In the dusty villages of Bihar, India, a community health worker named Sunita Devi presses her stethoscope against a toddler's chest and begins counting breaths. She is following the World Health Organization's Integrated Management of Childhood Illness (IMCI) protocol, which for decades has trained frontline workers to diagnose pneumonia by measuring respiratory rate. The cutoff is clear: a child under five breathing 50 times per minute or more likely has pneumonia and needs antibiotics or referral. But Sunita Devi also has a pulse oximeter in her kit—or rather, she is supposed to. At many primary health centres (PHCs) across Bihar, these devices remain locked in cupboards, their batteries never installed, their screens dark.

The Breath Counter vs. The Device

Bihar, one of India's poorest states, accounts for roughly 15% of the country's under-five pneumonia deaths. The state's 90,000 or so Accredited Social Health Activists (ASHAs) are the backbone of community-level child health. Each ASHA covers a population of about 1,000 and is trained to recognize danger signs, including fast breathing. The WHO IMCI algorithm, updated as recently as 2025, recommends both respiratory rate counting and pulse oximetry for diagnosing pneumonia and assessing severity. Yet a 2024 survey in Bihar found that only 12% of severe pneumonia cases received pulse oximetry before referral.

The gap is not for lack of devices. India's National Health Mission has procured roughly 1.2 million pulse oximeters since 2020, distributing them to PHCs and sub-centres. In one PHC in Muzaffarpur district, a researcher counted 20 oximeters in a locked cabinet—none had been used in the past year. The breath counter, meanwhile, remains the default tool. ASHAs like Sunita Devi can assess a child's respiratory rate in under a minute using a simple timer. But studies show that breath counting alone misses about 15% of hypoxemic children—those with dangerously low blood oxygen levels who need immediate oxygen therapy.

The WHO's 2025 pneumonia management algorithm places oximetry as the first step after assessing for danger signs. In practice, many ASHAs have never been trained on the device. A 2025 assessment in Uttar Pradesh, another high-burden state, found that only 34% of sub-centres had functional oximeters. The rest had either no device, dead batteries, or a device that staff did not know how to use.

Why Oximeters Stay Unopened

The reasons are multiple and interlocked. First, consumables: pulse oximeters require batteries, which are not always supplied. In many PHCs, the budget for batteries is separate from the device procurement budget, and the paperwork to request new batteries can take months. Second, training: a 2023 study by the Public Health Foundation of India found that 40% of districts had not trained ASHAs on oximetry. The typical ASHA training lasts 23 days and covers dozens of topics; oximetry is often squeezed into a single session.

Third, fear of breaking equipment. ASHAs are paid modest incentives—roughly 2,000–5,000 rupees (US$24–60) per month—and are often held personally responsible for lost or damaged devices. One ASHA in Samastipur district told researchers, "If I break the oximeter, they will deduct from my pay. I cannot afford that." Fourth, supervision: district health officers rarely check whether oximeters are being used. A 2026 audit in Jharkhand found that 18% of pneumonia deaths had no record of oximetry, and in most cases, the device was still in its box.

The result is a paradox of plenty: devices accumulate in storerooms while children die of hypoxemia. In one PHC in Gaya, a district with high pneumonia mortality, the medical officer in charge said he had 20 oximeters but had not opened a single one in 2025. "We have no training," he said. "The ASHAs don't ask for them."

Counting Breaths: The Evidence Base

Breath counting is not useless. The WHO threshold of 50 breaths per minute or more for children aged 2–12 months predicts hypoxemia with about 70% sensitivity and 80% specificity, according to a 2024 meta-analysis in The Lancet Global Health. That means it catches roughly 7 out of 10 hypoxemic children. But the remaining 3 are sent home with a false sense of security. Silent hypoxia—low oxygen without obvious fast breathing—is well documented in pneumonia. A child may have chest indrawing, grunting, or lethargy, but if the respiratory rate is below 50, the ASHA may classify it as no pneumonia and advise home care.

The 2024 Lancet study, which pooled data from 14 countries including India, found that combining breath counting with oximetry raised sensitivity to 92%. The number needed to screen to prevent one death was estimated at roughly 200 children—a cost-effective intervention given that a basic pulse oximeter costs US$20–30. But the study also noted that training on oximetry is essential: in settings where ASHAs were taught to use both tools, misclassification dropped by half.

The evidence for oximetry is not new. A 2012 trial in Bangladesh showed that community-based oximetry reduced pneumonia mortality by 35%. India's own operational guidelines, updated in 2023, mandate oximetry for all pneumonia cases. Yet the translation from guideline to practice remains stubbornly slow. As Dr. Vinod Kumar, a public-health researcher at the Public Health Foundation of India, put it, "We have the evidence. We have the devices. What we don't have is the system to make them work."

