Airway Adjuncts: Maintain a patent airway Oropharyngeal- measure corner of mouth to earlobe. Patient must have no gag reflex. Use with a BVM, counters obstruction of tongue, facilitates suction. Doesn’t isolate trachea, can’t have clenched teeth. For pediatric use a tongue blade, it must be the right size Nasopharyngeal – measure tip of nose to earlobe, […]

Respiratory & Airway Part Four Assessing Intubation Placement – end tidal CO2 detectors Disposable colorimetric Electronic monitor Breath Sounds: listen for epigastric sounds after intubation. Apex of lungs right and left, mid clavicular right and left and mid axillary right and left Movement and Use of O2 in the Body depends on (Fick Principle): Adequate […]
Respiratory & Airway Part Three Exchange and Transport of O2 and CO2 Red blood cells (RBCs) – transport O2 and CO2 with a protein called hemoglobin FiO2 – concentration of O2 in inspired are. Pressure stays high in O2 (104) and low in CO2 (50) to make the O2 move across the alveolar/capillary membrane in […]
Airway & Respiratory Anoxia: Lack of O2 Hypoxia: low levels of O2 to the cells, reduced O2 supply to the cells, leads toanaerobic metabolism> metabolic acidosis> cellular depression> cellular death Treatment: O2, it increases the patient’s ability to compensate for the hypoxia Hypoxemia: insufficient oxygenation of the blood Atelectasis: alveolar collapse Compliance: stiffness or flexibility […]
Assessment Findings: Major focus is recognizing life-threats Altered mental status Severe cyanosis Absent breath sounds Stridor 1-2 word dyspnea Tachycardia>120/min Pallor, diaphoresis Use of accessory muscles Focused History Ever had this before, known pulmonary problems, ever been intubated, Medications, changes in medications Possible toxic exposures General Impression, evaluate the following Position- tripod position = moderately […]
