A nasal cannula provides oxygen at adjustable flow rates in liters of oxygen per minute (L/min or “LPM”). The actual FIO2(percent oxygen) delivered by nasal cannula is somewhat variable and less reliable than with a mask but can be estimated as shown in the Table below as the accepted...

One study37 showed that in elderly patients, elevation of the respiratory rate can be the initial presenting sign of pneumonia, preceding other clinical findings by as much as 1 to 2 days. Indeed, tachypnea is present in more than 60% of all patients, being found more often in elderly ...
HFNC has been shown to deliver up to 1 mm of Hg of PEEP for every 10L/min of flow delivered with closed mouth breathing. (4-5) I’m not sure I believe this to be true of all patients, and this is because there are many factors that can affect how much PEEP can actually be ...
Case 1. A previously healthy 4-month-old infant is seen in the emergency department with a two-day history of coryza and poor feeding. On examination, he has mild/moderate subcostal recession and arespiratory rate of 60 bpm. His oxygen saturation in room air is 89%. Would you start nasal...
SARS-CoV-2 infection is associated with increased rates of hospital admissions and significant mortality. The pandemic increased the rate of cardiac arrest and the need for cardiopulmonary resuscitation (CPR). COVID-19, with its pathophysiology and detrimental effects on healthcare, influenced the ...
