Giving Oxygen to COVID-19 Patients in Kenya

Giving Oxygen to COVID-19 Patients in Kenya

According to the WHO, oxygen therapy is recommended for all severe and critical COVID‐19 patients. The ability to boost capacity to deliver oxygen therapy is the cornerstone of the overall approach to managing the COVID‐19 outbreak and it has implications for the functioning of the entire system. For these reasons, COVID‐19 treatment health‐care facilities should be equipped with pulse oximeters, functioning oxygen systems including single‐use oxygen delivery interfaces.

In a recent survey of emergency care centres across Kenya, over 30% of the facilities did not have a regular supply of oxygen. Close to 90% of those with oxygen did not have piped oxygen in the emergency department and delivered oxygen directly from the tanks to the patient.

Pipeline intra‐hospital oxygen distribution networks are helpful to supply oxygen at high pressure to equipment such as anaesthetic machines and ventilators or directly connected to patients with a flow-meter and tubing. A key advantage of pipeline systems is that they allow the distribution of oxygen to multiple patients simultaneously and obviate the need for handling and transporting heavy cylinders between hospital wards.

Installation Of Oxygen Gas Manifolds In Emergency Care Centres

“We now have piped oxygen for more patients in the emergency department and don’t have to keep rationing the oxygen for patients who need it” Emergency Nurse, Machakos Level 5 Hospital

Our oxygen gas manifolds are designed to supply the correct pressure and volume of oxygen from gas cylinders located outside the building through a pipeline system to the emergency department. The typical medical oxygen manifold commonly consists of four (4) sources and a manual changeover from empty source to full source and five (5) oxygen terminal outlets (sockets) installed in the emergency department. This boosts the capacity to deliver oxygen therapy from 1 oxygen tank per patient to 1 oxygen tank for up to 10 patients simultaneously.

The oxygen manifolds are specifically designed for optimal functionality and reliability, and offer users several very tangible advantages:

  1. Closed metal box, anti‐interference.
  2. The pressure of oxygen resource is stable and adjustable
  3. Pressure gauge displays make it easy to plan for refiling of the oxygen cylinders
  4. Continuous oxygen supply
  5. Multiple patients can receive oxygen simultaneously from one source

Help us do more

As the COVID‐19 pandemic continues to unfold here in Kenya, more and more patients will require oxygen. We have already installed an Oxygen Gas Manifold in the emergency departments at the  County Referral Hospitals in Machakos, Kiambu and Kajiado counties which are currently COVID-19 hotspots and we are in the process of installing more in the most severely affected Counties.

Each Oxygen Gas Manifold costs $ 5,175 and can be installed in 5 days. Your support will go a long way in ensuring emergency care centres across Kenya can handle multiple COVID‐19 patients and other emergency cases requiring oxygen simultaneously and potentially save more lives.

Oxygen therapy for acutely ill medical patients: a clinical practice guideline

What you need to know

  • It is a longstanding cultural norm to provide supplemental oxygen to sick patients regardless of their blood oxygen saturation
  • A recent systematic review and meta-analysis has shown that too much supplemental oxygen increases mortality for medical patients in the hospital
  • For patients receiving oxygen therapy, aim for peripheral capillary oxygen saturation (SpO2) of ≤ 96% (strong recommendation)
  • For patients with acute myocardial infarction or stroke, do not initiate oxygen therapy in patients with SpO2 ≥ 90% (for ≥ 93% strong recommendation, for 90-92% weak recommendation)
  • A target SpO2 range of 90-94% seems reasonable for most patients and 88-92% for patients at risk of hypercapnic respiratory failure; use the minimum amount of oxygen necessary

Mistakes that Kill during Cardiopulmonary Resuscitation

  • Too Slow or Too Fast Chest Compressions
  • Too Shallow or Too Deep Chest Compressions
  • Too Many or Too Slow Breaths
  • Leaning on the Chest
  • Too Many Interruptions
  • Giving Up Too Soon
  • Too Slow Adaptation


 

Oxygen Bubble Bottles or Bacteria Swimming Pools?

Humidified oxygen is widely administered in hospitals and EMS vehicles and this is presumed to alleviate nasal and oral discomfort in the non-intubated patient. Humidification of supplemental oxygen is commonly delivered by bubbling oxygen through either cold or warm sterile water before it reaches the patient. However, the effect on patient comfort is negligible. Bubble humidifiers may, however, represent an infection hazard and should not be used.

Oxygen Therapy

Always carefully titrate oxygen to the lowest tolerable level to meet the patient’s needs (SpO2 95%). Too much oxygen is associated with increased mortality in post-cardiac arrest, CVA, acute coronary syndrome, and traumatic brain injury patients…

Oxygen…THE DRUG!

DID YOU KNOW:

  • Hospital Oxygen is NOT FREE
  • At an SPO2 of 94%, additional oxygen is of NO BENEFIT. At this level, the standard dissociation curve is relatively flat, which means that the oxygen content of the blood does not change significantly even with large increases in oxygen.

Oxygen

  • Oxygen DOES NOT CURE DIFFICULTY IN BREATHING (DYSPNOEA), just HYPOXIA.
  • Oxygen should be delivered to achieve a target saturation of 94–98% for most acutely ill patients or 88–92% for those at risk of hypercapnic respiratory failure e.g. COPD
  • Humidification of supplemental oxygen commonly delivered by bubbling oxygen through either cold or warm sterile water before it reaches the patient should NOT be used because there is NO EVIDENCE of a clinically significant benefit but there is a risk of infection.

DOSE:

THX-63-Suppl_6

  • Nasal prongs delivers 4% additional oxygen per 1 litre of flow i.e. at 1L/min it delivers 24% (20% is already in the air), at 2L per min it delivers 28%, 3L/min 32%…and so on so at 6L/min it delivers 44%
  • A simple face mask should be used at a minimum of 6L/min (normal minute ventilation) to prevent the patient from breathing back their own CO2.
  • Application of a self inflating Bag-Valve-Mask on a patient’s face without compressing the bag is called suffocation. Due to the valves system, oxygen is only delivered ON COMPRESSING THE BAG
  • Pulse oximeters consist of two light-emitting diodes, one in the red range and one in the infrared range, and a detector.  Oxygenated and deoxygenated haemoglobin absorb light at different wavelengths differently. Deoxygenated or ‘‘blue’’ blood absorbs light maximally in the red band, whereas Oxygenated or ‘‘red’’ blood absorbs light maximally in the infrared band. The ratio of absorption of the two wavelengths of light are then compared with an algorithm in the microprocessor generated by empirically measuring the absorption in healthy volunteers at varying degrees of directly measured arterial oxygen saturation. The displayed value is usually an average based on the previous 3 to 6 seconds of recording.

HARMFUL EFFECTS:

  • Nonhypoxic heart attack victims treated with oxygen endure a 25 to 30% more heart damage than patients not given oxygen
  • Oxygen supplementation to nonhypoxic patients with mild or moderate strokes may increase mortality.
  • High-dose oxygen therapy to produce hyperoxaemia (above normal oxygen saturation) can cause absorption atelectasis
