Q

What is type 1 respiratory failure?

A
  • too little oxygen
2
Q

What is type 2 respiratory failure?

A
  • too little oxygen

- too much carbon dioxide

3
Q

Define hypoxaemia?

A
  • low levels of O2 in blood
4
Q

Define hypercarbia?

A
  • high levels of CO2 in blood
5
Q

What causes respiratory acidosis?

A
  • high levels of CO2
6
Q

Vaso_______ is used.to try match VQ when V is much lower than Q

A
  • Vasoconstriction
7
Q

What are the chemoreceptors responsible for respiratory rate in a normal person?

A
  • CO2 chemoreceptors
8
Q

What causes hypoxic drive?

A
  • chronic hypercarbia
  • loss of sensitivity to co2 chemoreceptors
  • o2 chemoreceptors drive respiration
  • too much o2 give –> reduction in response rate
9
Q

define shunting?

A
  • perfusion without ventilation
10
Q

define dead space?

A
  • ventilation without perfusion
