provide continuous oxygen. This is a small portable tank on a wheeled cart (Fig. 28.3). You will need to know how to switch the patient from one type of source to another when you ambulate a patient in the hallway of the hospital. Patients at home may use liquid oxygen or oxygen con- centrators. When they leave home or move about the house, they can use a portable container called a stroller, which is light enough to be carried by the patient (Fig. 28.4). A portable oxygen concentrator runs on batteries and can be taken on airplanes. The patient can use continuous oxygen or something called pulse fl ow, which only delivers oxy- gen when the patient breathes in through their nose. The pulse fl ow is delivered in “equivalent liter fl ow” because it is not continuous. The number on the portable oxygen con- centrator for pulse fl ow is a setting, not a liter fl ow mea- surement. These types of strollers are not recommended for patients who need high- fl ow oxygen (greater than 4 L/ min). It is also recommended that the patient carry an extra battery with them because the portable oxygen concentrator
batteries only last 2 to 4 hours. Table 28.3 lists the types of oxygen sources along with a description of each. Oxygen is supplied from the source to the patient in a variety of ways. The nasal cannula, which has short, curved prongs designed to fi t inside the nostrils, interferes the least with eating and talking. It works best for patients who breathe through the nose. Masks of various types are used for different needs. Table 28.4 describes the different FIGURE 28.4 This patient is using a liquid oxygen stroller (from Wilkinson JM, Treas LS, Barnett, KL, et al.
