Section 1

Question Answer
Chemoreceptorscells found in carotid & aortic vessels which measures the levels of chemicals in arterial blood
Pre-LoadPressure by which blood returns to the heart
AfterloadPressure by which heart pumps blood out of the body
CO2 Medallary chemo receptors measure too much CO2 and medulla oblangata send message to respiratory musclesto breath in a healthy patient
Hypoxic Drivechemo receptors measure O2 levels fall then medulla oblangata send message to the respiratory muscles to contract
SurfactentOily substance found inbetween pleura and around alveoli
EcimosisBlue discoloration due to bruising
PercussionExamination of sound by striking
Coronary ArteriesBlood Vessels
Stroke VolumeAmount of Blood pumped in one beat
Tidal Volumeamount of air breathed in and out in one breath
Cardiac Outputamount of blood pumped in one minute
minute volumeamount of air breathed in and out in one minute
diastolic pressurepressure by which blood exerts against artery wall during cardiac relaxation
systolis pressurepressure by which blood exerts against artery wall during cardiac contraction
respirationgaseous exchange
ventilationmovemnet of air in and out of lungs
dead spacewhere ventilation occurs, but no respiration
Systemic Vascular ResistanceResistance offered to blood by constriction or dialtion of blood vessel

Section 2

Question Answer
2 Maneuvers to open airwayJaw thrust and Head tilt chin lift
How to maintain airwayOropharangeal Airway & Nasopharangeal Airway
Name 2 membranes of the lungVisceral Pleura and Parital Pleura
Describe Bloodflow to the heartSuperior Vena Cava & Inferior Vena Cava - Right Atrium - Right Ventricle-Pulmonary Artery-Pulmonary Vein-Left Atrium-Left Ventricle-Aorta
Describe Conduction System f the heartSino Atrial Node-Atrial Ventricular Node-Bundle of His-Left and Right Bundle Branch-Purkinje Fibers
Equation of Blood PressureCO x SVR
3 Layers of the heartMyocardium, Epicardium, Endocardium
Function of the Nasal CavityWarm, Moisten and Clean air entering the body

Section 3

Question Answer
3 parts of the upper airwayOropharynx, Laringopharynx, Nasopharynx
Primary SurveyHazards, Hello, Help, Airway, Breathing, Circulation
Secondary SurveyHead to toe, History, Package, Position, Transportation
Bechs TriadPericardial Tamponade & Tension Pneumothorax: Decreased BP, Muffles Sounds, Jugular Vein Distension
Symptoms of inediquate BreathingSpO2 less than 90%, Pt in tripod position, Cyanosis, Abnormal Breathing sounds, Accessory Muscle use, complains of dyspnea, not able to speak full sentences, pt has pursed lips and nasal flair, abnormal breathing rate.
Physiology of AsthmaSwelling, Secretion, Spasm of Muscles

Section 4

Question Answer
Airway Obstructionchoking, swelling
Bronchial Disruptionwhen bronchi tears off trachea
Diaphragmatic Tearwhen intestines move up in chest area
Esopahageal Injury
Open Pneumothoraxwhen air fills pleura - 1 lung collapse
Tension Pneumothoraxwhen air fills inbetween pleura - both lungs collapse
Massive Hemothoraxwhen blood fills inbetween pleura
Flail Chest2 or more ribs broken in 2 or more places
Cardiac Tamponadeobstructing Mechanical function of heart
Thoracic Aortic Dissection
Myocardial ContusionBruising of the heart muscle
Pulmonary ContusionBruising of the lung tissue
