Patient Data Flashcards

1
Q

Ph

A

(7.35-7.45)

Important to diagnose diabetes and may be a indication for sodium administration

Determine CO2 retainer (COPD) if pH is normal when PaCO2 is high = COPD

Q

PaCO2^45 (35-45)

A

Not ventilating

You use to correct it

  • Ippb
  • mechanical ventilation
  • manual resuscitation (bag)
  • bipap
  • mouth to mouth
  • pressure support ventilation (PSV)

Q

Hb (12-16)

Difference between low Hb and high Hb

A

If Hb is low the patient is hypoxic regardless of PaO2 and SaO2 so give blood

High Hb above 16 is called polycythemia found in COPD pt’s

Hemorrhaging is a indication of blood loss and indicates supplemental blood should be given!

Q

VD/VT (20-40%)

Acceptable up to 60% if on a ventilator

A

The only calculation that relates to ventilation

Represents the percentage of the tidal volume that is unavailable for gas exchange

VD/VT=(PaCo2- PECo2)/ PaCo2 x100

Q

High dead space VD/VT

A

Relates to pulmonary embolus

PaC02 value comes from blood gas

PECO2 comes from end-tidal CO2 monitor (infrared device or capnography) or the Douglas bag

Q

CaO2

A

(17-20%)
Oxygen molecules in the atrial blood

Can be reduced by low Hb anemia or CO

CaO2 has the best relationship to tissues oxygenation

Q

CvO2

A

(14-16%) Oxygen retuning to the right side of the heart

Best place to obtain mixed venous blood is from the pulmonary artery

Decreasing values relate to decreasing cardiac output

Q

C(a-v)O2

Arterial-venous oxygen content difference from

A

(4-5 vol%)
C(a-v)O2= CaO2 - CvO2

Value increases as C.O decrease. (Inverse relationship)

CvO2 is dropping, cardiac output is decreasing. If the SVO2 or PVO2 is dropping while the arterial counterparts (SaO2 & PaO2) remain steady reduction of cardiac output can be assumed

Measure the oxygen consumption of the tissue

Q

PAO2

Alveolar oxygen tension

A

PAO2=((PB-PH2O)FIO2)- PaCO2/0.8

The alveolar air equation is the method for calculating partial pressure of alveolar gas (PAO2). The equation is used in assessing if the lungs are properly transferring oxygen into the blood.

Shortcut: PAO2=(O2%x7)-(PaCO2+10)
