cessation of breathing in the inspiratory position

38
Q

What is eupnea

A

quiet normal breathing

39
Q

What is hypernea?

A

increased breathing rate to meet need

40
Q

What is hyperventilation?

A

increase in ventilation in excess of need

41
Q

What is Dalton’s Law and the equation?

A

Partial pressure is directly related to the concentration of the gas in the atmosphere

Partial Pressure=(Percentage of gas/100)xatmospheric pressure

Percentage of gas=(Partial pressure of gas/atmospheric pressure)x100

42
Q

How is oxygen carried in the blood?

A
  • Dissolved in plasma (about 20%-arterial)

* Combines with hemoglobin (oxyhemoglobin)

43
Q

How is Carbon Dioxide carried in the blood?

A
  • Dissolved in plasma (about 10%)
  • Attaches to hemoglobin (carbaminohemoglobin-about 20%)
  • Transported as HCO3 (bicarbonate ion - about 70%)
44
Q

How are bicarbonate ions formed?

A

CO2+H2O => H2CO3 => H+ +HCO3-
