Oxygen therapy

Early stages of hypoxia

restless, confused, anxious, vitals vary from baseline (elevated), dyspnea

Late stages of hypoxia

hypotension, bradycardia (lower vitals), metabolic acidosis, cyanosis (bluish discoloration of skin and mucous membrane)

Chronic hypoxia

clubbing, peripheral edema, right sided heart failure, respiratory acidosis, oxygen saturation >87%

Flow meter green collar

twist to release the flow meter

Flow meter cylinder portion

numbers and lines indicating how many liters of O2 are being delivered per minute (L/min)

Flow meter knob opposite the prongs

adjust flow rate , a ball goes up and down (wait for ball to align with dosage)

Nasal cannula

FiO2 is 24% to 44%, 1L to 6L, most often used, low flow, high flow,

Simple face mask

35 to 60% 5 to 10L , high oxygen flow preventing rebreathing of CO2, moderate flow rate

Nonrebreather face mask

80 to 95% and maintaining reservoir bag 2/3 full, high flow rates, high concentration of oxygen.

Venturi mask

224 to 60% 5 to 15L, fixed or predicted FiO2, critically ill, admin of specific concentration of O2 (5 adapters)

face tent

24 to 100%, at least 10L, alternative mask for claustrophobic pt,

Manual resuscitation bag

provide high concentration of O2, prior to procedure, during respiratory or cardiac arrest,

Oxygen tent and hood

approximately 50%, 10 to 15L, pediatric pt with airway inflam. Croup, respiratory infections

Tracheostomy mask/ collar

on trach site,

CPAP

positive airway pressure, sleep apnea, open up airway and presents upper airway from collapsing, 5 to 20cm of water, one continuous pressure

BiPAP

two continuous pressure, keeps airway from closing during expiration, increase in the amount go air in lungs at the end of expiration, reduced airway closure, improved oxygenation , non invasive ventilator, COPD

COPD pt are risk developing

hypercapnia and hypoxemia
