CORONER’S LEGAL POWERS 

I make this report under paragraph 7, Schedule 5, of the Coroners and Justice Act 2009 
and Regulations 28 and 29 of the Coroners (Investigations) Regulations 2013.

INVESTIGATION and INQUEST 

Following an investigation opened on the 2nd March 2020 and an inquest opened on the 5th 
March 2020 the inquest was concluded on the 20th December 2022.  

The cause of death was: 

1a.) Immersion Pulmonary Oedema  
II.)   Hypertension and Menopause treated by Hormone Replacement Therapy  

The narrative conclusion was: 

Angela Jean Kearn was suffering from hypertension and taking hormone replacement 
therapy. On the 13th January 2020 she was snorkelling using a full face mask. She 
developed immersion pulmonary oedema and died at the Nile Hospial, Hurghada Egypt. 
Hypertension, hormone replacement therapy and the use of the full face mask each more 
than minimally contributed to the death

CIRCUMSTANCES OF THE DEATH 

i.) 

ii.) 

iii.) 

iv.) 

v.) 

Angela Kearn was aged 63 when she died. She had recently been diagnosed 
with hypertension which was being treated with atenolol. She was also taking 
hormone replacement therapy.  
For the previous 5 years she had been using a Decathlon  Easybreath full face 
snorkel mask when on holiday.  
On the 13th January 2020 she was snorkelling using the full face mask when 
she expressed concerns and was accompanied back to the beach. She 
collapsed and died.  
Expert evidence at the inquest identified immersion pulmonary oedema as the 
cause of the death. This is caused by the build-up of fluid in the lungs as a 
result of an increase in pulmonary capillary pressure caused by water 
pressure when the chest is submerged. This is exacerbated by hypertension 
and hormone replacement therapy. Negative pressure in the lungs causes 
fluid from the blood vessels to be drawn into the lungs.  
The use of a full face snorkel mask contributed to the death in two ways: 
a.) because negative pressure in the lungs is increased as a result of the 
increased effort of breathing caused by inhalation through the snorkel tube 
and mask, and  
b.)  because respiratory effort is increased by the inhalation of elevated carbon 
dioxide levels caused by inhaling air drawn through a dead space in the mask.

 Both exacerbate the negative pressure in the lungs and increase the effects of 
immersion pulmonary oedema.

CORONER’S CONCERNS 

During the course of the inquest the evidence revealed matters giving rise to concern. In 
my opinion there is a risk that future deaths could occur unless action is taken. In the 
circumstances it is my statutory duty to report to you. 

The MATTERS OF CONCERN are as follows: 

Awareness of Immersion Pulmonary Oedema in the medical profession: 

i.) 

Concerns were raised by the medical witnesses that there is very little awareness 
of Immersion Pulmonary Oedema in the medical profession and that it is not 
addressed in medical training, as a consequence, it can be missed by those 
treating the condition and is often mistaken for drowning.  

The Full Face Mask 

At the time that the Easybreath full face snorkel mask was developed by 
Decathlon there were no United Kingdom or European Standards which were 
applicable to a full face snorkelling mask.  
In the course of its development, Decathlon commissioned a number of tests to 
be undertaken on it, but it was accepted in evidence that the tests undertaken did 
not replicate the conditions of the use of the mask by the general public.  
Decathlon have sold over 16 million of the masks. Other such masks are also on 
the market.   
The Decathlon usage instructions for the full face mask, contained in small print, 
have been amended over time.  From the 17th August 2015 the instructions 
included a warning that you must make sure that you are in good physical 
condition before snorkelling and that the mask is not suitable for swimming.  
Further tests were undertaken and an Ergomedical report considered the issue of 
whether use of the mask and inhalation through the mask’s dead space gave rise 
to excess carbon dioxide inhalation. The report concluded “we strongly 
recommend to advise against wearing Easybreath masks to people who suffer 
from underlying cardio-respiratory conditions.” 
As a result, Decathlon amended their instructions for use to include that the mask 
should not be used if the user has unstable cardio-respiratory pathologies, that 
the mask is to be used under conditions of submaximal exercise (mild to 
moderate) and that it is not suitable for active swimming.  
Development of a United Kingdom standard in relation to this type of mask is now 
being put in train but has not yet begun and is likely to take some time.  
Decathlon have recently updated their website in the United Kingdom to include 
the following, “It is not recommended to use this product if you have any ongoing 
respiratory or cardiovascular issues including but not limited to chest infection, 
asthma, high/raised blood pressure (hypertension), heart disease or angina etc. If 
you have any doubts or questions relating to this please check with your medical 
practitioner." The same additional wording is being translated and added to all 
websites of the company. 
The packaging of the mask has been revised to show a pictogram to warn 
against use of the mask by those with heart or other cardiovascular conditions. 
The concern is that many million of the full face masks have been sold and the 
safety concerns about their use by those with ongoing cardiovascular and 
respiratory issues has not been widely publicised or brought to the attention of 
those who already own the masks. Those purchased before 2017 had no warning 
is relation to these matters and the warning included in the instructions from 2017 
inwards was not prominent nor sufficient to alert prospective purchasers to the 
hazards of use which have now been identified.

Miss Caroline Topping 
Assistant Coroner 
South-Eastern England- London Coroners Group 

Dear Miss Topping 

Regulation 28 report Angela Kearn 

I am responding on behalf of Professor 

. 

I am deeply sorry to hear of the untimely and tragic circumstances of Angela Jean Kearns’ death. I 
extend my deepest condolences to Angela’s family and those impacted by her death. 

Following an incident in Egypt, your report has raised concerns about awareness of ‘Immersion 
Pulmonary Oedema’ in the medical profession and that this condition is not specifically addressed in 
medical training.  

