Flight Follower (Dispatcher trained) makes sure the plan is safe, smooth transition
What we say to RT/RN when handing over patient
Coordinate with RT (Difficulty in intubation, view, Vent settings, [Mode of Ventilation, How much FIO2, What the SP02 is, ETCO2 is and the recent on that ABGs, PH, PACO2, PA02, Bicarb], ETT Size, Area at teeth, confirmed with X-Ray/RN (Sedation and drugs)/staff to facilitate the move to a bed.
Whats the alveolar gas equation
Alveolar gas exchange
- PAO2 = FiO2 (Patm−Ph20) −(PaCO2÷RQ)
- Ph20 Always = 47mmhg, RQ usually 0.8 (range 0.7-1)
Whats the blood oxygen equation
- CaO2 = (SaO2 x hgb x 1.34) +0.003(Pa02)
- 20.4 ml / 100 ml of Blood
What are the gas laws
Ideal pV = nRT
Boyles (pressure inverse to volume)
Charles (temp increases volume increases),
Dalton (total pressure = mixed pressures),
Gay-Lussac’s (pressure increased with temp)
Henry (coca cola can opening, the bends), partial pressure above a liquid
Graham’s law (Rate of effusion is inversely proportional to the square root of density)
Fick’s Law, Membrane thickness, driving pressure, Co-efficent of diffusion
What are the stages of hypoxia
Rememeber ICDC
Indifferent stage
90-98%
Minor Physiological effects
Can cause night vision loss above 5000ft
Compensatory stage
SP02 80-90%
Minute vent + Q (cardiac output) increase
Nausea, dizziness, lethargy, poor judgment, impaired coordination, and irritability
Disturbance stage
SP02 70-80%
Symptoms of hypoxia lead to impairment
Critical stage
SP02 60-70%
No longer able to do anything, inadequate function, incapacitation, unconc, death
What are the 4 types of hypoxia
Hypoxic hypoxia (Low Oxygen content) Low Pa02
Hypemic, Low carrying capacity/inability of blood to carry oxygen
Stagnant, No flow of blood to carry oxygen
Histotoxic, Toxic damage/inability of cells to pick up oxygen
