Good explanation. I was quite confused about why CHF caused pulm edema. I also liked the tips about pretending your teaching someone else to reinforce the learning, as well as visualizing it on yourself. The ONLY thing I might suggest is adding the "chapters" to the video where different parts are discussed, but thats a minor point. Good teaching style, and good video.
It sounds like you found the explanation helpful and appreciated the teaching style of the video. Your feedback is valuable, and it's great to hear that you found the tips about teaching others and visualization useful. Thank you for your suggestion about adding chapters to the video for easier navigation; that's indeed a handy feature for viewers. It has been added and we hope this will helped new viewers!
Hello. Thank you so much for the nice and simple explanation with the nice pictures ! Deeply Appreciated !
Glad it was helpful!
Great lecture!
Glad it was helpful!
Awesome video, thank you
Many thanks! Watch the complete course on lectur.io/chfedema
This was great!
Many thanks! Watch the complete course on lectur.io/chfedema
Its my first experience to watched such a well explaination with diagrams and ideas!
Really thanks to the great job!!
Many thanks! Watch the complete course on lectur.io/chfedema
Great presentation!
Many thanks! Watch the complete course on lectur.io/chfedema
Thank you thank you so so so much 🥺😭 really I mean it mam coz I was getting mad like how fluid buildup really occurs as heart gives blood to the lungs after systolic action ..this video have cleared my doubt ( after watching 5-6 utube videos for clearing the concept 😂 but none told how ) n yes ur teaching technique is best. My bad u aren't my teacher in practical
I'm so glad it helped clear that up!
Best explanation !
Love this
Many thanks! Watch the complete course on lectur.io/chfedema
Amazing
Many thanks! Watch the complete course on lectur.io/chfedema
Hi, Could you please let us know the possible treatment for liquid formation in lungs and how long can a person survive with the heart failure and any control and managing techniques.
Awesome teaching! Thank you so much!
Glad it was helpful!
omg im going to owe you my nursing degree! this is awesome, thank you! 😅 So its blood in the alveoli?
Just fluid. In the blood vessels, you have red blood cells and plasma (plasma is 50% water and the rest is glucose, electrolytes, protein, etc). So, it’s everything in the blood vessel
We're very glad we could help. To clarify, pulmonary edema doesn't typically involve blood in the alveoli (tiny air sacs in the lungs). Instead, it's the accumulation of excess fluid in the lungs' interstitial spaces and air sac walls. This fluid buildup can make it challenging for oxygen to move from the air sacs into the bloodstream, causing breathing difficulties and other symptoms. If you have more questions or need further clarification, please feel free to ask. Good luck with your nursing degree and don't forget Lecturio Nursing can be your best study buddy - Start Your Free Trial Now! 😊
Thank you, my sister died at 57 from pulmonary edema due to chf 10 hours after a 1 hour plane flight. I believe high altitudes can cause this can you explain how please ?
I'm very sorry to hear about the loss of your sister. Pulmonary edema due to congestive heart failure (CHF) can indeed be triggered or exacerbated by factors like changes in altitude, such as during a plane flight. Here's an explanation of how this can happen: In congestive heart failure (CHF), the heart struggles to pump blood effectively. Traveling to higher altitudes with lower oxygen levels can strain the heart even more. This can worsen fluid buildup in the lungs, leading to pulmonary edema. The heart's increased workload and fluid redistribution can exacerbate CHF symptoms at higher altitudes. It's crucial for CHF patients to consult their healthcare providers before flying and follow recommended precautions to minimize risks.
Can you go over why CHF causes second spacing? I’m assuming because the kidneys aren’t being perfused well from the failing heart and in return, they can’t excrete as much fluid. The fluid then collects in the blood vessels and leaks out from hydrostatic pressure or oncolic pressure. Not sure which.
You're on the right track! Congestive Heart Failure (CHF) can lead to the phenomenon known as "second spacing," which involves the accumulation of excess fluid in the interstitial spaces between cells and tissues. Here's how it happens:
1. Reduced Cardiac Output: In CHF, the heart's ability to pump blood effectively is compromised. As a result, the cardiac output, or the amount of blood the heart pumps per minute, is reduced.
2. Kidney Perfusion: The kidneys play a crucial role in regulating fluid balance in the body. In CHF, the reduced cardiac output means that the kidneys may receive less blood and oxygen (reduced perfusion). This can impact the kidneys' ability to filter and excrete excess fluid effectively.
3. Activation of Renin-Angiotensin-Aldosterone System (RAAS): To compensate for reduced kidney perfusion, the body may activate the RAAS. This system helps retain sodium and water to increase blood volume and maintain blood pressure. However, this also leads to increased fluid retention in the bloodstream.
4. Fluid Accumulation: The increased blood volume, coupled with the heart's reduced pumping efficiency, can cause fluid to accumulate in the blood vessels. This is where the concept of "second spacing" comes into play. Excess fluid builds up in the intravascular (within blood vessels) space.
5. Hydrostatic Pressure: As more fluid accumulates in the blood vessels, it exerts hydrostatic pressure, which can force fluid out of the blood vessels and into the surrounding interstitial spaces. This fluid can accumulate in tissues throughout the body, leading to edema (swelling).
6. Osmotic Pressure: Additionally, the retained sodium and other solutes in the blood can increase osmotic pressure within the blood vessels, further drawing fluid out of tissues and into the bloodstream.
So, in summary, you are correct that CHF can lead to second spacing due to reduced kidney perfusion, activation of the RAAS, and the subsequent accumulation of excess fluid in the intravascular space. This excess fluid can then exert hydrostatic pressure, forcing it into the interstitial spaces and causing edema.
@@lecturionursing beautiful explanation! Thank you!
I was wondering why people with chf and swelling need their urine collected when on water tablets? Is it to measure output or see if theres someting going on with kidneys? Thank you
Collecting urine from individuals with CHF and swelling while they are on water tablets serves multiple purposes. Firstly, it helps measure the patient's urine output, which is crucial in monitoring their response to the diuretic (water tablet) treatment. It allows healthcare providers to assess whether the medication is effectively reducing fluid retention.
Secondly, monitoring urine output can provide insights into the patient's kidney function. In CHF, the kidneys may not function optimally due to reduced blood flow. Tracking urine output can help healthcare professionals assess whether the kidneys are adequately clearing excess fluid and waste from the body.
So, in essence, it serves both as a measure of the diuretic's effectiveness and as an indicator of kidney function, helping ensure the patient's overall health and response to treatment.
Thank you so much for the explanation :) @@lecturionursing
🙌
I’m not going to be able to get a finger on it because I can’t see it if it’s on the computer
Lol
Ahah that's the intention that counts, many thanks!
a self-fulfilling prophecy... positive feedback mechanism, only this time, it's trying to kill you
It's the truth! Good, and morbid way to think about it