Through our standards and quality assurance of medical education and training we ensure that 
doctors in the UK are equipped with professional behaviours, knowledge, and skills to competently 
assess complex and uncertain acute and emergency situations. In addition, through professional 
clinical reasoning doctors are able to consider relevant differential diagnoses and manage acute 
medical emergencies including identifying people at high risk due to underlying comorbidities (such 
as Angela’s age and her history with hypertension). 

I hope the information above assures you that clinical knowledge and training is being assessed in 
areas that may intersect with Immersion Pulmonary Oedema and therefore if a doctor in the UK was 
to encounter a patient with this rare condition, they should have the tools and knowledge to be able 
to diagnose the condition and proceed accordingly with treatment.  

Whilst it is not the role of the GMC to comment on specific clinical practice, Immersion Pulmonary 
Oedema is a rare condition and its emergency presentation may be similar to other medical 
emergencies.  Its immediate management will also be similar and therefore we feel at this stage no 
further specific  education and training intervention would be required. Institutions such as the 
Medical Royal Colleges may be able to provide you with information related to the details for a 
process to identify and develop areas where learning is needed and can be shared in postgraduate 
training across the relevant specialties and subspecialties. 

The GMC is a charity registered in 
England and Wales (1089278) 
and Scotland (SC037750). 

 
 
 
  
 
 
 
 
 
 
 
 
 I note that this case happened in Egypt. We are not able to comment on the level of training or the 
medical education system in Egypt as that country is outside our jurisdiction.  

The GMC is committed to work with others in the health care sectors to improve training of the 
professionals we regulate so that doctors are better equipped with dealing with the variety of 
healthcare concerns and demands within the UK. To provide some context to medical education and 
training in the UK, I hope the attached annexe is helpful to you. 

Yours Sincerely 

Medical Director and Director of Education and Standards, GMC

 Our role as a medical regulator 
Our powers in medical education, as set out in the Medical Act 1983, are two-fold: to set the 
outcomes for graduates of UK medical schools leading to entry on to the medical register and to 
approve the curricula for postgraduate training of doctors. We quality assure both aspects of medical 
training against our standards for the management and delivery of medical education and training. 
The principle of patient safety drives our work. 

Undergraduate education 
Our powers don’t extend to mandating specific content in undergraduate curricula, but we 
determine and publish the high-level outcomes all medical students are required to demonstrate in 
order to graduate and be awarded a Primary Medical Qualification (PMQ). We updated our 
Outcomes for graduates in 2018 after extensive consultation. This is supplemented by a set of core 
Practical skills and procedures graduates must have achieved when they start work for the first time 
so they can practise safely.  

Foundation Programme 
All doctors enter the two-year Foundation Programme after graduating from a UK medical school. It 
provides new graduates with a range of essential interpersonal and clinical skills for managing acute 
and long-term conditions. The Academy of Medical Royal Colleges develops the Foundation 
Programme curriculum, which describes specific outcomes all Foundation doctors should 
demonstrate on completion of the programme. Our regulatory role is to approve the curriculum.  

The Foundation Programme curriculum requires first year trainees (FY1) to meet the outcomes we 
have set out in Outcomes for provisionally registered doctors with a license to practise, which 
includes fifteen core clinical and procedural skills. This enables the trainee to apply to the GMC for 
full registration and a license to practice, which is a requirement of entry to the second year of the 
Foundation Programme.  

Quality assurance of education and training 
We also have a duty to make sure medical education and training in the UK is meeting our standards. 
We expect organisations responsible for educating and training medical students and doctors in the 
UK to meet the standards set out in Promoting excellence: standards for medical education and 
training.   

We quality assure medical schools, postgraduate deaneries and local offices, and local education 
providers (such as NHS trusts and health boards) to check they are meeting our standards. Our 
quality activities are risk based, which means we look at our evidence and decide which areas are 
likely to be of concern. We provide feedback to organisations on how well we think they are meeting 
our standards. 

If we are concerned about something, we ask for more information to seek assurance that any issues 
are being dealt with appropriately, and if we're not satisfied with the response we can intervene.  

gmc.uk.org                                                                                                                                                                                                                        3 

 
 
 We can place organisations providing postgraduate training under ‘enhanced monitoring’, which we 
do to promote and encourage local management of concerns about quality and safety. This involves 
more frequent progress updates and we can provide representation on a locally led visit to 
investigate a concern or check on progress. Where possible we work with all organisations to 
address the concern and develop a sustainable solution. Sometimes we need to work with other 
regulators to make improvements.  

We also approve new medical schools, which we subject to an extensive period of quality assurance 
to ensure their programmes will deliver the Outcomes for graduates and meet the Promoting 
Excellence standards.

Dear Ms Topping, 

Regulation 28 Report – Angela Kearn 

We received the above report on 29/3/23.
his behalf. Firstly we would like to express our condolences to the family of Ms Kearn. 

 has asked me to respond on 

National Trading Standards (NTS) is not able to act on the issues raised in this report.  
NTS is a grant giving body that utilises Government grants to commission specified 
elements of Trading Standards related work from local authorities. Product safety does 
not fall within the scope of NTS. We do not receive any grants to commission work in 
this area. Issues surrounding product recalls and the Government lead for the safety of 
consumer products lies with the Office for Product Safety and Standards (part of the 
Department for Business and Trade). They work with local authorities on product 
recalls and we would recommend that, if it has not already been sent to them, that this 
report is sent to the Chief Executive of OPSS to respond. 

I am sorry that NTS is unable to assist directly. 

Yours Sincerely
