what can shift the O2 dissociation curve to the right?
|
increases in blood PCO2, temp, and 2,3 BPG, decreases in blood pH
|
|
| 3 |
what is P50?
|
the PO2 value where hemoglobin is 50% saturated with O2
|
|
| 4 |
how do you treat carbon monoxide poisoning?

inhalation of 100% O2 or hyperbaric O2
|

| 7 |
how does the vagus nerve impact breathing patterns?
|
information from the lungs carried in vagus nerves stops inspiration and promotes expiration

central apnea
|
brain respiratory centers do not effectively drive respiratory muscles
