## What is Respi?

Respi-Rate is a practical application which helps healthcare professionals to determine the patient's respiratory rate.
 
The respiratory rate is usually determined by estimating or measuring the number of breaths at a certain time interval, followed by conversion to a one-minute respiratory rate.
 
With Respi-Rate, you only need to press the "Lungs button" – each time the patient starts to inhale. The application calculates the respiratory rate using its own innovative algorithm. 
 
METHODOLOGY DESCRIPTION
For example, the "Lung button" is pressed at 00:00 (mm:ss) and 00:05 – in both cases, when the patient starts to inhale. The interval between the first and the second breath is 5 seconds. The calculated RR, in this case, is 12 (60 seconds divided by the intervals, 60/5=12). 
The application takes the user's reaction time into account (the time between the start of the patient's breath and the pressing of the button in the application), and the standard deviation of the reaction time. Therefore, after each pressing of the “Lungs button", the application verifies whether the determination of the respiratory rate can be considered accurate. If not, then the application continues to define additional intervals so that the accuracy of the determined respiratory rate is at 95% ± 1 breath / min. with a regular breathing pattern.
 
For the most accurate calculation, it is important to keep pressing the button at the same stage of the breath cycle (for example when the patient begins to inhale). Do not use this application when the patient's breathing is irregular.
 
Please consult your doctor before making a medical decision.
 
Fast & simple. Enjoy the app!

### 5/5 — Works!

*2026-03-25, version 2.0.3*

Nice simple tool for getting breaths per minute. Used it for my cat.

### 5/5 — CFR great tool

*2024-03-13, version 2.0.3*

As a Community First Responder I find this app very useful for doing a quick first assessment. It should be followed by a full count for accuracy but it’s proved to be fairly close every time I’ve used it.

### 2/5 — Apple watch?

*2023-08-26, version 2.0.3*

I hope this is available on Apple Watch soon!

### 5/5 — Faultless.

*2023-05-06, version 2.0.3*

This app is faultless - simple and easy to use saving you and giving you an accurate resp rate - the large numbers allow you to show your crew mate without informing anyone in the room who may become panicky such as the Karen wife on scene who questions everything you do…

I’d like to know weather it is compatible with an Apple Watch, if so, I’ll go and buy an Apple Watch purely for this app - it’s that good. 

With the new developments in IOS I’d like to be able to add this as a widge, or if possible, like some app, have it appear on my Lock Screen when the app is active, so I can leave it open the in back ground and count someone’s resp rate without having to unlock my phone!

Everyone in my large ambo stn is getting this app send they are all love it. I’m looking forward to seeing what the devs come up with next!

### 5/5 — Reliable and easy to use

*2021-09-15, version 2.0.3*

### 5/5 — The best app ever!
