,A right shift means - ✔✔hemoglobin is giving tissue O2 freely, higher
PaO2
A shift to the right means that hemoglobin has what? - ✔✔less affinity for
oxygen so it gives it up freely; right releases, left latches
End product of aerobic cellular metabolism - ✔✔carbon dioxide
What disease is an abnormality in hemoglobin? - ✔✔sickle cell anemia
Physical exam order for respiratory system - ✔✔inspect, palpate, percuss,
auscultate
slower than 12 breaths per minute - ✔✔bradypnea
faster than 20 breaths per minute - ✔✔tachypnea
Faster than 20 breaths per minute, deep breathing - ✔✔hyperventilation
frequent interspersed deeper breaths - ✔✔sighing
Increasing difficulty in getting breath out - ✔✔air trapping
varying periods of increasing depth interspersed with apnea - ✔✔cheyne-
stokes

, Rapid, deep, labored - ✔✔Kussmaul
irregularly interspersed periods of apnea in a disorganized sequence of
breaths - ✔✔biot
significant disorganization with irregular and varying depths of respiration
- ✔✔ataxic
If a patient has malignant hyperthermia what happens to their body? -
✔✔CO2 and heart rate rise
Describe hyperresonance - ✔✔loud/booming; may indicate asthma,
emphysema, or pneumothorax
Describe tympany - ✔✔loud/drum-like; may indicate large pneumothorax
or emphysematous blebs
Describe dullness - ✔✔Could indicate atelectasis, pleural effusion,
pulmonary edema, pneumonia
Flatness on auscultation could indicate - ✔✔massive atelectasis
