Term
Tidal volume
Summary of normal breathing
Definition
Depth of breath = tidal volume

Normal- rate, rhythm, quality, and depth
Term
Physiology of breathing
Definition
CO2 levels rise in body, the need to exhaled is cued
Increased levels of CO2 in the body cause the brain to send a signal to the breathing muscles: the diaphragm & the inter stale. Movement of these muscles expands the chest & creates negative pressure causing the lungs to expand & air to enter thru airway.
Term
Alveolar
Definition
Tiny capillaries where gas exchange occurs. Capillaries release CO2 (cellular waste) into alveoli & blood cells absorb O2 which turns them bright red arterial blood. Increase level of CO2 in alveolar sacs signals the body to exhale.
Term
Inhalation
Definition
Active breathing, diaphragm contracts by flattening out & pulling down the abdomen; the intercostals muscles contract & open up the rib cage or thoracic cavity. Increased volume inside the vacuum of thoracic cavity, creates neg pressure, lungs expand, & fill a vacuum, air flows into the lungs thru airways
Term
Exhalation
Definition
Passive part of breathing
Diaphragm relaxes which brings it upward while the intercostal muscles release & the spaces between ribs become smaller. This reduces size of thoracic cavity, which causes pressure to expel air fr lungs.
Term
Signs of inadequate breathing

stridor high pitched coming fr upper airway during inhalation- may indicate blockage at larynx
Crowing = lower pitched noise noise heard upon exhalation
Wheezing = lower airway problem caused by asthma
Rales= fluid w/in alveoli of lungs, crackling sound is heard
Tho chi= snoring-like sound fr either upper or lower airway & is continuous, it may imply excess of mucous in airway

