Sleeping respiratory (breathing) rate (SRR) is a very important parameter used for monitoring of dogs and cats with heart disease. Its biggest advantage is that it can be easily checked in home environment. Its increase is also one of the most sensitive indicators of fluid accumulation in the lungs or in the chest (i.e. development of heart failure).
Sleeping respiratory rate can be measured both before the first cardiology visit and as part of long-term monitoring of patients with diagnosed heart disease or heart failure.
How can I check my pet’s breathing rate?
- Wait till your cat or dog are calm and asleep (ideally at room temperature, i.e. they are not too cold or too hot). If your dog is barking or his/her legs are twitching, wait till they calm down as they might be having a wild dream.
- Count the number of breaths within one minute (minute respiratory rate) or within 15 seconds and multiply this value by four to get a minute respiratory rate. One breath is the animal’s chest going up and down (inspiration and expiration count as one breath).
- Measurement of the respiratory rate before the first cardiology visit should be done a few times within the two or three days prior to your appointment. In patients with diagnosed heart failure/heart disease the frequency of monitoring depends on the current clinical status of the pet as advised by the cardiologist.
- Please make a note of all your measurements (on a piece of paper or in your phone) and bring it to your appointment.
- Sleeping respiratory rate in dogs and cats can also be measured using a mobile app called Cardalis (counts the number of breaths in 30 seconds, minute respiratory rate is calculated automatically).
- Do not check your pet’s breathing rate when they are exercising, panting or are too hot or stressed/excited.
What is the normal sleeping respiratory rate in dogs and cats?
Normal respiratory rate in sleeping dogs and cats should not exceed 30 breaths per minute. In most cases it ranges between 15 and 25 breaths per minute. Sleeping respiratory rate that is permanently increased over 30 breaths per minute can indicate development of heart failure or deterioration of the pet’s condition. Increased respiratory rate can also be caused by other factors therefore a check-up by a cardiologist is always advised in these cases.
What shall I do if my pet’s sleeping respiratory rate is increased?
If your pet’s sleeping respiratory rate repeatedly measures higher than 30 breaths per minute, please contact your primary vet. He/she will be able to advise if you need to change your pet’s medications or if you need to see the cardiologist. If you feel your pet is struggling to breathe, contact your vet immediately.
