Body size

Body size is required to determine the body mass index (BMI). The BMI can be used to estimate nutritional requirements and provide suitable nutritional products.

My vital signs

On the History page, you will find the ‘My vital signs’ section. The vital signs display the data for height, body weight, body mass index (BMI), vital capacity of the lungs and peak cough in chronological order.

Body size

The current body height is displayed in the vital signs.

Enter your current height

Click on the ‘Adjust value’ button to open the input mask for the current body height.

BODY WEIGHT

Unwanted weight loss affects more than 50% of people with ALS. Weight loss can have various causes. A swallowing disorder with reduced food intake, an increased energy requirement due to respiratory dysfunction or an ALS-associated metabolic disorder can cause unwanted weight loss.

Body weight progression

On the” My vital signs” page, you will find the development of your body weight over time in the form of a progression diagram.

Body mass index (BMI)

Weight loss has prognostic significance in ALS and should be avoided or effectively treated through optimal nutritional care. Body weight and height are important when calculating energy requirements. The relationship between body weight and height is determined in the so-called body mass index (BMI). The BMI is calculated as body weight in kg/ (height in meters) ². For a person with a height of 1.7 m and a weight of 80 kg, the BMI is calculated as follows: 80 kg / (1.7 m)2 =27.7 kg/m2. A BMI below 18.5 kg/m2 is considered underweight and in need of treatment. The BMI is calculated in the ALS app, and the development over time is displayed in the vital signs. 

Development of the BMI

On the “My Vital Signs” page, you will find the development of your BMI over time in the form of a progression chart.

Vital capacity of the lungs

Vital capacity (VC) is a parameter used in lung function diagnostics. Reduced respiratory capacity can be determined using the vital capacity respiratory test. The CV measurement is a key value that is regularly determined in ALS outpatient clinics and used as a basis for deciding on possible treatment measures. VC can be measured in different ways: by breathing in and out quickly (FVC, forced vital capacity) or by breathing in and out slowly (SVC, slow vital capacity). The SVC value is displayed in the ALS app. 

Course of the vital capacity

On the “My vital signs” page, you will find the development of the vital capacity of the lungs over time in the form of a progression diagram.

A selection menu in the top right-hand corner allows the vital capacity of the lungs to be displayed over time as a diagram or table.

Click on the ‘Add value’ button to open the input screen for the current value of the vital capacity.

Coughing tip impact (PCF)

ALS can lead to impairment of the respiratory muscles. This can also be associated with a weakened cough. The weakness of the cough manifests itself in a reduction in the “coughing thrust”. The strength of the cough can be determined by measuring the peak cough flow (PCF). The peak cough flow indicates the maximum exhalation rate during a cough. In adults, it is normally above 270 l/min.

Course of the coughing spike

On the “My vital signs” page, you will find the progression of the cough peak values over time in the form of a progression diagram.