The Implementation Gap

India's 2023 operational guidelines for child health are clear: every child with fast breathing or chest indrawing should have oxygen saturation measured. If saturation is below 90%, the child should be referred for oxygen therapy. The National Health Mission has spent roughly US$30 million on pulse oximeters since 2020. Yet a 2025 survey of 1,200 sub-centres in Uttar Pradesh found that only 34% had a functional oximeter. Among those with functional devices, only half had a staff member who could demonstrate correct use.

The gap is not unique to India. A 2026 WHO report on 10 low- and middle-income countries found that oximetry was used in only 22% of pneumonia consultations in primary care. But India's scale makes the gap particularly consequential: with roughly 1.2 million under-five pneumonia deaths globally each year, India accounts for about 400,000—one-third of the total. Closing the oximetry gap could save an estimated 80,000 lives annually, according to modelling by the Johns Hopkins Bloomberg School of Public Health.

Why does the gap persist? Partly because procurement and training are handled by different government departments. The device arrives at the PHC, but no one has told the ASHAs how to use it, no one has supplied batteries, and no one has built a system for maintenance. The result is what health-system researchers call a "supply-demand mismatch": devices are pushed into facilities without the accompanying support to make them usable. As a district health officer in Bihar said, "We have oximeters. But we also have a shortage of nurses, a shortage of oxygen concentrators, and a shortage of time. The oximeter is the least of our problems."

ASHAs themselves are overstretched. Each covers roughly 1,000 people, and their duties include family planning, immunization, tuberculosis screening, and maternal health. Adding oximetry to their toolkit without reducing other tasks is unrealistic. A 2026 time-motion study in Bihar found that ASHAs spent an average of 12 minutes per child with pneumonia symptoms—barely enough to count breaths and check for danger signs. Adding oximetry would add another 2–3 minutes, which in a busy clinic may feel like an eternity.

When Guidelines Meet Ground Reality

The WHO 2025 pneumonia algorithm, released in draft form, lists oximetry as the first step after ensuring the child has no immediate danger signs. But in practice, many ASHAs skip it. "I count breaths because that is what I was taught," Savita Kumari, an ASHA in Bihar's Gaya district, told researchers. "The oximeter is for the doctor." The problem is that the doctor may not be at the PHC either. In many rural sub-centres, the ASHA is the only health worker present. Children with silent hypoxia are sent home with advice to return if symptoms worsen—by which time it may be too late.

A 2026 study in Jharkhand, published in the Indian Journal of Pediatrics, reviewed 200 pneumonia deaths in children under five. In 18% of cases, there was no record of oximetry at any point in the care pathway. Among those who had oximetry, 72% had saturation below 90% at the time of measurement, indicating severe hypoxemia. The study concluded that earlier detection—at the community level—could have prevented most of those deaths.

The gap between guidelines and reality is not just about devices. It is about how guidelines are written. The WHO algorithm assumes a well-stocked clinic with a trained nurse and a reliable power supply. In rural Bihar, power cuts are common, and the nearest referral facility may be two hours away. ASHAs make triage decisions under time pressure, with limited support. As Savita Kumari put it, "I have to decide in five minutes whether this child needs to go to the hospital. If I send every child with fast breathing, the hospital will be overwhelmed. If I send none, some will die."

The tension is real. Oximetry could help, but only if it is trusted and used. In some districts, early pilots of community-based oximetry have shown promise. In Ranchi, Jharkhand, a program that trained ASHAs to use solar-powered pulse oximeters and linked oximetry use to a small performance incentive (roughly 50 rupees per child screened) increased oximetry coverage from 5% to 70% within six months. But scaling such pilots faces familiar barriers: funding, political will, and the sheer inertia of a health system that has functioned without oximetry for decades.

What Can Close the Gap

The solutions are not mysterious. First, integrate oximetry training into ASHA refresher courses. India's Ministry of Health runs a biannual refresher training for ASHAs; adding a half-day module on oximetry, with hands-on practice using a dummy finger, would cost little but require commitment from state health departments. Second, assign dedicated oximeter maintenance at the block level. A single block-level technician could check batteries and calibrate devices across 20–30 sub-centres, reducing the risk that devices become unusable.

