EKG changes with calcium imbalances Answer - Hypercalemia : short QT
Hypocalcemia : long QT
Hypothermia resuscitation Answer - Withhold medications and defibrillation
until 30 C (86 F)
Rewarming sequence: Passive external, active external then active internal
Do not massage to warm body
Gravitational forces Answer - 1 G represents the force that a person exerts
when seated as the result of gravity
G forces are applied on descent, ascent, and during changes in speed or
direction
Positive G forces (ascent): blood pooling in LE, increased intravascular
pressures, & stagnant hypoxia
Negative G forces (descent): Blood pooling in upper body, HA, stagnant hypoxia
Vibration exposure Answer - Most common source in aircraft engine and
turbulence
Exposure to moderate vibration may result in:
fatigue
SOB
motion sickness
chest pain
, abdominal pain
Thermal effects Answer - Exposure to extremes in temperature may cause
increased
metabolic rate, oxygen demand, and oxygen consumption
S/S: Motion sickness
HA
disorientation
fatigue
discomfort
irritability
impaired performance
reduced ability to cope with other stressors such as hypoxia
Humidity effects Answer - As altitude increases & the air cools, humidity drops
Dried secretions may lead to airway obstruction, atelectasis and hypoxemia
Needle Cricothyroidotomy Answer - ●Hold the trachea in place and provide
skin tension with the thumb and middle finger of the non-dominant hand
placed on either side of the trachea. Use the index finger to palpate the
cricothyroid membrane.
In older children, adolescents, and adults: move the finger inferiorly into the
depression between the thyroid and cricoid cartilages
In infants and young children, palpate the trachea just above the suprasternal
notch and move superiorly until the prominence of the cricoid cartilage is felt.
●Hold a 3 to 10 mL syringe half-filled with saline attached to the over-the-
needle IV catheter in the dominant hand.
