Older Adult Respiratory Assessment

When presented with a critically ill patient, it is crucial to conduct a systematic assessment of that person in order to identify and respond appropriately to any potentially life-threatening conditions (Smith & Bowden 2017).
When conducting a respiratory assessment, it is important to monitor changes in vital signs in order to recognise a deteriorating patient. You need to be familiar with what is normal so that you can distinguish what is abnormal (ACSQHC 2023).
Although the assessment procedure for older adults is similar to the one used for younger adults, there are some physiological differences between the two age groups that should be considered.
Generally, breathing and heart rates (resting) do not change much with age (MedlinePlus 2022). For a healthy, average adult, the normal rates are:
(MedlinePlus 2021)
Although vital signs do not change much with age, there is a gradual decline of lung function over time, starting from about the age of 35 (American Lung Association 2018).
The following are some of the physical changes related to ageing that may cause lung function decline:
(American Lung Association 2018)
These changes may cause tiredness or shortness of breath. Furthermore, a weaker immune system means older adults are more susceptible to developing pneumonia (American Lung Association 2018).
These changes are natural over time, however, they should be gradual and subtle. Sudden changes should be assessed by a healthcare professional (American Lung Association 2018).

If the older adult has a cognitive impairment such as dementia, it may be difficult for them to communicate, especially in emergency situations. Therefore, it is crucial to assess for the physical symptoms above in case the patient is not able to verbalise their needs (Dementia Australia 2017).
Early recognition of respiratory distress and deficit is vital to the successful management of sick patients and the prevention of further deterioration or arrest. In order to manage respiratory distress, it is important to have a systematic approach to assessment (Smith & Bowden 2017).
The ABCDE approach - Airway, Breathing, Circulation, Disability and Exposure - is a simple and effective method of assessment.
When assessing the airway, you should consider the following:

When assessing the breathing, you should consider the following:

Refer to How To Assess a Deteriorating / Critically Ill Patient (ABCDE Assessment) for a comprehensive explanation of the ABCDE assessment process.
You need to be aware of what is normal before you can recognise what is abnormal. It’s helpful to establish a baseline to compare progress or deterioration. Use a systematic approach, such as ABCDE.
The goal of assessment is not to make a diagnosis but to identify a deteriorating patient and respond to the symptoms in order to prevent arrest. Consider oxygen, suction and medication depending on the assessment (Resuscitation Council UK 2023).
Following the initial assessment (and resuscitation if required), a secondary structured assessment should be undertaken to identify any other key signs or symptoms (Resuscitation Council UK 2023).
When assessing the airway, the life threat to identify is airway obstruction. This is a medical emergency that may result in hypoxia, damage to the brain, kidneys or heart, cardiac arrest or death. It requires prompt management so that the patient can be oxygenated (Resuscitation Council UK 2023).

After about what age does lung function begin to naturally decline?
