Oxigenation Flashcards
Movement of gases between air spaces and blood stream
Diffusion
Movement of air in and out of lungs
Ventilation
Exchange of oxygen and Carbon dioxide
Respiration
Movement of blood into and out of lungs to organs and tissues
Perfusion
CNS sends signals to chest walls to control rate, depth and rhythm.
Neural regulators
Carbon dioxide and hydrogen ions affect rate and depth of ventilation.
Oxygen transport.
Dissolved in plasma, carb amino compound, bicarbonate.
Carbon dioxide transport.
Inadequate tissue oxygenation at the central level.
Hypoxia
Inadequate ventilation to meets the body demand.
Hypoventilation.
Increase the respiratory rate.
Hyperventilation
Hypoxia is a life threatening, which are the causes of hypoxia.?
Anemia. Atelectasis. Cardiomyopathy Carbon monoxide poisoning Septic shock Cyanide poisoning, head trauma Pneumonia, spinal cord injury,
Atelectasis and collapsed alveoli can cause