Term
Auctioning to clear airway
Definition
Sm obstruction, auctioning my clear it, is used to clear mucous, blood, blood, vomit, & fluid. 2 type of catheters 1. Tonsil tip - rigid tubes or 2. french tip - softer & flexible tubes.
Measuring:measured so it does not go past the base of the tongue
Soft/French tip - removing fluids from nasopharynx
Hard/tonsil tip - oropharynx & mouth preferable for removing small obstructions, as they do not collapse.
Term
Nasopharyngeal airways
Definition
(NPA) can be used on semi-conscious patients who have a gag reflex
Well-lubricated measured from tip of patient's nose to their earlobe.Insert by rotating airway back & forth in a spiral direction.
Term
Oropharyngeal airway
Definition
Upper airway adjunct is inserted thru mouth to assist in maintaining airway latency. Unconscious, can't be used on a patient w gag reflex it will cause vomiting.sizing by measuring from earlobe to teeth.
insert upside down slide bk of soft palate until resistance is met & so that it's base sits against the patient's teeth.
Term
Heimlich maneuver (abdominal thrusts)
Definition
Used to clear airway of conscious patient, not on pregnant woman, instead use chest compressions. Chest thrusts as used in CPR, can be used for pregnant women & are considered effective for dislodging obstructions from an unconscious person as they can be done concurrent w CPR ministering.
Term
Opening airway in infants patients
Definition
Assess breathing from distance before introducing the cold & scary stethoscope. watch for chest rise & fall;assess color & movement or lack of before handling infant. don't hyperextend head, use blow by O2 @ 6lpm. Suctioning w bulb syringe. when inserting OPA inset w tongue depressors in upright position, using rotation technique not to damage soft palate.
Term
Tidal Volume
Definition
Volume of air that is inhaled during a regular or normal breath.Measure of the depth of patient's breath. Hand on chest helps determine the amount of chest movement during respiration.
Term
Cricord pressure or Sellick maneuver
Definition
Preventative measure to block the esophagus & thus prevent gastric distention & vomiting during ventilation. used on unconscious patients, especially if they r receiving mask or BVM ventilation & endotracheal intubation can't be performed.
Technique: apply downward pressure to ring of cricord cartilage that lines the bottom of larynx., this blocks the esophagus & ensures ventilated air enters the lungs.
Term
Oxygen delivery equipmentb
Definition
Simple mask:6-10 liters,40-60% oxygen
Nasal cannula :1-6lpm or 20-40%
no rebreather masks 10-15lpm or 70-100%, 1way valve prevents from inhaling exhaled CO2.
Bag Valve Masks: BVM requires perfect alignment of patient's head
Term
Pulse Oximeters
Definition
Device used to determine the oxygenation of the blood in a non-invasive manner. In fared light absorption determine how red & how oxygen saturated the blood is over the period OD a pulse using the difference in infrared absorption between venous & arterial blood to determine the mat of O2 being used by the tissues.This does not monitor CO2 levels of the blood or ventilation in general.
Term
FROPVD
Definition
Flow restricted oxygen ventilation device is an oxygen powered device that can provide ventilation w/out physical input from the rescuer, it uses high pressure (50psi) to deliver oxygen thru a demand valve on a mask which is held in place by the rescuer. It can deliver 100% O2.Not used on patients w possible obstructions including COPD, patients w possible neck injuries, children, & infants.
Term
Recovery Position
Definition
Laying patient on their side w top leg & top side arm on the ground anteriorly to prevent the patient fr falling onto their back. Position allows drainage fr mouth & can prevent a patient fr choking on their vomit.
Term
Asthma
Definition
Allergic reaction or reaction to stress that causes the smooth muscle of bronchioles to contract; referred as bronchi spasm. Constricts the airway & may even completely block them. Production of excessive mucous can also block the airway further. The resulting symptoms can include coughing, wheezing, hypoxia & increased respiration respiration rate. Patient is likely be using accessory muscles to try to catch their breath, but are actually trying to expel trapped air. Asthma can be treated w brochodilater inhaler, since in an allergic reaction, epinephrine in inhaled form may be administered by med practitioners.
Term
Chronic bronchitis
Definition
Presents itself as a history of lung infections, excessive mucous that is loosened upon coughing, wheezing or tho chi & difficulty breathing due to inefficient gas exchange. Caused by in increased number of mucous cells. Their secretions smother the alveoli making it difficult for the capillaries to release CO2. both emphysema & chronic bronchitis r associated w smoking & may cause het failure.
Term
Bronchodilators
Definition
Dilated bronchioles allowing air movement to occur readily. EMT-B must have permission fr med officer to overseer to go ahead w the dose.
Term
CirculatorynSystem
Definition
Heart, arterial system & the venous system
Heart acts as pump that pushes blood to the lungs & then out thru the arteries, to arterioles & then capillaries where oxygenated blood is picked up by the cells.
Arteries r under pressure & have smooth muscle in their lining to help move blood along the capillaries.
Capillaries r midpoint between the arteries & veins at both the lungs & cellular level. Their twin walls allow for gas exchange, & the delivery of nutrients & the removal of waste products.
Veins: venous system low pressure, thin walls, w/out musculature.Venous system consists of veins, venues, & capillaries. Capillaries deliver deoxygenated blood to venues where it is moved along to the veins, carries blood bk towards the heart for re-oxygenation & removal of CO2.
Term
Cardiac chambers
Definition
2 aground, 2 ventricles. Atria receive blood, ventricles send blood.right atrium receives deoxygenated blood fr the Vena Cava, which is the final vein of the circulatory system. Blood moves thru the tricuspid atrioventricular valve into the right ventricle. Right ventricle pumps blood into the lungs the the pulmonic valve via pulmonary artery.
Oxygenated blood returns to hrt thru left atrium, flows down thru the mitral valve to the left ventricle & is pumped out thru the aorta thru to thebrest of the body via arteries.
Term
Aorta
Definition
Aka aortic arch or ascending aorta receives blood from left ventricle & distributes it thru the arterial system to the body; very thick-walled for high pressure.
Term
Pulmonary arteries
Definition
Receive blood from the pulmonary trunk & send it out to the lungs
Term
Pulmonary veins
Definition
Return oxygenated blood from lungs to left atrium
Term
Pulmonary trunk
Definition
Receives deoxygenated blood from the right ventricle and sends it via the pulmonary arteries to the lungs.
Term
Superior & inferior vena cava
Definition
Superior vena cava- returns blood from the upper body to the heart.
Inferior vena cava- returns blood from the lower body to the heart.
Term
Left & right coronary artery
Definition
Left coronary artery-returns blood from the upper body to the heart.