Third, use simple pulse oximeters with solar charging. Many rural PHCs lack reliable electricity; solar-powered oximeters, which cost roughly US$30–40, can last for years without battery replacement. A pilot in Madhya Pradesh found that solar oximeters were used in 80% of pneumonia consultations, compared to 20% for battery-only models. Fourth, link oximetry use to performance-based incentives. ASHAs are already paid for certain tasks—bringing children for immunization, completing tuberculosis treatment. Adding a small payment for each oximetry screening could drive uptake, as the Jharkhand pilot showed.

Fifth, pilot community-based oximetry in high-burden districts. The government of India has launched a "Pneumonia Free Villages" initiative in 100 high-burden districts, but oximetry is not yet a core component. Including oximetry in the package—along with oxygen concentrators at referral facilities—could demonstrate impact and inform national scale-up. The evidence from Bangladesh and India's own pilots suggests that community-based oximetry can reduce pneumonia mortality by roughly 20% if implemented with training and support.

Trade-Offs and Counter-Arguments

But there are trade-offs. Critics argue that adding oximetry to ASHAs' workload without reducing other tasks could lead to burnout or lower quality of care. Others point out that oximetry alone is not enough: children with hypoxemia need oxygen therapy, which is often unavailable at PHCs. Referral to a hospital with oxygen may take hours, and many families cannot afford the cost of transport or treatment. Oximetry without a functioning referral system may simply identify children who cannot be saved.

These are legitimate concerns. But they are not reasons to abandon oximetry. Rather, they argue for a systems approach: oximetry as part of a package that includes training, maintenance, referral, and oxygen supply. The alternative—continued reliance on breath counting alone—means accepting that one in seven hypoxemic children will be missed. For the families of those children, the cost of an unopened oximeter is measured in a life.

Furthermore, some health officials argue that breath counting is already adequate for most cases, and that the marginal benefit of oximetry does not justify the logistical burden. However, the evidence suggests otherwise: even in settings where respiratory rate is measured accurately, silent hypoxia remains a significant cause of mortality. A 2025 study in the Journal of Global Health found that among children with pneumonia who died, 30% had a normal respiratory rate at presentation, meaning they would have been missed by breath counting alone.

Another counter-argument is that oximetry may lead to over-referral, overwhelming already strained referral hospitals. Indeed, in the Jharkhand pilot, oximetry increased referral rates by 40%, but the majority of referred children did not require oxygen therapy. This suggests that oximetry alone, without a clinical algorithm that accounts for other signs, may not be cost-effective. However, the WHO algorithm already integrates oximetry with clinical signs, and training can help ASHAs interpret oximetry results in context.

Finally, there is the question of sustainability. Many global health interventions fail because they rely on external funding and short-term projects. Oximetry programs must be embedded in routine health budgets and supply chains. A 2026 analysis by the World Bank estimated that integrating oximetry into India's existing ASHA program would cost an additional US$0.50 per capita per year—a modest investment that could yield substantial returns in lives saved.

The Cost of a Locked Closet

Each unopened pulse oximeter represents roughly US$20–30 in wasted procurement. Over 1.2 million devices, that is US$24–36 million—a significant sum in a cash-strapped health system. But the opportunity cost is larger. Child pneumonia kills roughly 1,200 children under five each day in India, according to UNICEF estimates. Modelling studies suggest that universal oximetry coverage could reduce that number by 20%, saving 240 lives per day. Even a more conservative estimate—a 10% reduction—would save 120 lives daily.

Breath counting alone is insufficient for severe cases. The WHO's own guidelines acknowledge that respiratory rate is a moderate predictor of hypoxemia, and that oximetry is the gold standard. Yet in practice, breath counting remains the primary tool, not because it is better, but because it is simpler. The gap between evidence and practice is not a knowledge gap; it is an implementation gap. The devices exist. The training materials exist. The evidence exists. What is missing is the will to close the loop.

A 2026 cost-effectiveness analysis in BMJ Global Health estimated that scaling community-based oximetry in India would cost roughly US$50 per child screened and save US$200 per death averted—a net saving. The analysis assumed that oximetry would be used alongside breath counting, not replace it. The combination is more accurate than either tool alone, and the marginal cost of adding oximetry is low once the device and training are in place.

The locked closet in Muzaffarpur is a metaphor for a larger problem: a health system that procures technology but does not build the infrastructure to use it. The same pattern is seen with brachytherapy machines in Angola and heart failure vials in Malawi. Devices are not enough. They need people, training, consumables, and supervision. Until that reality is accepted, devices will continue to gather dust while children die of a treatable disease.

Sunita Devi will keep counting breaths. She has no choice. But the next time she sees a child with chest indrawing, she may wonder: what if the oximeter in the locked closet could tell her more? The answer is clear—but the system has not yet found a way to let her open it.
