Respirations
3 Parts
Perfusion
Flow of RBCs to and from the pulmonary capillaries
Diffusion
Movement of O2 and CO2 between the RBCs and alveoli
Ventilation
Movement of air between the atmosphere to the lungs
3 Important Aspects
Pulse Oximetry
Peripheral O2 Saturation (SpO2) is typically 92% -100%
Specific Blood Tests
Hematocrit Percentage
43% - 49% (males)
38% - 44% (females)
RBC Count
4.7 -5.74 x 10^12/L (males)
4.2 - 4.87 x 10^12/L (females)
Hemoglobin Count
135 - 180 g/L (males)
120 - 160 g/L (females)
Arterial Blood Gases
CO2 Partial Pressure
35 - 45 mm Hg
Blood pH
7.35 -7.45
O2 Partial Pressure
80 - 100 mm Hg
O2 Saturation
95% - 100%
2 Mechanics of Respirations
Inspiration/Inhalation
Involves:
Expansion of chest wall and abdominal cavity
Lowering of diaphragm
Expiration/Exhalation
Involves:
1.compression of chest wall and abdominal cavity
Rising of diaphragm
Normal/Expected Findings
Rate of respiration is between 12-20 breaths/min
