why do individuals who are anemic generally not exhibit an increase in respiratory rate or tidal volume even though their blood is not carrying enough oxygen ? please answer in own words
Homework Answers
Chemosensitive respiratory centres are stimulated by increase in Carbon dioxide dissovled in plasma and decrease in pH.
In anemia there is either fall in no.of RBCs or Haemoglobin content or both,which decreases Oxygen carrying capacity of blood(as 97% of oxygen is carried by RBCs In bound form with Haemoglobin)
But gaseous exchange at tissue or alveoli level is not affected by it.As 77% of carbon dioxide and 3% oxygen is transported in dissolved form in plasma.
So till the time gases dissolved in plasma are not affected respiratory rhythm is not affected.

ABG problem. Patient has respirations of 22 breaths/min, is in respiratory alkalosis and is hypoxic. What interventions do you use to fix this problem? The answer is decrease tidal volume and decrease respirations. For some reason I can't wrap my mind around this. If the patient is hypoxic why would we want to lower tidal volume? and increasing respirations helps us to blow off CO2 and gain more O2, so why would we decrease it? this is what I know...

just circle the answer
Why do you think polar aprotic solvents increase the rate of an SN2 reaction? a) Polar solvents dissolve the substrates most effectively, speeding up the reaction b) Aprotic solvents better solvate the leaving group and therefore accelerate the reaction c) Aprotic solvents solvate the nucleophile less, 'naked' nucleophiles are more reactive d) Aprotic solvents raise the enegy of the reagents and therefore accelerate the reaction

Julie is a 52-year-old female who has come to a local walk-in clinic to discuss her COPD and specifically the problem she is having with exacerbations and time ‘off sick’. She is a heavy smoker, and her progressively deteriorating lung function suggests that she has moderate COPD, although she also has a history of childhood asthma, and had allergic rhinitis as a teenager. She has a sedentary office job and, although she is breathless on exertion, this generally does not...
