Factors that affect O2 concentration delivered by manual rescitator
  • Adequate FiO2/flow to bag
  •  O2 resevoir bag used
  • Restricted or non restricted fill time
Components of Manual Rescusitator
  • Pt valve- directs O2 and CO2
  • Connector - 22mm outside/15mm inside
  • Pressure Limit Valve- Limit of 40 cmH2O on peds and infants
  • Self inflating- allows operator to feel airway changes
  • Inlet Valve- allow O2 in but can't escape
method to determine effectiveness of manual ventilation
  • Chest expansion
  • BBS
  • Pt Color
  • O2 sat
  • Easy Cap
ABG's
Describe Nasal Endotracheal tube
  • Can be done blindly, passed through nasal passage w/Macgill forceps, placed in trachea
  • Easier to stabilize and suction than oral tube
  • swallowing improved
  • bite block not needed
Describe Oral Endotracheal tube
  • Safest method
  • Used to relieve airway obstruction, protect airway, for suctioning and support ventilation
Describe Laryngeal Mask Airway (LMA)
  • Used when dangerous to manipulate thehead or neck
  • Does'nt protect from aspiration
  • Not inserted as far as ET tube
Explain function of Oropharyngeal airway
  • Two types Berman (I beam) & Guedel (Center channel)
  • follows natural curvature of tongue, seperates it from wall of pharynx
  • not tolerated well in conscious pts
  • flange at lips, tip should extend to angle of jaw
Explain function of Nasopharyngeal airway
  • provides passageway from nasal nares to base of tongue
  • flange at tip of nose extend distal tip to nose
  • beveled edge towards septum, advance straight back not up
Explain function of Tracheostomy tube
  • safest airway most desirable
  • easy to stabilize and suction
  • less airway restistence
  • pt can eat and drink
Equipment needed for oral intubation
  • Laryngoscope- Miller or MacIntosh
  • ET tube
  • Syringe
  • Stylet
  • Tape
  • scissors
  • Stethoscope
  • suction
  • ambu bag
  • easy cap
Equipment needed for nasal intubation
  • Magill forceps
  • vasoconstrictor
  • local anesthsia
  • NT tube
  • syringe
  • tape
  • lubricant
  • scissors
Characteristics of ET tubes
  • Bivana- cuff filled w/foam instead of air
  • Lanz- has pressure limt won't go over 18 mmHG
Why recommend Tracheostomy tube vs Endrotracheal tube
  •   Easier to suction
  • Pt can talk
  • Easier to stabilize
  • Pt can eat and drink
  • Less airway resistance
  • No bite block needed
Indications for Oral suctioning
  • Visible secretions
  • Gurgling sounds
  • Vomitus
Indications for Endotracheal Tube suctioning
  • Visible secretions
  • Sudden dyspena
  • Rhonci
  • Sudden increase PIP w/ mech ventilation
Indications for Nasotracheal suctioning
  • Most hazardous form of suctioning
  • Ineffective cough
  • Need to mobilize secretions from trachea
Complications of suctioning and clinical signs
  • Hpoxemia- O2 sat, tachycardia, brachycardia
  • Hypotension- brachycardia
  • Tracheitis- frequent suctioning
  • Infection- use sterile technique
