Deteriorating breathlessness at a sub-centre with limited oxygen
At 6:45 p.m. at a sub-centre, a 68-year-old woman is brought by her son with worsening breathlessness for two days. She has a known history of COPD and hypertension and takes tablets irregularly. She is sitting upright, speaking in two-to-three-word phrases, and is slightly drowsy. Your readings: respiratory rate 30/min, SpO2 87% on room air with a fingertip pulse oximeter, pulse 116/min irregular, blood pressure 168/98 mmHg in the right arm, temperature 37.9 °C. The probe is cold and the patient's fingers are cold and blue-tinged; the reading is unchanged after 30 seconds. The sub-centre has one oxygen cylinder with about half its contents, a nasal prong and a simple face mask, but no arterial blood gas facility. The medical officer is 40 minutes away by road, the 108 ambulance is 25 minutes away, and the family wants to take her by car to a private hospital 20 km away. There is no written advance directive.
1. Which finding is the most urgent, and how would you confirm that it is real before acting on it?
Read the worked answer
SpO2 87% on room air, with a respiratory rate of 30 and drowsiness, is the most urgent finding. It suggests hypoxaemia and impending respiratory failure. The raised blood pressure and irregular pulse are important but not immediately life-threatening in the same way.
Before acting, confirm the reading is real. Cold, blue fingers and a cold probe can underestimate saturation. Warm the hand, clean the probe site, remove nail polish if present, and repeat on a different finger. Also look at the patient: speaking in two-to-three-word phrases, drowsiness and use of accessory muscles support genuine hypoxia. A single abnormal number is not a diagnosis; a number plus the clinical picture is. Even if the repeat reading is 90%, her work of breathing and drowsiness make this an emergency.
2. Outline your immediate management and transport decision, explaining why the private car is not the best option.

Sit her upright, start oxygen by nasal prongs at 1–2 L/min and titrate to 88–92%, because she has known COPD and higher concentrations can worsen carbon dioxide retention. Reassess every few minutes.
Call the medical officer now and request the 108 ambulance rather than a private car. She needs oxygen and monitoring during transfer, and a car cannot provide that. Explain this to the family in simple words. If they still refuse, document their preference and the advice given. Do not send her alone or without a referral note. If she becomes more drowsy or stops responding, support the airway and continue oxygen while awaiting transfer.
The judgement is to act on the most dangerous abnormality first and not to wait for the doctor to arrive before giving oxygen or arranging transfer.
3. What exactly will you document, and why does the sequence of events matter?
Read the worked answer
Record the time of each set of observations, the probe site and repeat values, the oxygen flow and her response, her position, her mental state, the advice given to the family, the time the medical officer and 108 were called, and the referral decision. Write objective facts and the actions taken. Sign the entry and hand over verbally to the ambulance crew.
Documentation protects the patient and shows the sequence of decisions if her condition deteriorates. It also shows that oxygen was titrated appropriately for COPD and that the family was advised against private transport. The reasoning is that a clear timeline supports continuity of care and is essential if the case is reviewed later.