Right coronary artery-supplies blood to the right atrium.
Term
Coronary sinus
Definition
Received most of the deoxygenated blood from the heart muscle, receives blood from the great cardiac vein & the middle cardiac vein.
Term
Conduction system of the heart
Definition
Small % of cardiac muscle cells are auto rhythmic in that they contract continually, setting the beat for the rest of the heart muscle.
SA node produces electrical charge at top of rt atrium, produced by their contraction then moves to the Atrioventricular (AV) node, which lies on the wall between the rt atrium & rt ventricle. Signal produced in AV node is sent down the atrioventricular bundle, aka bundle of his, which lies between 2 branches are purkinje fibers, wh initiate the contraction of the ventricles fr the bottom up.
The result is recognizable double beat of the heart w the contraction of the atria staggered slightly, but perfectly fr that of the ventricles.
Term
Heart attack
Definition
Blood supply to heart muscle is blocked. Usually occurs @ left ventricle & results in damage to cardiac muscle.left ventricle pumps blood to rest of body, & receives oxygenated blood from the lungs via the right atrium. When it's musculature isn't working, blood pools in the left ventricle-called congestive hrt failure (CHF) & result in death. Symptoms:SOB, increased hrt rate, chest noises will be heard as blood & fluid accumulate in lungs.
Term
AMI -acute myocardial infarction
Definition
Result of hrt muscle not receiving blood due to a blockage of coronary arteries. As soon as blood supply to the hrt muscle or myocardial tissue stops, the tissue begins to die & this impairs the gets ability to pump blood.
Symptoms of hrt attack: tightening sensation or pain w/in the chest which can radiate out to the left arm, neck, & jaw. Patient can feel faint, nauseous & or short of breath. Pale, & damp skin, pulse rapids, slow or irregular, there will be a change in BP.
Term
Cardiogenic shock
Definition
Consequence of hrt attack, shock is physiological state of a body w/out enough blood supply. Tissue damage caused by initial hrt attack is spread due to the inefficiency of the muscle near the damaged area. The results similar to CHF as the hrt is unable to distribute the blood it receives, which builds up & backs up into the lungs.
Term
Cardiac arrest
Definition
Heart seizes to generate an effective beat to provide circulation, usually result of arrhythmias, hearts electrical impulse no longer functions & pulse is not produced. A patient can be conscious during a heart attack but once cardiac arrests occurs, they will no longer be conscious.
Muscle damage caused by a heart attack can lead to cardiac arrest lasting 4-6 minutes leads to to death due to brain damage caused by lack of oxygen to brain.
Term
Cardiac compromise
Definition
Catch all phrase that there are signs associated w heart condition.

Term
Hypotension ow BP
Definition
Low BP lower than 135/85 , feeling faint or dizzy & weak,
Causes: reduced blood volume, by blood loss or dehydration, or inefficient circulation which can be a result of impaired heart function or medications, some related causes are cardiac muscle damage due to disease or heart attack, valve malfunction or a malfunction in the conductive system of the heart.
Term
Angina pectoris
Definition
Chest pain that results in partial blockage of coronary arteries leads to poor blood supply to heart muscle. Reduced blood supply depletes oxygen available to the muscle cells ( hypoxia) & makes it hard for them to contract. Cramp in heart muscle, commonly occurs during times of physical stress when the heart is working hard & needs more oxygen.
Heart attack is complete blockage. Angina pain can be alleviated w nitro.
Term
Stable angina
Definition
1st occurrence of angina as a symptom of coronary artery disease CAD & resulting in Ischemia. Usually result of plaque build up in artery damaging the wall of the artery, this causes the body to try to heal it with blood clotting platelets. The scab that is formed increases the blockage even more, subsequently increasing the ischemia of the effected tissue.
Term
Variant angina
Definition
Or Prinzmetal's syndrome is a type of unstable angina where the diseased artery goes into spasm. Unstable angina is always a cardiac emergency.
Term
Atheroscleries
Definition
A form of arterriosclerosis where the walls of the arteries thicken due to an increase in smooth muscle fiber & fatty deposits known as plaque. This condition is often associated w coronary artery disease.
Term
Arterosclerosis
Definition
Disease which results in the hardening of arteries due to thickening & loss of elasticity.
Term
