ARDS - phases
- Exudative: capillary congestion, alveolar necrosis…
- Proliferative: type 2 pnuemocyte, macrophages
- Fibrotic/Resolution: scar tissue and restructuring
ARDS
diffuse alveolar damage
noncardiogenic pulm edema
hypoxemia
ARDs - causes
- direct lung injury - pneumonia, trauma
2. indirect lung injury - sepsis, burn, pancreatitis
Post-Op Respiratory Failure
- atelectasis
- pneumonia
- pulmonary edema
- PE
PE - Classic Triad
dyspnea, chest pain, hemoptysis
PE - etiology
popiteal thrombi, gyne surgery, indwelling cath, hypercoag (HTN)
Pulmonary HTN
- primary- idiopathic
2. secondary- cardiac, pulm
SCI - Intro
- NT release - inflammation
- vascular injury- hematoma, ischemia
- microhemorrhage in gray matter
- edema- dec blood flow, ischemia
- spinal shock - hypotension
Central Cord Syndrome
- hyperextension
- greater motor impairment in upper vs lower
Sacral Sparing
- preserved voluntary rectal sphincter
2. perianal sensation
Anterior Cord Syndrome
- hyperreflexion
- m + s loss below site of injury
- fine touch preserved
Brown-Sequard
- penetrate one side’
- motor loss same side
- sensory loss opposite side
Spinal Shock
- transient
- initial HTN, then HoTN, loss motor fxn, muscle flaccidity, etc
Neurogenic Shock
-HoTN, brady, hypothermia
Autonomic hyperreflexia
- uncontrolled CV response from SNS
- paroxysmal HTN, h/a, brady
- full bladder and bowel
Parkinsons’
substantia nigra, dopa
Guillian Barre
AI myelin in PNS
Myasthenia Gravis
AI ACh receptors
