Passed my NREMT first try yesterday and I did the entire Accelerator Course in Evan’s video vault. Worth every penny, worth all the hype. I’ll be back for paramedic school. Evan you are the man.
I’m sorry but this is not a good explanation of these modalities. CPAP is not forcing air in. It’s a continuous pressure throughout the cycle, but the benefit or function of CPAP is that it retards exhalation. It has nothing to do with the inspiratory cycle at all. In fluid overload, It assists reabsorption of fluid by maintaining a positive pressure during exhalation. In an asthma situation or other restrictive component, because it’s difficult for the patient to get the air out, it stents open the airways allowing for gas exchange. PEEP is the positive pressure at the end of exhalation during the cycle when an inspiratory pressure is used. So in BiPAP, the PEEP setting is the lower pressure setting of the two. So if you think of having CPAP on a patient and adding an inspiratory pressure that is higher, it then becomes an inspiratory pressure and expiratory pressure or PEEP. (Bi, or 2 pressures) As far as the inspiratory pressure, If you think of a toddler trying to climb up onto a couch, the inspiratory pressure is just a little pat on his bum to get him up there. It is a good assist if someone is having difficulty.
Thanks for clarity. Does CPAP have benefits in asthmatic patients and can it allow patient to exhale against continuous positive pressure? We had a discussion with my senior last week and he said they're no benefits of using CPAP in Asthmatic Patients
