CAMATA Cht. 3 Patient Care In Flight – Questions
With Verified Solutions
Oxygen and Respiration Correct Answer - oxygen is obtained
from environment and delivered to tissues for utilization

External Respiration;
-Gas exchange in the lungs

Internal Respiration;
-Gas exchange at the cellular level

Tissue Oxygenation Correct Answer - Tissue oxygenation
depends on;

-Healthy lungs
-Healthy heart
-Patent blood vessels
-Healthy blood
-Receptive healthy tissues and cells

O2 transport Correct Answer - 3% dissolved in plasma

97%-98% carried on hemoglobin

Normal ABG results Correct Answer - Po2 80-100
Pco2 35-45
pH 7.35-7.45
Hco3 22-26

Hypoxia S/S Correct Answer - Altered loc
Tachy/Brady
Hyper/Hypotension

, Seizures
Dyspnea
Cyanosis
Headache
Visual disturbances
tingling/numbness
euphoria/anger
changing judgement
hot/cold flashes

Hypoxic Hypoxia Correct Answer - Reduced gas exchange at
alveolar- capillary level
(Pulmonary dysfunction, altitude)

Hypemic Hypoxia (anemic) Correct Answer - Reduced oxygen
carrying capacity of blood
(anemia, hemorrhage, CO poisoning)

Stagnant Hypoxia Correct Answer - Reduced oxygen delivery
to tissues
(shock, arterial occlusion or spasm, G-forces)

Histotoxic Hypoxia Correct Answer - Inability to use O2 at
tissue level
(CO, some OD's (ASA), alcohol, or cyanide poisoning)

Oxygen Administration Correct Answer - As altitude increases,
O2 needs increase
-O2 needs should be calculated prior to flight to ensure adequate
supply for the entire transport, esp for long transports

Altitude O2 requirement equation Correct Answer - Fio2 X
AP1/AP2 = Fio2
