Airway Management and Oxygenation Vocabulary

Vocabulary flashcards defining oxygen delivery systems, CPAP parameters, manual airway maneuvers, airway adjuncts, and end-tidal CO2 detection devices from the lecture.

Oxygen Tank Pressure

The internal pressure of an oxygen tank, which is $2\,000\,\text{psi}$ and can transform the tank into a speeding projectile if dropped.

Low-Flow Oxygen Device

An oxygen delivery device, such as a nasal cannula, that operates at flow rates up to $6\,\text{L/min}$.

BVM (Bag-Valve-Mask)

The mandatory oxygen delivery choice when a patient is not breathing adequately, operated at $15\,\text{L/min}$ for testing purposes.

CPAP Criteria

Indications for administering CPAP to a medical shortness of breath patient, requiring the patient to be conscious, breathing adequately, having adequate blood pressure, and presenting equal lung sounds.

CPAP Pressure Settings

The pressure levels delivered by CPAP devices, measured as $5\,\text{cm}$, $7.5\,\text{cm}$, and $10\,\text{cm}$ of water column.

PEEP (Positive End-Expiratory Pressure)

The positive pressure remaining in the lungs at the end of exhalation, maintaining chest pressure higher than external atmospheric pressure.

Head Tilt-Chin Lift and Jaw Thrust

The two manual hands-on techniques used to open a patient's airway.

OPA (Oropharyngeal Airway)

A BLS airway adjunct indicated for unconscious patients, sized from the earlobe to the corner of the mouth.

NPA (Nasopharyngeal Airway)

A BLS airway adjunct indicated for semi-conscious or snoring patients, sized from the earlobe to the tip of the nose.

iGel

An advanced supraglottic airway device permitted in California BLS scope of practice for adults, sized by patient weight in adult sizes $3$, $4$, and $5$.

Colorimetric Device

A basic inline $\text{CO}_2$ indicator that visualizes exhaled carbon dioxide by changing color between yellow and purple to confirm airway patency.

Inline $\text{CO}_2$ Monitor

A battery-powered or monitor-integrated device attached to an airway that provides a continuous numerical end-tidal $\text{CO}_2$ value and waveform.

Biological Death Sign in CPR

A progressive decline and ultimate disappearance of exhaled $\text{CO}_2$ during resuscitation, signaling that cellular respiration has permanently ceased.
