What are the three main determinants of oxygen supply
Give this one a try later!
- AVC membrane thickness
- Surface Area
- Driving Pressure
- Diffusion Coefficient
- vasodilation
- PP>40mmHg (wide)
- DBP<80mmHg (low)
- Flushed, warm
- Bounding pulses
- Quick Cap refill
- amount of oxygen present in the arterial blood when it leaves the lungs
- the capacity of blood to transport oxygen to cells
, - the effectiveness of the pump that circulates the blood throughout the
body
maximum air that can be exhaled after maximum inhalation.
useful indicator of persons ability to protect their airway
used for determining whether or not a person can be extubated

What components should be included in your assessment of
alveolar gas exchange
Give this one a try later!
- decreased PaCO2 - increased PaCO2
- alkalosis (ex; hyperventilation) - acidosis
- decreased temp - increased temp
- Vasoconstriction
- PP<40mmHg (narrow) - diffusion (4 factors)
- DBP>80mmHg (high) - V/Q match
- Cool, clammy, pale skin - PaO2, SaO2
- Weak pulses - Use of supplemental oxygen
- Decreased Cap refill

What cause a left shift on the oxyhemoglobin dissociation curve
Give this one a try later!
- Hgb level
Decreased mobility, abdo pain,
- Affinity (Shifts on the
nausea, vomiting, ischemic bowel
Oxyhemoglobin dissociation curve)
- circumferential chest burns - decreased PaCO2
- trauma - alkalosis (ex;
- rib fracture hyperventilation)
- spinal deformities - decreased temp

What chemical are central chemoreceptors triggered by
where are they located
what is their response
Give this one a try later!
- Norepinephrine [levophed] exerts its strongest action on alpha receptors
producing vasoconstriction
- it is a drug of choice for patients experiencing excessive vasodilation as a result
of sepsis for this reason
- PaCO2 levels
- their location in the brain puts them in close contact with CSF- CO2
diffuses rapidly across the BBB into the CSF
- stimulate the nearby respiratory centre (medulla and pons) to increase
ventilation (respiratory rate and tidal volume)
- PaO2 levels (only below 60mmHg)
- located in the carotid body and aortic arch
- receptors send a signal to stimulate increase in response rate and tidal volume
