  • I am in nursing school right now and I have an exam covering renal on Monday. Thanks for these lectures - they are really a big help. You have a knack for taking something complicated and making it understandable, but at the same time not leaving out any important information.

  • good clip but the long pauses are annoying.

  • Acute intrinsic renal failure

    This is also referred to as intrarenal failure and results from damage to structures

    within the kidney. Causes may be renal ischaemic, inflammatory, nephrotoxic

    or obstructive. Pre-renal ischaemia can cause intrarenal damage via the

    mechanism of acute tubular necrosis. John

  • what is intrinsic renal failure? is this drug abuse caused?

  • man u great

  • These are great for Student Nurses .. thanks

  • thank you for taking your time to help us..i thank you again...

  • i have this concern sir.. why does the specific gravity remains in normal range?... knowing that you have this acute renal failure?

  • Thankyou for the fabulous lectures-

    I'm very grateful.

  • Thanks for these videos. I wish part iii was availiable.

  • Unfortunatly youtube only give us 10 minute slots but you can order the full DVDs from my web site for covering costs,

  • If you did this study on an individual at least you would know yourself that what I have stated is correct. Yes of course I can produce the evidence because the claim is based on sound repeatable and factual results which become blatently obvious, particularly when your own fathers kidneys begin to function when My Brother and I were told that they would not recover! Not once but several times, each time when his bed was inclined!

  • Then why does the density of urine change when a bed is tilted to a five degree incline, either head down producing near water density and head up producing increased density? Test it for yourself or ask someone in the hospital to test the density of urine and posture relationship.

  • These claims have no evidence to support them, unless you are able to supply refrences based on empirical studies to support your claims they must be rejected. Urine density is not determined by body position,(in science we must belive the results of sound research and experimental studies so unless you have such evidence your claims must be rejected)

  • John

    I have challenged you to test the response to gravity by the urine density output of head up tilt, head down tilt and horizontal bedrest. Very easy to determine within one day for each test. You respond by saying it must be rejected? Why have you adopted this blanket response?

  • If you want to make a claim you must have evidence for it and you have not supplied me with any. If I did this study on an individual it woud not have validity. In order for a study to be valid it must reach a level of significance of p=0.5 or less. Can you produce such evidence, if not you should not make the calim,

  • @Campbellteaching Oh nooooo.. no more stats. My nursing student brain hurts.

  • Ok, let's put this in another way for the record. Dialysis requires gravity to drag the impurities out of the tubing into a tank containing presumably water. I propose that renal function is no different and requires the same gravitational pull in order for the solutes to be drawn from the kidneys under pressure and excreted via the bladder.

  • No, dialysis works by osmosis and diffusin through semi-pearmable membranes. Kidneys work by pressurised ultrafiltration followed by selective reabsorption. transpost of urine from the renal pelvis to the urinary bladder is by peristalsis of the ureter. These facts can be checked out if you read any physiology book,

  • The implications for avoiding flat bedrest are far reaching, for example, the circulation increases and more oxygen is distributed to the skin changing pale skin to a warmer tone. Body tmeperature no longer dips by 2 degrees at night around 4-5am, ironically the time when most people die in bed and the temerature drop is in existing literature. The heart rate decreases by 10-12 beats per minute and respiration rate by 3-4 breaths per minute when the bed is elevated by 15 cm's at the head end

  • I have my notes somewhere amongst a huge amount of paperwork as this was a long long time ago. The experiment was conducted to determine if my theory on circulation was correct or not. It might also interest you that varicose veins go flat in 4 weeks of inclined bed rest (IBT). The tension inside the veins increased due to the way gravity acts upon tiny pulses of solutes dragged through the vessels.

  • Its probably not a good idea to keep patients flat as they are much more likly to develop hypostatic bronchopneumonia,

    John

  • Great video, thank you for sharing it.

    Question. How do you account for sleeping on a 5 degree head down tilt producing near water density urine? Head up tilt of 5 degree producing marked increased density of urine over flat bed rest? Very easy to test. Can we talk? 01803524117

  • Who told you these strange myths about urine density??

    As far as I know positin makes no diference at all and ureteric function is peristaltic. Urine concentratin is controlled by homoestatic mechanisms such as the ADH mechanisn, not body position.

  • Hi John

    My wife and I conducted tests on urine density over a few weeks measuring changes and posture.

    Not a myth I am afraid John but a fact! and more to the point, with a simple hydrometer the experiments with posture and urine density are fully repeatable.

    In fact, my late Father had cancer and his kidneys failed 4 times, each time because the hospital staff failed to tilt his bed as advised. When they tilted the bed, his renal function was restored.

  • If true this is facinating, do you have any references relating to objective experimentation?

    John

  • What you should be asking is why my wife and I were testing urine density. This was because I have identified gravity as the driving force behind circulating fluids in the body.

    Evaporation, predominantly from the respiratory tract changes the density of the fluids at the lining of the lungs, sinuses, nasal cavity and throat.

  • My web site is campbellteaching dot co dot uk but it is not big enough to store videos. However you can buy the DVD for covering costs if you want your own copies.

  • I am very much impressed by ur videos and i would like to know ur website and so i can view ur videos from there it self.
