Oxygen Therapy
What is the tank factor for an E cylinder?
What is: 0.28
What PPE is used for CONTACT PRECAUTIONS
What are: Gloves and Gown
What drug class is DuoNeb?
What is: B2 agonist and anticholinergic
Reasoning: DuoNeb is made up of Albuterol and Atrovent (AKA Ipratropium)
pH: 7.42 PaCO2: 38 HCO3: 24
PaO2: 95 (on 21% FiO2)
What is: A normal Acid-Base Balance with No Hypoxemia
What are the 3 modes of NIV?
What are: CPAP, BiPAP, and AVAPS
A patient is on a 36% AEM. What is the equivalent flow on a nasal cannula?
What is: 4 LPM
What PPE is used for droplet precautions?
What are: Gloves, mask, and face shield
*Some facilities also require gowns
What antibiotic is commonly nebulized for Cystic Fibrosis?
What is: Tobramycin (Tobi)
pH: 7.55 PaCO2: 23 HCO3:26
PaO2: 30 (on 60% FiO2)
What is: Uncompensated Respiratory Alkalosis with severe hypoxemia
What are the primary indications for CPAP?
What are: OSA and refractory hypoxemia
*Refractory hypoxemia is a PaO2 < 60 on 60% FiO2
What is the equation for total flow?
What is: [(100-FiO2)/(FiO2-21)]+1 x flow
*Use 20 for FiO2 >/=40
What PPE is used for airborne precautions?
What are: Gloves and an N-95 respirator
*Some facilities require gowns
**If an N-95 does not fit an employee they can use a PAPR (Powered Air Purifying Respirator)
What is: Breakdown of disulfide bonds
pH: 7.13 PaCO2: 58 HCO3: 14
PaO2: 54 (on 100% FiO2)
What is: A Combined acidosis with severe hypoxemia
*Can also be referred to as a mixed acidosis
What are 3 contraindications of NIV?
What are: Copious secretions, inability to remove mask, apnea, severe acidosis, severe hypoxemia, diaphragmatic paralysis, inability to protect airway, pneumothorax, facial trauma, uncooperative patient
What are hazards 3 of O2 therapy?
What are: O2 toxicity, nitrogen washout, absorption atelectasis, oxygen-induced hypoventilation, impairment of the mucocilliary escalator
With which disease MUST you wash your hands when leaving the room?
What is C-Diff
What drug is used to treat Pneumocystis Pneumonia?
What is: Pentamidine
pH: 7.02 PaCO2: 8 HCO3: 6
PaO2: 104 (on 21% Fio2)
What is: A partially compensated metabolic acidosis with hyperoxemia
*Commonly seen in DKA
What are 3 indications for BiPAP/AVAPS?
What are: hypercapnia, increased WOB, hypoxemia, neuromuscular disease, OHS, CSA, CO2 retainers (during sleep), cardiogenic pulmonary edema, thoracic cage abnormalities (kyphoscoliosis, etc)
What are 3 indications for O2 therapy?
What are: Suspected hypoxemia, PaO2 < 60, SpO2 < 90%, chest pain/MI, tachycardia, trauma, surgery, increased WOB
What is the proper order to put on ALL PPE?
What are: cap and booties, gown, mask, eye protection, and gloves
What drug should NEVER be mixed with Albuterol?
What is: Formoterol
Reasoning: Mixing a Laba (formoterol) with a Saba (Albuterol) can cause bronchoconstriction.
pH: 7.20 PaCO2: 75 HCO3: 34
PaO2: 75 (on 40% Fio2)
What is: Acute on chronic raspatory acidosis with moderate hypoxemia
An ABG for a patient on BiPAP (20/5 with a set RR of 12 and total RR of 16) shows respiratory alkalosis. What setting should be changed?
What is: the IPAP should be decreased
*Decreasing RR could be a potential answer but the IPAP is more appropriate in this scenario
