Factors affecting survival rates for drowning ✔️Length of submersion
Water quality (salty vs fresh)
Water temperature (submersion in cold/ice water fares better than warm)
Whether or not laryngospasm occurred.
Drowning vs drowned ✔️Drowning = process in which immersion/submersion prevents an individual
from breathing, resulting in respiratory impairment >> Thus, the word applies to any such incident,
whether or not the pt dies.
Drowned = always refers to a pt who died from drowning
Questions for drowning incident (determining MOI) ✔️Type of water, depth, temperature
Length of submersion
Trauma before drowning? (ie. jumping off cliff, boating accident)
What should pressure bag of hemodynamic monitoring be set at? ✔️Standard: 300 mmHg = allows for
the continuous flow rate of 3 ml/hr
, Benefit of art lines ✔️Accurate, continuous blood pressure monitoring with a waveform for visualizing
cardiac output
Arterial access for blood sampling.
Cuff pressure vs art line pressure, what is a normal amount of variation between the two? ✔️In a
normovolemic patient, there is usually a small discrepancy (5-10 mmHg is normal) between the "cuff
pressure" and the "arterial line" pressure.
When to check correlation between cuff pressure and art line pressure ✔️Usually examined:
- at insertion time
- the beginning of a shift
- any time when questions arise about the accuracy of the monitored value (e.g., dampened waveform,
monitor alarm).
Risks to art lines ✔️infection
Decreased tissue perfusion distal to the cannulated artery due to catheter migration or clot formation
Air embolus/blood clot formation
Hemorrhage
CVP ✔️Refers to the pressure created by the vol of blood in the R side of the heart.
CVP reflects R ventricular end-diastolic pressure or R preload.
Where are the catheters placed for CVP monitoring and art lines? ✔️Art - femoral, radial artery
