Finger Thoracostomy: Any pneumothorax in a patient undergoing positive pressure ventilation; Actual or near traumatic cardiac arrest; Shocked state with no apparent cause; Pleural drainage is not indicated in drowning or hangings unless pneumothorax is diagnosed. Remember pleural decompression will reduce the efficiency of the ACD and impedance valve
The most important extremity injuries are those that are either life-threatening or limb-threatening in nature such as Pelvic disruption with massive hemorrhage; Severe arterial hemorrhage; and Crush syndrome
OVERVIEW Definitions Flow = change in P/resistance Change in P = flow x resistance V = IR Voltage = the tendency of electrons to move through a conductive system (volts)Resistance = tendency of a material to limit flow of electrons…
Musculoskeletal compartment syndrome is a limb threatening condition resulting from increased pressure within a muscular compartment, which causes compression of the nerves, muscles and vessels within the compartment.
CLASS MECHANISM OF ACTION DIRECT:inhibition of Na/K ATPase on the cell surface-> increased intracellular Na+ and increased extracellular K+-> increased intracellular Ca2+ due to Na+/Ca2+ antiporter-> calcium-medated inotropy and increased automaticity, as well as negative dromotropy due to decreased intracellular K+ INDIRECT…
Renal replacement therapy (RRT): Troubleshooting
The work up of patients with sudden severe headache centers on excluding subarachnoid hemorrhage, however there are numerous other causes.

Ventriculomegaly is due to cerebral atrophy (e.g., Parkinson disease) or increased cerebrospinal fluid (CSF) within the ventricles.
Blepharospasm is uncontrollable blinking as a result of repeated involuntary orbicularis oculi contraction. It is always bilateral, but may briefly be unilateral at onset. It subsides when asleep.
