EMS Chapters Flashcards
Airway - The passage by which air enters and leaves the body. Structures of the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs.
Chapter 8 - Airway Management
Bronchoconstriction - the contractions of smooth muscle that lines the bronchial passages that results in a decreased internal diameter of the airway increased resistance to airflow.
Chapter 8 - Airway Management
Stridor - A high pitch sound generated from a partially obstructed airflow the upper airway.
Chapter 8 - Airway Management
The main structures of the airway are the nose, mouth, pharynx., larynx, trachea, bronchi, and lungs.
Chapter 8 - Airway Management
Alveolar Ventilation - the amount of air that reaches the Alveoli.
Chapter 8 - Airway Management
Artificial Ventilation - Forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing. Also call Positive Pressure Ventilation.
Chapter 8 - Airway Management
Cellular Respiration - The Exchange of oxygen and carbon dioxide between cells and circulating blood.
Chapter 8 - Airway Management
Cyanosis– A Blue or gray color resulting from lack of oxygen in the body.
Chapter 8 - Airway Management
Diffusion – A process by which the molecules move from an area of high concentration to an area of low concentration.
Chapter 8 - Airway Management
Hypoxia –An insufficiency of oxygen in the body’s tissues.
Chapter 8 - Airway Management
Pulmonary Respiration–the exchange of oxygen and carbon dioxide between the alveoli and the circulating blood in the pulmonary capillaries.
Chapter 8 - Airway Management
Respiration – The Exchange of oxygen and carbon dioxide between the alveoli and the blood (Pulmonary Respiration) in between the blood and the cells (Cellular Respiration). Also used to mean simply BREATHING.
Chapter 8 - Airway Management
Ventilation – Breathing in and out (inhalation and exhalation), or artificial provision of breaths.
Chapter 8 - Airway Management
Breathing Rates:
Adult 12-20 /min
Child 15-30 /min
infant 25-50 /min
Chapter 8 - Airway Management
Ventilation Rates:
Adult 12-20 /min
Child 20 /min
infant 20 /min
Chapter 8 - Airway Management
BVM
- System must have a non-jam valve that allows an Oxygen inlet flow of 15 LPM
- The valve should be nonrebreathing and not subject to freezing in cold temperatures.
- Most systems have standard 15/22 respiratory fitting to ensure a proper fit with other respiratory equipment, face masks, and endotracheal tubes.
- BVM systems without a reservoir deliver approximately 50% oxygen.
- BVM Systems with a reservoir provide 100% oxygen.
- The bag itself will hold anywhere from 1002 1600 mL of air.
Chapter 8 - Airway Management
Oxygen cylinders:
When full pressure will be equal to 2000 to 2200 psi.
Chapter 8 - Airway Management
The following cylinders are common use care: D cylinder–350 L of O2 E cylinder–625 L of O2 Fixed systems on ambulances: M cylinder - 3000 L of O2 G cylinder–5300 L of O2 H cylinder–6900 L of O2
Chapter 8 - Airway Management
BVM WITH Reservoir = 100% Concentration BVM W/O Reservoir = 50% Concentration Non-Rebreather = 80-90% @ 12-15 LPM Nasal Cannula = 24-44% @ 1-6 LPM Partial Rebreather = 40-60% @ up to 15 LPM Tracheostemy Mask = 8-10 LPM
Chapter 8 - Airway Management
When performing mouth to mask ventilation on adult patient ventilations should be delivered over 1 second.
Chapter 8 - Airway Management
When fully pressurized, and oxygen tank should have approximately 2000 PSI on the gauge.
Chapter 8 - Airway Management
The portable oxygen cylinder that will last the longest in the field, of the choices listed is the E tank. An M tank is not a portable tank.
