    COPD

    ...I'd suggest contacting Divers Alert Network to get individual advice. DAN published an article on it: https://dan.org/alert-diver/article/copd-incompatible-with-diving/ There has been a number of threads on this as well if you search the forums...

    COPD

    I became PADI scuba certified in 2023. Shortly after I was diagnosed as having COPD. I have not had no symptoms but was advised against scuba but told I could safely free dive. Is scuba an absolute no with a COPD diagnosis or can you dive with minimal risk of you stay shallow (30 feet)?

    Question Freediving and COPD

    Hi. I'm damnedsmith, and I'm new to freediving. Never done it in fact. I have COPD, which is a contraindication, but I see that some people have it and still freedive. Any thoughts or recommendations? Thank you in advance.

    Hello From an Oldtimer

    Man, that's great. What do you find to be your greatest challenge? I have COPD, so I'm most concerned about my lungs holding up. That said, I just returned from a local dive shop and bought some fins and booties. They said that, as a customer, I could come in and use their pool anytime I...

    Describe mental phases of static apnea (Beware, LONG post!)

    Would be awesome if you could check if the patients talked more of having strong headaches. And if so for how long? For how long did the chronicial condition last on average as the mentioned signs of hyposensitizing to CO2 occured? I remember effattah talking about the high chance of getting a...

    Describe mental phases of static apnea (Beware, LONG post!)

    I guess its a constant rising of the tollerance to a rise in paCO2, as COPD is a long term chronic condition. The patients do fight for breath, but that may well be due to low O2 aswell. I'm not an expert, only a medical student, if I can find out any more I will report back.

    Describe mental phases of static apnea (Beware, LONG post!)

    That's very interesting, EddieP. In the example of the COPD, does it develop gradually? If so, the paCO2 levels must be raising steadily from constant normal to constant high. Does it happen so gradually that the body ignores the change whatsoever, and that high CO2 levels cause no extreme...

    After Black out

    I wander, after the BO what would be the average time value until we talking CNS anoxia in a healthy adult without any history.If the study shows 6 min,many times we have people COPD with an spo2 value below 88% which are still talking and able for small physical activity...Any volunteers?

    Freediving after a Pneumothorax

    ...a pneumologist with specialisation in Diving Medecine. As Rik said the type of operation (VATS vs. open) and the physical constitution (Smoker/COPD) have a progostic impact. Medscape: "The 5-year recurrence rate is 28-32% for primary spontaneous pneumothorax (PSP) and 43% for secondary...

    CO2 tolerance

    ...of the neurons and that affect the respiratory drive. The best example is the people suffering of Chronic Obstructive Pulmonary Disease (COPD) they have a high level of CO2, so with the time the respiratory drive is triggered mainly by levels of O2. There is also an study with freedivers...

    Freediving on 36-40% O2

    ...in many different types of patients when using O2 (enriched air). But there was also some critic for some "traditions" in O2 limits concerning COPD-patients having CO2 retentio(=>hypercapnia): All about Oxygen (Maybe it interests those freedivers too who do too often huge packing (or who...

    Deeperblue is for real!

    ...prohibited me from partaking in any Rubustas , Churchills,or Partagas only having one Lung and being on 3 Liters of oxgen per nassal cannula for COPD tells me its time to clean my act up and to get in shape for Jons Freediveapooloza and see if I can hold by breath for 10 seconds excuse me now...

    Bet you cant answer this?

    I think you misunderstood my comment, GetawayFK. I did not speak about the residual lung volume. I was speaking about the gas exchange in lungs during a prolonged apnea and about O2 remaining in the air held by lungs (and not just in the residual volume). Quite oppositely I referred to the state...

    Bet you cant answer this?

    ...so that your lung doesn't collapse and the dead volume is the volume that air will occupy at any time in your respiratory system. Residual volume can greatly varie (e.g: in asthma or COPD it can occupies up to 60% of your functional volume) etc... I'll get to your question later. See ya

    Bet you cant answer this?

    ...can itself change due to different strains or exercise happening. A particular interesting finding is that I noticed in most smokers (with no COPD or other chest diseases), their level of Hb is on the average higher than non-smoker (normal values should be btw 12-16Hb although that can also...

    Why do you freedive?

    ...had a morbid fear of the water as a child, overcoming Acromegaly as an adult and am told everytime I have a chest x-ray that It shows I have COPD! Moral of the story: Don't tell me something can't be done because I will find a way to show that it can! Freediving has allowed me to show others...

    Hemoglobin levels and blue/purple lips

    ...in itself, but I was surprised at how dark the blood was and it made me wonder if my hobby was having an effect on my hemoglobin levels. I know that folks w/ diseases that reduce respiratory function (e.g. COPD) often develop elevated Hgb levels -- maybe amateur apneists do too. Nice post!
