BackgroundIn adequately resourced clinical environments, diagnosis of hypoxemia via pulse oximetry is routine. Unfortunately, pulse oximetry is rarely utilized in under-resourced hospitals in developing countries.AimThe prevalence of undiagnosed hypoxemia among adults and children with illnesses other than pneumonia in these environments remains poorly described.MethodsThis cross-sectional analysis of the prevalence of hypoxemia was conducted in Kapiri Mposhi, Zambia, at the 60-bed District Hospital, which serves a population of 320,000. The resting room air oxygen saturations of two consecutive samples of all adult and pediatric inpatients were measured in December 2008 and March 2009 using handheld pulse oximetry. Hypoxemia was defined as resting room air SpO2 less than 90%.ResultsA total of 192 patients were enrolled: 68 young children (<5 years old), 15 older children (5–17 years old), and 109 adults (≥18 years old). Five young children (7%), 0 older children (0%), and 10 adults (9%) were hypoxemic. No hypoxemic patients were receiving oxygen therapy at the time of diagnosis. Pneumonia, tuberculosis, and malnutrition were the most common conditions among those with hypoxemia. Oximetry data changed clinical management in all observed cases of hypoxemia and several cases of normoxemia, leading to application of supplemental oxygen, initiation of further diagnostic testing, prolongation of inpatient stay, or expedited discharge home.ConclusionsUndiagnosed hypoxemia is present among inpatients at this district hospital in rural Zambia with high prevalence in both adults and young children. These results support routine screening for hypoxemia in similar facilities in both age groups. Further investigation is warranted into the clinical impact and cost-effectiveness of pulse oximetry, provision of oxygen concentrators, and training on their use in developing countries.

“…Although pulse oximeters give reliable readings of blood oxygen saturation for many clinical purposes, there are significant limitations on the accuracy and the availability of pulse oximetry data in some circumstances (FREUND et al, 1991;MOLLER et al, 1993;REICH et al, 1996). Pulse oximetry is a pulse dependent technique, and any significant reduction in the amplitude of the pulsatile component of the photoplethysmographic signal can lead to dubious values for blood oxygen saturation (SpO 2 ) or complete failure.…”

“…However, past studies have demonstrated a 7% to 9% failure rate with conventional pulse oximetry. 4,5 In most clinical settings, the pulse oximeter continuously monitors oxygen saturation levels but, in some settings, various factors (e.g., severe hypotension, low perfusion, or shivering due to hypothermia) interfere with accurate measurement. 2 Because these factors disrupt peripheral circulation, finger SpO 2 can be abnormal.…”
