratory rate. This causes the lungs to expel more carbon dioxide in a process known as respiratory compensation for metabolic acidosis. ...Read more

Please explain why is pulmonary arterial blood pressure less than systemic arterial blood pressure?

Please explain why is pulmonary arterial blood pressure less than systemic arterial blood pressure?

PAP: The resistance to flow of blood is much lower in the lung than in the systemic circulation, this is why the pa pressure is normally lower than systemic pressure, the blood flow in both circuits is normally the same and pressure equals flow times resistance. ...Read more

What does blood clot in the lungs (pulmonary embolus) show on ventilation perfusion scan?

What does blood clot in the lungs (pulmonary embolus) show on ventilation perfusion scan?

Lack of blood flow: A ventilation perfusion scan is a test for a blood clot in the lungs, or pulmonary embolism. If there is a blood clot, an area of the lung will not be perfused, but will be ventilated, and therefore a mismatch will be seen. ...Read more

Could inhalation of chlorine gas cause pulmonary edema?

Could inhalation of chlorine gas cause pulmonary edema?

Absolutely: Chlorine gas is extremely toxic to the lungs with inhalation and frequently fatal. It damages the fragile alveolar capillary membrane and causes fluid to leak into the air spaces. ...Read more

Pulmonary emboli or blood clots in the lung; deadly? Very dangerous?

Pulmonary emboli or blood clots in the lung; deadly?  Very dangerous?

Yes. : Pulmonary embolism is often fatal but it really depends on the size of the clot that travels to the lung. Small clots may not even be noticed but large ones completely stop lung circulation and exchange of oxygen resulting in rapid death. ...Read more

Can a low heart cause pulmonary embolism?

Can a low heart cause pulmonary embolism?

No: I'm guessing that you mean a heart that lays low in the chest. This would not cause pulmonary embolism; in fact the position of the heart would have no effect on pulmonary embolism, which is caused by clots in veins (usually in the legs or pelvis) breaking loose and traveling to the lung. ...Read more

What causes pulmonary embolism?

What causes pulmonary embolism?

Blood clot: A pulmonary embolism is the result of a blood clot travelling to your lungs. The blood clot (referred to usually as a DVT) is usually found in the veins in one or both of your legs. This breaks loose and travels up through the IVC to the heart and then to your lungs. ...Read more

How would oxygen deprivation change arterial blood gas levels?

How would oxygen deprivation change arterial blood gas levels?

Breath rate increase: O2 deprivation will typically cause people to breath faster. Abg measures levels of oxygen, carbon dioxide and blood ph. Faster breathing causes a drop in co2 which then causes the blood to have an increase in ph (towards basic, not acidic). Over time, the body would compensate for this ph change via acid retention by the kidney and although the co2 would remain low, the ph would approach normal. ...Read more

Will an oxygen tank help with pulmonary embolism?

Depends...: In severe pulmonary embolism, the oxygen level in the body may decrease to levels that require supplemental oxygen. Most of these patients would be hospitalized for their treatment and once the clot resolves, oxygen level should return to baseline levels. ...Read more

Could pulmonary embolism 'go away'?

Could pulmonary embolism 'go away'?

Yes....: A pulmonary embolism is a blood clot in the blood vessels in the lung. Symptoms range from no symptoms to death, depending in the size and location of the blood clot. Once the blood clot is no longer increasing in size, the body's own system will "heal" the clot by reabsorbing it. Blood thinners allow this to happen, by making it impossible for the blood clot to continue to increase in size. ...Read more
