23.	Consequences of acute and chronic bleeding (compensation)
Acute bleeding

e.g. circulatory shock

e.g. sideropenic anemia as a consequence of chronic bleeding

e.g. definition of anemia

37.	Glycaemia, its regulation and disorders

40.	Hyperhydration (types, causes and consequences)
isotonic hyperhydration

hypotonic hyperhydration

hypertonic hyperhydration

44.	Hypoxic hypoxia (causes and consequences)

Hypoxic hypoxia - V/Q mismatch

Cyanosis

45.	Hypoxic hypoxia; compensation and adaptation; mountain sickness

61.	Phases of hypovolemic shock
Phases of shock

62.	Pulmonary hypertension (causes and consequences)
https://www.wikilectures.eu/w/Pulmonary_hypertension

64.	Quantitative and qualitative disturbances of consciousness (overview)
Consciousness - quantity

Consciousness - quality

66.	Respiratory ABB disturbances
COPD

68.	Complications of shock states
e.g. decompensatory phase of shock

69.	Sleep apnea syndrome (central and peripheral type; consequences)
Comment: Obstructive Sleep Apnea (OSA) vs. Central Sleep Apnea (CSA) The point is, that in OSA during apnoic pause (no air flow from and out of the nose), you should see chest movement (there is obstruction in retroglossal space). In case of CSA, the problem is with the CNS respiratory centers and there is no obstruction, thus in case of apnoic pause (again no air flow), you will not see chest movement.

73.	Vegetative state, locked-in syndrome, brain death
Vegetative state = locked out

Locked-in syndrome

Brain death

74.	Ventilation control disorders
