Simply translating to the amount of carbon dioxide (CO2) exchanged for oxygen (O2). The second half of the equation is representative of the fractional amount of dead space. This inspired air is assumed to contain a relatively zero amount of carbon dioxide. The equation states VD is equal to VT multiplied by the partial pressure of arterial carbon dioxide (PaCO2) minus partial pressure of expired carbon dioxide (PeCO2) divided by PaCO2.īreaking down this equation, there is the tidal volume which is the normal amount of inspired and expired gas equivalent to 500 mL. Understanding the equation will simplify the concept of dead space greatly. The Bohr equation can be used to calculate the amount of dead space in a lung. One can see an increase in the value of physiologic dead space in lung disease states where the diffusion membrane of alveoli does not function properly or when there are ventilation/perfusion mismatch defects. Therefore, physiologic dead space is equivalent to anatomical. In a healthy adult, alveolar dead space can be considered negligible. The respiratory zone is comprised of respiratory bronchioles, alveolar duct, alveolar sac, and alveoli.
DEAD SPACE 2 ENDING PLUS
Physiologic or total dead space is equal to anatomic plus alveolar dead space which is the volume of air in the respiratory zone that does not take part in gas exchange. This volume is considered to be 30% of normal tidal volume (500 mL) therefore, the value of anatomic dead space is 150 mL. Anatomical dead space is represented by the volume of air that fills the conducting zone of respiration made up by the nose, trachea, and bronchi. The two types of dead space are anatomical dead space and physiologic dead space.

(You know, I was wondering where Butters has been!) But it isn’t until we see the name tag on his door that we realize it isn’t Victor “Chaws.” It’s Victor Chaos. The episode ends with a return to South Park Mental Asylum Plus, where Kenny’s right-hand man “Victor Chaws” is being held. The pandemic was a test, and they failed. “Let’s face it, guys, we killed Kenny,” they deduce after reflecting on how they lost their sense of fun and sense of humor. A video on the flash drive reveals that not only was Kenny attempting to travel back in time to prevent the pandemic from happening, but he also blames the collapse of society on his “three d–khead friends, Stan, Kyle and Cartman.” He claims they “ruined everything when they let COVID break up their friendship and become argumentative, combative, pessimistic a–holes.” Stan meets up with everyone else at the hospital, where they deduce that Kenny has hidden a flash drive with vital information up his butt, which they reluctantly retrieve. We lost our tegridy, and it was all by design. (“Space Jam 2 came out, and we all just kind of… gave up. Randy later comes clean to Stan about the origins of the coronavirus - complete with his back-alley pangolin sex, which I had finally purged from my brain - but he attempts to spin it into being China’s fault, all part of their plan to rob America of its tegridy. As for Sharon, she couldn’t handle her daughter’s death, so she shot herself. Apparently Stan’s parents wanted a divorce after the pandemic, and because the farm was a major source of their conflict, Stan decided to burn it down… unaware that Shelly was in the barn. Stan confronts Randy at the Shady Acres Retirement Community, but his dad isn’t exactly thrilled to see him, as he blames Stan for both Sharon and Shelly’s death. “It’s a general sense of shellfish-ness,” he says. There’s a pretty amazing moment where Clyde explains that he doesn’t want to get vaccinated because he’s allergic to shellfish, so if someone who makes the vaccines happened to have recently eaten shellfish, it would be bad. Kenny’s on-record cause of death is a new strain of the coronavirus called COVID Delta+ Rewards variant, and since one citizen in South Park is revealed to be unvaccinated (way to go, Clyde!), everyone is forced to quarantine within the town limits. The gang concludes that Kenny must have been killed while investigating the origin of the coronavirus, a mystery which deepens when Stan discovers that his research leads back to Tegridy Farms. (Speaking of Cartman’s iconic look, turning his hat into a yarmulke was a stroke of genius.)īut the more everyone talks about Kenny, who apparently grew up to become a celebrated millionaire scientist, the more it starts to look like his death was no accident. And can you blame him? He’s likely traumatized from all those years of antisemitic bullying at Cartman’s mitten-covered hands. All of the usual suspects descend upon South Park for Kenny’s funeral, including Cartman, whose apparent conversion to Judaism doesn’t sit well with Kyle.
