Hi Guys! This is a 1 of the four (4) simple php scripts for identifying the pediatric vital signs. 

Below is the code for Blood pressure chart. Watch out for other vital sign scripts that i will post next. Okay, enough of the chit chat blah blah blah. Below is the php code

function blood_pressure_chart($age,$rate) {    
$rate = explode("/",$rate);    $systolic = $rate[0]; 
// upper number    $diastolic = $rate[1]; 
// lower number    
// School Age    
if($age>=6 && $age<=9) {       
 if(($systolic>=97 && $systolic<=115) && (($diastolic>=57 && $diastolic<=76))) 
{            return 'Normal';        }    
    else {            return 'Abnormal';        }   
 }    // Pre-Adolescent    
else if($age>=10 && $age<=11) {     
   if(($systolic>=102 && $systolic<=120) && (($diastolic>=61 && $diastolic<=80))) {  
          return 'Normal';        }      
  else {            return 'Abnormal';       
 }   
 } 

   // Adolescent    else if($age>=12 && $age<=15) {      
  if(($systolic>=110 && $systolic<=131) && (($diastolic>=64 && $diastolic<=83))) {       
     return 'Normal';        }     
   else {            return 'Abnormal';        }  
  }   }

Basic Usage:

echo blood_pressure_chart(12,'120/80'); // Output: Normal
