Case Study
Harold Jenkins is a 72 y/o male admitted to your med-surg unit for community-acquired pneumonia. PMH of hypertension, former smoker (40 pack-years). Mr. Jenkins is currently on room air; just returned to bed from ambulating to the bathroom. You come to bedside to perform a routine assessment.

Case Study
Mr. Jenkins has not been using his airway clearance devices regularly, reports using it "once or twice today." His SpO2 has been trending downward over the last 6 hours and is now requiring 6 L/min nasal cannula to maintain SpO2 88-92%

Case Study
You have instructed and encouraged use of the incentive spirometer. However, after 20 minutes Mr. Jenkins respiratory status has not improved. His SpO2 is <88% on 6 L/min nasal cannula. Place the appropriate oxygen delivery device on Mr. Jenkins to reveal the next passcode.

Case Study
You enter Mr. Jenkins room during afternoon rounds. He is on a simple mask at 10 L/min, appears anxious, is speaking in short phrases. The CNA says "He got more winded coming back from the chair"
Vital Signs
Based on Mr. Jenkins vital signs and current symtpoms, place Mr. Jenkins on the appropriate oxygen delivery device to get the next passcode.

FlowRate Chart
FlowRate Chart
Oxymizers require 1/2-1/4 flow rate of a standard nasal cannula Example: If a patient is on 2 lpm using an ozymizer, this is equivilant to 4 lpm using nasal cannula.
Case Study
Mr. James Renner, 68 y/o M presented to the emergency department with worsening dyspnea, productive cough, and fatigue over 4 days. At home, his oxygen saturations dropped to the low 80's despite increasing his nasal cannula to 4 L/min. PMH of severe COPD, HTN, HLD, 45 pack-year smoking (quite 5 years ago). Lives at home with spouse, ambulates independently with rest breaks, requires continuous oxygenation 2-4 L/min but manages ADLs. On Admission, J.R. vitals signs were 78% on 4 L/min Nasal cannula, RR 32 breaths/min, use of accessory muscles and ABG showed acute on chronic respiratory failure with hypoxemia and hypercapnia. He was admitted to the ICU for respiratory support. J.R. was initated on noninvasive ventialtion, which failed followed by intubation and mechanically venitaled. Diagnosed with acute COPD exacerbation with super mposed bacterial pneumonia. TX includes broad-spectrum IV ABX, systemic corticosteroids and aggressive pulmonary toileting. J.R was successfully extubated after 3 days. Mr. J.R. has since been downgraded to IMC, current respiratory support is High Flow Nasal Cannula (HFNC) SpO2 at 90-92% at rest. Multiple trials to transition from HFNC to standard nasal cannula at 4-6 L/min. Despite completion of ABX therapy, steroid taper and consistent pulmonary toileting, he remains unable to tolerate conventional nasal cannula, which is delaying dicharge to rehab or home. J.R. is clinically imporving but remains on HFNC, a modalitly not feasible for a med-surg level of care, home or rehab settings.
