Q

What can these cause:
Hyperventilation (hypocapnia)
Entire neuromuscular chain for breathing must be intact
Respiratory center is pacing the chain to produce high minute ventilation

direct stimulation of medullary respiratory center
psych factors
(i.e pneumonia, pulmonary embolus, acute asthma)

Q

When will peripheral chemoreceptors make you breathe more?

A

16
Q
What is this:
Increase in EAP
Derangements in gut function
Derangements in metabolism
Due to exogenous intoxicants
Reduced net acid excretion due to renal defects
A

hypobicarbonatemia

17
Q

An imbalance between organic acid production and consumption creates what?

A

metabolic acidosis

18
Q

During hypoxia you willl have what?

A

build up of organic acids

19
Q

What does methanol and ethylene glycol (alcohols) cause?

A

acidosis (EAP-like)

20
Q

Virtually all causes of metabolic alkalosis present with (blank) or a least a low-normal K+.

A

hypokalemia

21
Q

vomiting or nasogastric drainage causes what?

A

metabolic alkalosis

22
Q

How come if you have an increase in HCO3, your pH stays normal?

A

metabolic alkalosis requires both a generation mechanism (vomiting) and a maintenance mechanism (increase in the renal threshold for HCO3 spillage)

23
Q

For every 10 mm Hg change in PaCO2 you will have a pH change by either .07 (acidosis) or .08 (alkalosis). What is this condition?

A

acute respiratory disturbances that HAS NOT been compensated

24
Q

IF you have a metabolic disturbance what fixes this?

If you have a respiratory disturbance what fixes this?

A

change in PaCO2

Change in HCO3 by kidney

25
Q

How many metabolic categories are there?

how many respiratory?

A

one

2 (acute and chronic)

26
Q

The body buffer compensation occurs (blank) and compensation by the renal system happens (blank)

A

quickly

slowly

27
Q

For every 10 mmHg increase in PCO2 and you have a decrease in .08 units in pH, what is this?

A

acute respiratory acidosis

28
Q

For every 10 mmHg increase in PCO2 you get a decrease in pH by .03, what is this?

A

chronic respiratory acidosis

29
Q

For every 10 mmHg decrease in PCO2 you get an increase in pH by .08, what is this?

A

acute respiratory alkalosis

30
Q

For every 10 mmHg decrease in PCO2 you get an increase in pH by .03,what is this?

A

chronic respiratory alkalosis
